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

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

Tennis Ball Plus Soccer Ball Equals Blown Minds

Screen cap of the video in the post, showing me dropping a tennis ball on top of a soccer ball.

As noted last week, I went to SteelyKid’s day camp on Tuesday to talk about being a college professor. This was a little awkward, because I was scheduled to talk to kids ranging from not-quite-three to six-and-a-bit, and really, what do they care about the daily routine of physics faculty? So, I did a simple… Continue reading Tennis Ball Plus Soccer Ball Equals Blown Minds

Botany for Kids

Kate’s arguing a case in Connecticut today, so I was solo-parenting last night and this morning. which means that while I did manage to watch Cosmos last night, and have some thoughts about it, I don’t have the time or energy to write them up this morning. As explanation, I offer this video from dinner… Continue reading Botany for Kids

SteelyKid Demonstrates Relativity

SteelyKid tosses a ball to demonstrate Galileian relativity.

Before going to the playground Saturday to investigate non-intertial frames, SteelyKid and I went over to campus to do some experiments in relativity. Galileian relativity, that is: What you see here is SteelyKid sitting on a rolling lab cart with a camera bolted to it. She throws a ball up in the air a couple… Continue reading SteelyKid Demonstrates Relativity

Non-Inertial Playground Physics

SteelyKid on the merry-go-round used for this experiment.

The Schenectady JCC, where SteelyKid and The Pip go to day care, has a playground with a merry-go-round on it. How this hasn’t been sued out of existence, I have no idea, but it’s a great boon to a physics professor. I’ve used it before to talk about angular momentum, but this weekend I enlisted… Continue reading Non-Inertial Playground Physics

Uncertain Dots, Episode 8

In which Rhett and I talk about Cosmos. What, you thought there would be another topic? We have contractual obligations, you know… Okay, there were some other topics like Battlestar Galactica (both versions), why so much of what’s on Discovery Channel and TLC sucks these days, the flawed astrophysics of Firefly, speculation about how those… Continue reading Uncertain Dots, Episode 8

Uncertain Dots, Episode 7

In which we move out of the original trilogy, and into J.J. Abrams territory. Cue the lens flare! This week’s random assortment of topics includes travel, airports, physics models of loading and unloading planes, uses and abuses of curve fitting, odd stuff we get sent to review, and high-speed video cameras. Miscellaneous links: — Rhett’s… Continue reading Uncertain Dots, Episode 7
