- The earth is a flat disk?
- Hush! It;s shaped like an oyster
- No! It's shaped like a cylinder!
- The Earth's shape is round. I believe that the sphere is the perfect geometric shape and the gods would only create a perfect world.
- The Earthis really spherical because of these observations I had....
- Back then, about 600-800 B.C., many people believed on different shapes of the Earth...
- When there is an eclipse, the moon always has a curved shadow casted by the eart...meaning that the Earth has curves because it is round.
- On a significant day around 500 B.C., Pythagoras, a philosopher and mathematician, made an announcement expressing his belief that the Earth possesses a round shape.
- The stars are constantly in different positions depending a person's location.
- Not only the earth is circular in shape, but also that it is a sphere of no great size: or otherwise, the effect of so slight change o place wouldn't be quickly apparent.
- Over time...Aristotle, a renowned philosopher, diligently gathered evidence that strongly supported the notion of Earth's roundness. In fact, he specifically argued that the Earth is a sphere.
- One of the evidences was observed from eclipses....
- He added too that the stars that are overhead are significantly changed by a very small change of position to south or north, and the stars seen are different, as one moves north or south.
- Years later.....Another philosopher, Eratosthenes, further proved that the earth is round and determined it's circumference with the use of a stick and the sun.
- Hmm, the stick casted a shadow here but on the last place I went to, it doesn't. I can determine the circumference of the Earth with these evidences.
