So on the very long list of reasons why London rules is the fact that you can just turn up for things, as I did recently, like the annual Faraday Prize & Lecture at the Royal Society. (Yes, this is the same learned scientific society that was founded by Charles II in 1660 and has counted amongst its fellows Newton, Darwin, Bohr, Faraday, Maxwell, Heisenberg (no, not that one), Einstein, Oppenheimer, Crick & Watson, Dawkins, and Hawking, amongst many others.) This year's was given to and by eminent particle physicist and science writer Professor Frank Close OBE, from Oxford.
Feeling jaunty, I guess, I made so bold as to ask a question and, worse! a metaphysical one. It made it into the video. (The question immediately prior to mine not to mention its answer was better, so I start the video there. I expect we'll all know this kid's name soon enough.)
The lecture, and other questions and answers, are well worth watching.
