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/RU-vid 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.
