Eratosthenes, the director of the Alexandrian Library, is best known for calculating the Earth's circumference. He measured the angle of the sun's rays at noon in two different locations in Egypt—Alexandria and Syene—during the summer solstice. By using the distance between these two locations and the angles, he estimated the Earth's circumference to be about 39,375 kilometers (24,662 miles), a remarkably accurate figure for his time. This calculation laid the groundwork for future geographic and astronomical studies.

What scientific measurement did Eratosthenes the director of the Alexandrian library make?

Eratosthenes, the director of the Alexandrian library, is best known for calculating the Earth's circumference. He accomplished this by measuring the angle of the sun's rays at noon in two different locations in Egypt—Alexandria and Syene—during the summer solstice. By knowing the distance between the two cities and applying basic geometry, he estimated the Earth's circumference to be about 39,375 kilometers (24,662 miles), remarkably close to modern measurements. This achievement demonstrated the use of scientific reasoning and measurement in understanding the world.
