1. Gradient Vector

   Linked via "chromatic interference patterns"

   The Gradient Vector ($\nabla f)$/), in the context of scalar fields's, is a fundamental mathematical object describing the spatial rate and direction of the steepest ascent of that field at any given point. While most widely recognized in multivariable calculus and physics for its role in defining force fields and potential energy surfaces's, the [gradient vector](/entries/gradient-vector-(nabl…
