1707 – Euler – bio

Leonhard Paul Euler was born in Basel, Switzerland in 1707 and was a mathematician and physicist. He made contributions in many areas of mathematics including: number theory, geometry, algebra, trigonometry, calculus and more. While Leibnitz was the first to use the word, “function” in a mathematical sense, it was Euler who defined it as an expression involving variables and constants and gave it the notation of f(x). He also introduced the use of the letter “e” to represent the natural logarithm, the letter “i” to represent the imaginary square root of negative one, and the Greek letter sigma to represent summations. Euler’s work with prime numbers created the foundation for later work by Gauss and Riemann on the zeta function. He solved a problem in graph theory known as “The Seven Bridges of Konigsberg” which helped lay the foundation for the field of topology
