Eratosthenes, a Greek mathematician and astronomer, significantly impacted the world through his pioneering work in geography and mathematics. He accurately calculated the Earth's circumference using measurements of the angles of shadows cast by the sun at different locations, demonstrating the Earth's spherical shape. His method of estimating distances and the concept of latitude and longitude laid foundational principles for cartography and navigation. Additionally, his work influenced later scholars and explorers, contributing to advancements in science and knowledge during the Renaissance and beyond.

What are the 3 things named after Eratosthenes?

Eratosthenes is known for several significant contributions, and three notable things named after him include the "Eratosthenes sieve," an ancient algorithm for finding prime numbers, the "Eratosthenes measure," which refers to his method of calculating the Earth's circumference, and the "Eratosthenes crater," a large impact crater on the Moon named in his honor. His work laid foundational principles in mathematics, geography, and astronomy.


What was the contribution of Eratosthenes?

Eratosthenes is a Greek Philosopher whom ideas were way out of his time. He discovered two important things about the earth, one in which is that the world is shape like a sphere in which we know today because of satellite imagery but in that time they did not have the the thought nor the technology.The next thing he discovered is the Earth's circumference which was only off by 185 miles. Another important fact is that Eratosthenes was in charge of the library in the city of Alexandria.


What interesting things happend in Eratosthenes life?

Eratosthenes, a Greek mathematician, astronomer, and geographer, is best known for calculating the Earth's circumference with remarkable accuracy using shadows cast by the sun at different locations. He also invented the sieve of Eratosthenes, an efficient algorithm for finding prime numbers. As the chief librarian at the Library of Alexandria, he contributed significantly to the preservation and organization of knowledge in the ancient world. Additionally, Eratosthenes was among the first to use the term "geography" and made important advancements in understanding the Earth's tilt and its impact on climate.
