In 570 BC, the famous mathematician Pythagoras (best known for the Pythagorean Theorem for finding the values of a right triangle) theorized that the Earth was round. At the time this was pretty radical thinking. However, given evidence such as the curved horizon of the ocean, the fact that a sphere is the most stable geometric form, and the clearly observable shape of the shadow cast by the Earth on the Moon during a lunar eclipse (seeing is believing), the scientific community began to take note. It was not until Columbus' famous expedition in 1492 that the then 2000-year-old theory was proven.
However...
Now Jack van Wijk of the Technical University of Eindhoven uses math again to show us iterations of what the world would look like if it were indeed flat. Enjoy this simple but beautiful animation.
