Pixar's Senior Scientist explains how math makes the movies and games we love

Pixar's Senior Scientist explains how math makes the movies and games we love: Tony DeRose wanders between rows at New York's Museum of Mathematics. In a brightly-colored button-up T-shirt that may be Pixar standard issue, he doesn't look like the stereotype of a scientist. He greets throngs of squirrely, nerdy children and their handlers — parents and grandparents, math and science teachers — as well as their grown-up math nerd counterparts, who came alone or with their friends. One twentysomething has a credit for crowd animation on Cars 2; he's brought his mom. She wants to meet the pioneer whose work lets her son do what he does.
