Ain’t No Party Like a SteelyKid Party

I’ve mentioned in a few places that SteelyKid frequently comes home from school/ camp/ day care singing garbled versions of current pop hits. So for the first time since about 1990, I added a Top 40 station to my car radio presets, so I would know what she was actually trying to sing. This leads…

Holiday Thermal Physics

One of my Christmas gifts this year was a Seek Thermal camera, so I can continue my transformation into Rhett Allain. What’s this for? Why, physics, of course. Such as this video of the operation of the Christmas pyramid my parents picked up in Germany, and had set up at the start of Christmas dinner:…

Eureka: Collecting the Origin

Almost everybody, regardless of what side they favor in the culture wars, knows that Charles Darwin was the first scientist to come up with the theory of evolution. At least, they think they do. In fact, lots of people had the general idea long before Darwin, including his own grandfather. We remember Darwin not because…

High Precision, Not High Energy: Video

Back in August, I gave a talk in Stockholm at the Nordita workshop for science writers, about precision measurement searches for physics beyond the Standard Model. There’s now video of this online: The video quality isn’t great, but if you’d like a clearer look at the slides, I’ve posted them on SlideShare. The talk was…

Eureka: Bridge to Dark Matter

The first time you hear about dark matter, it sounds kind of crazy– asserting that we’re surrounded by tons of invisible stuff is usually a good way to get locked up. But the process of its discovery is surprisingly ordinary: it’s just what you do when you play cards. Here’s the second green-screen video I’ve…

Eureka: Quantum Crosswords

My new book comes out one month from yesterday, or four weeks from tomorrow. Of course, yesterday was Sunday, and tomorrow’s a federal holiday, both lousy times for promotional posts, so I’ll drop this in today instead. Here’s a promotional video I put together, about how the history of quantum mechanics can be compared to…

I’m teaching relativity in a course with an astronomy prefix, which means I’m obliged to talk about stars and stuff. Yesterday’s lecture was about neutron stars, and how their existence was confirmed by the discovery of pulsars (with the story of Jocelyn Bell Burnell included). This requires some discussion of angular momentum to explain how…

Entangled States at TED-Ed

The fourth video I wrote for TED-Ed is now live: Einstein’s Brilliant Mistake: Entangled States. The title is not just an Elvis Costello reference, but gets at the fact that while the Einstein, Podolsky, and Rosen paper was wrong in that the local hidden variable theories they favored are impossible, it turned out to be…

Schrödinger’s Cat at 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…

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…
