Down votes are overrated. Kind of like a scowl from a passerby. Soon forgotten. The thing I remember most about Feynman was his dislike of authority. During his time trying to figure out how to blow up the world, there was, of course, tight security. All papers etc. had to be locked away in "secure" file cabinets nightly. These were no nonsense safes with S & G combination locks on them. He figured out how to open these safes by trial and error, figuring out their weaknesses. How close you had to be to the real number and it would still open, that kind of thing. It was a real taboo to leave your office with an open safe!!! He would go into the security officers office and open the safe and leave a note in it. Thought it was funny...... They hated him.
