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.
“It’s wonderful to see such a diverse crowd,” he says. “How many of you have seen a Pixar film?” he asks after taking the podium. The entire room’s hands go up. “How many of you have seen three? Five?” He pauses. “How many of you have seen all of them?” Dozens of people raise their hands, maybe a quarter of the room. “Wow,” he says. He smiles, to himself and the crowd. This gig is not one bit bad.
