Math Monday turns 100. Ladyada and Phil visited a funding meeting for the Math Museum about 2 years ago in NYC. Above, Ladyada riding a square bike. One of the cool things out of this was introducing the Math Museum folks to MAKE and for 2 years they’ve done a “Math Monday” column per week. There are 100 of them, check them all out. It’s the best math writing online. Congrats to the MAKE team and the Math museum folks. This is so cool.

This post marks George Hart’s 100th Math Monday column. The column was launched on Dec. 6th, 2009, with a piece about some fun mathematical bagel hacking. And George has been entertaining, educating, and challenging us ever since with more puzzles and projects and introducing us to dozens of mathematically-minded makers. Thanks so much for a great run, George. Congrats. And here’s to a hundred more. -Gareth

This could be a book 🙂
