Eleftherios Argyropoulos was born in Kalamata on April 1, 1967. Since his early high school years he showed great interest in mathematics and physics. Immediately after graduating from high school, he began research in mathematics. In 1986, when he was just 19 years old, he designed and constructed three skateboard ramps, using Analytic Geometry equations, Trigonometry and Physics. Since June of the year 1986 to December 1997, while working up to the last theorem of French mathematician Fermat, discovered 525 different proofs of the Pythagorean theorem and in 2002 completed his studies at Northeastern University in Boston delivering a dissertation of three important mathematical papers on the theory of numbers, linear algebra and Euclidean geometry. This work was the proof of Fermat's last theorem for the case of the even exponents, the discovery of a new formula for calculating determinants of square matrices and the generalization of the theorem of the point of Fermat - Torricelli. Also, during the same year, he completed and delivered at Northeastern University a paper about Physics, where he developed a new method of placing a satellite into Earth orbit. Since 1983, he studies the mathematical structure and lexarithmic intelligence of the Hellenic language and in the period 1998 - 2017 he has authored ten books on the subject, of which one is in English. Eleftherios has also interest to long distance running and the composition of electronic music. He has composed three musical works (CD) with titles "Marathon runner" (1994), "The Light of Apollo" (2001) and "Pythagoras" (2005). Moreover, he has completed more than 40 marathons and 20 ultra-marathons. The longest distance he has run without stop, is 170 km from Delphi to Athens on 10th of April 1998 in the time of 20 hours, 33 minutes and 14 seconds, while he has also run three times the distance from Alexandroupolis to Athens with daily breaks (850 km). Moreover, on 10th of April of 1993, he won the Greek national championships in 50 miles (80 km) running with the time of 6 hours 3 minutes and 36 seconds. Currently, Eleftherios is doing research in number theory (prime numbers), in linear algebra, and also the Euclidean and analytic geometry. Moreover, he conducts intensive research in the mathematical structure of the Hellenic language preparing his eleventh book.
