Euclid of Megara and Alexandria

Euclid of Megara and Alexandria

It is widely believed that Euclid studied under Aristotle. He later founded the school of mathematics at the university of Alexandria. He was also first to discover that there are probably an infinite amount of prime numbers and he created Euclid's algorithm for computing Greatest Common Divisor. He introduced the Mersenne primes and observed that (M²+M)/2 is always perfect

"The laws of nature are but the mathematical thoughts of God,"- Euclid

His famous writings  consist of many important theorems, most were inspired by the people before him like Hippocrates or Exodus. Some of his books include: The Division of the scale, The Optics and The Elements. Sadly most of his masterpieces were lost in history or ruined but The Elements was used as a textbook for almost 2000 years and is still the basis of almost all high school geometry today.
