Square–cube law The square–cube law (or cube–square law) is a mathematical principle, applied in a variety of scientific fields, which describes the relationship between the volume and the area as a shape's size increases or decreases. It was first described in 1638 by Galileo Galilei in his "Two New Sciences" as the "...ratio of two volumes is greater than the ratio of their surfaces".

The Wave equation is sometimes referred to as d'Alembert's equation.
