Sobre aquest recurs...
A common misconception is that explorers like Columbus sailed to sea to prove that the earth is not flat. It has been known for thousands of years that not only is the earth NOT flat, but its circumference (the distance around) was well known. This simple experiment will repeat what was done more than 2,000 years ago by Eratosthenes and Posidonius.
