New XKCD: "Differentiation and Integration"

Today's XKCD, about the algorithmic difference between symbolic differentiation and integration, is superb!

My favorite step of integration is "burn the evidence". ;)

The Consequence of Calculating Annular Areas in Calculus

Well, or at least the consequence of making successful scientists feel bitter about it, as told by Saturday Morning Breakfast Cereal.

This Happens to Me All the Time

Sometimes, you're in a dark alley, and somebody points a gun to your head and demands the answer to a calculus question. Seriously. This happens to me all the time.

Mathematical Integration

Steve Strogatz's latest column in the New York Times is on integral calculus.

The Calculus of Change

Here is Steve Strogatz's latest column in the New York Times. In it, he discusses differential calculus (after he discussed differential geometry... go figure). Integral calculus is supposedly coming next week.

(By the way, this is blog post 1998. Soon we're going to party like it's 1999.)

Rectangling the Circle

In Steve Strogatz's latest article in The New York Times, he discusses limits and presents a nice proof that the area of a circle is π*r^2, where r is the radius of the circle. (The proof that I saw in calculus was with an integral, but this one in Strogatz's article is much more clever and insightful.)
