Its called chromodynamics because the interactions are described by the special unitary group of degree 3, which is the same group that describes how we perceive color interactions.
It’s the theory of colour charge essentially, counterpart to electrodynamics. Quarks have colour, rather than electrical charge. Mediating particle is the gluon, analogous to (but entirely different from) the photon
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
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?
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.
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.
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.

Which is ironically an example of particle collider science happening overseas primarily because the US relinquished its lead on scientific discovery, despite having a similar-scale particle collider practically finished and ready to go [0].
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.
HEP is undeniably an international effort, and it's silly to try and spin this into something akin to the space race. While this is a useful and frankly brilliant potential confirmation of existing theory, that's what it is: confirmation (sort of). Without CERN, without universities across the world including all across Asia none of this would be possible.
Very few endeavors are as truly international as this because the problems are so hard to even explore, and the machines required to do so are the most complex and highly engineered on Earth. Lets not lose that international spirit in science because the blowhard narcissists who run our countries would find that temporarily useful to them.

> "quantum chromodynamics"
I had to google it: "the study of the strong interaction between quarks mediated by gluons"
Its called chromodynamics because the interactions are described by the special unitary group of degree 3, which is the same group that describes how we perceive color interactions.

Why do they call it a "mysterious glueball" if the theory predicted it?
Because it's never been observed.
mysterious: strange, not known, or not understood.
They don't really know what it is or understand it.

Best way is to build a particle collider in your back yard. If you don't have the budget, write a simulator.
You can use Gemini notebook notebooklm for this

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.
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.
Einstein? Rutherford, I think
Why not let the man himself tell you (as a surrogate for Roosevelt) the story

But nuclear fission was discovered by scientists working in Nazi Germany (except Meitner who had fled to Sweden by then).

Interesting how should someone uses it IRL at the end of the day
are we going to have force-fields now?
We have them now. You are not floating into space because of one right now. Also magnets.
No.
I thought a Plasma Window is a form of force-field.

Oh no. A new particle. Who would have guessed %]
And here I am, thinking I discovered "glueballs" in elementary school when we were given rubber cement to use.
