In honor of the upcoming #WomenInPhysics Day, let's create a thread of amazing women physicists. I'll start with one my favorites, Chien-Shiung Wu, who is best known for conducting the Wu experiment, which proved that parity is not conserved. ⚛️ 🧪 👩🔬 🎢

This year's edition of Rings of Fire!
Students are given initial height and velocity of the launched marble. Each group has to calculate the height of their ring at their assigned horizontal distance.

One of my favorite effects. They sense the environment with electricity and if both use the same frequency, signals collide. So they have to detune. But who goes up and who goes down on a matter of social dominance!! Oscillation as a social construct!!
Wow this is wild 🤯

Interesting question from 11yo Young Bill: what's the 'average' of a circle and a square? After a couple of questions, he clarified that he meant in terms of distance from their common centre, and he (quite impressively, imo) built the thing in Geogebra. I've […]

The first (1955) Danish edition of Ray Bradbury’s FAHRENHEIT 451. Later editions did not convert the title, so this is the only SI-compatible edition! 🎢

It’s a tradition that I ask my “Physics III” class to create some memes about our class material. It’s *also* a tradition that they’re super good at this. Please enjoy, like and share! 🧪

I know AI is everywhere in our lives, but this one really surprised me. I'm uploading my recommendation letters, and Naviance has offered to write my rec letters for me, using just 4 bits of information from me.

The new surface-colouring option in @desmos.com 3D allows a cute way of visualizing conic sections.

(The option to have translucent surfaces doesn't save with the graph itself, so needs to be re-toggled on. It's important for seeing the full curves)

Later today, I'll do an introductory lecture on planet motion in the solar system. Here is an animation I prepared for that. It shows, to scale, the orbits and motion of Earth and Mars. The yellow line is the direction in which we here on Earth observe Mars. And as you can see in the video, 1/ 🧪🔭🎢

He says it right there in his first post. These people never learn.
