Gee, I hate differential equations, but I'm interested in math modeling. It's like sticking your hand into a garbage disposal for a sweet, sweet jewel. The garbage disposal is on. And there are flesh eating, garbage disposal immune monsters in it. And it's filled with lemon juice and salt.
This hasn't stopped me from attempting to model the zombie apocalypse on my own time and it's not stopping me from doing this now.
I saw the ad on my way home and it struck me as, "That rate has to be way too high." I've seen others like it, like one was that every 57 seconds (or something) customers switched to whatever company it was. Again, seems way too high a rate, but let's try and figure if that's right.
What I want to figure out is a rough ratio of the, "kids with autism," to total number of kids in the world using the, "every 20 minutes," rate. Let's assume that the diagnosis aren't, say, second opinions and that each child gets one diagnosis. Because I'm simplifying things (for now), let's consider children to be between the ages of 0 and 17. Let's also assume that none of them reproduce. Oh, and no, "degree," of autism. Let's make it either the kid isn't or the kid is.
For both, we'll have some initial population. I'm thinking that for the total population we can allow the rate of growth to be independent of the population (and that can just be the overall world birth rate I guess, when we start putting in numbers) along with the rate of decrease (harder to get, do we just consider changes in est. world adult population?), so it's more of an immigration-emigration. For the autistic kids, we'd would add them in at the rate being used.
So, before I go any further, can anyone tell me if I'm at least setting this up right or am I going about the entire problem wrong.
