"The birth of Greek astronomy has been attributed to Thales of Miletus. Thales brought from Egypt a number of fundamental geometric principles. He was able to take what he learned, develop upon it, and put it to practical use for the Greeks. Another important contributor to the foundation of Greek geometry was Pythagoras. Pythagoras is credited with the discovery of the famous Pythagorean theorem which equates the sides of a right triangle. Pythagoras and his followers, the Pythagoreans, developed and proved a few significant theorems and may have discovered the existence of irrational numbers." from Foundations of Greek Geometry, Michael Tirabassi.



Note: Pythagorean Theorem was first developed in Mesopotamia between 1900 and 1800 BC.  It and many other mathematical principles of  used by surveyors and engineers in the Middle East were consolidated by the Greeks.  The Greeks were the first to have academies and schools much like today's universities.
