sférických

Sférických is a Czech adjective meaning "spherical." It is used to describe objects or concepts that are shaped like a sphere, a perfectly round geometrical object in three-dimensional space. This shape is characterized by all points on its surface being equidistant from its center.

In mathematics, sférických refers to geometric properties related to spheres. This can include calculations of volume, surface area, or distances on the surface of a sphere, often encountered in fields like geometry, trigonometry, and calculus. For example, the area of a sférických surface is given by the formula 4πr², where r is the radius.

The term is also used in astronomy to describe celestial bodies that approximate a spherical shape, such as planets, moons, and stars, due to the force of gravity. In physics, it can describe phenomena or objects with rotational symmetry around a central point. Even in everyday language, sférických objects are common, from balls and marbles to certain types of bubbles. The concept of sphericity is fundamental in many scientific and technical disciplines.
