What is the tennis racket theorem?
In: 3
It’s about how an object that has three different length axis, will behave when it is spun around an axis.
When spun around the longest axis, the spin is stable and it will just spin. When spun around the shortest axis, the spin is also stable and it will just spin as well.
But when the spin is around the third, intermediate axis, then the spin is not stable and you get chaotic behaviour. The math for it isn’t all that simple, but in essence when something is spun around the intermediate axis, any disturbance in movement around the two other axis, gets amplified rather than dampened (as when spinning around the longest or shortest axis) and you get very unstable, chaotic behaviour instead.
