I can follow Susskind's lectures about gravity. I understand metrics and tensors. Have you seen EW's talks? What was your take? I found them impenetrable and impossible to follow. Perhaps it's just me and my ignorance. But I happen to believe that a real expert in a field can explain it to a non-expert. By that measure, EW has not demonstrated expertise.
- senderista 3y agoSorry, at first I read "EW" as "Edward Witten" and was like "of course I wouldn't expect to follow any of his talks!" :) But no, I haven't seen any of Weinstein's talks. TBH I don't have a real physics education (just did independent study of GR as an undergrad), so my knowledge of QM/QFT is far too weak to really follow pretty much any technical talk on quantum gravity.
- empiricus 3y agoThe funny part is that the beginning of the EricW talk mentioned by the grand-parent comment is just a summary of the another EdwardW talk, so of course it was hard to follow :) Well, it was nothing controversial, just a super high level description of the current physics theories (general relativity and quantum field theory).
