FWIW, the NYT is running a special 25th birthday section of its Science Times today, with some really, really good articles (accessible to the non scientist) on physics, evolution, AI, physiaology, etc. Worth the read, especially if you are a know it all such as myself. http://www.nytimes.com/pages/science/index.html
OK, since nobody gave a crap I am going to post one of the more interesting articles therein: Discuss!!!!!
Ummmmmm, I'll take *just because.* Seriously, SF, thanks for the link. Haven't read any of the articles yet, but I bookmarked it as it seems more like Sunday morning reading to me.
