Blogger is keeps eating a long post I have on van Fraassen’s view of explanation. I don’t have the patience to mess with it any more tonight, so I wll simply point out that recently (since February 2007 I guess) a very easy installer for LaTeX has been available on Mac. MacTeX offers a painless installation of LaTeX, the TeXShop front end, and the Excalibur spell checker wrapped up in a 700 mb .dmg file. I recently put LaTeX on a friend’s computer and walked them through using it, and it was the easiest installation of it I’ve done. Heads and shoulders above the old i-Installer way, although that was kind of neat in itself.
