all relationships could be expressed in numbers. The essence of life and
understanding (thinking processes) were in numbers.
We often admire the architecture of the Egyptian pyramids. Although a
Greek, Pythagoras spent many years in Egypt, becoming acquainted with
Egyptian learning. When the Babylonians conquered Egypt, he was carried
away to Babylon, where he conversed with the Chaldean philosophers and
sages.
The Pythagorean brotherhood believed that thinking and reasoning was
derived from mathematical principles. This was the earliest development
of the mathematical system of logical inference known as geometry.
The most famous mathematical discovery was that the square of the hypotenuse
(the longest side in a right triangle) was equal to the sum of the squares
of the other two sides. This discovery is called the Pythagorean Theorem
today in his honor.
