Who was Eratosthenes?
Eratosthenes of Cyrene (now Libya) was a multifaceted mathematician, astronomer and geographer from the 3rd century BC. It is famous for the method of obtaining the list of prime numbers known as the Eratosthenes screen. He is also known for measuring the size of the Earth by observing the difference between the direction of the sun's rays indicated by the shadows between Alexandria and Silene (present-day Aswan).
