Pythagoras Born on the Greek island of Samos in about 570 bce, Pythagoras became a keen MATHEMATICIAN. He is best known for his theorem of right-angled triangles, which states that the square of the length of the hypotenuse (longest side of a triangle) is equal to the sum of the squares of the lengths of the other two sides.
Empedocles In the 5th century bce, poet and philosopher Empedocles proposed a theory that every object is a mixture of FOUR ELEMENTS of matter – earth, air, fire, and water. He thought that love and strife, or disagreement, filled the space between these elements, controlling and balancing them.
