A field is a physical quantity that has a value at every point in space and time. In modern physics, fields provide the fundamental description of nature, underlying both particles and interactions.
A field assigns values (such as strength or direction) to every point in space.
Description
Fields describe how physical quantities vary across space and time. Classical examples include electric and gravitational fields, while in quantum theory fields are the basis for describing particles.
Properties
- defined at every point in space and time
- can carry energy and momentum
- underlying description of physical systems
