In mathematics and physics, a scalar field associates a scalar value to every point in a space.
Description
The scalar may either be a mathematical number or a physical quantity.
Scalar fields are the subject of scalar field theory.
Coordinate independence
Scalar fields are required to be coordinate-independent, meaning that any two observers using the same units will agree on the value of the scalar field at the same absolute point in space (or spacetime) regardless of their respective points of origin.
Examples
Examples used in physics include:
- The temperature distribution throughout space
- The pressure distribution in a fluid
- Spin-zero quantum fields, such as the Higgs field
