It really *was* aimed at über-bright dedicated Phys. majors.
Have heard a few reports from Other-majors re. how that original series went:
Mainly (after first couple..) ^Zoooom^ ... even though created by authentic genius.
As New Edition remarks indicate: there was room for A Lot of rethinking maybe of the sort, just How Many? abstruse deductions-from-[n+1] Brand-new Ones
delivered in Light-speed-succession: can you expect can be 'grokked-to-medium-Fullness'?
(Even at The Institute?)
ie Pedagogy just doesn't come easily, as a bolt-on-to vast competence 'in a field'.
Still: a bitchin Legacy none-the-less.
(And what was 'there' <'62--is a whole 'nother book..)
