In he moved to St. Petersburg, where he became an associate of the St. Petersburg Academy of Sciences and in succeeded Daniel Bernoulli to the chair of mathematics. By means of his numerous books and memoirs that he submitted to the academy, Euler carried integral calculus to a higher degree of perfection, developed the theory of trigonometric and logarithmic functions, reduced analytical operations to a greater simplicity, and threw new light on nearly all parts of pure mathematics.

Paul Euler became a Protestant minister and married Margaret Brucker, the daughter of another Protestant minister. Their son Leonhard Euler was born in Basel, but the family moved to Riehen when he was one year old and it was in Riehen, not far from Basel, that Leonard was brought up.

Paul Euler had, as we have mentioned, some mathematical training and he was able to teach his son elementary mathematics along with other subjects.

This school was a rather poor one, by all accounts, and Euler learnt no mathematics at all from the school. He entered the University inat the age of 14, first to obtain a general education before going on to more advanced studies.

I soon found an opportunity to be introduced to a famous professor Johann Bernoulli. True, he was very busy and so refused flatly to give me private lessons; but he gave me much more valuable advice to start reading more difficult mathematical books on my own and to study them as diligently as I could; if I came across some obstacle or difficulty, I was given permission to visit him freely every Sunday afternoon and he kindly explained to me everything I could not understand Euler completed his studies at the University of Basel in He had studied many mathematical works during his time in Basel, and Calinger [ 24 ] has reconstructed many of the works that Euler read with the advice of Johann Bernoulli.

By Euler had already a paper in print, a short article on isochronous curves in a resisting medium. In he published another article on reciprocal trajectories and submitted an entry for the Grand Prize of the Paris Academy on the best arrangement of masts on a ship.

However, Euler now had to find himself an academic appointment and when Nicolaus II Bernoulli died in St Petersburg in July creating a vacancy there, Euler was offered the post which would involve him in teaching applications of mathematics and mechanics to physiology.

He accepted the post in November but stated that he did not want to travel to Russia until the spring of the following year. He had two reasons to delay. He wanted time to study the topics relating to his new post but also he had a chance of a post at the University of Basel since the professor of physics there had died.

Euler wrote an article on acoustics, which went on to become a classic, in his bid for selection to the post but he was not chosen to go forward to the stage where lots were drawn to make the final decision on who would fill the chair.

Almost certainly his youth he was 19 at the time was against him. However Calinger [ 24 ] suggests: As soon as he knew he would not be appointed to the chair of physics, Euler left Basel on 5 April Through the requests of Daniel Bernoulli and Jakob HermannEuler was appointed to the mathematical-physical division of the Academy rather than to the physiology post he had originally been offered.

At St Petersburg Euler had many colleagues who would provide an exceptional environment for him [ 1 ]: Euler served as a medical lieutenant in the Russian navy from to In St Petersburg he lived with Daniel Bernoulli who, already unhappy in Russia, had requested that Euler bring him tea, coffee, brandy and other delicacies from Switzerland.

Euler became professor of physics at the Academy in and, since this allowed him to become a full member of the Academy, he was able to give up his Russian navy post. Daniel Bernoulli held the senior chair in mathematics at the Academy but when he left St Petersburg to return to Basel in it was Euler who was appointed to this senior chair of mathematics.

The financial improvement which came from this appointment allowed Euler to marry which he did on 7 Januarymarrying Katharina Gsell, the daughter of a painter from the St Petersburg Gymnasium.

This is an excellent introduction to some of the mathematics of Euler. Chapter 1 is on multiplicative functions, particularly the sum of divisors function. Chapter 2 is on Euler's constant (for harmonic sums)/5(24). Leonhard Euler: his Life, the Man, and his Work Walter Gautschi 1 Introduction It is a virtually impossible task to do justice, in a short span of time and for the history of science in the 18th century. Euler’s years at the Academy of St. Petersburg proved to be a period of. Letters of Euler to a German Princess, On Different Subjects in Physics and Philosophy, Volume 1 Jan 2, by Henry Hunter and Jean-Antoine-Nicolas Carit De Condorcet.

Katharina, like Euler, was from a Swiss family. They had 13 children altogether although only five survived their infancy. Euler claimed that he made some of his greatest mathematical discoveries while holding a baby in his arms with other children playing round his feet.

This is done in [ 24 ] as follows: The core of his research program was now set in place: He viewed these three fields as intimately interconnected. Studies of number theory were vital to the foundations of calculus, and special functions and differential equations were essential to rational mechanics, which supplied concrete problems.

The publication of many articles and his book Mechanicawhich extensively presented Newtonian dynamics in the form of mathematical analysis for the first time, started Euler on the way to major mathematical work.

However, he kept this news from his parents and members of the Bernoulli family back in Basel until he had recovered. In his autobiographical writings Euler says that his eyesight problems began in with overstrain due to his cartographic work and that by he had [ 24 ]: He also argues that a portrait of Euler from suggests that by that stage the sight of his left eye was still good while that of his right eye was poor but not completely blind.The backward Euler method is an implicit method, meaning that the formula for the backward Euler method has + on both sides, so when applying the backward Euler method we have to solve an equation.

This makes the implementation more costly. Early Life and Education. Leonhard Euler was born on April 15, , in Basel, monstermanfilm.com: Apr 15, Leonhard Euler's father was Paul Euler.

Paul Euler had studied theology at the University of Basel and had attended Jacob Bernoulli's lectures there. In fact Paul Euler and Johann Bernoulli had both lived in Jacob Bernoulli's house while undergraduates at Basel. of results for "euler biography" Euler (Dolciani Mathematical Expositions) Dec 31, by William Dunham.
