Math series at The Opinionator

Steven Strogatz, a professor of applied mathematics at Cornell, is blogging at the New York Times' Opinionator about math for the next several weeks. In today's post, he talks about his plans for the series:

I’ll be writing about the elements of mathematics, from pre-school to grad school, for anyone out there who’d like to have a second chance at the subject — but this time from an adult perspective. It’s not intended to be remedial. The goal is to give you a better feeling for what math is all about and why it’s so enthralling to those who get it.

His first post starts with preschool and includes a video from Sesame Street that addresses the question, "Why do we need numbers?" You can read his post here
