Hey Paul. I particularly like the two preprints I have mentioned: the Feit-Thompson preprint, which has a very nice idea, which could possibly be made to work ultimately (in my humble opinion) and the article on the fine structure constant which made me reflect on mathematical constants and contained an interesting construction, some kind of renormalization process, inspired from physics, yet applied to mathematical constants. Real numbers form a continuum. What makes special constants such as $e$, $\pi$, $\gamma$ (or $i$, if one includes complex constants too) and so on, so special to us? Of course, one may give an answer for each one of these special constants but, as far as I know, there is no uniform answer.

]]>Yes Dennis. He also did not like formulas much. They may prove something, but they do not *explain* it. I agree with him (though sometimes, this is the best that one can do, at a given point in time, before a better, more explanatory proof comes along).
