**(ca. 320 – 275 BC)**

This pioneering dinosaur, who lived some 300 years before Jesus Christ, is the grandfather of geometry. Most of his works were lost; but those that survived indicated that he was the first person known to have used logical and rigorous proofs in solving theorems and conjectures. He was also the first to prove that prime numbers are infinitely many; as well as the first to differentiate axioms from theorems. After cutting his teeth with the works of Pythagoras and Eudoxus, Euclid established the first Maths Department at the University of Alexandria, in Egypt. He later authored his thirteen books, (collectively known as the *Elements*), which served as the world’s standard maths syllabus for more than 2000 years; and whose basis continues to form today’s High School curricula. Likewise, the Systems Definitions and the Geometrical Axioms, which he originated, have served the world for over 2200 years. All these consolidate his position as both the most famous mathematician and the greatest maths tutor. The fact that Euclid was “bred and buttered” in Egypt exposed him to the lofty schools of thoughts which were the world’s bests then. His analytical style is a reminder of the triumphs of the Egyptian Civilization. Simply put, if you are not dripping wet with Euclidean Geometry, you have not bathed in the ocean of mathematics.

Great contents from all parts of science. Means lots of power underneath this site.

Agreed. Euclid was a great dinosaur.

Wow! He holds some of the longest known math records. Thanks for the eye-opening info.
