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?

You can use Gemini notebook notebooklm for this

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.

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 (whic…

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].

Oh cool, will look into this. Have only used it to make podcasts in the past. I'm a little hesitant to build in a walled garden though. I'd rather store things in an open format that can be used with many platforms, not just the one.

Matter is not a force. Matter and forces are two different things in physics. And the "strong force" is another thing altogether.

I think their point might be that matter is what defines the location of the force field. I.e. it's the EM field doing the actual work.

Yea, that is it, and I agree with them. When we say that a particle is at some x,y,z, we just mean that the space at that location behaves in a certain manner, for some reason.

And since we don't like mysteries, we say that there is a "particle" there with so and so properties..

Einstein? Rutherford, I think

Why not let the man himself tell you (as a surrogate for Roosevelt) the story

"practically finished and ready to go" is a bit of an overstatement. They made some holes in the ground, and did preliminary research and manufacturing, but it was heavily mismanaged and fantastically over budget, so congress killed it

Plasma is matter, not a force

Yet what is matter but a (strong) force

Matter is usually made of fermions (half-integer spin) whereas force is mediated by bosons (integer spin).
