Reminds me of a story I read some years ago. There’s this guy talking to his friend and the friend is complaining that his tube radio isn’t working right. The guy tells his friend that his nephew is really good at working with these things, and the friend tells the guy to bring his nephew over to take a look. So the guy shows up with his ten year old nephew, and the friend is a bit surprised but says “ok, let the kid see what he can do.” So they leave the room and the kid turns on the radio. It is silent for a bit, then starts squealing and making odd noises for a while, and then works fine. So the kid turns it off, lets it cool, and then switches the two tubes. Problem solved. The kid figured out that the second tube was putting out the crap that the first tube was generating as it warmed up more slowly. Once the tubes were swapped by the time the second tube warmed up the first tube was stable. The 10 year old was Richard Feynman. He went on to win the Nobel prize in physics for the path integral formulation of quantum mechanics. Smart kid.
