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 […]

General Relativity With Toddler Toys

A couple of times last week, I mentioned on Twitter that I was going to demonstrate relativity with toddler toys and string. This was an inspiration that hit late on Thursday, when I was trying to think of a better way to explain embedding diagrams (the technical term for those stretched-rubber-sheet pictures that everybody uses […]

Happy Pip Day

Exactly three years ago today, The Pip arrived, in a manner that will allow him to kill Macbeth should that become necessary. This is the age where kids first become aware of the concept of birthdays, so he’s just a tiny bit excited about this. He’s a fast-developing Little Dude, chattering more and more every […]

Playground Physics: Angular Momentum, Video Homework

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 […]
