Field (physics)
COMMON PHYSICS TERM FOR A PHYSICAL QUANTITY, REPRESENTED BY A NUMBER OR TENSOR, THAT HAS A VALUE FOR EACH POINT IN SPACE-TIME
Field theory (physics); Internal group; Physical field; Classical field; Field physics; Relativistic field theory; Spatial field
In physics, a field is a physical quantity, represented by a scalar, vector, or tensor, that has a value for each point in space and time. For example, on a weather map, the surface temperature is described by assigning a number to each point on the map; the temperature can be considered at a certain point in time or over some interval of time, to study the dynamics of temperature change.
