I read the Wiki summary of Hardy's essay. Man, that sounds pretty sad! Of course, I will find it and read it in its entirety. By the way, the whole thing about mathematics being a "young man's game..." I think that view is an antique. It is completely dependent on the health and habits of the individual in question whether they can remain lucid enough to fuse the abstract chains of thought to produce descriptions of unknown realms. Of course, it is perpetuated by movies and such, and of course, within the field like the RIDICULOUS (in my opinion) age cutoff of the Fields Medal.And2, this looks like the kind of thing I am after, although I am concerned about the view being "dated," based on that review given on Amazon. We will see -- I have a bunch of flights coming up over the next few months so I will have ample reading time!
