Professor Steven Strogatz is the math teacher you wish you’d had. His 2010 “Elements of Math” series for The New York Times online was not only hugely popular, but also understandable and elegant in its simplicity. Now, in The Joy of X, he offers us all a second chance at math through simple “Aha!” moments that require no knowledge—only curiosity. Strogatz connects the ideas of math gently and clearly to literature, philosophy, law, art, and even pop culture. A Town Hall event. For more information, click here.
