Strogatz, the NYT, and Triangular Numbers

My latest article for the New York Times Learning Network turns Steven Strogatz’s wonderful “Math, Revealed” essay on triangular numbers into a teaching and learning resource. Learn about how a favorite number pattern connects algebra, geometry, and calculus, and even extends into CAT scans the Fab Four!

The article is freely available here, and as with the articles in the series, include free access to Strogatz’s original New York Times essay.
