Most disturbing photo ever
Sunday, May 15th, 2005Sigfpe, our most prolific commenter, has the most disturbing photo ever on his weblog.
While going some boxes the other day, I found an index-card-sized piece of paper with a commutative diagram on it, but no other text. Where does it come from? I have no idea. For all I know if you leave any box alone long enough, it starts to sprout commutative diagrams.
