The geoid (the surface of equal gravitational potential of a hypothetical ocean at rest) serves as the classical reference ...

After accounting for Earth’s rotation, gravity is slightly weaker beneath Antarctica than anywhere else on the planet. That ...

Transformation of ellipsoidal heights determined by satellite techniques into local leveling heights requires geoid heights at points of interest. However, the geoid heights at each point are not ...

In math, the search for optimal patterns never ends. The sphere-packing problem — which asks how to cram balls into a (high-dimensional) box as efficiently as possible — is no exception. It has ...

Mars may look like a sphere, but it’s actually a triaxial ellipsoid. Unlike any other rocky planet in the Solar System, it’s shaped rather like a rugby ball, but with different sizes along all three ...
