Yes, that’s two links in a row that have not worked. 😢
All very good points!
We worked hard on these experiments, and the results are pretty spectacular!
Wow…never seen that before. That’s truly remarkable!
Wow, this is a great problem. I’ve pondered, went down two wrong paths, and now think I have it figured out. Surprising answer.
Do I dare? So, so, so, so close…
An evening with Adam Savage, with Matt Parker as the emcee at G4G16. Adam’s talk was funny, deep, intellectual, and touching. What a great event!
Donald Knuth gives a Q&A. “I’m like Gemini. I’ll answer anything, but my answers may contain errors.”
I’m attending my first #G4G gathering, and so far I’m loving it! Here is my colleague @divbyzero.bsky.social giving a talk on interesting number tricks from simple dynamical systems!
If you haven't seen it, @allthingsphysics.bsky.social has some nice animations: youtu.be/TDAXW0iAIQo?...
I also used Algodoo to show similar vectors: www.youtube.com/watch?v=2Cnn...
I watched this as it happened, and was as stunned as she was!
Although the article is behind a paywall, there’s a nice video abstract that describes the main content.
Energy loss and jerk on the loop-the-loop pubs.aip.org/aapt/ajp/art...
I’ve read a few AJP articles over the years that discuss rider comfort, and minimizing jerk is one thing that’s always mentioned. There’s one in particular that involves a loop-the-loop that I found particularly interesting from an intro physics perspective. I’ll try to find it and send a link.
Heh…we got word the campus would be closed last Friday, a dramatic change from 25 years ago, when we NEVER closed!
Got a nice little shoutout in the latest issue of #ThePhysicsTeacher about #schlieren imaging and #SeeingSound.
Visualizing Sound and Schlieren pubs.aip.org/aapt/pte/art...
Can someone please clarify whether this affects glowscript. I’m only an occasional user of WebVPython, but would hate to lose what I’ve created over the years.
‘Twas a tough one today. Took me 6 (whew!).
I can’t remember what his role was. His PhD was from the University of Michigan.

I realize this is a long shot, but did you happen to know Phil Keston? I worked with him when I taught at Santa Clara University.
Sharing again in case you missed it. I’m surprised this video hasn’t gained a little more interest. Aren’t people interested in seeing a sound waves? Where are all the physicists?

Hmmm, I’m no mathematician, but I would think “where n∊A” means “for all.” After all, n∊A says “n,” not “some n” suggesting no exceptions, right?
Can you provide a little more detail? Most diffusion demonstrations aren’t actually diffusion, and I’d love to have a good one at my fingertips.
Wow! I’ve been there many times, but I’ve never seen it like that!
By the way, this video was made with one of the authors of that article. If you watched the video you probably already knew this. This article is the reason I got interested in schlieren imaging in the first place.
My wife teaches math in a public high school, and teaches the lowest math level. She says there is a lot of pressure not to fail anyone because the school can’t handle the backlog. Everyone just gets pushed through the system. This is not the quite the same issue, but I think there’s a connection.
I too have seen a similar thing. Thankfully, it’s been in relatively small numbers so far, but it’s always surprising when a student can’t do basic algebra but has passed the prerequisite calculus class.
Actually, no. It was the slicing a cube into a million pieces. I found that quite tedious, and AI was a big help.
Schlieren imaging really feels like magic. You do some fiddly adjustments with a lamp and a camera together right at the focus of a curved mirror, and suddenly the fiddliness becomes sensitive to tiny variations in the air density near the mirror itself.
The "oh, wow!" moment for me here was 1/🧪⚛️
