The Dzhanibekov Effect: A Fascinating Phenomenon Revealed

TLDRThe Dzhanibekov Effect, also known as the tennis racket theorem or intermediate axis theorem, is a mesmerizing phenomenon in physics. It involves the flipping motion of objects with varying moments of inertia. This effect was discovered by cosmonaut Vladimir Dzhanibekov and was kept a secret for 10 years. Despite its complexity, mathematician Terry Tao provided an intuitive explanation for this phenomenon. The Earth will not flip over due to its stable rotation about the axis with the maximum moment of inertia.
