“No wonder they call it a circle—it is so round! Notice how the inside comes precisely to the line and not one whit farther. And how the outside can’t possibly get in. No corners is one of the principle things about a circle. An oval has no corners, too, but they are not nearly as no corners as a circle has. Circles are nice because we can go around in them. Hardly anybody ever goes around in squares. Ever single place on the outside of a circle is the same distance from the centre as every other place. You can’t say that about a parallelepiped.” — Colonel Stoopnagle
