Experiments on Bessel Function Generation

This isn’t just another Newton puppy video. No, in fact it is a serious scientific experiment on the generation of Bessel Functions. Bessel Functions are mathematical functions (Google them) that describe standing wave patterns that form on constrained vibrating surfaces. In this video, they are generated in the shallow water that has pooled in a very leaky aluminium utility boat. Next time you have a glass of wine rub the rim with a wet finger and you can see them on the surface of the wine; these Bessel Functions created on the surface of a drum give that essential music you can hear from a drummer in a rock band!!
