So Eratosthenes hired a few bematists to pace out the distance. A bematist was a professional surveyor who’d been trained to walk in steps of equal length, and also not to deviate to the left or right – to simply to walk in a straight line. Luckily, back then, there were people called bematists. How do we go about proving that MICHELLE THALLER: Thats a hard thing for me to. The second problem was measuring the distance. BILL NYE: Is the earth flat or round Its round, okay. No biggie that would introduce a relatively small error. ![]() First, Alexandria was not exactly north of Syene, but about 20 degrees off to one side – to the west. ![]() A painting depicting Eratosthenes teaching at the Library of Alexandria. If Alexandria was exactly due north of Syene, all Eratosthenes had to do was measure the distance between the two places, multiply that distance by 50 and bingo! He had the circumference of planet Earth. (Back then, scientists were pretty good at basic geometry.) However, if the flat-Earth theory were true, millions of people perpendicular to the sun-moon lineup would see a fully eclipsed first- or last-quarter moon. He found that his stick cast a shadow of about 7.2 degrees, roughly one fiftieth of a complete circle of 360 degrees. So, the following year, on that day, at the same time, he measured the shadow at his location in Alexandria (about 850km away, or a month’s easy walk). ![]()
