Identify the Contribution of Scientists; Interpret Written Presentations Write a paragraph identifying how the observations of Eratosthenes described in the excerpt below led to his notable contribution to science. Consider what Eratosthenes is known to have discovered and how his findings are still relevant today.
“Eratosthenes used Aristotle's idea that, if the Earth was round, distant stars in the night sky would appear at different positions to observers at different latitudes. Eratosthenes knew that on the first day of summer, the Sun passed directly overhead at Syene, Egypt. At midday of the same day, he measured the angular displacement of the Sun from overhead at the city of Alexandria—5000 stadia away from Syene.”
