The Square
The one shape it will not become.
For more than two thousand years, people tried to draw a square with exactly the area of a circle, using only a compass and a straightedge. No measuring. No guessing.
The circle keeps its area. It only declines to be squared.
In 1882, Ferdinand von Lindemann proved it cannot be done. The reason is π itself: it is not only endless, it is a kind of number those two tools can never build.
The circle keeps its area. It only declines to be squared.
A 9-inch round pan holds 63.6 square inches. The square that holds exactly as much is 7.98 inches on a side.
