Did you know Feynman is a brilliant lockpicker and had frustrated quite a few notable scientist of his era during the Manhattan project! Here is Feynman after cracking open a safe that contained very important documents related to the atomic bomb:
“……I would tell how I opened safes whose contents were bigger and more valuable than what any safecracker anywhere had opened - except for a life, of course - but compared to the furs or the gold bullion, I have them all beat: I opened the safes which contained all the secrets to the atomic bomb: the schedules for the production of the plutonium, the purification procedures, how much material is needed, how the bomb works, how the neutrons are generated, what the design is, the dimensions - the entire information that was known at Los Alamos: the wholeshmeer!"
