spherethings

Spherethings is an informal term used to describe objects that are spherical in shape or exhibit spherical symmetry. It is not a formal scientific category, but appears in design discourse, science fiction, and general science writing as a convenient label for round, ball-like forms or for items whose properties are approximately the same in all directions.

In geometry, a perfect spherething would be a sphere: a figure in which every point on the surface is equidistant from a central point. The sphere has surface area 4πr^2 and volume 4/3πr^3. In physics and engineering, spherical symmetry means properties are unchanged under rotations about the center.

Real-world examples of spherethings include sports balls, droplets and bubbles, microscopic nanoparticles such as fullerenes, and certain planetary models. In manufacturing and optics, spherical elements are used in bearings, lenses, and decorative objects. In culture and art, spherethings can symbolize completeness, unity, or wholeness due to their uniform curvature.

Usage varies by author and field, reflecting a descriptive rather than technical status. The term is most helpful as shorthand when the precise category is less important than the spherical form itself. See also sphere, ball, spherical geometry.
