Calculus in 4th grade?

Wednesday, February 20th, 2008

A while ago I discovered an interesting web site, Berkeley Science Books, that publishes a set of very comprehensive Ebooks called "Calculus Without Tears."

Friday, December 21st, 2007

I remember riding the subway to high school in the late 1970's. I rode from Manhattan to the Bronx five days a week for four years. When I wasn't chatting with one of the other kids I'd often be reading some "Mathy" thing or working out a Math problem. Yes, ...

Math history made fun

One example from Fredrickson’s web-site for his first book, Dissections: Plane & Fancy, is ...
