He is, of course, a renowned professor from Princeton University, and he has written extensively on science. He gives a talk here on how life might have evolved in the outer regions of our solar system, and he has provided a unique way on detecting such life forms. 
Not only that, I learned about the Battle of Princeton as well as a Canadian expression from his talk. He is truly an entertaining speaker.
