View Full Version : Debunking the Stundies - March Edition
William Rea
4th April 2007, 12:49 PM
Having enjoyed debunking two of the March "Stundie" Awards Voting Nominations I am starting a thread away from the normal "Stundies" activities to debunk the basis of any nominations that do not stand up to their stated aims.
In the same spirit as the "Stundies" this thread is not restricted to analysing any particular side of the debate in preference over the other but, its content will reflect the nominations put forward in the "Stundies".
I am interested in comments from people who have gone back and reviewed "Stundie" nominations and found the quotes taken completely out of context. This is an opportunity to redress the lack of impartiality of any quotes.
NOTE - I cannot emphasise enough that this thread is not for flamers, if you have nothing to add to the analysis then avoid it. By the same token I will no longer involve myself in any of the "Stundies" threads leaving everyone to have their version of fun as they see fit.
Undoubtedly there are elements who will not welcome this thread and will do everything within their power to disrupt & personalise it and so get it moved out by the Moderation. Time will tell but, I think it's worth the effort.

Because this video was recorded by who-knows what camera (could have even been a crappy one, such as a camcorder), I doubt the person who recorded gave the original footage to the person who posted it on the internet, so most likely he recorded it from a TV. After that, he send it to the computer. After that he compressed it by an enormous degree to allow fast internet replay. And after that it was posted on YouTube (or GoogleVideo) where it looses even more resolution. And after that someone made a screen capture of the already crappy footage and in most cases blew up the image to focus on the plane.
If you know about videos and graphics, you'll know that every step of the translation of the recording makes the video loose resolution. So the NPTers are basing their "evidence" on already faulty videos.

I'm very much more interested in your agreement with David Ray Griffin that "...gravitational energy...is vertical..."
Let's go back to Griffin's quote:
"...gravitational energy, which is vertical..."
When an object is suspended above the ground:
Its position (height) is vertical
The gravitational force acting on it is vertical
Its gravitational potential energy IS NOT VERTICAL
When the object is dropped:
Its displacement is vertical
Its gravitational acceleration (g) is vertical
Its kinetic energy IS NOT VERTICAL
You may as well argue that the object's mass is vertical.
Griffin is mixing up fundamental physics concepts. If he weren't making (or repeating) claims about how the twin towers should have collapsed without the aid of explosives, it would be no big deal. But he is (and he has many avid followers) so it is.
Zdenek Bazant represents energies with vectors in his analysis.
???
This I gotta see. Show us some quotes with citations.
I decided to get out of this thread to stop you all whingeing about me posting in it. :D
So you couldn't find any references to Bazant saying energy was a vector?

Not sure I agree with your claim that Killtown was responding to an intervening post--note the word "normal" in quotes, which Jarroyo never uses. On the other hand, it certainly could be argued that Killtown was asking for a link to a site selling a "normal" video. So I think you're right that this should not have been included in the list.

That's pretty much the definition of ignorant. He's a theologian, presuming to discuss physics at a level where he can claim that other's analyses can be dismissed as "magic", and yet he knows so little of the topic, he cannot even use the correct terminology.
This is aside from his glossing over how a downwardly directed force can result in lateral movement, provided there is some mechanism to redirect the effect of the force. He simply ignores the fact that these particular beams were not acting solely under the influence of gravity, but were also interacting with all of the masses around them.
So, ignorant, and willfully blind. Pure Stundie material.

Your arguments would carry more weight if you'd link to such examples. Some people in these discussions have misrepresented what was said earlier so often and so badly, that we simply cannot accept such assertions at face value.
Note, I said, "a downwardly directed force can result in lateral movement, provided there is some mechanism to redirect the effect of the force".
Consider a wedge being forced sideways under a weight. The sideways force can produce an upward movement of the weight, as the wedge acts to re-direct the effect of the force. There are losses (due to friction, and whatnot), but the principle is sound.

If someone wants to offer some balance, or an opposing view, or defend or debunk the Stundies, that's fine with me. Not because it's the Stundies and I don't like them, but because that's what happens on just about every other thread in the JREF forum.

Jarrayo is suggesting that the available video being used for analysis has degraded so much that the surface of the building looks smooth. He then goes on to speculate how the degredation might occur implying that there might be an original source video. That original source might be considered the "normal" condition for investigation.
Justifiably Killtown asks how to obtain this "normal" video.
The use of "normal" with the quotation marks indicates a sense of irony in the use of the word. I suggest that the poster is raising a question mark about what a "normal" video might be. To me this positively indicates he is aware that this source may not be available via a normal bit streaming source.
For some reason I cannot see the original post but killtown quoted Jarrayo in his reply so I can only infer he was responding to him/her.

Thank you for the good wishes, I already suspect I will need them.
I am endeavouring to go legit so to speak so, I will refrain from responding in kind to obnoxious posts. In a way it is a test of myself and the forum to see if it is really possible to engage in a more positive manner.

I agree that context should be provided for the Stundies. It's only fair, after all, as Twoofers are regularly castigated for taking quotes out of context.
Of course, this won't reduce the number of nominees that much. There are plenty of in-context outrageous things said by Twoofers every day.

Yes. He makes it quite clear that he believes that GPE can contribute ONLY to a vertical force vector.
2. It actually shows a little insight into how Gravitational Potential Energy acts and releases in a vectorial manner.
This statement actually gives us a little insight into how little you understand the concept of GPE. It in no way "releases in a vectorial manner." That makes absolutely no sense. It shows no insight on Griffin's part at all. Everyone knows that gravity makes stuff fall down. His confusion about the physics behind it is embarrassing.
3. In its correct context it is neither ignorant nor illogical nor fallacious, the man just doesn't have the knowledge of scientific language to express himself. Despite this he clearly shows an understanding of how it works.
:yikes: In its full context, it's even clearer that he has NO IDEA how it works. Let's see that again:
"At the onset of each tower’s collapse, steel beams were ejected out as far as 600 feet; to believe that these horizontal ejections could be explained by gravitational energy, which is vertical, is to believe in magic."
He not only vectorializes (it's a word, I swear) energy, but also implies that NONE of the GPE in a collapsing structure can be spent on lateral force components (except by "magic").
Judging by this sentence alone, he is completely inept in the realm of physics.
4. Other scientists and engineers express energy and conversions in similar terms.
So you say. Examples? Found that Bazant quote yet?

In comment to your post, I am being told that energy has no vectoral element so it appears that whilst it is apparent that everyone knows that gravitational energy makes stuff fall down this is simply not so.

Please refer to the section on page 14 that analyses the Potential and Kinetic Energies and related equations.
I cannot find your reference text.
It's on page 5 of the pdf. Search on "inertia force", it was the first hit I got.
This is the full paragraph:
Deceleration and Acceleration During the Crushing of One Story. The two intersections of the horizontal line F = gm(z) with the curve F(u) seen in Fig. 3 and 4a (top) are equilibrium states (there is also a third equilibrium state at intersection with the vertical line of rehardening upon contact). But any other state on this curve is a transient dynamic state, in which the difference from the line F = gm(z) represents the inertia force that must be generated by acceleration or deceleration of the block of tower mass m(z) above level z of
the top floor of the story.
And the page you reference doesn't seem to be refering to vectors. It is discussing energy, but that's not the same as vectors. Do you know what a vector is? Focre is a vector, it has magnitude and direction. Energy is a scalar, it has only a magnitude.
This is pretty basic stuff.
Totally aside from that, the passage I quoted shows quite clearly that the vectors that you highlighted in the figure are not "energy vectors", they are force vectors, as defined above. You might be able to find some other reference to support your position, but you simply must acknowledge that that figure does not support your position.

No, it is gravitational force that makes things fall down. No one disputes that force is a vector.
Consider a ball rolling down one side of a U-shaped valley, and up the other. Just before it reaches the bottom, it has almost all the kinetic energy it will have, as a result of being accelerated by the force of gravity. If this energy is a vector, with a direction, how then does it use that energy to roll up the other side of the valley? Is there some instantaneous impulse that completely reverses the energy of the ball into "upward energy" just as it reaches/passes the lowest point?

The force of gravity makes stuff fall down. Gravitational energy does not.
I also infer that thermal energy doesn't flow from hot to cold since it has no sense of direction.
Again, this makes no sense. Heat transfers internal energy from one system to another, but it's not a directional transfer. You can't say: the flame heats the pot of water 100 Joules to the left. It's a scalar transfer. Think of it like taking a chunk out of one ball of clay and adding it to another. This transfer of mass is a scalar transfer.

Are you saying that the energy holding Earth in orbit around the sun is a downward force? Or is the gravitational energy caused by the mass of the Earth different from the gravity caused by the Sun? Also remember that "down" is a subjective concept judged from your placement in the system. If you observed the collapse from space, the "direction" would be inward toward the center of the mass, not down.
Also, about the Killtown quote, wouldn't the best thing to do be asking Killtown to clarify what he meant? If he says that he was indeed replying to the intervening posts between his and the first post, then obviously we cannot prove him wrong in any way at all. It wouldn't matter whether or not most people here believe he is a lying scumbag. If he supports your point of view on his context, obviously the quote would have to be removed from the voting. Wouldn't that be better than injecting your own speculation and inference into the situation? (Why does that sound familiar?)

William, we are talking about Killtown here, not R.Mackey. His posting history would indicate that he deserves no benefit of the doubt. This is the same Killtown who won the Stundie last month with "The same way they did the evil faces" post in response to an inquiry as to how the perps wrote 911 in the WTC smoke. I also nominated his beautifully ironic "Saved for prosperity" quote in which he had the audacity to imply that what another poster had just written was soooo far out of touch with reality that he had to save a screenshot of the post[for prosperity]. I've also nominated his "You think those birds are real?" post this month which is sadly gone as the "alternative theories" section is now history.....Killtown emits Stundie material in nearly every thread he posts in. The guy is simply living in another world.
Yes, the "Link to a normal video?" quote is a little nitpicky but I nominated it specifically because of what WWGHA wrote in parenthesis "(not an internet video)".
Anyhow, as for your debunk of the nomination - the "alternate" theories section is now gone so there is no way to review the context. I don't recall Jarroyo's post falling between Killtown's post and WWGHA's post, but that could've been the case, I don't remember. However, it's funny you didn't include WWGHA's reply to Killtown because that's what sealed the nomination for me. He basically asked Killtown how he was "... supposed to provide a link to a non-internet video?" "{Some sarcastic remark}, go watch your Loose Change DVD of the second hit"
So it would appear that the original poster(WWGHA) agrees with myself, Moby, and the six people who voted for the quote that Killtown just had a "blond" moment.

That Griffin mangles scientific language and concepts isn't surprising. It is the least of his errors.
Clearly when anything falls down, all or part can fall sideways. See Jenga for an example. What Griffin is claiming is that it can't fling things as far happened with the WTC. He's insisting that something is fundamentally impossible when all daily experience shows that to be entirely wrong.
That would be bad enough - but one of Griffin's chief arguments that the WTC was demolished is that it didn't fall sideways, like a tree falling in the forest. IOW his two chief arguments are that things shouldn't be hurled sideways, and that everything should be hurled sideways. That makes him special, even in the demanding context of 911 conspiracy theories.

To defend this one hurts me because Griffin is a Theologian and I am at the very least agnostic but here goes...
1. David Ray Griffin's language is not scientific but its intent is clear.
This is actually the exact point I would take issue with.
OK, confession time. I do, occasionally, as does practically every other scientist, from time to time express an idea in rather more scientific, rather than vernacular language, than is necessary. I shouldn't do it, but I'm only human. It's a kind of appeal to one's own authority, a way of implying that I'm right because I'm a scientist and you're not, and it's generally a very bad way of conducting an argument. We're none of us perfect.
What Griffin is trying to do here is exactly that. He could have said "gravity, which acts vertically", and though his overall statement would be a fallacy I would have no particular issue with that part of it; when dealing with relatively much smaller objects falling close to the surface of the Earth, it's so near to correct that the most sensitive instruments would be unable to measure the inaccuracy. But Griffin didn't say that; he said "gravitational energy". His use of the word "energy" in that quote is clearly included to carry the message "I know what I'm talking about because I'm using scientific-sounding words". So he was using BS to make his point, and in doing so he got it wrong.
In short, the essence of a Stundie.
4. Other scientists and engineers express energy and conversions in similar terms.
As we've seen from the example you included, you only think that because you don't understand what they're saying.
Now don't get me wrong, I have no issue with you continuing to hold, and state publicly, the opinions that GPE is a vector, and that Bazant agrees with you. Freedom of speech, after all, would be no freedom at all if it excluded the freedom to state the patently ridiculous. Just be warned that, when you state these opinions to someone who actually knows what they're talking about, you'll start at some point to see a look in their eyes that suggests that they feel their time would be more profitably spent talking with someone different.
I'm getting that exact look in mine right now. Enjoy your thread.

Yes, the "Link to a normal video?" quote is a little nitpicky but I nominated it specifically because of what WWGHA wrote in parenthesis "(not an internet video)".
...
So it would appear that the original poster(WWGHA) agrees with myself, Moby, and the six people who voted for the quote that Killtown just had a "blond" moment.

What's up with all this, William? First you apparently made up an intervening post in a message board that never existed. Then you attributed stuff to a paper that doesn't actually say what you claim. Then you claim not to be able to find the quote one of the other posters cites, even though it's right there on page 4 (page numbers, not PDF page) of the paper and Acrobat Reader has a search function.
Also, the page 14 that you cited does not discuss vector components, it talks about energy and conservation of energy.
You also seem to have force and energy confused or something.
Are you being dishonest with the material you're claiming to use as sources, or are you simply confused?

You can't have a bit torrent of an original video.
In order to get the video in any sort of digital file format, it has to be digitised, and in the process it is compressed - uncompressed DV weighs in at about 1 GB for every 15 seconds of footage.
The original video is magnetic information on a tape. You cannot "link" to that.

In comment to your post, I am being told that energy has no vectoral element so it appears that whilst it is apparent that everyone knows that gravitational energy makes stuff fall down this is simply not so. I also infer that thermal energy doesn't flow from hot to cold since it has no sense of direction.
In case you're wondering, this is exactly why I haven't started that "other thread" I mentioned elsewhere. If you didn't learn in Physics 101* about vector dot products and why kinetic energy is a scalar, then I don't even want to begin trying to explain the torques and cross products that are necessary to discuss rotational motion (ie, "the "tipping" of the top sections of the WTC towers.)
* or for that matter, Physics 102 or Calculus 201** (or whatever the equivalent was at the school you got your engineering degree at)
** or for that matter high school physics - I learned it at the age of 16, along with two hundred and fifty other high-schoolers.

It's on page 5 of the pdf. Search on "inertia force", it was the first hit I got.
This is the full paragraph:
And the page you reference doesn't seem to be refering to vectors. It is discussing energy, but that's not the same as vectors. Do you know what a vector is? Focre is a vector, it has magnitude and direction. Energy is a scalar, it has only a magnitude.
This is pretty basic stuff.
Totally aside from that, the passage I quoted shows quite clearly that the vectors that you highlighted in the figure are not "energy vectors", they are force vectors, as defined above. You might be able to find some other reference to support your position, but you simply must acknowledge that that figure does not support your position.
The figure referred to in your quote is not Figure 2. I would appreciate if you could address figure 2 with your answer.
@ the forum.
I should have made it clearer earlier in the thread but failed to do so which is an oversight on my part. I am NOT trying to prove that energy as defined by classical physics is a vector, as I have said numerous times in the thread already. I am saying that energy has a vectoral quality, specific examples being that gravitational energy can only be released in one direction which is commonly referred to as vertical, that thermal energy only flows from hot to cold.
Energy is scalar as far as the scientific and engineering community is concerned. I will expect the same latitude from you on this as was expected by the forum when I started using engineering terms on here and was slated for using them in the strictest engineering sense.
I am however saying that the nomination for a Stundie was unfounded because there is a lack of understanding of the strictest sense of scientific language in the nominated quote. I fully take on board the rather ridiculous quotes around it but, they weren't nominated were they.

Thank you for your reasoned response, it is very welcome and absolutely in keeping with how I'd like the thread to be.

No, gravity is a force. Gravitational potential energy is the measure of the work done by that force. The force does work, which is measured as energy. The energy is not doing any work, it is a measure of work.

Energy never does any work because it is simply a measure of the work done by something, or the potential work that could be done by something - i.e. the energy stored in a system.
With GPE, the potential energy is the energy that could be released if gravity were allowed to act freely on an object in the absence of a restraint. As I said in my post above, gravity is a force that is doing work, and the energy measures are a measure of the potential energy that is stored in the system, or the kinetic energy that is being released by the system.
You simply equated energy with the element of the system doing the work when it is not. It's a mistake of terms, nothing else.
It's a crude explanation (I am not a physicist), but it should be adequate to clear up the confusion, I hope.
Your metal bar example also shows a misunderstanding of the terms involved. Simply because a situation involves a direction, that doesn't mean that every term involved is also directional. If I'm in a car and I travel at 50 mph to the north, that doesn't mean that my speed is suddenly a vector. Similarly, because the temperature of a steel bar being heated tends towards equilibrium does not mean that the measure of energy involved is expressed as a vector.

If you heat one end of a metal bar, yes the other end will also heat up due to the conductive nature of metal.
And you know what? I guarantee it won't matter how you orient the bar, it will still heat up, doesn't matter if you point the bar up, down, sideways, at an angle between these, anything. Because the heat is not a force being applied in a specific direction.
The air near the surface of the bar will also experience a temperature increase. What do you make of that?

As has been posted before in the thread, he could just as easily have been asking for a link to purchase a "normal" video. As I've stated, that does not even mean that "normal" video even refers to a magnetic media. You are basing the whole argument on your interpretation of what Killtown means in defiance of any actual facts. I am pointing out that whilst alternative interpretations are viable the nominations does not hold.
I only have to show doubt, you have to show absolute proof that you KNOW exactly what Killtown meant.
This is all assumption on the part of the nominee.
You have a link to the thread now. What was Killtown's response to:
1) How the hell do I Link to a video that is not on the internet?? Get out your loose change DVD, i am pretty sure the videos playing in the menu will have a few examples of what i mean.
Was it:
"Whoa wait.... dude, dude - I was asking for a link to purchase some magnetic media or maybe a DVD, ie "normal" videos. I am not so stupid as to ask for a link to a DVD track or a VHS cassette. But I am so stupid as to not be able to use Google to find a link to purchase some "normal" media - so I have to ask you for the link in a manner that makes me look like I'm simply asking to be able to view a normal video with a single mouse click, kinda like I do with internet videos. Sorry for the confusion"
or was it...
"The videos are fake, what else do you need to know?"
I simply did not feel inclined to answer you.
Why is that not surprising, considering this piece of deception:

After that, he send it to the computer. After that he compressed it by an enormous degree to allow fast internet replay. And after that it was posted on YouTube (or GoogleVideo) where it looses even more resolution. And after that someone made a screen capture of the already crappy footage and in most cases blew up the image to focus on the plane.
If you know about videos and graphics, you'll know that every step of the translation of the recording makes the video loose resolution. So the NPTers are basing their "evidence" on already faulty videos.

Energy never does any work because it is simply a measure of the work done by something, or the potential work that could be done by something - i.e. the energy stored in a system.
With GPE, the potential energy is the energy that could be released if gravity were allowed to act freely on an object in the absence of a restraint. As I said in my post above, gravity is a force that is doing work, and the energy measures are a measure of the potential energy that is stored in the system, or the kinetic energy that is being released by the system.
You simply equated energy with the element of the system doing the work when it is not. It's a mistake of terms, nothing else.
It's a crude explanation (I am not a physicist), but it should be adequate to clear up the confusion, I hope.
Your metal bar example also shows a misunderstanding of the terms involved. Simply because a situation involves a direction, that doesn't mean that every term involved is also directional. If I'm in a car and I travel at 50 mph to the north, that doesn't mean that my speed is suddenly a vector. Similarly, because the temperature of a steel bar being heated tends towards equilibrium does not mean that the measure of energy involved is expressed as a vector.

This post occurs a full four posts before WWGHA's post. Also, you have reproduced it here with incredible fidelity. I would in fact say that it would have been impossible for you to reproduce Jarrayo's post with such remarkable fidelity (it is in fact, identical), typos still intact, without actually viewing the thread it comes from.
In fact, it would seem that you DID cut and paste this post directly from the Loose Change Forums. However, you did NOT cut and paste any of the posts that occur between this one and the post for which Killtown was nominated. This includes the one in which WWGHA replies to Killtown.
I would posit that it would be very difficult to miss WWGHA's reply to Killtown, especially as Killtown quotes it in the post he was nominated for.
In fact, Killtown even numbered the paragraphs in WWGHA's post and responded in order of the numbers.
Response by Killtown
1) link to a "normal" video?
2) Example?
Here you have completely failed to mention that Killtown actually quoted WWGHA in his post, numbered his paragraphs and responded accordingly. As I have already established that you must have been on the actual thread to reproduce Jarrayo's post with cut-and-paste fidelity, this means that you have deliberately edited out of this post Killtown's quoting of WWGHA!
That is not some accident or mistake, William. That is deliberately changing the facts and trying to mislead the people here.
Not only that, but in your attempt to reproduce the context of the thread so accurately you ALSO somehow missed the exchange between WWGHA and Killtown that occurs after Killtown's nominated post...
1) How the hell do I Link to a video that is not on the internet?? Get out your loose change DVD, i am pretty sure the videos playing in the menu will have a few examples of what i mean.
2) Look at the pictures in this thread, and the videos they come from! Look at practically any video on the internet of the second airplane hitting the tower.
Does Killtown correct WWGHA and explain that what he really wanted was a bittorrent link to a high quality MPEG4, or a link to a site that sells such videos? No - he simply dismisses all the videos that WWGHA has suggested are fakes...
The videos are fake, what else do you need to know?
So my question is this - why did you leave these out? Could it be because they support the idea that Killtown was asking for a link to a video that is not on the internet?
So you'll have to do better than a halfway there apology for accidentally misleading us.
Apologise for what you actually did. Apologise for deliberately lying to us in an attempt to strengthen your position, by editing the context of the quote from Loose Change and by omitting highly relevant contextual information from the thread in question.
I will not withdraw the ad hominem accusation because to my satisfaction it is proven so you are correct that it is open and shut. If you do not agree then I have no problem with that but I would prefer if you would make the point and let it stand rather than berating me for not doing something completely wrong like apologising for being right.
A question - why is this an ad hominem? How are we attacking the person here? We have ridiculed a request that he made, we have not insulted him as a person.
And another question - if you are so certain that this IS an ad hominem, then why did you deliberately edit the post in question (omitting the WWGHA quote from Killtown's post) and deliberately omit highly relevant contextual information (such as WWGHA post immediately preceding and following Killtown's nominated post)?
Indeed these things are very simple to do for everyone when they have mislead either intentionally or unintentionally.
Well, you have intentionally attempted to mislead the members of the JREF forums and also possible lurkers. An apology for what you actually did would go a long way to restoring your credibility. And a withdrawal of your accusation would go even futher in restoring your credibility.

And it's interesting to note, just after WWGHA asks how to link to a non-internet video, KT posts, but does not correct WWGHA's interpretation of KT's post. So even KT himself agrees with our interpretation!
Busted on "normal videos", busted on "energy vectors". Care to try for a third strike?
I don't know what facts you have based this assertion on because Killtown makes no subsequent comment regarding Amputees "normal" video question. Interestingly, Amputee doesn't press him any further so on the same basis as your argument I will infer that Amputee doesn't agree with his own question.
He only goes on to say that the video files in the suggested source are probably fakes. That is the only fact that can be derived from it.

William, one does not apologise for "accidentally" misleading people if it was in fact deliberate. I see that you have conveniently deleted a large part of my post where I analysed your original claim and demonstrated that you had to have been deliberately lying in your original post.
You complain about my "aggressive" posting manner - was it not you who posted in The Stundies for the sole purpose of stating that you were not participating because you believed them to be ad hominem attacks? Might I remind you that you claimed that "at least two" were ad hominem, a claim you have yet to provide any justification for? Was it not you that began this thread for the sole intention of attacking The Stundies and provoking the other members here?
And was it not you who had to deliberately falsify the context of a quote in order to give your accusation any grounds whatsoever?
Not to mention that you are STILL defending the ridiculous "gravitational energy...which is vertical" quote, despite the fact that it is just outright wrong???
My style may seem aggressive, but that is only because the best defence is a good offence. You began this, and now you are upset because the tables have turned on you?
Tough.
I am politely withdrawing from responding to your posts now as this has stepped way beyond the realms of normality. If you wish to have a more agreeable exchange of views I will then be more than happy to resume corresponding with you.
Translation:
I am not going to reply to you anymore, as you have now repeatedly shown that I had to deliberately lie, falsify context and omit information in order to make my position seem more credible. By saying that I am "politely withdrawing" it seems as though I am taking the moral high ground, and by saying that, "...this has stepped way beyond the realms of normality..." I am subtly suggesting that you are mentally unbalanced. However, I concede that if you promise to stop exposing my intellectual dishonesty and if you stop asking me to apologise for the things that I have obviously done wrong but refuse to admit to then I will talk to you again.
Just a nice move there - running away when you're losing the argument, but trying to frame me as the bad guy. That's not going to make anybody here respect you more.

The force of gravity makes stuff fall down. Gravitational energy does not.
Actually it is the work that gravitational energy does on the mass that makes stuff fall down.
:notm
Contradicting someone is not an argument. If my analysis is wrong I would prefer you to educate me as to how it is wrong.
Okay.
Your statement was: "the work that gravitational energy does on the mass...makes stuff fall down"
This is wrong. Stuff falls down because it's in the gravitational force field of the Earth. The force of gravity is acting on the mass.
The gravitational potential energy of the mass is a result of its position within this force field. GPE is not "acting on" the mass. The mass is storing GPE. The work done on the mass was done by whatever lifted it above the Earth's surface. This work was then stored in the mass as GPE. As the mass falls, no work is being done on the mass. Although the mass's GPE converts to kinetic energy as it falls, no energy is spent--the mass retains all of its energy until it collides with something (in an ideal system, that is--in reality some energy is converted to heat and sound, for instance.)
Think about it. If the Earth had to spend energy attracting things to it, it would run out of energy pretty quickly, wouldn't it?

If I take a bar of steel and increase the thermal energy in one end of it you're saying the thermal energy will not flow to the other end of the bar?
Your example only is (sort of) directional because of the shape you chose to heat and the way you chose to heat it. It's still just a thermal system tending towards equlibrium, though.

Yes, William is currently upset at my having repeatedly called him a liar.
I did a brief summary of what happened that I think is on the bottom of page two.
Basically, he deliberately edited the context of one of the Stundie nominations by omitting relevant information and changing the order of some of the posts.
I don't know why he would do this other than it seems he likes to deliberately rile people up to get his jollies, but this time he's gone too far. If he apologises and withdraws his accusations then all is forgiven. Otherwise I'll just let him run his already ruined credibility further into the ground.

To be fair, IIRC the energy of an object subject to a force field can be defined as the "charge" (mass, if we're speaking of gravity) times the potential function of the field. And the force is defined as the curl of that potential function, again multiplied by the "charge". So there is a way to make a vector quantity from the potential energy, but it's a lot less intuitive than you'd think.
(There are probably better ways of expressing this, but it's after midnight where I'm posting. I tried "the curl of the energy", but that isn't a meaningful physical quantity despite being fairly easily defined mathematically )
This being said, it still doesn't make either the energy, potential or charge anything but scalar quantities.

The word you're looking for is gradient. (The context of this conversation is Newtonian, not GR)
"Curl" comes into play with E&M type fields. (F on a point charge 'e' is perpendicular to the plane formed by the velocity of the point charge 'v' and the electric field 'E' and proportional to the magnitude of the vectors and the sine of the angle between them)

7th April 2007, 05:45 PM
Odd how memory works isn't it?
In the last ten years, I've probably not used the word 'curl' in the E&M / field math sense of the word at all, whereas I've probably used it in other contexts (curly hair, or referencing the linux/unix command line program of the same name) hundreds or thousands of times.
Yet as soon as I saw your post I knew instantly what you were writing about.
For me, it makes Mr. Rea's 'vectorial quality' of Gravitational PE argument a very hard one to swallow.

The figure referred to in your quote is not Figure 2. I would appreciate if you could address figure 2 with your answer.
The terms used in the figures are all the same. There is no place in the text that he specifically addresses the details of Fig. 2, but you'll note:
http://forums.randi.org/attachment.php?attachmentid=6282&d=1175726372
The terms are all consistent with the forces displayed in Figure 2. Note the terms "m(z)g" used in Figure 2. Also note the mathematically equivalent term "gm(z)" term used in the quoted passage:
F = gm(z) represents the inertia force that must be generated by acceleration or deceleration of the block of tower mass m(z) above level z of the top floor of the story.
Also note the use of the term Fc in both figures 2 and figures 3 and 4. Fc is a point on the Y axis, which axis is clearly labelled "Force". There is simply no other reasonable interpretation of Fig. 2, except that it is depicting forces.
For someone who claims to be an engineer to claim otherwise, or to claim that they could not have figured this out themselves, is simply unbelievable. It must be a deliberate attempt to mislead those who don't know how to understand such figures.
And that makes it another lie.
So, I concur: William Rea is a lying liar who lies. He lied about the context of the KT quote, and now he's lying about what the linked paper is showing.
Mr. Rea, you are a stinking liar!

I can't speak for other states, although I imagine they don't depart significantly from this system, but in Arizona the first test is the Engineer In Training (EIT) Exam, which tests general engineering principles along with physics, math, chemistry, etc (all the foundational sciences). After accumulating enough work experience under the supervision of a Registered Professional Engineer you get to take one (or in the case of structural, two) more test called (strangely enough) the Professional Engineer (PE) Exam, which is discipline-specific (Arizona recognizes something like 27 different disciplines). The first exam is widely held to be the more difficult one, and is (according to what I've been told) the largest hurdle for non-degreed engineers to overcome.
I know several PEs who don't have engineering degrees. They have a different perspective on things, to say the least (especially the one with a degree in journalism) but they are still conversant with general science.

Heh. Yeah.
What makes me most suspect of his claim that he's an engineer was when he "corrected" my statement: "The force of gravity makes stuff fall down. Gravitational energy does not."
with: "Actually it is the work that gravitational energy does on the mass that makes stuff fall down."
I suppose it's possible that he lied both by claiming to be an engineer and by deliberately misrepresenting a diagram. I get the feeling, though, that he truly doesn't understand what energy and force mean in Newtonian terms.

Well, energy and motion Are out of the purview of Civil Engineers...They go to great lengths to make sure things don't move. So I guess it is possible that he hasn't dealt with them in many years.
Not likely, though, that even an engineer who has moved into sales or something would forget something so basic.
But we must remember, 1/2 of all engineers (like MD's) graduated in the bottom 1/2 of their class.

That's one of the ways they try to "divide and conquer". By using two examples from different disciplines, he hopes that, the engineers will say, "He's wrong about the forces thing, but the linguistic analysis seems plausilbe", while the linguists will conclude the opposite. That's why we need all the different JREFer types to work together - we can show why all his examples are flawed.

Then you claim not to be able to find the quote one of the other posters cites, even though it's right there on page 4 (page numbers, not PDF page) of the paper and Acrobat Reader has a search function.
Also, the page 14 that you cited does not discuss vector components, it talks about energy and conservation of energy.
You also seem to have force and energy confused or something.
Are you being dishonest with the material you're claiming to use as sources, or are you simply confused?
With respect, without links or more detail I simply do not understand what you are trying to say here. Would you clarfiy a little more for me please.
William Rea
10th April 2007, 09:32 AM
No, gravity is a force. Gravitational potential energy is the measure of the work done by that force. The force does work, which is measured as energy. The energy is not doing any work, it is a measure of work.
You might use the words interchangeably, but that doesn't make you right.
The force is simply a means of expressing the energy flow dynamically, it is not the primary factor in energy problems as you imply. I can describe the transfer of energy from PE to KE in energy terms simply by using conservation of energy without mentioning a single force.
With respect, I do not interchange them, I use them in context.

The difference between a scalar and a vector is:
a scalar has magnitude
a vector has magnitude and directionTo say that energy (a scalar) "has a sense of direction", then, is to say that it is not a scalar at all, but rather a vector.
And I have shown you that energy does not have direction, as have others.

B. I haven't claimed that energy isn't scalar, I simply asserted that it has a sense of direction like a vector and no one as yet has shown me that it doesn't.
Consider the following situation.
A spherical shell of material is placed somewhere in interstellar space, sufficiently far from any other masses that the effect of gravity other than its own may be considered negligible. The object has mass, and all parts of it are therefore attracted towards its centre of mass. If the material is shattered into small particles, all will fall into the centre, converting their gravitational potential energy into kinetic energy as they fall. The entire system has spherical symmetry.
What is the direction of the gravitational potential energy?

Your metal bar example also shows a misunderstanding of the terms involved. Simply because a situation involves a direction, that doesn't mean that every term involved is also directional. If I'm in a car and I travel at 50 mph to the north, that doesn't mean that my speed is suddenly a vector. Similarly, because the temperature of a steel bar being heated tends towards equilibrium does not mean that the measure of energy involved is expressed as a vector.
I appreciate that the tone of your post is not adversarial but with respect, if you are travelling 50mph North that is exactly a vector. I think what you are trying to say is that if you are travelling 50mph then that is a scalar quantity, and I agree with that. However, I don't know of any use that that scalar quantity has to Engineers, without the direction it is meaningless. Just like saying I have 2MJ of Energy without understanding how to make it do Work by employing a device that converts the fact that if falls down or flows from hot to cold.
Likewise, you can say energy is scalar and be absolutely right by the text book answer but denying that it has a vectoral quality in that it doesn't "flow" from up to down or hot to cold (in laymen's terms) is impractical.

As has been posted before in the thread, he could just as easily have been asking for a link to purchase a "normal" video. As I've stated, that does not even mean that "normal" video even refers to a magnetic media.
Why are we still even having this discussion, William? This is open and shut - WWGHA defines a 'normal video' as 'not an internet video'. Killtown then asks for a link to a video that is, by definition, not on the internet!
To be fair to killtown (woah! I need to take a shower, now), I think he was saying "Huh ? A link to a "normal" video ? Why, that's not possible." Of course. That's still a stupid thing to post, but it's not the same level of stupid, assuming I'm correct.

You're still confused about the terms. In the example I posted, the direction is irrelevant to the speed. The speed is 50mph. The velocity is a vector quantity consisting of the 50mph and the direction. In rough terms, you could say the velocity is 50mph to the north.
If I suddenly started going 50mph to the south, my speed would be the same, but my velocity would be different.
It's not about having "vector qualities" or anything, there are words for things like "speed plus direction." In that case, it's "velocity."
Likewise, you can say energy is scalar and be absolutely right by the text book answer but denying that it has a vectoral quality in that it doesn't "flow" from up to down or hot to cold (in laymen's terms) is impractical.
You misunderstand energy. Energy moving towards equillibrium does not give it a direction that can be quantified as a vector. Another poster mentioned the bar's orientation changing, and asked if this would affect the direction of energy transfer.
Vectors need a precise, mathematically defined direction. You can't simply say "it moves in a direction, therefore it is a vector!" No, that doesn't make energy a vector, or give it a "vectoral quality" (which is a meaningless term, by the way).
By the way, stating something has a "vectoral component" or whatever is equivalent to saying it's a vector, just in a more weasel-esque way.
The force is simply a means of expressing the energy flow dynamically, it is not the primary factor in energy problems as you imply. I can describe the transfer of energy from PE to KE in energy terms simply by using conservation of energy without mentioning a single force.
With respect, I do not interchange them, I use them in context.
I didn't say anything about PE and KE transfer, I said you are mixing force and energy. Those aren't terms that describe force, they describe energy. Force is work done on an object, energy is the amount of work something can do. A term like PE or KE addresses the total work present in an aspect of a system. That energy can be released in different forms.
I implied no such thing.
I had a little chuckle at that one. You used my joke about being a civil engineer except when I get mad as a claim on my part that I was a Civil Engineer. :)

Engineers use speed all the time--when they're doing energy calculations. In KE = ½*m*v2, you can ignore the directional component of the velocity v, treating it as a scalar speed.
Likewise, you can say energy is scalar and be absolutely right by the text book answer but denying that it has a vectoral quality in that it doesn't "flow" from up to down or hot to cold (in laymen's terms) is impractical.

If I may elaborate on your model, assuming you are meaning the pole is a simple cantilever then it will bend around an internal neutral axis. On one side of the neutral axis there is tension and on the other is compression. Both involve storage of elastic strain energy at a microstructural level in the pole.
The PE will convert to KE in the direction that returns the pole to equilibrium.

Interesting, can I just clarify that the sphere is a closed system and has spontaneously shattered with no energy or work entering the system boundaries? Can the sphere also be considered to be neutral in terms of internal stresses and any pressure differences between the inside volume and outside?

The PE will convert to KE in the direction that returns the pole to equilibrium.
Let's complete the scenario, then. Picture this:
The bent pole, as you said, stores PE in the form of elastic energy through both compression and tension (which are themselves scalar, BTW). [edit: strike-through--I was thinking of pressure, but we're talking stress]
The tension is directed "inward" toward the center of the pole along the convex side of the arc, while the compression is directed "outward" toward the ends of the pole along the concave side of the arc.
When the pole is released, the tension "pulls in" and the compression "pushes out" as PE converts to KE.
But the potential for this system to do work is in the force at the free end of the pole, perpendicular to the pole.
In what sense, practical, theoretical, or otherwise, does it make sense to assign a "vectoral quality" to this energy?

Contrary to your opinion, I wasn't actually attacking you. I was pointing out that your understanding of physics does not appear to coincide with your profession, and I would appreciate some kind of reconcilliation of those conflicting pieces of information.
As you have lied about other matters in this thread (or, at the least, been intellectually dishonest... if I am being charitable), I don't place a very high value on your unsupported word at this point.
I also did not say that you were, in fact, a hamburger flipping engineer, I was merely pointing out that there are other uses of the word "engineer" (the "railroad engineer" example was a genuine one, the other was a joke) that a dishonest person could play on to legitimately claim to be "an engineer," without being the sort of engineer that is at all relevant to the matter at hand.

It is not stress energy, it is internal strain energy.
The PE is stored in the internal strain of the microstructure of the pole very much as it is in a spring. The work done has created a new equilibrium state in the strained pole in which the work input is equal to the internal strain energy. You don't say how the pole was bent but assuming it was by a human then the energy trail for the human input is chemical energy (food intake) to kinetic energy (muscle action) to potential energy (internal strain energy).
I know where you are going with the force at the end of the tip but in energy terms until the strained pole is released it is in a new state of energy equilibrium.

Face to face I'm sure I would have been able to successfully signal the joking nature.

Rather than attacking I am now trying to either ask for clarification if I am unsure or just responding neutrally to say I am not interested in hostility.
I have questioned myself several times about whether I am very effective at communicating on forums because I seem to attract so much hostility that I feel is unwarranted. I have read back several times to check this and have come to the conclusion that it deosn't matter what I say to some people on here I will only get hostility back.

I've considered the somewhat frightening possibility that he was being truthful about being an engineer AND was being indeliberately muddle-headed about force vs. energy.
There is, after all, at least one practicing engineer (http://www.google.com/search?hl=en&lr=&safe=off&rls=GGLG%2CGGLG%3A2005-43%2CGGLG%3Aen&as_qdr=all&q=%22william+rea%22+%22avondale+house%22+OR+%22an+ bord%22&btnG=Search) by that name. This one works on relatively small-scale projects, and I suppose it's possible that certain basic physics concepts don't play all that big of a role in his day-to-day practical work. I suppose it's also possible that he made a career in engineering without ever having really understood some of those basic concepts. He may get by just fine merely by being familiar with local building codes.

The terms used in the figures are all the same. There is no place in the text that he specifically addresses the details of Fig. 2, but you'll note:
http://forums.randi.org/attachment.php?attachmentid=6282&d=1175726372
The terms are all consistent with the forces displayed in Figure 2. Note the terms "m(z)g" used in Figure 2. Also note the mathematically equivalent term "gm(z)" term used in the quoted passage:
Also note the use of the term Fc in both figures 2 and figures 3 and 4. Fc is a point on the Y axis, which axis is clearly labelled "Force". There is simply no other reasonable interpretation of Fig. 2, except that it is depicting forces.
For someone who claims to be an engineer to claim otherwise, or to claim that they could not have figured this out themselves, is simply unbelievable. It must be a deliberate attempt to mislead those who don't know how to understand such figures.
And that makes it another lie.
So, I concur: William Rea is a lying liar who lies. He lied about the context of the KT quote, and now he's lying about what the linked paper is showing.
Mr. Rea, you are a stinking liar!

Indeed, although once again I have been accused of malicious intent I felt that the universality of Conservation of Energy could be broadened out by introducing thermodynamic energy to show energy flow. As energy is a universal concept in all branches of engineering and science I didn't feel that it was a major leap or even an obfuscation. Maybe, I was wrong.
I now understand what you meant by momentum, thanks for the clarification.
I get the impression that it is not being comprehended that all of these theoretical situations can be analysed purely in terms of Conservation of Energy without using forces. Forces have uses but they are not essential unless you want to know the dynamics.
I still contend that whatever euphemism you use gradient or vertical there is an instinctively directional or vectorial nature to energy.

To be fair to killtown (woah! I need to take a shower, now), I think he was saying "Huh ? A link to a "normal" video ? Why, that's not possible." Of course. That's still a stupid thing to post, but it's not the same level of stupid, assuming I'm correct.
I would suggest that you're probably reading more into the context than is necessary.
Killtown's quote was unaccompanied by any non-verbal cue (an emoticon, for example) to suggest he was either joking or ridiculing WWGHA's post. On top of that, WWGHA had never suggested that Killtown try downloading said file from the net - the topic of linking to a "normal" video (a word which WWGHA also put inside quotation marks, IIRC) was raised by Killtown, in an interrogative statement that had no defining traits with which to recognise it as intentional sarcasm or irony.
On top of this, the posts following Killtown's nominated post give even more context - WWGHA actually picks up on what Killtown has said and questions as to how he could possibly post a link to a non-internet video (which is what he had previously defined a "normal" video as being). Killtown's response was not to explain his statement further, but to ignore this comment and simply decry that the videos are all faked anyway.
This quick changing of topic away from a mistake that has been pointed out is known behaviour for Killtown to engage in when someone has pointed out a very silly or obvious mistake he has made. What Killtown is not well known for is letting people who deliberately or unintentionally misinterpret his words get away unscathed.
In other words, the most likely interpretation of this for a person who is NOT known to the person doing the analysis is that they said something very silly by asking for a link to an internet video. That we know that this is likely behaviour for the participant in question simply strengthens this interpretation - it is not, however the basis for it.

William, you appear to have completely ignored my analysis here. Admittedly, this could be because I pointed out your complete intellectual dishonestly and requested an apology, but I suppose it is possible you just missed it on your way through.
I would like you to address this, and if you cannot, I would appreciate an apology both for the fact you deliberately tried to lie about the context of the quote and a retraction of your accusation that this is an ad hominem.
-------------------------------------------------------------------------
I would then like you to answer this question:
Is gravitational potential energy a vector?
All this requires is a yes / no answer.
If your answer is yes, then you will have to explain to us all how energy can be a vector, and how you came to this discovery that will overturn most of what we know about Newtonian physics.
If your answer is no, then I would appreciate a retraction of your accusation that, "...gravitational energy, which is vertical..." is an ad hominem attack.
-------------------------------------------------------------------------
Then, as you claimed to have found, "...at least two..." ad hominem attacks in the March Stundie Finalists, I would appreciate it if you could please continue to point out ad hominem attacks that are present there.
I imagine that I am not the only one who would like to see these things addressed, but I thought I'd break it down into sections for you for ease of reference.

I'm sorry that you felt compelled to join the detractors instead of engaging with me. I only asked you to address your comments to figure 2 and you berated me for lying about it in a baseless manner.
I did "engage" you, and you responded by misrepresenting the source you claimed supported your assertions, and then implied that I was manufacturing and/or misinterpreting the quotes I cited. The fact that you chose to cloak your insinuations in superficially polite language does not change what you did. In fact, in my opinion, that makes it worse.
And I wasn't "compelled" to join your detractors. They made good points, which I agreed with, and which confirmed my own impressions of you. And to call the accuations of you being a liar "baseless" shows you either to still be lying, or to being willfully blind to the several analyses of your claims that clearly demonstrated your lies.
Your post was extremely aggressive and with repect, I found very little honorable intent on your side in it. Since you find me so disagreeable I suggest we do not exchange any further posts.
Of coure a liar finds very little honour in others who point out his lies. That's just par for the course. Yet another example of you trying to cloak a disgusting attitude with superficial politeness. Rather than simpering about "aggressive" attitudes, why not try admitting your lies, and asking forgiveness? Why not try addressing the aforementioned analyses of your lies, and demonstrating how they might not be lies?
Why not? Because you know we're right.
And we may not "exchange" posts, but I'll be around to point out any other lies of yours I see. Because, with all due respect to Douglas Adams, when you get right down to it, the one thing I really can't stand is a liar.

This is, I think, the thing I find most bizarre about this thread, notwithstanding William's attempts to defend the indefensible position that energy has a vectoral quality; the completely inappropriate use of the term ad hominem. The definition of argumentum ad hominem is an attempt to discredit someone's arguments by reference to some unrelated quality of the person making them. In the case of the Griffin quote I nominated, I made no comment whatsoever about Griffin himself, and none of the discussion since has commented on anything about Griffin that is not directly related to the five words under discussion - how could any of this be further from an argumentum ad hominem?
The nearest thing to an ad hominem in this thread, in fact, was William's initial statement of his reluctance to defend the position taken by a theologian; Griffin being a theologian is irrelevant to whether or not his statements about physics are fallacious. Although appended to an expression of support, that initial statement had much in common with an ad hominem attack on Griffin - more, in any case, than energy has in common with a vector.

Interesting, can I just clarify that the sphere is a closed system and has spontaneously shattered with no energy or work entering the system boundaries? Can the sphere also be considered to be neutral in terms of internal stresses and any pressure differences between the inside volume and outside?
Sorry, missed that post for a while. (1) isn't relevant, I'm talking about the GPE of the static system; it's not physically realistic but you can assume some mechanism that involves negligible energy if it helps. (2), yes.

Dammit!!! Why did you have to give away my surprise ending??? :mad:
I'm not kidding about this actually...I've been waiting for William to make another claim just so I could spring this one on him.
See, I figured the discussions re his first two claims had been so well examined and shown to be bunk that bringing this up would just continue discussion on topics that had really reached the end of the line (I've summarised what I, and most people are expecting from you in regards to the first two accusations in a post just above this, William).
Waiting for him to bring up a new accusation, my first question was simply going to be: "And how is that an ad hominem?"
I probably should have done that right when this all started, but I so quickly got involved in debating the original grounds for inclusion in the finals that by the time he started this new thread I didn't want to have the appearance of ignoring his arguments by presenting this issue.
I suppose I can still ask that question when he has a third attempt, but it's lost its surprise value now. Dangit!

It would, however, be wrong to categorise William as wrong or a liar simply because the majority of people here think so. That right there is an appeal to popularity.

11th April 2007, 10:57 AM
A normal person might respond in that way, but remember we're talking about Killtown. Asking for an internet link to a non internet video is precisely the sort of thing I would expect Killtown to do.
Which is why I'm not assuming anything. I'm just pointing out that this short sentence by Killclown might actually not have been AS stupid as we thought. In fact, I've never read it that way, since it was Stundied.
Killtown's quote was unaccompanied by any non-verbal cue (an emoticon, for example) to suggest he was either joking or ridiculing WWGHA's post. On top of that, WWGHA had never suggested that Killtown try downloading said file from the net - the topic of linking to a "normal" video (a word which WWGHA also put inside quotation marks, IIRC) was raised by Killtown, in an interrogative statement that had no defining traits with which to recognise it as intentional sarcasm or irony.
That seems irrelevant :
Hypothetical poster: "If you check a NORMAL video (not an internet compression), Belz..., you'll see that your interpretation makes no sense."
Belz...: "Link to a "normal" video ? How would you want me to do that ?"
H.P.: "You can WALK, Belz..."
Leaving out the last part of my hypothetical reply would not be unexpected from an internet poster. I find it hard to believe that even Killtown would want a link to something that, by definition, cannot have one.

Leaving out the last part of my hypothetical reply would not be unexpected from an internet poster. I find it hard to believe that even Killtown would want a link to something that, by definition, cannot have one.
Were the exchange between Killtown and WWGHA to resemble what you have posted between your hypothetical poster and yourself you would have a point.
But your exchange and the exchange that actually took place are quite different.
Most importantly, Killtown's response was not, "Link to a "normal" video ? How would you want me to do that ?" It was simply, "Link to a "normal" video?" Given that the other part of that post was simply, "Example?" it would be reasonable to assume that both parts of the post were requests. There is nothing in Killtown's post that suggests his "Link to a "normal" video?" remark is anything other than a request for a link.
Next most importantly, your hypothetical poster's reply to your statement is an unnecessary addition, as there WAS in fact a follow-up to Killtown's post. WWGHA expressed confusion at Killtown's apparent request for a link to a non-internet video. Killtown did not do anything to clarify his nominated post. There was no ridiculing of WWGHA for his ridiculous suggestion that Killtown was asking for a link to a non-internet video or any other sort of clarification.
Yes, other interpretations of Killtown's post are possible. It is entirely within the realms of possibility that everything Killtown has ever posted has simply been part of a huge practical joke and that he's having a good laugh at us taking him and his ideas as though he is being serious.
But the interpretation of Killtown's post that is far and away the most probable interpretation, in fact to a degree that I would suggest gives any other interpretation only a very, very remote probability of being correct, is that Killtown was asking for a link to a video that is by definition not on the internet.
I really don't understand why this debate is even still taking place. WWGHA defined a "normal" video as a non-internet video. Killtown then asked for a link to a non-internet video. This is BASIC linguistic analysis...

I haven't argued the case for the original statement from a position of ignorance as you would like to think but as a Devil's Advocate.
I am trained in and used to the Newton-centric world view where Energy is essentially an abstract concept and mechanistic Forces acting upon Masses are the key outputs required.
From the opposite view point Energy is not abstract, it is tangible. It is as easy to conceptualise from an energetic point of view where forces are an incidental result of energy doing work. The direction of the resulting forces are aligned with how Energy has the ability to carry out this Work. Can you demonstrate how Gravitational Potential Energy working on a free body will spontaneously create a force that acts directly away from the two centres of mass? Of course the person who questioned the concept of vertical knew that working with Potential Energy requires a reference framework, one of the three axes that are commonly chosen to simplify the mathematics is commonly referred to as vertical.
Energy is a universal concept across many academic disciplines, doing work on a closed system will raise its Energy just as getting a closed system to do work will lower its Energy. This is true for Thermodynamics and it seems to be the general opinion that I introduced this concept to obfuscate but it was merely to show how Energy as a universal concept works.
The need for energy to move towards equilibrium makes the Potential Energy of an object Work on its mass to lower its Energy. That is the direction, the driving force. Mechanical systems are not immune from the law of Conservation of Energy so just as Energy behaves Thermodynamically so it does Mechanically.
This is why the Stundie nomination was not deserved.
I have tried to explain this in as close to layman's terms as I can so if it is not scientifically rigorous enough for you then I invite you to ask questions for further clarification rather than berate me for straying from text book science.
This is my last post on this particular nomination except where people require clarification. It has been sad for me that the journey could not have been more pleasant but it told me a lot about the forum.

This Killtown ‘debunking’ reminded me of what I always disliked about English Lit, namely the subjective interpretation of of somebody’s writing. If you want to know what an author really meant, just ask them! Sitting around guessing their intention doesn’t really get the debate anywhere; people can just defend whatever piece of guesswork best fits their own biases. You could just ask Killtown directly, and agree or disagree to take his answer, if one were forthcoming, as the final word.
Debunking a Stundie (or nominating one) on the basis of what you think somebody meant, from their somewhat ambiguous phrase, can lead to an unresolvable debate about meanings and intentions.
It reminded me of this exchange between Lisa Simpson and Amy Tan:
Lisa:
Miss Tan, I loved The Joy Luck Club. You really showed me how the mother-daughter bond could survive adversity.
Amy Tan:
No, no, that's not what I meant at all! I can't believe how wrong you got it.
Just sit down, I'm embarrassed for both of us.
My verdict, for what it's worth:
WR didn't succesfully debunk the Killtown nomination, for reasons stated above. He can have only as much certainty of what was meant by Killtown as any of the rest of us. I think that particular nomination was too much of an 'inside joke' than anything else; a new reader of this forum may not have any understanding of what that quote represented.

This is gibberish. It makes no more sense from a layman's viewpoint than it does from a physicist's.
This is why the Stundie nomination was not deserved.
I'm not sure what you think the "Stundies" are, but Griffin's statement was wrong, and he used that wrong statement to wrongly question the behavior of the collapsing WTC towers--he made a wrong statement in an area that was so clearly out of his league, and with such authority, that the person who nominated it thought we'd get a chuckle from it.

Layman's terms still have to be accurate. When we explain something in layman's terms, it doesn't mean we explain something according to a layman's misconceptions, it means we explain something that a layman finds counterintuitive and/or complex using descriptive examples and analogies, in everyday, familiar language. But we do so while remaining accurate, the goal being to give the layman an accurate understanding of the concept.

You can be as arrogant as you want, but if you're going to link to not one but three of my posts, you can sure-shooting bet I'm going to respond.
I those were the only definitions of The Stundie you could find I'm a bit shocked - it has been pointed out multiple times that they are a still evolving concept. I find it very interesting that you posted (with your third link) only two of the trial rules for The Stundie when on the very first page of that thread I clearly list a number of trial rules for April...
Let me point out some things you may have missed though...
... they deal directly with stupid things said by conspiracy theorists...
So the nominations deal with the things that are said, not the people who said them. This has been broadened to include debunkers as well, as can be evidenced by the March Finalists.
Stundie nominations should 'stand alone'. Do not over-embellish introductions, but do provide comments. Do not use any blatant ad hominem attacks.
In other words, nominations must be about the actual thing being said and not the poster. Nominations must not even be accompanied by ad hominem comments.
From the third link again...
Make sure that nominations are being posted because of the arguments or claims being put forward and not simply because you dislike the person.
And in regards to any ad hominem attacks that are posted...
Be advised too that even if you do post such nominations here, they won't make it through to the final vote.
As for your second link - I don't think that posting the tongue-in-cheek in-joke ridden Stundie speech is entirely convincing as an argument. After all, it is a work of humor, not a strict definition of The Stundies.
Now, once again you seem to have missed my post from above. I'll repost it here:

Is gravitational potential energy a vector?
All this requires is a yes / no answer.
If your answer is yes, then you will have to explain to us all how energy can be a vector, and how you came to this discovery that will overturn most of what we know about Newtonian physics.
If your answer is no, then I would appreciate a retraction of your accusation that, "...gravitational energy, which is vertical..." is an ad hominem attack.

1. I have never claimed to be a Civil Engineer. I have no idea why I would need to be uniquely qualified as a Civil Engineer to understand this topic.
I stand corrected. I used the search engine for posts by you with "engineer" and too quickly latched on to your 'uncivil engineer' joke post. Nevertheless, the basic point stands. I have a difficult time reconciling the basic knowledge required to be any kind of engineer with the content of some of your posts.
A. I have not modified my position once.
Kinetic Energy = 0.5mv^2. Velocity has speed and direction.
I would say in this sense that energy has a direction
Reference post #88 above. If Gravitational Energy (remember the nomination said Gravitational Energy NOT Energy) is scalar then why is it proportional to a vectoral quantity?
I read these posts as you claiming that energy is a vector with both magnitude and direction.
I am saying that energy has a vectoral quality, specific examples being that gravitational energy can only be released in one direction which is commonly referred to as vertical, that thermal energy only flows from hot to cold.
Energy is scalar as far as the scientific and engineering community is concerned.
And I read this as backing off to saying "vectoral quality."
If I'm interpreting your posts incorrectly and you meant all along this "vectoral quality," my general point still stands. I can't reconcile the claim of being an engineer with this "energy has a directonal sense" notion.
B. I haven't claimed that energy isn't scalar, I simply asserted that it has a sense of direction like a vector and no one as yet has shown me that it doesn't.
1) Consider a wagon on a slope. If GPE "points down," and "releases vertically" why will the wagon move diagonally down the slope? There is no "horizontal component" to the GPE. Also, how does this "vertical energy" get converted into the rotational kinetic energy of the wheels? And which direction "vectorally" is that rotational KE pointing? For energy to have a "vectoral quality" and also be conserved, you'd better make those directions add up on both sides of the equation!
2) I have a AA battery on my desk. It has roughly 1000 Joules (http://forums.randi.org/http://www.evworld.com/library/energy_numbers.pdf) of chemical potential energy in it which will release when the battery is connected to an electrical circuit. In which direction is that chemical PE pointing?
3) There's an atom which is in an excited state; Namely one of its outermost electrons is in a "higher orbit" (The Bohr model is just fine here) than the ground state. In which direction is this excitation energy pointed?
4) There's a crate containing a ton of TNT explosives sitting in a field. In which direction is the chemical potential energy of the explosives pointing?
5) And while we're at it: Using conservation of energy, and without using forces forces, solve the one-dimensional perfectly elastic (no loss of energy) collision between two equal masses;
(M) --> V1 V2<-- (M)
Namely; solve for the velocity of one of the masses after the collision in terms of the mass M and the initial velocities V1 and V2.
In answer to your problem I would simplify it by taking a cross sectional view of the disc showing the direction of transfer of heat energy from the inner to outer edge.
In reference to my heating the center of a disc example, is this your claim? (I hope the ASCII art works out)
___________________
|_____<--*-->_____|
That the thermal energy in this case, which will move radially, has a "vectoral quality?" A vector cannot point in every direction (in the plane of the disk) at the same time. Alternately, if one integrates the sum of the "differential vectors" over all angles, guess what? The directions cancel out, and the thermal energy's "vectoral quality" sums to zero mangnitude.
C. I need you to clarify what you mean when you say I have mixed "work" and "energy" because I do not understand how you then extrapolate this to imply my education must be sub-standard in some way.
Actually it is the work that gravitational energy does on the mass that makes stuff fall down.
This makes no sense at all if one is using the terms "work" and "energy" in their scientific sense.
I am still willing to go through that excercise of modelling the WTC collapses, but not if we're going to have to argue like this over basic concepts and terminology.

Which scientific sense do you wish to use?
How about (http://en.wikipedia.org/wiki/Mechanical_work):
In physics, mechanical work is the amount of energy transferred by a force. Like energy, it is a scalar quantity, with SI units of joules. Heat conduction is not considered to be a form of work, since there is no macroscopically measurable force, only microscopic forces occurring in atomic collisions. In the 1830s, the French mathematician Gaspard-Gustave Coriolis coined the term work for the product of force and distance.[1]
Positive and negative signs of work indicate whether the object exerting the force is transferring energy to some other object, or receiving it. A baseball pitcher, for example, does positive work on the ball, but the catcher does negative work on it. Work can be zero even when there is a force. The centripetal force in uniform circular motion, for example, does zero work because the kinetic energy of the moving object doesn't change. Likewise, when a book sits on a table, the table does no work on the book, because no energy is transferred into or out of the book.
When the force is constant and along the same line as the motion, the work can be calculated by multiplying the force by the distance, W = Fd (letting both F and d have positive or negative signs, according to the coordinate system chosen). When the force does not lie along the same line as the motion, this can be generalized to the scalar product of force and displacement vectors.

Where I have already addressed this issue.
I had rather hoped that someone would have spotted this by now. Since it has not been taken on board I guess I will have to be more direct. The assumption about Griffin's statement is that there is only a Newton-centric (Physics) concept of Energy based upon Work which is considered as a Force acting over a Distance. In this definition Energy is not a tangible "thing" but only exists when a Force does Work on a Mass.
In fact Energy has a direction which is towards equilibrium.
I have no problem with viewing Work as being the result of humans using mechanisms to exploit this "directionality" of energy. Heat Engines exploit the flow of thermal energy through a working substance between a Hot and Cold (High and Low Energy) gradient. Interestingly the Efficiency of Heat Engines is measured in terms of this gradient.
I plead guilty to the charge of being vague and playing around with the Physics in a Devil's Advocate manner, as I said before, it has told me a lot about the forum.
I will take the liberty of addressing your scenario's one by one so as not to get in a confused mess, which may mean you have to wait a day or two for them.

1) Consider a wagon on a slope. If GPE "points down," and "releases vertically" why will the wagon move diagonally down the slope? There is no "horizontal component" to the GPE. Also, how does this "vertical energy" get converted into the rotational kinetic energy of the wheels? And which direction "vectorally" is that rotational KE pointing? For energy to have a "vectoral quality" and also be conserved, you'd better make those directions add up on both sides of the equation!
An interesting scenario and one which I expected to arise because of the horizontal element.
For convenience I will initially start by making the Closed System around the wagon. We can develop it from there but I would like to start basic if you have no objections. I will also assume that the datum is what we would commonly term the bottom of the hill.
Energetically (assuming there are neglegible frictional losses) the slope of the hill is meaningless and would be considered simply as a mechanism to convert the Energy from GPE into a useful direction to use the Kinetic Energy output for whatever reason we choose. This would be like any other mechanical construct that involves a wedge i.e. a screw thread.
The horizontal element therefore is a red herring.
The GPE in the Closed System will work on the mass converting to Kinetic Energy just as it would if falling directly.
Because of the slope the Power Output will reduce (the reverse effect of using the slope to enable us to lift the wagon more effectively).

But in the real world, energy is lost through friction. Explain the conversion of the wagon's KE to heat/sound in terms of its "vectoral quality".

I am going to wade into this vectoral energy conversation late, having seen the other thread, and having read most of this thread. Please ignore me if I'm repeating myself or others.
First, let me start with the definition of energy. It's scalar. Everyone should agree on that. Similarly, all the physical laws of nature involving energy are defined using a scalar form of energy.
While it can be said that gravitational energy can only be "released" one way, that's a highly imprecise language compared with standard physics. There is no mathematical description for "energy release" along a vector. Similarly, any such quantity as "vectoral energy" or any such equations defining the actions of "vectoral energy" very much differ what what is known as energy.
In other words, on a semantic level alone, the concept of "vectorial energy" isn't energy. This alone doesn't make it meaningless or useless, just different. And different implies that none of the laws relating to energy apply to vectoral energy.
Also, I'd like to clear up some misconceptions from William from early on (I only read his posts, so if someone else corrected him, I might have missed it).
Are you saying gravitational energy has no directional sense?
Potential or Gravitational energy = mgh where g = acceleration. Acceleration is change in Velocity with time. Change in velocity can occur either by change in speed or direction. Gravitational Energy is derived from forces occuring between the centres of mass of two objects, that is a unidirectional relationship.
This is not technically correct and leads to a slightly wrong interpretation. In the equation mgh, g and h are not vectors, but magnitudes. The equation is technically m*||g||*||h||. I use bold for vectors and non-bold for scalars.
More accurately,
GPE = m(G dot H) where the acceleration due to gravity and the "height" are vectors. The dot product of two vectors is always a scalar. This equation demonstrates that there is no direction in the GPE. Consequently, the comment about acceleration also being a change in direction is true but irrelevant in this case. The dot product projects the acceleration due to gravity to a specific vector (no idea if you followed that... in other words... because G and H are gaurenteed to be measured along the same line, the projection of one onto the other is equal to the magnitudes (no direction) multiplied).
No aspect of the vectors involved (acceleration or displacement) "survives" the dot product.
Kinetic Energy = 0.5mv^2. Velocity has speed and direction.
Similarly, the equation for KE contains the term 'v' but that it is -not- a velocity vector. Kinetic energy's full equation (vectors bolded) is 1/2 (V dot V), which simplifies to 1/2 ||V||*||V|| because an identical vector always points in the same direction as itself. The dot product results in a scalar quantity, demonstrating the scalar nature of energy.
I would say in this sense that energy has a direction and is therefore able to be represented vectorally.However, in that sense (the mathematical one, that is), the exact opposite is true. The directions "cancel", for lack of a better term, and the final unit has no direction.
In our world view Potential or Graviatational energy is described vectorally as acting vertically as opposed to horizontally.But gravitational energy doesn't act in any direction as demonstrated above. If you have some alternate definition of gravitational energy which preserves direction, I'd like to see it. However, your new "vectoral energy" isn't the same as gravitational potential energy, and all the laws of physics that normal GPE applies to likely won't apply to your new vectoral version.
That is not to say there isn't some physical significance to a vector-energy. It certainly has some "meaning". The only question is what equations can you use to determine it's behavior. My suspicion is that such a quantity is fairly useless, but I might be wrong. The error comes when you try to apply normal physics of energy to "vectoral energy" as the very-original-post did.

This is all correct. Although you did neglect to mention that we also need to assume neglible energy loss to the rotation of the wheels of the wagon.
However, there is a keypoint in this thought experiment that you seem to be missing. At the start of your system, using vectoral-energy, you have X energy "pointing down" and at the end of your system you have X energy "pointing sideways".
Normal scalar energy is conserved such that we can say delta-E of our closed system is 0, or
Estart = Efinish, right?
We get X energy = X energy.
Great. Everything looks great.
In your vectoral-energy setup, you started with downwards energy and ended up with sideways energy. What happens if we try to conserve vectoral energy?
VEstart = VEfinish?
X to the left = X down, or,
(X,0) = (0,X), or,
Xi = Xj
In other words, "vectoral energy" is only conserved if left = down, or i=j, or x=y (or whatever your favorite coordinate system is). Vectoral energy isn't useful unless you ignore direction (hinting at the fact that energy is directionless). The problem isn't with the "vectoral energy" concept.. it's with the fact that it produces gibberish results when trying to apply normal energy concepts to it, unless you ignore direction.
This is the exact same mistake the original post made.

Two good posts that I will need time to absorb before coming back to you fully.
Just as an aside, I believe I pointed out that I would initially assume any frictional losses to be neglegible and I was willing to carry on and analyse that energetically after looking at the significant factors.
Since you show good understanding of what I am alluding to I will add my thoughts now.
Because I assumed the wagon itself was a closed system then the kinetic energy of the wheels relative to the axles transforms to thermal energy which would be be output from the closed system as thermal energy. As per the slope I would consider the wheel bearings to be a mechanism that is energetically irrelevant except that it transforms the energy into a form that can cross the boundary of the closed system. In terms of friction between the wheels and the slope I would consider this the same way except that Work crosses the system boundary and is transformed into heat outside the closed system.
I would be very interested in your comments on the above.

As with your original assumption, neglecting friction altogether simplifies the model immeasurably and has negligible effects on the results.
I think you misunderstood my point about another "influence" that we are also ignoring, and that is the rotational kinetic energy of the wheels. In an actual physical analysis of this system, mgh doesn't go 100% into 1/2mv^2 of the wagon, entirely. You've already mentioned friction as one other place energy goes. The other place is into the rotational kinetic energy of the wheels themselves. A wheel that is spinning has an energy of 1/2*I*w^2, or, 1/2 of the rotational inertia times the angular speed squared.
This is why in physics 101, they usually don't use wheeled objects (or a ball) in these types of mental experiments, because some of the energy goes into getting the wheels turning, not overall velocity of the wagon. In other words, a block of ice sliding on a frictionless surface versus a ball that rolls down a hill (with 0 energy loss due to friction) do not result in the same speed at the bottom, because the ball has some of it's GPE converted into rotational energy.
For the sake of discussion, and for the sake of my posts above, it's fairly safe to ignore both effects. Or, we can reword the problem to be a block of ice sliding on a frictionless slope. In either case, my original post implies that both of the secondary energies are 0. That is, I assume that all GPE goes to KE, and none goes to thermal via friction and none goes to rotational-KE of the wheels. Under that assumption, however, I posit that my post holds, and that "vectoral energy" doesn't make sense unless you 1) ignore the direction, or 2) say it's physics are wildly different from normal energy, most importantly, it is not conserved.

Yes, I had misunderstood, apologies for that but if I could outline my reasons for initially not completely understanding what you were putting forward.
I did not see the inertia of the wheels as being significant because in my mind the wheels were inside the closed system boundary and so the internal energy of the system would not be affected. I did not think it necessary in terms of conservation of energy to seperate them from the system since the kinetic energy that would get stored in them would release itself to propel the wagon at a later stage (flywheel).
Of course in my mind the wheels on the wagon are made from aluminium and have very narrow rims and a very small diameter so I neglected the kinetic energy in them. ;)
I am working on your other information between posts.
I hope that even though my responses do not contain any mathematics like yours that they are demonstrating that I do have a grasp of this subject. I will try to include more mathematics if you prefer to converse that way.

There is nothing in Killtown's post that suggests his "Link to a "normal" video?" remark is anything other than a request for a link.
Actually, since there is nothing in his post that implies anything else, I would say both possibilities are equally likely.
However, I don't see how Killtown could ask for a link for something that cannot possibly, by definition, have one, and still be able to speak English properly.
Argument from incredulity.
Speculation. :D
Next most importantly, your hypothetical poster's reply to your statement is an unnecessary addition, as there WAS in fact a follow-up to Killtown's post. WWGHA expressed confusion at Killtown's apparent request for a link to a non-internet video.
And I think you're using his confusion as the evidence you're looking for. Perhaps we should ask Killtown himself. He's probably weird enough to actually WANT the stundie.
It is entirely within the realms of possibility that everything Killtown has ever posted has simply been part of a huge practical joke and that he's having a good laugh at us taking him and his ideas as though he is being serious.
What is that ? An argument from godzilla-sized strawman ?
I really don't understand why this debate is even still taking place. WWGHA defined a "normal" video as a non-internet video. Killtown then asked for a link to a non-internet video. This is BASIC linguistic analysis...
Oh, but then he would've had to say "Can you provide a link to a "normal" video ?" He didn't say that, did he ?

Yes, I had misunderstood, apologies for that but if I could outline my reasons for initially not completely understanding what you were putting forward.
I did not see the inertia of the wheels as being significant because in my mind the wheels were inside the closed system boundary and so the internal energy of the system would not be affected. I did not think it necessary in terms of conservation of energy to seperate them from the system since the kinetic energy that would get stored in them would release itself to propel the wagon at a later stage (flywheel).
Of course in my mind the wheels on the wagon are made from aluminium and have very narrow rims and a very small diameter so I neglected the kinetic energy in them. ;)
I am working on your other information between posts.
I hope that even though my responses do not contain any mathematics like yours that they are demonstrating that I do have a grasp of this subject. I will try to include more mathematics if you prefer to converse that way.
Think of it this way:
In a space system, a vector, by definition, has 3 components describing direction from a starting point. In a Cartisian system, these are of 3 orthogonal coordinates, referenced to the start point. In a cylindrical system, they would be radial, angle, and length. In a spherical system, they are radial, angular, and angular
In other words, a vector describes a specific direction. "Outward" may be a direction referenced to a point, but it is not specific, and in truth, defines a sphere.
High to low, when describing energy does not define a direction, but statesof energy.
A vector quantity has a very specific, 3 dimensional , quantity and direction. That is in 3 dimensions, not one. The definition of "vector" has that imbedded in it.
Is that any help?

As with your original assumption, neglecting friction altogether simplifies...snip...Under that assumption, however, I posit that my post holds, and that "vectoral energy" doesn't make sense unless you 1) ignore the direction, or 2) say it's physics are wildly different from normal energy, most importantly, it is not conserved.
I have used your original quote and snipped it to maintain the integrity of the links between our posts. I appreciate that you have not been adversarial in your posts so, you probably would not interpret this negatively anyway but, I'm just kicking this off with an explanation as to why I have done it so you do not interpret this as me editing your post for nefarious reasons.
I enjoyed reading your "what if" analysis of energy as a vector. The conclusion I drew from it was that the Law of Conservation of Energy means that energy cannot be a vector since a change in direction would mean a change in energy. That was neat but, I have already accepted on here that energy is scalar by definition. I will explain this further later in this post.
After reading my posts it is probably no surprise to you if I said that I find the concept of the Stundies offensive, maybe that's just me being over sensitive. In "real life" I am a concilliatory person rather than confrontational and in my daily work I try to work to the ideal that everyone has a right to make an error once in a while and that very few people intend to make an error. In that respect if we put all our mistakes on a notice board at my workplace it would cover a wall in our facility. I don't see the need to do that and I actually find that the vast majority of people are very honest and don't need to be told they have made an error if you foster a no blame culture. In summary, the concept of the Stundies is alien to me in my professional life and I believe these type of concepts lead to negative attitude reinforcement.
I also have an awful habit of throwing things into the arena with minimum explanation during Team briefings to try to generate ideas and feedback. This doesn't work on internet forums, particularly in an adversarial setting so if I remain here I will avoid doing that in future.
One noticeable thing that did happen was the case of HeyLeroy in the March Stundies. The specifics are that he is a "skeptic" that got nominated. I spotted the difference in HeyLeroy's nomination immediately because I have seen this in my workplace. The younger Engineers will have an "in joke" with their team about something daft that one of them has done but, they are laughing with each other. If I spot "laughing at" then I am sure to say something to stop it as I consider it to be bullying and unethical.
I hope that will explain to you why I felt it necessary to give Griffin the benefit of the doubt even though I would probably agree with some that he is an eccentric Theologian not educated in Science or Engineering. Mistakenly and perhaps naively I thought that others might be persuaded to see what I percieved as an injustice so I took a more positive position (inspired by the Positivist attitude of The Almond) regarding his faux pas.
If I may, I would like to return to the starting point of this thread which by necessity repeats some of my previous points but I ask you to bear with me.

In other words I don't consider Energy to be a "God of the gaps" to explain why Work occurs. I felt that the pure definitions ignored other fields where Energy is a concept such as Thermodynamics which I have some experience of.
Perhaps I was being to indulgent of Griffin when I tackled his isolated statement from the point of view that Energy works between potential differences. Heat engines use the energy flow between the two potentials - Hotter and Colder (abstraction recognised in the terminology). Electrical circuits use energy flow between two potentials - Higher Voltage and Lower Voltage (abstraction recognised in the terminology). Kinetic Energy flows between two potentials Higher and Lower (abstraction recognised in the terminology).
No matter which direction the energy finally ends up flowing because of mechanistic designs, it's source is a contrast between two potentials or a direction.
In the simplest and purest case I can imagine of a steel ball bearing being dropped the source Energy is derived from the change in potential and this can only happen in one direction. I don't know of any case where having fallen the steel ball will spontaneously rise to a higher potential. I must take your point on board that this is a special case where our conceptual "Energy Vector" happens to be aligned with the Acceleration and Velocity.
Hope this helps.

Indeed.

Mistakenly and perhaps naively I thought that others might be persuaded to see what I percieved as an injustice so I took a more positive position (inspired by the Positivist attitude of The Almond) regarding his faux pas.
Specifically, I disagree that this is a faux pas by Griffin and instead believe he is fundamentally ignorant of the basic concepts involved. When I say something falls at "freefall speed" it's technically incorrect and what I mean is that it falls at an acceleration equal to the acceleration due to gravity. Taken alone, this is a faux pas. If the rest of my argument makes sense, you "know what I meant" and we move on.
However, if I take it one step further and say that an object was falling at "freefall speed" and fell 10 floors in 1 seconds, so in 10 seconds, it should fall 100 floors, you'd rightly say "No, that's completely wrong". My faux pas has become fundamentally wrong and based on a severe ignorance of the physics going on.
Griffin does precisely this when he tries to apply his "vectoral energy". He goes from making a simple faux pas to demonstrated fundamental ignorance of the physics being discussed.
Let me explain..
Originally Posted by David Ray Griffin

He is trying to say that gravity alone cannot provide the lateral forces necessary. He leaves out his implied (and very wrong) assumption that "vectoral energy is conserved". In his mind, since GPE "points down", things need to go down, not sideways. In his mind, "vectoral energy" is conserved. "Downward pointing" energy can only result in "downward" things. As we've established fairly easily, the concept of "vectoral energy" is most certainly not conserved, therefore his entire argument is fundamentally flawed.
Even if we say, yes, the concept of vectoral energy exists, and yes GPE points down, it's completely incorrect to say that it is "conserved" and consequently cannot cause lateral "forces" or "releases" or whatever other term you want to use. It's fairly trivial, in fact, to show that "vectoral energy" can and does change direction under specific conditions. Therefore, the fact that GPE "points down" is meaningless when trying to remove gravity as the "original" source of energy for lateral movements in the tower collapse. This is exactly what Griffin is trying to do, and it's fundamentally wrong.
The real problem here isn't the concept of "vectoral energy" as much as it is trying to apply the physics of standard (scalar) energy to this "vectoral energy" concept. The ignorance isn't in saying that GPE "points down" as that is a forgivable mistake and I'd know what he meant if he was making a cogent argument. The problem is he's not making a cogent argument because he's trying to apply scalar energy laws to a made-up concept of "vectoral energy" to prove a point. His made-up concept does not follow the physical laws he's trying to apply to it.

And I think you're using his confusion as the evidence you're looking for. Perhaps we should ask Killtown himself. He's probably weird enough to actually WANT the stundie.
What is that ? An argument from godzilla-sized strawman ?

There's really not much I can say here that I haven't already addressed...I will clarify some things though:
1) Saying that you don't think that Killtown was asking for a link to a non-internet video because you don't believe Killtown would be stupid enough to ask for a link to a non-internet video is pretty much a textbook case of the argument from incredulity. Not speculation on my part.
2) My comment that the everything that Killtown has written could be a joke wasn't a strawman argument. It was a perfectly valid description of how things could be - we cannot say for certain that this is NOT the case. The example was meant to highlight the fact that when there is a far and away more probable explanation for a comment, it is perfectly valid to assume that the more probable explanation is the correct explanation.
As for why this is the more probable explanation - I've already gone over this in my previous posts to William. There doesn't seem to be anything you've brought up that I haven't already addressed in my analysis.
And as a favour, in case William has put me on ignore, could someone please quote the posts I wrote to him. He seems to think that if he ignores that he's been exposed as a liar it will go away. This is not the case.

Killtown is one big stundie and not a very nice guy. Killtown makes up stuff about a 9/11 photo which shows the smoke from flight 93! It looks just like a aircraft smoke cloud you can find many times over on the internet from airbus accidents to B-52 accidents. Almost an exact match for how a crash smoke rising looks like.
Killtown asking for a internet link to a physical video tape would be a good studie, unless he was searching to buy the physical tape. STUNDIE nomination approved! No opinion, just facts. John Swift would agree.

Is this an explicit admission that you were wrong?
If so, then I am satisfied. There is no need to answer any of the other questions I asked, (unless of course you wish to do so anyway).
The two main points I was trying to make by starting another thread still stand, however.
1) Unless we can agree to a common language for describing physics concepts like "energy," "moment of inertia" and such, then I am not going to return to the WTC thread where we both posted some images. I have neither the interest or the energy (hah! a little joke there) to go off on tangents like this 'energy is a scalar' every fifth post or so.
2) In my opinion, a formal education in science/engineering is irreconcilable with such things as the need to convince you that energy is a scalar and chipmunk stew needing to clarify what he meant by 'momentum' as differentiated from 'kinetic energy.' If you don't wish to post your credentials, that's fine with me - simply say so rather than becoming disproportionally offended by the question. I will simply voice the assumption that I am not the only one on this forum to feel this way - and predict that these are not the last such arguments, disagreements and miscommunications you will face here so long as you insist on using words and asserting concepts that fly in the face of well defined standard science.

Since Mr. Rea has publicly noted that he will not be responding to my posts, I'll simply summarize the relevant parts of the thread and let any readers decide for themselves (Follow the quote links for Mr. Rea's full posts)
Gravitational Potential Energy acts and releases in a vectorial manner.
In comment to your post, I am being told that energy has no vectoral element so it appears that whilst it is apparent that everyone knows that gravitational energy makes stuff fall down this is simply not so.
I am saying that energy has a vectoral quality, specific examples being that gravitational energy can only be released in one direction which is commonly referred to as vertical
B. I haven't claimed that energy isn't scalar, I simply asserted that it has a sense of direction like a vector and no one as yet has shown me that it doesn't.
I still contend that whatever euphemism you use gradient or vertical there is an instinctively directional or vectorial nature to energy.
In fact Energy has a direction which is towards equilibrium.
And then back to ...
The conclusion I drew from it was that the Law of Conservation of Energy means that energy cannot be a vector since a change in direction would mean a change in energy.
And just for completeness...
Be reassured that if I am wrong I apologise, I have a record for doing this on the forum, in fact I believe that I am probably one of a handful of people on here with the humility to do so when proven wrong.

@ Thread
I have been carrying out some ongoing experiments for the last week or so which I would like to publish my initial results on the first one...
Experiment 1
A pebble of mass 0.25kg was placed on the ground in my back yard. On a twice daily basis the height of the pebble from the ground was observed for any changes that might indicate a change in the GPE state of the pebble. The pebble is 0.01m high so the measurement of the initial height hi was taken from its centre of mass at 0.005m high. The results to date are as follows...
Obs Height
hi 0.005m
1.2 0.005m
2.1 0.005m
2.2 0.005m
3.1 0.005m
3.2 0.005m
4.1 0.005m
4.2 0.005m
5.1 0.005m
5.2 0.005m
6.1 0.005m
6.2 0.005m
Obviously, it is early days yet but I would like to ask the more scientific on here if they could run this experiment concurrently with me. I am wondering if a pebble of much smaller mass might statistically be more likely to achieve greater than 0.005m height (from centre of mass). I may start to take temperature tests of the surface of the pebble to see if the heat energy of the sun might be affecting the experiment, any theories on that? I am also wondering if my measuring equipment might not be accurate enough to measure the change in height that would result from any spontaneous flow of GPE into the the pebble.

I put a gallon drum of water in our shaded garden shed two days ago and on a daily basis measured the temperature of the water when the outside temperature was between 20 and 22 degrees C (We are having a hotter than average Spring over here). Using the Temperature of the water as a guide to a change in its thermal energy state I made the following preliminary observations.
Obs Temp (degrees C)
1.1 18.6
2.1 18.5
Early days yet but I'll keep observing.
Obviously, Mrs Rea is not scientific and thought I was mad but, she soon latched onto it when she realised money was involved and expects us now to save thousands of pounds sterling on our heating bills simply by waiting for a spontaneous increase in the thermal energy.

I may start to take temperature tests of the surface of the pebble to see if the heat energy of the sun might be affecting the experiment, any theories on that? I am also wondering if my measuring equipment might not be accurate enough to measure the change in height that would result from any spontaneous flow of GPE into the the pebble.
Why is Jew Hating in your avatar?
Are you protesting the Red Cross, or knocking idiot neoNAZIs.
Who are the Jew Hating idiots you are protesting?
Why does an engineer have so many problems with gravity and physics. (dynamics)
rocks?

@ Anti-Sophist
If you are still lingering in this thread I would appreciate some commentary on the diagram in the attached link.
http://forums.randi.org/showthread.php?postid=2491662#post2491662
The diagram is from a Bazant Paper presented at the 15th U.S. National Congress of Theoretical and Applied Mechanics.
As has apparently already been pointed out, the quantities in the red box appear to be forces, which are vectoral in nature. The force due to gravity is mg, where g is a vector. Therefore the force is also a vector as a scalar multiplied by a vector remains a vector. By an identical analysis we were able to determine that energy is not a vector because it consists of a scalar mulitplying the dot-product between two vectors. This quantity must be scalar.
Energy is nothing but the dot product of a force with a displacement. This always results in a scalar quantity. The physics of forces is well understood and it's interation with (scalar) energy is also well understood.
I fail to see the relevance to the discussion of the concept of "vectoral energy". Are you implying that there is some relationship between forces and "vectoral energy"? And I repeat, there's nothing inherently wrong with "vectoral energy" other then the fact that there are no useful laws of physics that govern it's behavior. Furthermore, the entire presmise of the discussion is the ignorance that it belies when one tries to use the laws governing scalar energy to "vectoral energy".

William, what exactly are the purposes of your experiments?
It appears as though he is in the process of constructing some sort of strawman that will have something to do with spontaneous changes in energy.
