"i'm sitting next to a swimming pool and somebody dives in. i think of the waves that are formed in the water. and when there is lots of people who have dived in the pool, there is a very great choppiness of all these waves all over the water. and to think it is possible maybe that in those waves there is a clue to what is happening in the pool, that some sort of insect or something with sufficient cleverness could sit in the corner of the pool and just be disturbed by the waves and by the nature of the irregularities and bumping of the waves have figured out who jumped in where and when, and where and whats happening all over the pool. that's what we are doing when we are looking at something." richard feynman
