Ehrenfest paradox

Ehrenfest paradox is a strange idea in physics that says that the laws of motion don't always work the same way when you look at them in a very small scale. Imagine a round table and a person who is spinning around it really fast. If you look at them from far away, it looks like the person is spinning around in a circle, but if you look closely, the person is actually following a curved path. This is because the laws of motion work differently in the microscopic world than they do in the macroscopic world. In the small scale, the laws of motion don't work like they do in the large scale, so the path followed by the spinning person isn't quite in a circle.
