Once, I asked Feynman, "Can you explain to me why half-spin particles obey Fermi-Dirac statistics?"
Feynman recognized my level and said, "I will prepare a lecture for college freshmen."
A few days later, he told me, "I can't do it. I can't make the freshmen understand. It seems that I still don't truly understand this problem."
