Fine Tuning Argument question

[Dancing David]

Over is R&P there is the rehash of the Fine Tuning arguemnt, the anthropic principle.

Some one quoted Just Six Numbers by Martin Rees

And the part i am interested in is this

Another number, Є, whose value is 0.007, defines how firmly atomic nuclei bind together and how all the atoms on Earth were made. Its value controls the power from the Sun and, more sensitively, how stars transmute hydrogen into all the atoms of the periodic table. Carbon and oxygen are common, whereas gold and uranium are rare, because of what happens in the stars. If Є were 0.006 or 0.008, we could not exist.

Is Є the fusion binding energy?

Is Є the fusion binding energy?

I think he means the fine structure constant, \alpha, which you may know better as 137.036 (it's dimensionless). It's not mentioned elsewhere in that PDF, and I would expect it to have been.

By 'fusion binding energy' do you mean the energy released in 4H->He reaction, or something else?

Is Є the fusion binding energy?

He means the fine-structure constant, normally called α. It has a value very close to 1/137 = .0073..., and it controls the strength of electromagnetic forces, including the energy it takes to fuse two positively charged nuclei.

Thank you!

I thought that it referred to the 7.65 Mev of a stable carbon nucleus.

It is really hard to tell, the FTA is a bunch of cherry picking by people who really want to ignore the science.
