GIMPS has discovered a new largest known prime number: 2^{82589933}1 (24,862,048 digits) Euclid (pronounced YOO klihd) was a Greek mathematician who lived approximately 330270 B.C. Euclid compiled and systematically arranged the geometry and number theory of his day into the famous text "Elements." This text, used in schools for about 2000 years, earned him the name "the father of geometry." Even today, the geometries which do not satisify the fifth of Euclids "common notions" (now called axioms or postulates) are called nonEuclidean geometries. When the Egyptian ruler Ptolemy (reports Greek philosopher Proclus ) asked if there was a shorter way to the study of geometry than the Elements, Euclid told the Pharaoh that "there is no royal road to geometry." Little is known of Euclid's life. Proclus wrote (c. 350 AD) that Euclid lived during the reign of Ptolemy and founded the first school of mathematics in Alexandriathe site of the most impressive library of ancient times (with perhaps as many as 700,000 volumes). He wrote books on other subjects such as optics and conic sections, but most of them are now lost.
