I was pleasantly surprised by the camaraderie we developed over this conversation. We start off trying to explain some of the trickier mechanisms that showed up in the "Nanobot" video, like what the heck is a rotaxane and a Brownian ratchet? There's some really cool physics going on stemming from the fact that the nano-world is controlled by very different kinds of forces than our big world. From there we talk about creativity and where ideas come from as a scientist or artist, how to build connections between scientific disciplines, how to tell a good story with science, and of course everyone's favourite question: WILL THE NANOBOTS KILL US ALL??? I had a great time in this conversation, so I hope you enjoy it and here's to many more!
