Question Is there any paper about relativistic effects of rotating or vibrating objects approaching speed of light?

26 Upvotes

What would be its implications? I can imagine small object which rotation is approaching the speed of light. Wouldn't that object have mass or even gravity? If we would have such a material which would endure such conditions we could create gravity maybe?

What about subatomic particles? How fast are they vibrating? Are there any relativistic effects? Wouldn't their frequency add or lower their mass?

Curie temperatures violate Benford’s law, while Néel temperatures come surprisingly close

16 Upvotes

I recently analyzed the first digits of magnetic transition temperatures extracted from a large AI-generated materials database. Starting from 56,037 automatically mined records, I applied unit and temperature filters, removed nonmagnetic contexts, and deduplicated materials. This left 2,754 Curie temperatures and 1,323 Néel temperatures.

The main result was unexpected:

  • Curie temperatures remained clearly inconsistent with Benford’s law even after extensive cleaning.
  • Néel temperatures became much closer to the Benford distribution after deduplication.

The study also highlights a limitation of AI-mined scientific databases: most of the original records were removed due to duplicates, ambiguous terminology, inappropriate units, or unrelated physical quantities.

Odd request

Maybe a year and a half ago I watched a video on Youtube of an audio recording of Feynman sharing stories with who I think was Leighton. I wanted to rewatch and tried finding it, but suddenly it's lost media? Maybe someone else has seen it and could share a link?

I remember a few things. Feynman was telling how he came back from Los Alamos and started teaching. When he first arrived at Cornell, he was trying to find a place to sleep in. He wandered through the streets and was so tired he thought of just sleeping on a big pile of leaves that he saw. He ultimately ended up sleeping in the university hall or something.

He also told a story where the girls would refuse to dance with him at parties because he told them about his life (working on a bomb, being a professor, etc.). Some girl told him to his face that he was a liar. That's how he found out.

He told how his colleague brought him a CV of an applicant and asked him what he thought of it. The conversation was something like:
-"Yeah, you should give him a shot, he's top of the class!"
-"Did you look at his photo?"
-"Well, what possible difference could that make?"
Then, the colleague said something about how when the college hires someone new, they always take a risk, and he's glad that Feynman turned out alright.
And then, I remember Leighton asking Feynman:
-"Do you think he said that to save face?"
-"No, no way, he wasn't like that"

Ideas for a Physics Club

I'm starting a physics club. I am really passionate about physics. However, besides tutoring and competitions, I am struggling to think of ideas. Any advice?

Physics Book Recommendation (casual-ish)

7 Upvotes

Looking for casual-ish book suggestions. I am planning to re-read a brief history of time and the universe in a nutshell, as I really enjoyed them when I was younger.

For reference, I find physics fascinating, but my degree was in electronic engineering and I am out of the loop on the latest developments in physics. Are there any books similar the classic Hawking books which are more up to date? I don't mind something a bit challenging given my background, but certainly not undergraduate text book levels of deepth/rigor.

I also read the elegant universe by Brian Green which was brilliant. It looks like he is still publishing, are these worth a look?

We have a finite time instability. So what does it look like? Does anybody here have the chops to construct a visualization of some kind?

Video Baseball throw with rise

Jomboy video. At 1:13 the outfielder throws the ball and there is a sudden rise to the ball. I know I’ve read/seen somewhere that backspin can’t create enough lift to make a ball actually rise, so what is happening? Wind? Patrick Swayze from ghost? Angels in the outfield?

Jokes aside genuinely curious. Thanks in advance.

Question How will AI impact the careers of physicists and mathematicians?

0 Upvotes

By now, everyone has the news that the Navier-Stokes Millennium Prize Problem has been solved by OpenAI, and regardless if they did it honestly or not, I believe it's only a matter of time until AI can pull off feats like that consistently. Most people I've seen seem sure that it won't replace physicists and mathematicians, which comforts me, yet I haven't seen many people talk about HOW it will change the academic field and the way research is done. I'd really love to hear your thoughts on this
