Eratosthenes is highly praised for this great accomplishment because he did not have any modern tools that we have today and was able to calculate the Earth’s circumference, all while never leaving Egypt.

Archimedes was a Greek Mathematician. He was born around 287 B.C. probably in the town of Syracuse, Italy, and he died I 212 B.C., also in Syracuse. Archimedes invented the “Archimedes Screw” and determined how large pi was, among numerous other accomplishments. Information will be presented on Archimedes' family life, scientific investigations, and how his discoveries are used today. Archimedes was an intriguing man, who harbored many skills. Archimedes was born about 287B.C. to Phidias an astronomer
