(A) As a twelve‑year‑old, Richard Feynman set up a little lab in his room, bought his first radio and, rather than listening to it, he took it apart. (a) He soon became quite good at fixing radios. This was in the early 1930s, during the Great Depression, so a boy who could fix radios cheaply was useful. On one occasion, he was picked up by a client who seemed far from convinced that this boy wouldn’t be a waste of his time and money.
(B) After a while, Feynman came up with a theory: Radio sets in those days were made from a series of tubes. If (b) he took them out and reversed the order, the vibration and noise might disappear. Now, at last, Feynman was ready to act. He changed the tubes and turned the radio on. It worked perfectly. The client was astonished. He became one of Feynman’s biggest advocates, telling everyone (c) he knew of the boy who “fixes radios by thinking.”

(C) The client kept on asking Feynman how a boy could know anything useful about radios until they arrived at the client’s poorhouse. Feeling pressured, Feynman turned the radio on. It started wobbling, then gave out a terrifically loud roar for a few minutes before quieting and playing correctly. (d) He was confused. He had never encountered this before. He shut the radio off, began walking around in the room and thinking.

(D) The client was entirely unimpressed. He wanted action, and he wanted to see the boy working. He started protesting to Feynman, asking him to stop wasting his time and get on with fixing the radio, or leave. Despite the heckling, Feynman kept on thinking. He wondered how any radio could make such a noise. Most radios failed because of faulty equipment or loose wiring; (e) he wasn’t convinced it would be either.
