Physics an increase or decrease in the magnitude of a property (e.g., temperature, pressure, or concentration) observed in passing from one point or moment to another. ∎  the rate of such a change. ∎ Math. the vector formed by the operator ƍ acting on a scalar function at a given point in a scalar field.
