Will Earth Suddenly Flip Its Axis? The Tennis Racket Theorem
Usually, scientific topics have very strange names that might not be so funny or attractive, but this isn’t the case of the Tennis Racket Theorem, also known as the intermediate axis theorem.
This subject is strictly linked to a very weird event a Russian Cosmonaut called Vladimir Dzanibekhov observed while in space in 1985.
By removing a screw in the orbiting station during an experiment, he made it turn around an axis, but suddenly the bolt started to change the direction of rotation by itself, without any external help. He was really surprised, and the event took its name after the scientist: the Dzanibekhov Effect.
But what is the link with the Tennis racket Theorem? Have you ever tried to flip a phone or a racket? Isn’t there something really strange and inexplicable? Have you noticed it?
Well, if not, this video will introduce you to the bizarre behavior of rotating objects.
Did you know that the flipping of a little bolt was able to scare scientists to death, suggesting a possible ending of human life on Earth?
