spherics
Definition
- Noun (plural in form, used with a singular verb):
- The branch of geometry and trigonometry dealing with the properties of figures on the surface of a sphere: "spherics" refers to the mathematical study of spherical surfaces, including spherical geometry and spherical trigonometry. This field is concerned with points, lines, angles, and shapes on a sphere, rather than on a flat plane.
Usage Examples
- (The study of spherical geometry and trigonometry.)
- (The branch of mathematics applied to global measurements.)
Advanced Usage
"Spherics" in navigation: Historically, spherics was crucial for celestial navigation, allowing sailors to determine their position using stars.
- The captain relied on spherics to plot a course across the ocean. (He used spherical geometry to navigate.)
"Spherics" in astronomy: It is used to model the positions of celestial bodies on the celestial sphere.
- Astronomers apply spherics to predict planetary movements. (Spherical trigonometry helps calculate orbits.)
Variants and Related Words
Spherical (adj): having the shape of a sphere; relating to a sphere.
- The Earth is approximately spherical. (Round like a ball.)
Sphericity (n): the quality of being spherical.
- The sphericity of a drop of water is due to surface tension. (Its roundness.)
Spheroid (n): a shape that is nearly spherical but not perfectly round.
- Many planets are spheroids, flattened at the poles. (Oblate spheres.)
Synonyms
- Spherical geometry: the specific branch of mathematics focusing on figures on a sphere.
- Spherical trigonometry: a subfield of spherics dealing with triangles on a sphere.
Related Idioms
- None commonly found for "spherics" as a specialized term. However, the concept appears in the idiom:
- "On the sphere": referring to calculations or measurements made on a spherical surface.
- Navigators work on the sphere, not on a flat map. (They use spherical geometry.)
