Steven Strogatz and the Elements of Mathematics
Steven Strogatz, an applied mathematician at Cornell University, is writing a series of posts in the New York Times Opinionator blog. In his own words, Prof. Strogatz states,
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.
It's a good read, and available here. Start with the first post.
