why it actually matters
It’s been a while since I’ve posted anything here – I’ve been pretty busy with work.
In earlier posts I’d mentioned interesting articles on mathematics by Bill Thurston, Terry Tao, and Paul Lockhart. Today I’m going to try and relate these articles to the topic of educating children
