My first contact with the song was in the movie Wayne’s World, which also highlighted some of this dawning awareness. I knew it was funny when the main characters, Wayne and Garth, said “Schwing!” but […]
Physicists, like the ancient Greeks, like to gossip about their gods. A few days ago, three physicists* were talking on Twitter** about a review by a fourth physicist, Freeman Dyson, of a biography of one of these gods, J. Robert Oppenheimer, and about his war with another one, John Archibald Wheeler. Physicist #1: Oppenheimer did […]
Physicists do say these things about quantum mechanics — a highly-mathematical description of fundamental reality at the bottom of which is the uncertainty principle in which the act of measuring one piece of reality screws up other measurements. The upshot is, the whole of reality isn’t measureable all at once. The more you think about […]

First up, some questions from the comments portion of the previous installment of “Ask Mr. Cosmology.” Q: Is protest against God morally acceptable?

1) The Lucasian throne is the Lucasian Chair, a funded and highly honored academic position at Cambridge University that is famous, partly because it’s currently held by Stephen Hawking and partly because its first holder was Isaac Newton. 2) Who, as you know, invented/discovered the law of gravity. Translating that equation up there, the force […]
“If, for example, I say that ‘the train arrives here at 7 o’clock,’ that means, more or less, ‘the pointing of the small hand of my clock to 7 and the arrival of the train are simultaneous events.’” […]
