Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external crust, which may cause minute changes in Earth’s rotation and subtly affect the ...
A ring or sphere could, apparently, be stable if surrounded by the right sizes and gravities of other stars.
The nine chapters deal respectively with preliminary ideas, trihedral angles, skew quadrilaterals, tetrahedra, transversals, oblique cones, spheres, inversion, and recent geometry of the tetrahedron.
