Theorem of the Day

Theorems by Women Mathematicians

Twelve of these theorems have been compiled into a 2008 calendar: you can find more details here. I fully intend to do the same again next year, so this list will double in the course of the next twelve months. Do let me know if you have any suggestions for beautiful theorems which lend themselves to my one-page format.
