Task 1. Task 1 Diagram. Task 2 link. Task 2 video. Task 3. Task 4. Eratosthenes. It can be said that Eratosthenes is most widely known as a famous Greek mathematician. What most people probably do not know is that Eratosthenes is not only a famous mathematician but also a well known geographer, astronomer and historian. Before I get into a few of his accomplishments, let me tell you a little about his personal history. Eratosthenes was born in Cyrene, Greece, which is now known as Libya, in North Africa, in 276 B.C.E.. It is believed that he starved himself to death in 195 B.C.E. due to the fact that he became blind and could no longer work. As a young man, Eratosthenes studied in Athens. One of his major accomplishments in mathematics is his creation of a sieve that determines prime numbers up to any given limit.

Eratosthenes is also known for his achievement in astronomy. There is still more. Eratosthenes biography. Eratosthenes was born in Cyrene which is now in Libya in North Africa. His teachers included the scholar Lysanias of Cyrene and the philosopher Ariston of Chios who had studied under Zeno, the founder of the Stoic school of philosophy. Eratosthenes also studied under the poet and scholar Callimachus who had also been born in Cyrene. Eratosthenes then spent some years studying in Athens. The library at Alexandria was planned by Ptolemy I Soter and the project came to fruition under his son Ptolemy II Philadelphus. [Eratosthenes] was, indeed, recognised by his contemporaries as a man of great distinction in all branches of knowledge, though in each subject he just fell short of the highest place. Certainly this is a harsh nickname to give to a man whose accomplishments in many different areas are remembered today not only as historically important but, remarkably in many cases, still providing a basis for modern scientific methods. a : x = x : y = y : b.

What did Eratosthenes of Cyrene contribute to astronomy in ancient Greece? | eNotes. Eratosthenes of Cyrene (276 BC-194 BC) is a famous Greek mathematician, astronomer, geographer, artist and historian. He was from the land of Cyrene, Greece which is now part of the present Libya. He is known as the first person to measure the circumference of the earth as accurately as possible. With limited knowledge in astronomy and resources, Eratosthenes measured the circumference of the earth using the rays of the sun and the shadow it shed at Cyrene. He believed at summer solstice, the sun is directly shining at Egypt and measure the angle of elevation to be 1/50th of a circle or approximately 7 degrees. He also measured that the earth is tilted in the axis at around 23.5 degrees. Archimedes. Archimedes of Syracuse (c.287 BC - c. 212 BC) was an ancient Greek mathematician, physicist and engineer.

Although little is known about his life, he is regarded as one of the most important scientists in classical antiquity. In addition to making important discoveries in the field of mathematics and geometry, he is credited with producing machines that were well ahead of their time. The Ancient Roman historians showed a strong interest in Archimedes and wrote several biographies relating to his life and works, while the few copies of his treatises that survived through the Middle Ages were a major influence on scientists during the Renaissance. Archimedes produced the first known summation of an infinite series with a method that is still used in the area of calculus today. Archimedes was a famous mathematician whose theorems and philosophies became world known. He gained a reputation in his own time which few other mathematicians of this period achieved.

Click for a discussion of certain omissions. Please send me e-mail if you believe there's a major flaw in my rankings (or an error in any of the biographies). Obviously the relative ranks of, say Fibonacci and Ramanujan, will never satisfy everyone since the reasons for their "greatness" are different. I'm sure I've overlooked great mathematicians who obviously belong on this list. Please e-mail and tell me! Following are the top mathematicians in chronological (birth-year) order.

Geocentrism vs. Archimedes - Hellenistic Mathematics. Another Greek mathematician who studied at Alexandria in the 3rd Century BCE was Archimedes, although he was born, died and lived most of his life in Syracuse, Sicily (a Hellenic Greek colony in Magna Graecia). Little is known for sure of his life, and many of the stories and anecdotes about him were written long after his death by the historians of ancient Rome. Also an engineer, inventor and astronomer, Archimedes was best known throughout most of history for his military innovations like his siege engines and mirrors to harness and focus the power of the sun, as well as levers, pulleys and pumps (including the famous screw pump known as Archimedesâ€™ Screw, which is still used today in some parts of the world for irrigation). But his true love was pure mathematics, and the discovery in 1906 of previously unknown works, referred to as the "Archimedes Palimpsest", has provided new insights into how he obtained his mathematical results.
