Feynman

While I've got a few more review copies backlogged around here, the next book review post is one that I actually paid for myself, Lawrence Krauss's Quantum Man: Richard Feynman's Life in Science, part of Norton's Great Discoveries series of scientific biographies. I'm a fan of the series-- past entries reviewed here include Richard Reeves's biography of Rutherford, Rebecca Goldstein's biography of Goedel, and David Foster Wallace on Cantor's work on infinity (which is less of a biography than the others). I'm not a huge reader of biographies, but I've liked all the books from this series that…
Sean Carroll and Brad DeLong have each recently asserted that relativity is easier to understand than quantum mechanics. Both quote Feynman saying that nobody understands quantum mechanics, but Sean gives more detail: "Hardness" is not a property that inheres in a theory itself; it's a statement about the relationship between the theory and the human beings trying to understand it. Quantum mechanics and relativity both seem hard because they feature phenomena that are outside the everyday understanding we grow up with. But for relativity, it's really just a matter of re-arranging the concepts…
SteelyKid, like most toddlers, knows a few songs, and likes to sing them over and over. Her repertoire is limited to "ABCDEFG" (the alphabet song, but that's how she requests it), "Twinkle, Twinkle," "Some man" ("This Old Man," which I only figured out this weekend), and "Round and Round" ("The Wheels on the Bus"). I get a little bored with the repetition, and so tend to make up my own verses, which get sideways looks from her, followed by telling Kate "Daddy's silly!" I've been posting a lot of these on Twitter over the past several days (@orzelc), but for posterity, a few physics-related…
Over in yesterday's communications skills post commenter Paul raises a question about priorities: I wonder to what extent good writers, public speakers and communicators are being promoted in science in place of good thinkers - people who can challenge prevailing dogma, invent promising novel approaches to old problems, and who have the intuition needed for deducing correct theories from just a few observations. I think of this as the "Weinstein Perelman Theory" because Eric Weinstein on Twitter has been pushing something similar with respect to Grisha Perelman turning down major math…
