A Mathematical Modeling Team at the Department of Theoretical Mechanics of the Ural Federal University (headed by Natalia E. Misura & Euigene A. Mityushov) was the first to present (in 2018) an “exact” animation of the critical torque free motion of a rigid motion, which ought not be confused with any other (non-critical) motion in its “vicinity”. Such critical motion is fully clarified in a joint paper of four authors, where an axis (rightfully named the Galois axis) is shown to rotate uniformly whether or not a “reversal” (in two distinct “mirror-symmetric” ways!) of the intermediate axis of inertia occurs. The joint paper was preceded by a short talk on November 09, 2017 (in Russian), and succeeded by a presentation (where the Galois axis was brought to a shining light) on January 29, 2019. The Galois axis made its debut to a textbook in Кватернионные модели в кинематике и динамике твердого тела, 2020: 88.
有限会社 大平技研 Ohira Tech is the first company in the world to implement (a pilot version of) the rotating celestial sphere. The invention is coauthored with the president of the company Takayuki Ohira 貴之 大平 and its public presentation is scheduled for November 2021 (yet to be additionally specified and announced) in Saint Petersburg, Russia. Patent № 2730227.
