A Must-See Site

It's called Theorem of the Day. I just found it, so I can't judge how accurate the frequency claim is, but Robin Whitty has stacked up an impressive collection of short, illustrated introductions to major theorems. I like his taste... two that were news to me and I especially liked in my first sampling: Nevanlinna's Five-Value Theorem and The Analyst's Traveling Salesman Problem.

Sign Robin's guestbook, spread the word, and recommend a theorem of CS theory! (I see at least 3 already, if you count unsolvability of Diophantine equations.)
