round · shape
a thing whose boundary is the same distance from its center in every direction
Examples
- The Earth's equatorial bulge makes its equatorial diameter 43 kilometers greater than its polar diameter, yet it remains approximately round due to gravity. astronomy
- A soap bubble in still air forms a nearly perfect sphere, minimizing surface tension across its boundary. physics
- The Pantheon's dome in Rome maintains a round interior space, defined by its coffered concrete curvature converging at a central oculus. architecture
Emergence
through: the center and directions define reference points from which the boundary maintains a constant distance in all directions
- constant radial distance
- symmetry around center
- uniform curvature
