tori

Rings in geometry

Tori is the plural of torus, a doughnut-shaped geometric surface formed by rotating a circle around an axis.

The shape appears in mathematics, physics, and design: The magnetic field confined the plasma within nested tori.

In architecture, a torus is a convex molding with a semicircular profile, making tori a term for such decorative elements on column bases.
