Richard Feynman having the quantum Hall effect on his "to learn" list is amazing. I mean, it makes sense, because less than three years before he died the Nobel Prize in physics was awarded for its discovery. But it shows that even one of the greatest physicists of his generation had not fully grasped something that is now part of every undergraduate physics degree's standard curriculum and is arguably much less complicated than, say, Feynman's contributions to Quantum Electrodynamics.
