In memory of Sofya Kovalevskaya.
In 1874 Sofya presented three papers—on partial differential equations, on the dynamics of Saturn's rings, and on elliptic integrals—to the University of Göttingen as her doctoral dissertation. This earned her a doctorate in mathematics summa cum laude
In 1888 she won the Prix Bordin of the French Academy of Science, for her work "Problem of rigid body rotation around fixed point". Her submission featured the celebrated discovery of what is now known as the "Kovalevskaya top"
The cosmic vibe of rigid bodies spinning around fixed points:
