what is the importance of constants ?
Answers
Answer:
The number and status of constants that physicists use reflect the evolution of theories in physics, by making explicit the unit of certain physical phenomena. “By establishing bridges between quantities previously deemed incommensurable, constants make possible the emergence of new concepts,” remarks Uzan.

Explanation:
A physical constant, sometimes fundamental physical constant or universal constant, is a physical quantity that is generally believed to be both universal in nature and have constant value in time. It is contrasted with a mathematical constant, which has a fixed numerical value, but does not directly involve any physical measurement.
There are many physical constants in science, some of the most widely recognized being the speed of light in vacuum c, the gravitational constant G, the Planck constant h, the electric constant ε0, and the elementary charge e. Physical constants can take many dimensional forms: the speed of light signifies a maximum speed for any object and its dimension is length divided by time; while the fine-structure constant α, which characterizes the strength of the electromagnetic interaction, is dimensionless.
