Sphericity

Sphericity is a geometric measure that describes how closely the shape of an object resembles that of a perfect sphere. It quantitatively assesses the roundness of a shape in three-dimensional space. The concept is often used in various fields, including statistics, physical sciences, and engineering. In a mathematical context, sphericity can be defined as the ratio of the surface area of a sphere with the same volume as the object to the surface area of the object itself.
