"Quirky" is the word I'd use, but some parts of it feel repetitive and a little disorganized. As a first pass reading it's probably still good, and it is the one that is freely available

Unit R would be great but not accessible for the whole class the way I want it too, unfortunately (don't want Ss to pay for a second text). I suppose I could interpolate between taylor & wheeler and unit R since they follow roughly the same structure

Definitely. I'm sure what happens in class matters more than the text but would definitely like to hear thoughts from folks that taught intro relativity so I feel more confident in my choice

Not yet, I've been looking at the usual textbooks so it's easier to assign problems

⚛️🎢 Looking for thoughts on special relativity textbooks. I'm doing reading quizzes for my mechanics course so I want something that is readable and freely available through our library. Spacetime physics is winning but the 2nd edition is... interesting, so I'm looking for recs/thoughts.

I have a small class in the fall so I wasn't thinking about more than spreadsheet + being smart about assignment groups on Canvas but if inspiration strikes I'll share!

stealing it for the fall!

Guess I'm adding this to the liat of things to think through over the summer

Undergrads? That's really impressive and sounds like a fun time for them too

Will likely have a copy of this to pass around when dept folks tell me we need to have to add more ai to our teaching immediately

Finally a way to get folks excited about damped oscillations!

🎢⚛️ what do your exam reviews look like? In the intro course I share attendance has been low and it's usually Ss trying to guess the exam questions from the questions I'm asking them. I don't imagine there's a magical way to make this fun but wondering if folks found something better.

Wild that people were upset about this, it's important enough to point out that every textbook I've checked recently makes this point early on to make sure students haven't forgotten that f=ma and not f=mv

Those are interesting ideas! Talking about diagrams will probably lead to a bunch of questions, and a very long problem might at least force them to keep track of things.

🎢 I have a group of students this semester that simply refuses to draw pictures/write words in their problem solutions. "Equations speak for themselves and all that matters is that the answer is correct" - any suggestions on readings to assign/approaching this? More difficult than usual this year

🎢⚛️ shameless bump for the weekend crowd. My own hot take is that tracks like these are unnecessary but I'd still like to try and do something better for students

K&K and Morin are at a slightly more advanced level so I'm looking for other texts in that space, which I'm almost convinced don't exist

🎢⚛️ I've been assigned the "honors track" intro physics course for my college next fall, and am wondering what texts folks used for this/hot takes you have. The standards seem to be Kleppner or Morin, which are... polarizing to students. Looking for alternatives and fresh ideas!

Feeling sorry for the folks I lent my code to that I wrote it before this paper - very cool stuff

Augusto Medeiros da Rosa Medeiros does research on models of particle dark matter and their astrophysical implications.

Hi @physgal.bsky.social could I get added to the physics list? Here's my physics dept webpage physics.wustl.edu/people/augus...

Oh wow thanks, that's very informative! That certainly sounds a lot less impressive then what I saw even though it is interesting. I guess ultimately I'd still prefer humans to get to do human stuff and work through our own confusion when we're missing something.

Curious for your take on this paper, it showed up on my feed as "proof AI is creative and can do research" (exaggerating slightly) right after a bunch of dept emails asking us to use more AI crashed me out lol

I guess that is the real measure of success for a good number of students, at the end of the day. I do worry about the folks who will go off to do calc 3 and beyond, but I guess they also get more chances to figure that out.

#iTeachPhysics what's your success rate at getting students to correctly use vector notation? Grading work and the amount of (vector) = (number) statements and their equivalents is rough.

Most of the lunch table talk these days is people hyping up ai for everything so it's good to see other people not going all in.

Oops, i flipped tangential and normal.

In the "classical" description of plane curves 3 and 4 would be called "tangential" and "normal", and "central" would make sense for 1 in the context, imo. I don't think normal would be especially helpful but it might be a nice place to introduce "normal vector" as a ter.

why does it happen?

Completely naive q: for even just two particles the wavefunction is a global object, so how can I think about a "local" Hilbert space if the states that live in the full Hilbert space (of the universe? not sure) should be global?
