What is the contribution of Eratosthenes in mathematics?
He has written works on geography, philosophy, history, astronomy, mathematics, and literary criticism. One of Eratosthenes’ contributions to mathematics was his measurement of the Earth. He calculated the circumference of the Earth to be about 252,000 stadi which is equal to about 24,662 miles.
What did Eratosthenes discover in mathematics?
One of the most remarkable things done by Eratosthenes included his effort to calculate the Earth’s circumference without leaving the comfortable perimeters of Egypt. Eratosthenes also discovered an algorithm to determine prime numbers which is known as the Sieve of Eratosthenes. He also invented the armillary sphere.
What two things is Eratosthenes most famous for?
We know him best for two important achievements: producing an accurate estimate of how big Earth is; and devising a method to find prime numbers. Unfortunately, other than a few scraps, little remains of Eratosthenes’ original work.
How did Eratosthenes contribute to oceanography?
Besides navigation, Eratosthenes also measured the Earth’s circumference fairly well. Research into physical oceanography included Strabo, who observed volcanic activity and concluded that land was not totally static. He also realized that streams eroded continents and deposited sediments into the ocean.
What is the contributions of Eratosthenes?
Eratosthenes may have been the first to use the word geography. He invented a system of longitude and latitude and made a map of the known world. He also designed a system for finding prime numbers — whole numbers that can only be divided by themselves or by the number 1.
How did Eratosthenes change the world?
Besides figuring out the size of the Earth, Eratosthenes made several other important inventions and discoveries. He invented an easy method for finding out prime numbers. That mathematical method is now called the Sieve of Eratosthenes. He made a map of the “whole world”.
Did Eratosthenes get married?
Eratosthenes was born in 276 B.C. in the city of Cyrene which is in the modern-day country of Libya. He studied for a few years in Athens. Some people believe that Eratosthenes starved himself to death on purpose after going blind. He never married.
Who was Eratosthenes and major contributions?
Eratosthenes, in full Eratosthenes of Cyrene, (born c. 276 bce, Cyrene, Libya—died c. 194 bce, Alexandria, Egypt), Greek scientific writer, astronomer, and poet, who made the first measurement of the size of Earth for which any details are known.
What was Eratosthenes impact?
Eratosthenes made many other major contributions to the progress of science. He worked out a calendar that included leap years, and he laid the foundations of a systematic chronography of the world when he tried to give the dates of literary and political events from the time of the siege of Troy.
What is the contribution of Eratosthenes?
Eratosthenes made major contributions to geography. He sketched, quite accurately, the route of the Nile to Khartoum, showing the two Ethiopian tributaries. He also suggested that lakes were the source of the river.
