"Spheres" can refer to various concepts depending on the context. Here are a few interpretations: 1. **Mathematics**: In geometry, a sphere is a perfectly round three-dimensional shape, every point of which is equidistant from a central point. It's defined by its radius or diameter. 2. **Physics**: In physics, spheres can be used to model various phenomena, like gravitational fields or fluid dynamics, where spherical symmetry simplifies calculations.
