2. Leonhard Euler Leonhard Euler. Idérik matematiker med enestående hukommelse. Tross dette omtaleshan som en glad og livlig person. Leonhard Euler ble født i 1707. 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.

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. 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. Leonhard was sent to school in Basel and during this time he lived with his grandmother on his mother's side. This school was a rather poor one, by all accounts, and Euler learnt no mathematics at all from the school. However his interest in mathematics had certainly been sparked by his father's teaching, and he read mathematics texts on his own and took some private lessons. Euler's father wanted his son to follow him into the church and sent him to the University of Basel to prepare for the ministry. He entered the University in 1720, at the age of 14, first to obtain a general education before going on to more advanced studies.

Euler's father wanted his son to follow him into the church and sent him to the University of Basel to prepare for the ministry. However geometry soon became his favourite subject. Euler obtained his father's consent to change to mathematics after Johann Bernoulli had used his persuasion. Bernoulli became his teacher. He joined the St. Petersburg Academy of Science in 1727, two years after it was founded by Catherine I the wife of Peter the Great. Euler served as a medical lieutenant in the Russian navy from 1727 to 1730. In St Petersburg he lived with Daniel Bernoulli . He became professor of physics at the academy in 1730 and professor of mathematics in 1733. He married and left Bernoulli's house in 1733. He had 13 children altogether of which 5 survived their infancy. He claimed that he made some of his greatest discoveries while holding a baby on his arm with other children playing round his feet. The publication of many articles and his book Mechanica (1736-37), which extensively presented Newtonian dynamics in the form of mathematical analysis for the first time, started Euler on the way to major mathematical work.

Leonhard Euler By Katerina Kechris Euler was one the leading mathematicians of the 18th century. Although the majority of his work was in pure mathematics, he contributed to other disciplines, such as astronomy and physics, as well. In his lifetime he published more than 500 books and papers, and another 400 were published posthumously. Euler's contributions to mathematics cover a wide range, including analysis and the theory of numbers. He also investigated many topics in geometry. For example, he worked on the mathematics behind the Greek concept of 'Perfect Bodies'. The Greeks defined the perfect body as the form built from identical regular polyhedra. There are only five such polyhedra, the tetrahedron, cube, octahedron, dodecahedron and icosahedron. These concepts were forgotten until the Renaissance, when Pacioli and Leonardo da Vinci studied them. Kepler even tried to relate the perfect bodies to the orbits of the planets. Euler was able to relate the number of faces (F), vertices (V) and edges (E) of a polyhedron by the following equation, F + V = E + 2 from which one can derive that there are only five regular polyhdera.

Euler's complete works fill about 90 volumes. Remarkably, much of this output dates from the the last two decades of his life, when he was totally blind. Though born and educated in Basel, Switzerland, Euler spent most of his career in St. Petersburg and Berlin. He joined the St. Petersburg Academy of Sciences in 1727. In 1741 he went to Berlin at the invitation of Frederick the Great, but he and Frederick never got on well and in 1766 he returned to St. Petersburg, where he remained until his death. Euler's prolific output caused a tremendous problem of backlog: the St. Petersburg Academy continued publishing his work posthumously for more than 30 years. Euler married twice and had 13 children, though all but five of them died young. Euler's powers of memory and concentration were legendary. He could recite the entire

Leonhard Euler (1707-1783) De Zwitser Leonhard Euler was een wiskundige van de eerste grootte. Overal treft men zijn vondsten aan, in alle gebieden van de meetkunde, de algebra, de mechanica, de natuurkunde. Nog is, twee eeuwen na zijn leven en werken in Petersburg, zijn oeuvre niet geheel uitgegeven, waarmede de Russische Academie van Wetenschappen reeds vroeg een begin gemaakt heeft. Door keizerin Catharina I uit Basel naar de Russische hoofdstad geroepen en spoedig aan het hoofd gesteld van een laboratorium als professor in de theoretische en experimentele natuurkunde, heeft hij zich bezig gehouden met de studie van het geluid en daaraan een muzikale theorie vastgeknoopt, die in 1739 verscheen onder de titel Tentamen novae theoriae musicae . Dat is: Proeve ener nieuwe muziektheorie. Als een rechtgeaard voorlichter in de achttiende eeuw kan hij niet anders dan verzekerd zijn, dat er voor alles wat er geschiedt een reden moet kunnen worden gevonden, ook voor het feit, dat men deze muziek mooi vindt en die lelijk. Er moet een antwoord zijn op de vraag, waarom het ene volk van een bepaalde muziek geniet, terwijl een ander volk daarvan afkerig is. Hij schrijft dit toe aan een zekere orde die het oor in de klanken ontdekken kan. De mate waarin en het gemak waarmede wij die orde herkennen bepaalt het welbehagen, dat wij in de samenklank en de opeenvolging van klanken scheppen.

Leonhard Euler's Early Life As an Abstract Thinker (1707 - 1743) Alicia Graziosi Term Paper, History of Mathematics, Rutgers Modern mathematics incorporates the insights and ideas of many brilliant mathematical scholars of different epochs. Some of these mathematicians expanded the subject by introducing radically new theories and unexplored horizons. Leonhard Euler is of one the famous and accomplished members of this elite group of mathematicians. Euler earned his reputation in history as an ingenious mathematician by exploring new dimensions in mathematics. One of his best known discoveries is his identity, e^( i x)= cos(x)+ i sin(x). This celebrated equation is the result of combining trigonometry with the exponential function, which is one example that illustrates Euler's style of thinking and level of comfort with abstract ideas. Euler was a very gifted mathematician, not only in terms of what he accomplished, but also with regard to his methods. I believe Euler was an abstract thinker, and by this I mean two things; first, that he could clearly visualize challenging mathematical concepts in his mind with few if any concrete figures or drawings to guide him, and second, that he was able to apply transcendental ideas to known mathematical subjects. His talent was seen early in his life when he was only eighteen, in his paper on the masting of ships, and more fully later in his career in 1743 when he developed the formula cited above. On April 15, 1707 Basel, Switzerland gave birth to one of its greatest intellects, Leonhard Euler. (Bell, p. 143) Euler's father, Paul Euler, was a successful mathematician *who studied under Jakob Bernoulli (1654-1705). (Bell, p. 143) Paul Euler was Euler's first mathematics teacher, and he was also a Calvinist minister. Calvinism was an outgrowth of the Reformation initiated by Martin Luther in 1517 and became influential in Switzerland around 1546 when Protestants started ". insisting that the people - not just kings and bishops - should share in political and religious policymaking." (World Book Encyclopedia, p. 71)

Intro Leonhard Euler Pierre de Fermat Carl Friedrich Gauss Sophia Kowalewskaja Leonardo da Vinci ... Mathematicians Leonhard Euler The Swiss mathematician Leonhard Euler lived during the 18th century. Like many other great mathematicians he researched and made important contributions to every mathematical field. Euler wrote more scientific papers than any mathematician before or after him. In 1911 scholars began to publish his collected works. Wiliam Dunham wrote about this collection in 1994: "To date there are well over 70 volumes on the shelves (but who's counting?) and new ones will appear sporadically well into the twenty-first century. As a typical volume runs to 500 large pages and weighs about 4 pounds, the overall bulk of his Opera Omnia stands at more than 300 pounds! No other mathematician can match this poundage." Euler even found a new theorem in Euclidean geometry, a field which had been looked at as completed. Here's a short explanation of this theorem: The three heights of a triangle meet in point H, and the three perpendicular bisectors in point M. Point E in the middle of the line between H and M is the center of a circle on which are all the intersections of the heights and the perpendicular bisectors with the triangle.
