Schrödinger’s Cat at TED-Ed

Screenshot of the Schrodinger cat video I wrote for TED-Ed

The third of the videos I wrote for TED-Ed is now live: Schrödinger’s Cat: A Thought Experiment in Quantum Mechanics.This is using basically the same argument I outlined in this post, but with awesome animation courtesy of Agota Vegso. I’m impressed by how close the images that ended up in the video are to the… Continue reading Schrödinger’s Cat at TED-Ed

Trains of Clocks

Students at work on the trains-of-clocks demo.

My Gen Ed relativity course has mostly been me lecturing about stuff to this point, so on Wednesday I decided to shake things up a bit and convert a chapter of David Mermin’s It’s About Time. The idea was to get students up and moving around a bit, and actually making some measurements of stuff.… Continue reading Trains of Clocks

TED-Ed Lesson: What Is the Heisenberg Uncertainty Principle?

Screenshot from the TED-Ed lesson I wrote about uncertainty.

The second one of the TED-Ed lessons I wrote about quantum physics has now been published: What Is the Heisenberg Uncertainty Principle. This is, again, very similar to stuff I’ve written before, specifically this old blog post and the relevant chapter of How to Teach [Quantum] Physics to Your Dog. As usual, I tried but… Continue reading TED-Ed Lesson: What Is the Heisenberg Uncertainty Principle?

TED-Ed Lesson: The Central Mystery of Quantum Physics

Screenshot of my TED-Ed lesson on particle-wave duality.

My TED@NYC adventure last fall didn’t turn into an invite to the big TED meeting, but it did lead to a cool opportunity that is another of the very cool developments I’ve been teasing for a while now: I’ve written some scripts for lessons to be posted with TED-Ed. The first of these, on particle-wave… Continue reading TED-Ed Lesson: The Central Mystery of Quantum Physics

Intelligence vs. Priorities

Steven Pinker has a piece at the New Republic arguing that Ivy League schools ought to weight standardized test scores more heavily in admissions. this has prompted a bunch of tongue-clucking about the failures of the Ivy League from the usual suspects, and a rather heated concurrence from Scott Aaronson. That last finally got me… Continue reading Intelligence vs. Priorities

The Physicists of Journalism

This Alberto Cairo piece on “data journalism” has been kicking around for a while, and it’s taken me a while to pin down what bugs me about it. I think my problem with it ultimately has to do with the first two section headers in which he identifies problems with FiveThirtyEight and Vox: 1. Data… Continue reading The Physicists of Journalism

Impressive Physics Tricks for Little Kids?

We got an email from the people running SteelyKid’s summer camp asking for volunteers to speak at a career day sort of event early next week. I said “Sure, I can do that, and talk about the glamorous life of a physics professor and book author.” They said “Great, you’ll be talking to several groups,… Continue reading Impressive Physics Tricks for Little Kids?

Two Cultures of Incompressibility

Also coming to my attention during the weekend blog shutdown was this Princeton Alumni Weekly piece on the rhetoric of crisis in the humanities. Like several other authors before him, Gideon Rosen points out that there’s little numerical evidence of a real “crisis,” and that most of the cries of alarm you hear from academics… Continue reading Two Cultures of Incompressibility
