In 1865, James Clerk Maxwell referred to a key innovation in his work as "electric elasticity". This innovation was the idea that the electrostatic energy in a medium is the same as the elastic potential energy that results from the displacement of electric particles. Maxwell's work also included the idea that the velocity of waves in an elastic medium would be the same as the electromagnetic and electrostatic unit of electric charge, which is the speed of light.

In mathematics, a polynomial is a mathematical expression consisting of indeterminates (also called variables) and coefficients, that involves only the operations of addition, subtraction, multiplication and exponentiation to nonnegative integer powers, and has a finite number of terms.[1][2][3][4][5] An example of a polynomial of a single indeterminate x is x2 − 4x + 7. An example with three indeterminates is x3 + 2xyz2 − yz + 1.
Polynomials appear in many areas of mathematics and science. For example, they are used to form polynomial equations, which encode a wide range of problems, from elementary word problems to complicated scientific problems; they are used to define polynomial functions, which appear in settings ranging from basic chemistry and physics to economics and social science; and they are used in calculus and numerical analysis to approximate other functions. In advanced mathematics, polynomials are used to construct polynomial rings and algebraic varieties, which are central concepts in algebra and algebraic geometry.
