Eleytherios Argyropoulos

Eleftherios Argyropoulos was born in 1967 in Kalamata. From a young age, he showed an interest in mathematics and physics, and after graduating from high school, he was admitted to the National Technical University of Athens, where he began his research in mathematics. Between 1986 and 1997, he discovered 525 different proofs of the Pythagorean theorem. This achievement was recognized by the Guinness Book of World Records in June 1999. In 1986, at the age of 19, he designed and constructed three skateboard ramps using equations from analytical geometry, trigonometry, and statistical analysis. In September 2002, he completed his studies in mathematics and graduated from Northeastern University in Boston, USA, presenting three original mathematical papers. The first of these was a proof of Fermat's Last Theorem for the case of even exponents, based on the generating equations of Pythagorean triples. His second paper was a generalization of the Fermat-Torricelli point theorem for all regular polygons, rediscovering the theorem of mathematician Kiepert in a completely different way from the German mathematician. The third was the discovery of a new method for calculating determinants of square matrices, which is second in computational speed only to the upper or lower triangularization method of German mathematician Gauss. In addition to mathematics, he has been involved in sports and electronic music. He has composed three musical works titled "Marathon Runner," "The Light of Apollo," and "Pythagoras." He has run several marathons and ultramarathons, with the longest distance being the Alexandroupolis-Athens route (850 km), which he completed twice, in 2004 and 2005. In 1993, he covered 436.6 km on a skateboard in 36h:33':17" and has memorized the first 1,000 decimal places of the number π=3.14...
