A Fast Method for Solving the Helmholtz Equation Based on
... One way to solve partial differential equations numerically is to use finite difference methods, in which the derivatives are approximated by the differences of the neighboring points on a grid [29]. When a PDE is time dependent, one can discretize it first in space (semidiscretization) and then use ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
