He is considered to be the first pure mathematician.
He was born in 569 BC to a merchant from Tyre. As a child he was very well educated.
Little is known about his mathematical acheivements because he and his society followed a code of secrecy.
Developed many theorems still widely used today in mathematics including his most famous theorem : The Pythagorean Theorem which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides or simply:
Also contributed to the field of Astronomy with his teachings that stated that the Earth was the center of the universe and that the planet Venus, like the sun, orbited the Earth.
Many of Pythagoras observations on planetary and star movement are still used today.
He is also credited with developing a mathematical system that expresses extremely large numbers expontentially.
In addition to his many mathematical treatises, he came up with Archimedes Principle which states that an object placed in fluid pushes up with a force equal to the mass of displaced fluid.
One of his greatest inventions is known as Archimedes’ Screw which is a device shaped like a cylinder with a continuous screw inside it. This device was used to raise water, sand and soil. It’s applications are still used to this day in irrigation and drainage.
Euclid of Alexandria 325-265 B.C.
Born in Tyre, Egygt there is little known about his life.
His most famous mathematical work was the treatise he wrote called Elements which consisted of thirteen books.
