Leonhard Euler Facts

Leonhard Euler Facts
Leonhard Euler (April 15, 1707 - September 18, 1783) was a Swiss mathematician and physicist who made key contributions to the fields of infinitesimal calculus and graph theory.
Interesting Leonhard Euler Facts:
Despite his Swiss birth, Euler spent much of his adulthood in St. Petersburg, Russia, and in Berlin, Prussia.
Euler introduced much of the mathematical terminology and notation that are still in use today, especially in mathematical analysis. One of these systems was mathematical function.
He is also widely remembered for his contributions in mechanics, fluid dynamics, optics, astronomy, and music.
Euler is remembered as the most important mathematician of the 18th century, as well as one of the greatest mathematicians who ever lived.
Pierre-Simon Laplace expressed Euler's importance to mathematics: "Read Euler, read Euler, he is the master of us all."
He is also one of the most prolific scholars and thinkers in the field of math, as his writings fill sixty to eighty quarto volumes.
Euler's father was friends with Johann Bernoulli, who at that time was thought of as Europe's foremost mathematician.
Bernoulli would grow to become the most influential figure in Euler's life.
Euler's Master's thesis was on a comparison between the philosophies of Newton and Descartes, while he still tutored under Bernoulli in math.
A later thesis by Euler was on the propagation of sound.
At the age of twenty, he received second prize in the annual Paris Academy Prize Problem, a competition who went on to win twelve times.
After Bernoulli convinced Euler's father to let him abandon studying to become a pastor, he went on to make important contributions to nearly all areas of math, including geometry, infinitesimal calculus, trigonometry, algebra, and number theory.
In science, Euler wrote extensively on ideas in continuum physics, lunar theory and other areas.
Euler has two numbers named after him.
The first is the Euler's Number in calculus, represented simply as e, which has an approximate value of 2.71828.
The second is the Euler-Mascheroni Constant γ (gamma), which is often referred to simply as "Euler's constant;" it has an approximate value of 0.57721.
He may be most well known for his various notations systems, many of which are still used in textbooks today.
Of all of his notations, Euler's most important may be the idea of the function, as he was the first mathematician to designate the function by writing it f(x).
In trigonometry, Euler was the first researcher to introduce a written system for the trigonometric functions using the letter e (now named after him) as the base.
