24. Leonhard Euler Leonhard Euler. Idérik matematiker med enestående hukommelse. Leonhard EulerDet fortelles at to av Leonhard Eulers elever bad den helt blinde http://www.geocities.com/CapeCanaveral/Hangar/3736/euler.htm

Leonhard Euler Idérik matematiker med enestående hukommelse Det fortelles at to av Leonhard Eulers elever bad den helt blinde matematikeren om hjelp. De hadde hver for seg lagt sammen sytten ledd, og når de var ferdige skilte resultatene deres seg fra hverandre med ett siffer i den femte desimalen. Euler regnet da ut det hele i hodet - og hans summering var korrekt. Han hadde en enestående hukommelse for siffer og kunne altså dessuten utføre kompliserte regneoperasjoner i hodet. Han var som Isaac Newton og mange andre av den tidens vitenskapsmenn, en flersidig forsker. Forutenom matematikk og fysikk hadde han studert anatomi, kjemi og botanikk. Tidlig mistet han synet på det ene øyet, og de siste fjorten årene var han helt blind. Tross dette omtales han som en glad og livlig person. Leonhard Euler ble født i 1707. Han var sønn til Paul og Marguerite Euler, og familien bodde i nærheten av Basel i Sveits. Faren, som var prest, ville at sønnen skulle studere teologi, men ga slipp på tanken når han la merke til sønnens store interesse for matematikk. Leonhard begynte å studere tidlig. Når han var 17 år forsvarte han en avhandling ved universitetet i Basel og to år senere leverte han to avhandlinger til vitenskapsakademiet i Paris. Den ene bahandlet et problem med fartøy med master (og det av en mann som i sitt hjemland aldri skulle se et skip!), og den andre handlet om lydens filosofi. Dette ble opptakten til en lysende karriere. I 1727 ble han ansatt som forsker i matematikk ved vitenskapsakademiet i St. Petersburg. Seks år senere ble han utnevnt til professor ved akademiet, og samtidig giftet han seg med Catharina Gsell som var datteren til en sveitsisk kunstner. De fikk med tiden tretten barn. I begynnelsen av 1740-tallet ble Euler invitert av kongen av Preussen, Fredrik den store, til Berlin. I 1766 vendte han tilbake til Petersburg for å tilbringe resten av sitt liv der. Når han var 69 år døde hans hustru, men han giftet seg året etter med en halvsøster av Catharina Gsell.

Leonhard Euler (1707 - 1783) From `A Short Account of the History of Mathematics' (4th edition, 1908) by W. W. Rouse Ball. Leonhard Euler I think we may sum up Euler's work by saying that he created a good deal of analysis, and revised almost all the branches of pure mathematics which were then known, filling up the details, adding proofs, and arranging the whole in a consistent form. Such work is very important, and it is fortunate for science when it fall into hands as competent as those of Euler. Euler wrote an immense number of memoirs on all kinds of mathematical subjects. His chief works, in which many of the results of earlier memoirs are embodied, are as follows. In the first place, he wrote in 1748 his Introductio in Analysin Infinitorum , which was intended to serve as an introduction to pure analytical mathematics. This is divided into two parts. The first part of the Analysis Infinitorum contains the bulk of the matter which is to be found in modern text-books on algebra, theory of equations, and trigonometry. In the algebra he paid particular attention to the expansion of various functions in series, and to the summation of given series; and pointed out explicitly that an infinite series cannot be safely employed unless it is convergent. In the trigonometry, much of which is founded on F. C. Mayer's Arithmetic of Sines , which had been published in 1727, Euler developed the idea of John Bernoulli, that the subject was a branch of analysis and not a mere appendage of astronomy or geometry. he also introduced the trigonometrical functions, and shewed that the trigonometrical and exponential functions were connected by the relation

10.9. Euler, Leonard (1707-1783) IRA Leonhard Euler was one of top mathematicians of the eighteenth century and the greatest mathematician to come out of Switzerland. He made numerous contributions to almost every mathematics field and was the most prolific mathematics writer of all time. It was said that "Euler calculated without apparent effort, as men breathe...." He was dubbed "Analysis Incarnate" by his peers for his incredible ability. Leonhard Euler was born in Basel, Switzerland, on April 15, 1707. His father, a Calvinist pastor and former mathematician, planned the life of a clergyman for his son and originally Leonhard followed that path. He graduated from the University of Basel in 1724 where he studied theology and Hebrew. During his time at the school, however, he was privately tutored in mathematics by Johann Bernoulli. Johann was so impressed by his pupil's ability that he convinced Euler's father to allow Leonhard to become a mathematician. Euler took up a position at the Academy of Sciences in St. Petersburg, Russia, in 1727 and became the professor of mathematics six years later. During his stay, he was married and would over his lifetime have thirteen children, five of which would survive to adulthood. While in Russia, he lost sight in one eye after working day and night for three days to solve a problem. The question, which was a public contest, took all the other mathematicians involved months to figure out. He also discovered that the Czar's government was far from democratic as he was followed by secret police. He looked for a way out.

Branch of Science Mathematicians Nationality Swiss Euler, Leonhard (1707-1783) Swiss mathematician who was tutored by Johann Bernoulli . He worked at the Petersburg Academy and Berlin Academy of Science. He had a phenomenal memory, and once did a calculation in his head to settle an argument between students whose computations differed in the fiftieth decimal place. Euler lost sight in his right eye in 1735, and in his left eye in 1766. Nevertheless, aided by his phenomenal memory (and having practiced writing on a large slate when his sight was failing him), he continued to publish his results by dictating them. Euler was the most prolific mathematical writer of all times finding time (even with his 13 children) to publish over 800 papers in his lifetime. He won the Paris Academy Prize 12 times. When asked for an explanation why his memoirs flowed so easily in such huge quantities, Euler is reported to have replied that his pencil seemed to surpass him in intelligence. said of him "He calculated just as men breathe, as eagles sustain themselves in the air" (Beckmann 1971, p. 143; Boyer 1968, p. 482). Euler systematized mathematics by introducing the symbols e i , and f x ) for f a function of x . He also made major contributions in optics, mechanics, electricity, and magnetism. He made significant contributions to the study of differential equations. His

In the field of philosophy, Euler was the first to systematically employ logic diagrams to map out the structure of logical statements and arguments. Circles to represent classes and diagram syllogisms had earlier been used by Leibniz and others, but Euler was the first to explain in detail how the circles can and should be used.

Leonhard Euler (1707-1783) One of the greatest figures in the 18th century. Laplace said, "Read Euler, read Euler. He is the master of us all." Euler was born in Basel, Switzerland, and studied under Johann Bernoulli. When Euler was 20 years old, he obtained a post in St. Petersburg Academy, Russia. Petersburg was stimulating , because there were a number of eminent scholars (Daniel Bernoulli, among others), and Euler was quite productive. Euler was the first to give an analytical treatment (in terms of differential equations, not in terms of older geometrical method like Newton's) of mechanical problems, and he published Mechanica (1736-37). However, he lost the sight of the right eye, because of illness and strain. Then in 1741, he was invited to Berlin, where Frederick the Great established Berlin Academy (1744). During the 25 years in Berlin, he was again prolific and produced well more than 300 papers. During this period, he published a short paper in French, "Reflexions sur l'espace et le temps"
