i don't like any channels per se. i just look for random videos
here is my favorite video i've seen in quite a while:
https://youtu.be/H44IaKw8D3ctitle is french but it's in english.
i like it because it's a fairly informal conversation with literally a bunch of the top guys where they are allowed to get a bit more technical than if they were just saying stupid shit for normies. speakers are:
>david gross (nobel prize for asymptotic freedom in QCD)>gerard 't hooft (nobel prize for renormalizing yang mills/QCD)>sheldon glashow (nobel prize for electroweak theory)>francois englert (nobel prize for Higgs boson)>alexander polyakov (super respected for finding lots of shit in QCD and string theory and ads/cft)>giorgio parisi (super respected for finding lots of shit in condensed matter and neural network theory)>lars brink (super respected for lots of work in string theory)
