19: Doug Natelson - Look, I'm a physicist, I have met people like Sheldon

Doug Natelson is a different kind of geek. He's an expert in the physics of nanoscale materials, but he’s also a world-class science communicator. Doug authors the blog Nanoscale Views, where he writes about a range of general interest and technical topics. We talk about his lab's studies of heating at the nanoscale, his love of blogging, and his recently published textbook on nanotechnology. (Recorded on September 1, 2016)
