Leonard Susskind's recent lecture* on the quantum origins of gravity was for me something of a revelation. I hadn't any idea that physicists had to a certain extent reconciled their notion of gravity with that of quantum mechanics. And I hadn't been particularly aware of Susskind as a physics celebrity either. He is even known for things that he has said!
I can't watch stuff that has written text without doing a bit of a spell-check. At 18:21 Susskind had written "things are not where you think the are" which he then repeated exactly at 19:40. The word "they" doesn't strike me as especially vulnerable to being typoed. Somewhat more comprehensible is the spelling at 50:28 of "communication" by the dropping of an m.
