This video explains the bizarre behavior of rotating bodies, which is that they tend to rotate around the axis with the maximum moment of inertia. This is because it is the state that has the least amount of energy dissipated. The Earth will not flip over, and most astronomical objects rotate around this axis.

**00:00:00**The Bizarre Behavior of Rotating Bodies video covers the Dzhanibekov effect, or the phenomenon where a rotating object, such as a tennis racket, makes a half turn around an axis that passes through its handle. The paper, "The Twisting Tennis Racket" was published in the Journal of Dynamics and Differential Equations in 1991, but makes no mention of the effect. The theory behind the effect is explained by discussing the three ways a tennis racket can be oriented about its three principal axes. Spins about the first or third axes are stable, while rotations about the second axis, the intermediate axis, are unstable and can't be stopped. This is the axis that the half twist is centered around.**00:05:00**In this video, Terry Tao, a renowned mathematician, explains the intermediate axis theorem, which is a mathematical principle that explains the behavior of rotating bodies. The theorem states that there is an axis in space along which the only forces acting on a rotating body are centripetal forces, which cause it to rotate uniformly. If the body is rotated around another axis, the centrifugal forces acting on the masses located away from the axis of rotation cause them to be accelerated and eventually to flip over. This principle is often used in physics to explain the behavior of rotating objects, such as tennis rackets and wings. Ten years ago, Soviet scientists discovered that the principle was classified and decided to keep it that way to keep the public from knowing about it.**00:10:00**This YouTube video explains the bizarre behavior of rotating bodies, which is that they tend to rotate around the axis with the maximum moment of inertia. This is usually the axis that achieves the minimum kinetic energy, and is usually the one with the largest moment of inertia. This is because it is the state that has the least amount of energy dissipated. The Earth will not flip over, and most astronomical objects rotate around this axis.
