The equations of motion

I have started the Dzhanibekov effect series with quaternions, but that is because of my personal attraction to quaternions. Some years ago I coauthored a paper on Quaternions and Monopoles. The monopoles there are the exotic “magnetic monopoles” that are lake fairies. Some physicist say they have seen them in the woods, but the majority of physicists take it as a joke. Quaternions are also somewhat exotic. I do not know if magnetic monopoles have any relation to Dzhanibekov effect, though, in fact they may have one – but that is for the physics of the future. For the physics of today, for the physics of a cosmic spinning and flipping nut, we need the physics of a rigid body. That is part of classical mechanics.

According to Wikipedia

In physics, a rigid body is an idealization of a solid body in which deformation is neglected. In other words, the distance between any two given points of a rigid body remains constant in time regardless of external forces exerted on it.

I should say that the concept of a rigid body becomes somewhat iffy when we want to take into account what Albert Einstein taught us about first special, and then general relativity. I did not see yet a satisfactory relativistic theory of Dzhanibekov effect. What I know is that some physicists trying to sell their fantastic ideas to the investors (example G. Shipov) try to relate Dzhanibekov effect to “torsion fields” and “4D gyroscopes“. I have published some comments on this subject in International Journal of Unconventional Science. “Comments on Chapter 5 of G. I. Shipov’s “A Theory of Physical Vacuum”. Part I” is available in English. The second part, dealing with Shipov’s “4D gyroscopes” is for now available only in Russian, but it will be translated into English soon.
