#433 – Sara Walker: Physics of Life, Time, Complexity, and Aliens
Sarah Walker
This one came from John Conway. I one time had a conversation with him, which was really delightful. He was really fun. But he was pointing out that if you string lights in a barn, you can program them to have your favorite one-dimensional CA, and you might even be able to make them be capable of universal computation. Is universal computation a feature of the string lights?
