- And here I am, thinking I discovered "glueballs" in elementary school when we were given rubber cement to use.by Hobadee
- Oh no. A new particle. Who would have guessed %]by bronlund
- AI-made?by germandiago
- Interesting how should someone uses it IRL at the end of the day
- are we going to have force-fields now?
- No.by krapp
- We have them now. You are not floating into space because of one right now. Also magnets.
- Isn't it significant in some sense that this was discovered in China first, and not the US?
In the sense of: we didn't know splitting the atom would change warfare forever, back when Einstein and others published on it. We don't know if there are discoveries of similar impact lying in wait somewhere. If China gets to such a discovery first, we are in Sputnik territory, to say the least.
by hdivider - you are trying to see something that's not quite there in this case. there is shit ton of very good research that happens all over the world. but i also sympathize with what you are trying insinuate and that's also probably happening.
- Plenty of things get discovered all over the world and this isn't a particularly earth shattering result. Discovering evidence of a particle predicted for 50 years is interesting but still pretty mundane.
The LHC which is doing much of the particle physics discovery is in Switzerland and France, if you need to be reminded, not the US.
The first strong force theory was published by Hideki Yukawa in Japan in 1935 (which won him the nobel prize) ... so uh, not exactly a sputnik problem.
Sputnik problems (and the nuclear race) are engineering and industrial races, not fundamental physics ones.
- But nuclear fission was discovered by scientists working in Nazi Germany (except Meitner who had fled to Sweden by then).by wiml
- Einstein? Rutherford, I thinkby peterashford
- We knew. That's why Roosevelt started the Manhattan project after scientists wrote to him warning about it, to be sure that the Germans or the Soviets didn't develop it first.by SoftTalker
- It's foundational science. The US scuence system calls for utility and time to merket. In such a system there is little space for gluons.by jhoechtl

- This led me on a 1.5 hours long, entertaining chat session with Gemini learning about stuff in Physics - hopefully without much hallucinations. But definitely with a lot of typical - "You have arrived at a great insight.." like egging on by the AI :D
But learned a bunch about bosons, fermions, QCD, gluons, Kugelblitz, composite bosons and finally Noether’s Theorem on symmetry. Was a wild ride
by 4mitkumar - share the thread ?by nobrains
- How do you plan to make this newfound knowledge 'stick'? Do you have enough relevant/related knowledge that you'll remember it? Or is there a way to have Gemini make a bunch of cards for use with spaced repetition software?by apparent
- > After almost two decades of searching, a team of physicists in China says it has observed strong evidence of a mysterious particle called a glueball, which is made entirely of force-carrying particles. > ... The discovery of glueballs would provide direct evidence that gluons can interact with themselves, researchers say. This is a key prediction of quantum chromodynamicsby lorenzohess
- Why do they call it a "mysterious glueball" if the theory predicted it?by amelius
- > "quantum chromodynamics"
I had to google it: "the study of the strong interaction between quarks mediated by gluons"
