Leonhard Euler (OYler), born in Switzerland and schooled in Germany and Russia, is said to have been the greatest genius of the 18th century. Despite being blind for the later part of his life, Euler continued to amaze and astound the world with his memory and concentration. There are more than 90 mathematical terms named after Euler and he penned more than 850 papers. Euler is known for his works in math, physics, mechanics, and astronomy. Within the field of mathematics, he advanced the areas of number theory, combinatorics, probability, differential calculus, differential equations, infinite series, integration, and geometry. Among his most famous works are the Euler Line, Euler Circle, Prime Number Theorem, and the Seven Bridges of Konigsburg. View this great video, a tribute to this astounding mathematician.
