Greek mathematician and philosopher who formulated Pythagoras' theorem.
Much of Pythagoras' work concerned numbers, to which he assigned mystical properties. For example, he classified numbers into triangular ones (1, 3, 6, 10, ...), which can be represented as a triangular array, and square ones (1, 4, 9, 16, ...), which form squares. He also observed that any two adjacent triangular numbers added together form a square number (for example, 1 + 3 = 4; 3 + 6 = 9; 6 + 10 = 16).
