There are things in science that are awfully hard to explain despite not entirely being hard. We are wired to reason in a certain way, which might be detrimental when it comes to understanding an intricate system.
Richard Feynman, the celebrated physicist, had an interesting anecdote regarding it. In one of the interviews, he narrates how his father asked where the photons come from when the electrons transit from higher quantum state to a lower one. “Photons don’t lie inside the electron, they are just released during state transition. It’s like speech; spoken words don’t come out of bag in the throat.”, he explained. Understandably, his father wasn’t satisfied with the analogy, but there wasn’t much Mr Feynman could have done better.
In the past few months, I got an answer to the basic question I had about money: where does it come from? If I got money from James, who got it from Tim, who got it from Ken, then, who sits at the top of the chain?
