Hello la team ! Est-ce qu’il y a des personnes parmi vous qui sont là pour les devoirs pour UniLaSalle Beauvais ? Si c’est le cas manifester vous ont peux peut-être crée un groupe pour s’entraider ça peut être super utile et tout 😀🥳✅
Certainly a nice talk on Feynman, and for the most part on Particle Physics (Standard Model, QCD). However, throughout this video, it became unclear who was the intended target audience. Some of the content could have been a day-1 introduction to Particle Physics, but there were frequent a priori assumptions that the audience also knows all of the technical graduate jargon of the presenter, with gems thrown in like the intimidatingly long path integral equation glossed over rather quickly, graphs equally glossed over, and "Nonabelian SU(2) gauge theories", and "normalisation theory" glossed over as if it had explanatory power, without any description. I worry that this sort of mixed presentation scares off both the interested amateur physicist looking for something less intimidating in an introduction to the field of Particle Physics, as well as the graduate physicist years, ahead of asking the basic questions like 'what is a quark' and 'what are the fundamental forces'. This might be a contentious opinion, but regardless, I'm glad these lectures are shared.
I see what you are saying, it's a fair observation. I have a feeling (no evidence though) that this would not drive away passionate people interested in particle physics. I am currently a PhD student on particle physics. Some seven, eight years ago I used to watch/read lectures like this. And you are right, I would not understand most of it. But that never drove me away from undergoing the endeavor of working of particle physics. If anything, it made my aspiration to understand particle physics even greater.
----I'll take the second one: Corporations don't want to hear from you, they just want your money and information, they don't care what you have to say or what your issues are. Google/UA-cam IS the evil empire, run by a bunch of Marxists that think they are doing us all a favor.
The word shift from precision to accuracy betrays a rather big problem. It is precise, it is not accurate. For example it does not account for, include, or predict gravity. As a result it can't even appeal to rigorous measurement of time or distance. It is not then so successful as portrayed.
I am in no way a professional physician, but aren’t you afraid of violating the higgs field by generating such huge amounts of energy in such small spaces, which might cause vacuum decay? Please tell me, if what I‘ve said is absolute garbage or not.
21:30 The claim QCD solves Dirac's large number problem is hilarious. Gross should take a look at Dirac's paper rspa.royalsocietypublishing.org/content/165/921/199.

Je patauge dans la semoule
Totalement !
Oui moi je suis là pour Uni LaSalle Beauvais! J'ai un peu de mal là….et vous ca va?
On est ensemble les frères !
On devrait crée un groupe ou un truc comme ça
I SALUTE YOU, DAVID GROSS, WHILE THESE TENNESSEAN'S THUMP THEIR BIBLES!❤

Can anybody tell me why UA-cam still has a "Show More" button when this feature is no longer available? Also, why UA-cam has no public email address?

He is Gross, no doubt about that
Thank you for an excellent overall lecture with an exciting challenge found at the very end !
Man Im glad I was there :]
i love his shoes!

Yes
I have performed a measured of the present and determined it to be 1/pi seconds long.
the future of particle physics is rather Bald and Brilliant

omg. its doc emmet brown irl!
If u can't prove string theory then it better to discard it very soon as possible
AdS/CFT trick is a trick without a solid physical sense. It doesn't resolve the QCD problems, just mimics models with ad-hoc assumptions.
I don't know what is "desacopled Quantum system" but im my practice in high-energy hadron scattering this "method" gives nothing!
Particle Physics is dead, move on. The infinite universe is a hologram.
@StringGene Well you might be right but do you have any sources to prove your claim?
