Feynman's ability to give an off the cuff lecture is astounding and probably an area where he is world class. I think of the one recorded interview with him, and his shockingly deep answers to simple questions that were off the cuff. His response to "why do magnets push/pull eachother" and what the issue is with asking "why" requires a lot of introspection is stellar.

I linked the "why do magnets do that?" interview elsewhere in the comments, but if anyone else missed it I highly recommend it: https://www.youtube.com/watch?v=Q1lL-hXO27Q
