Basic Concepts: Fields

In the initial “Basic Concepts” post, I discussed the concept of Force in physics. This time out, I’ll be talking about fields, which is a much dicier proposition. Not only are fields considerably more abstract than forces, but I’ve never lectured on fields in general (specific instances of fields, yes, but not fields as abstract… Continue reading Basic Concepts: Fields

Physics of Weight Control

Scott Aaronson lists his favorite foods, and says that he expects to weigh 3000 pounds by the time he gets tenure. Jenn Fallis explains his mistake: he’s a theorist. Experimental physics can provide a built-in exercise problem as you haul bits of apparatus from one place to another. Theory’s sitting-at-a-desk-staring-into-space program just can’t compete…

The highly preliminary schedule I received a couple of days ago includes a Saturday afternoon talk on “Spooky Action at a Distance,” which will be a sort of popular-audience explanation of the EPR Paradox and Bell’s Theorem. “Weird Quantum Phenomena” was… Continue reading SF and the History of Science

Tom Brady

My Giants are done for the year, but Kate’s Patriots are still in it, so there will be football-watching this weekend (well, actually, I’ll be playing in an intramural basketball game for a good chunk of the Pats game, but Kate will be watching). In honor of the Pats, then, here’s a video for Kate,… Continue reading Tom Brady

The Problem of Charles Murray

Charles “The Bell Curve” Murray is back with a three-part essay series on edcuation, published in The Wall Street Journal: Part I: The world is full of stupid people. Part II: Too many stupid people go to college. Part III: We should spend more money on the tiny fraction of people who are smart. (You… Continue reading The Problem of Charles Murray
