So much of what we say about Columbus is either wholly untrue or greatly exaggerated. Here are a few of the top offenders. 1. Columbus set out to prove the world was round. If he did, he was about 2,000 years too late. Ancient Greek mathematicians had already proven that the Earth was round, not flat. Pythagoras in the sixth century B.C.E. was one of the originators of the idea.
The simplest and most convincing proof that the Earth's is round is to examine a photo of our planet taken from space or to orbit it in the space shuttle. There can be no doubt from such evidence that the Earth is round, or more correctly, a sphere.. The word round refers to a circular shape, like the shape of a quarter when held flat in your hand. The proper term to describe the Earth's shape is spherical. A sphere appears round when viewed from any direction in space. It's okay to use the term round to refer to the shape of the Earth, so long as you're aware of this distinction.
