0:18 Do you think there have been scientific discoveries in human history that were genuinely correct but disappeared because civilization lacked the intellectual ecosystem to recognize their importance?
12:10 Is there a law governing how fast civilization can absorb fundamentally new ideas?
20:34 What would it actually mean for science to end, not because there are no more facts to discover, but because humanity had found the deepest possible conceptual framework?
33:44 ​string theory is over or not?
41:01 Is there any experimental evidence of string theory?
42:25 Do you remember the "November Revolution" [discovery of the the J/\[Psi] particle]? What was being in physics during that like?
1:38:00 Why were quarks given such weird property names (like up, down, charm, strangeness, top, and bottom?)
