The Earth curved 7 degrees at a distance of 515 miles.
The Earth would curve 1 degree at a distance of:
And because the Earth is a sphere, the total curvature angle is 360 degrees.
The Earth would curve 360 degrees at a distance of:
It is Circumference of the Earth.
While the actual circumference is 24900 miles.
5. This may be the first calculation of the circumference of the earth ever made! It...
2. One assumption that Eratosthenes made was that the earth was a perfect sphere. What are 5 other assumptions critical to this calculation? Eratosthenes was a Greek mathematician who lived 276-194 BC. At summer solstice he waited until noon, when the sun was directly overhead in Aswan. He placed a gnomon (basically a stick) at the bottom of the well at 90° to the ground, and noticed that it cast no shadow. Then at the same time he had others...
Eratosthenes measured the circumference of the Earth by noting that the Sun is at an angle of 6o south of the vertical in Aleandria at the same time of day and year that it is directly overhead in Syene, 400 km directly south of Alexandria. Find the circumference of the Earth from these data. (arc length: s=Rtheta for theta in radians) and C=R2pie.

2. Aristarchus of Samos (310-230 BC) was a Greek mathematician and astronomer who first proposed a heliocentric model for our solar system, thousands of years before Copernicus. His ideas were based on his calculations of the sires of the Earth, Moon, and Sun. The approach below is a simplified version of his approach that includes knowledge of the work of contemporaries, such as the calculation of the Earth's radius by Eratosthenes of Cyrene (276-194 BC). (Note: We showed in class...
