#52> 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 chromodynamics

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.

#53are we going to have force-fields now?
We have them now. You are not floating into space because of one right now. Also magnets.

#54This 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
share the thread ?

Now explain how quarks have flavour!

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?
Best way is to build a particle collider in your back yard. If you don't have the budget, write a simulator.
I was waiting for someone to make a glueball joke, TBH.

#58Isn'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.
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.
That is untrue. US science is also funded by NSF grants - or were, before the Orange Idiot and his crew of apes began defunding science they didn't understand.
Much science is done by international (i.e., borderless) cooperation between teams of scientists, as well. Science is becoming, and ultimately should be, nationless.

It's just the three dimensional nature of it plus the usual physics practice of giving things cheeky names. The vector space of (visible) colors is not acted symmetrically upon by SU(3); it doesn't transform symmetrically under charge-preserving unitary matrices. A blue strawberry with red leaves would not seem the same to us as a red strawberry with green leaves.

Einstein? Rutherford, I think
Why not let the man himself tell you (as a surrogate for Roosevelt) the story https://www.atomicarchive.com/resources/documents/beginnings...
Ahh... I took "published" on splitting the atom to mean the scientific write up of having split the atom - which was Rutherford - rather than the looser meaning - having just written about the idea in general. My bad.
