Homo ad Quadratum

Actually, perfect *squares* are extremely rare in nature. *Squares* are human constructs.

We imagine Pythagoras and the Greek philosophers drawing their *squares* in the sand, dividing the sides equally, connecting the divisions, and counting the resulting smaller *squares* to develop the concept of a number multiplied by itself. The concept is probably much older. Both the Babylonians and the Egyptians had methods for calculating volume based on *squared* empirical approximations of Pi.

It is easy to imagine our forebears drawing a *square* around a circle to get the notion that the area of the circle varied with the radius *squared*. If that were the end of it one could dismiss it as the artifact of a practical approach, but these *squares* keep coming back.

Newton’s laws of gravitation vary the *square* of distance. Gravity? We’re a long way from geometric lines in the sand now.

E=MC*squared* is Einstein’s formula for the relationship (relativity) of mass and energy. The speed of light *squared*?

Yagahhdabekiddnme! Why not the cube root or something…
