Question concerning the monolith in Kubrick's "2001: A Space Odyssey" 1. The problem statement, all variables and given/known data Hello everyone. I'm doing a work in which I'm explaining physical relations and coherences in Stanley Kubrick's film "2001: A space Odyssey". So far everything is doing well, but there's one problem: Can anyone please give me a possible explanation how it is possible that Dr. Floyd and his colleagues hear a painful, sharp sound when they find the monolith TMA-I on the moon. 2. Relevant equations 3. The attempt at a solution I guess it's got something to do with either electro magnetism or positive feedback. But I can't think any further. Thanks already now for helping me!
