As seen online:
“Richard Feynman opened a sealed safe at Los Alamos during the Manhattan Project using nothing but memory, intuition, and a borrowed screwdriver, then calmly handed out classified files to startled physicists to prove that the world’s most secure laboratory was not secure at all. He was supposed to focus on equations that would change history, yet he could not ignore the simple fact that the military treated secrecy like magic instead of engineering. Feynman overheard officers bragging about unbreakable locks. He asked for a copy of the combination system. No one gave it to him, so he studied the filing cabinets instead. He noticed scratches near common numbers, patterns in how physicists set combinations, and the lazy habit of choosing birthdays. Within weeks he opened dozens of safes across the lab with nothing but logic. He never stole anything. He left polite notes that read, “Please improve your security.” Some generals were furious. Others were terrified. Feynman kept telling them that the point of science was honesty, not ceremony.”
