Leonhard EulerLeonhard Euler (pronounced Oiler; IPA [ˈɔʏlɐ]) (April 15, 1707 – September 18 [O.S. September 7] 1783) was a pioneering Swiss mathematician and physicist, who spent most of his life in Russia and Germany. He published more papers than any other mathematician in history.[1]Euler made important discoveries in fields as diverse as calculus and topology. He also introduced much of the modern mathematical terminology and notation, particularly for mathematical analysis, such as the notion of a mathematical function.[2] He is also renowned for his work in mechanics, optics, and is considered to be the preeminent mathematician of the 18th century and one of the greatest of all time. He is also one of the most prolific; his collected works fill 60–80 quarto volumes.[3] A statement attributed to Pierre-Simon Laplace expresses Eulers influence on mathematics: Read Euler, read Euler, he is a master for us all.[4]Euler was featured on the sixth series of the Swiss 10-franc banknote[5] and on numerous Swiss, German, and Russian postage stamps. The asteroid 2002 Euler was named in his honor. He is also commemorated by the Lutheran Church on their Calendar of Saints on May [hide]1 Biography1.1 Childhood1.2 St. Petersburg1.3 Berlin1.4 Eyesight deterioration1.5 Last stage of life2 Contributions to mathematics2.1 Mathematical notation2.2 Analysis2.3 Number theory2.4 Graph theory2.5 Applied mathematics2.6 Physics and astronomy2.7 Logic3 Philosophy and religious beliefs4 Selected bibliography5 See also6 Notes7 Further reading8 External links[edit] Biography[edit] ChildhoodSwiss 10 Franc banknote honoring Euler, the most successful Swiss mathematician in was born in Basel to Paul Euler, a pastor of the Reformed Church, and Marguerite Brucker, a pastors daughter. He had two younger sisters named Anna Maria and Maria Magdalena. Soon after the birth of Leonhard, the Eulers moved from Basel to the town of Riehen, where Euler spent most of his childhood. Paul Euler was a family friend of the Bernoullis, and Johann Bernoulli, who was then regarded as Europes foremost mathematician, would eventually be an important influence on the young Leonhard. His early formal education started in Basel, where he was sent to live with his maternal grandmother. At the age of thirteen he matriculated at the University of Basel, and in 1723, received a masters of philosophy degree with a dissertation that compared the philosophies of Descartes and Newton. At this time, he was receiving Saturday afternoon lessons from Johann Bernoulli, who quickly discovered his new pupils incredible talent for mathematics.[6]Euler was at this point studying theology, Greek, and Hebrew at his fathers urging, in order to become a pastor. Johann Bernoulli intervened, and convinced Paul Euler that Leonhard was destined to become a great mathematician. In 1726, Euler completed his Ph.D. dissertation on the propagation of sound with the title De Sono[7] and in 1727, he entered the Paris Academy Prize Problem competition, where the problem that year was to find the best way to place the masts on a ship. He won second place, losing only to Pierre Bouguer—a man now known as the father of naval architecture. Euler, however, would eventually win the coveted annual prize twelve times in his career.[8][edit] St. PetersburgAround this time Johann Bernoullis two sons, Daniel and Nicolas, were working at the Imperial Russian Academy of Sciences in St Petersburg. In July 1726, Nicolas died of appendicitis after spending a year in Russia, and when Daniel assumed his brothers position in the mathematics/physics division, he recommended that the post in physiology that he had vacated be filled by his friend Euler. In November 1726 Euler eagerly accepted the offer, but delayed making the trip to St Petersburg. In the interim he unsuccessfully applied for a physics professorship at the University of Basel.[9]1957 stamp of the former Soviet Union commemorating the 250th birthday of Euler. The text says: 250 years from the birth of the great mathematician and academician, Leonhard arrived in the Russian capital on May 17, 1727. He was promoted from his junior post in the medical department of the academy to a position in the mathematics department. He lodged with Daniel Bernoulli with whom he often worked in close collaboration. Euler mastered Russian and settled into life in St Petersburg. He also took on an additional job as a medic in the Russian Navy.[10]The Academy at St. Petersburg, established by Peter the Great, was intended to improve education in Russia and to close the scientific gap with Western Europe. As a result, it was made especially attractive to foreign scholars like Euler: the academy possessed ample financial resources and a comprehensive library drawn from the private libraries of Peter himself and of the nobility. Very few students were enrolled in the academy so as to lessen the facultys teaching burden, and the academy emphasized research and offered to its faculty both the time and the freedom to pursue scientific questions.[8]However, the Academys benefactress, Catherine I, who had attempted to continue the progressive policies of her late husband, died the day of Eulers arrival. The Russian nobility then gained power upon the ascension of the twelve-year-old Peter II. The nobility were suspicious of the academys foreign scientists, and thus cut funding and caused numerous other difficulties for Euler and his improved slightly upon the death of Peter II, and Euler swiftly rose through the ranks in the academy and was made professor of physics in 1731. Two years later, Daniel Bernoulli, who was fed up with the censorship and hostility he faced at St. Petersburg, left for Basel. Euler succeeded him as the head of the mathematics department.[11]On January 7, 1734, he married Katharina Gsell, daughter of a painter from the Academy Gymnasium. The young couple bought a house by the Neva River, and had thirteen children, of whom only five survived childhood.[12][edit] BerlinStamp of the former German Democratic Republic honoring Euler on the 200th anniversary of his death. In the middle, it is showing his polyhedral about continuing turmoil in Russia, Euler debated whether to stay in St. Petersburg or not. Frederick the Great of Prussia offered him a post at the Berlin Academy, which he accepted. He left St. Petersburg on June 19, 1741 and lived twenty-five years in Berlin, where he wrote over 380 articles. In Berlin, he published the two works which he would be most renowned for: the Introductio in analysin infinitorum, a text on functions published in 1748 and the Institutiones calculi differentialis, a work on differential calculus.[13]In addition, Euler was asked to tutor the Princess of Anhalt-Dessau, Fredericks niece. He wrote over 200 letters to her, which were later compiled into a best-selling volume, titled the Letters of Euler on different Subjects in Natural Philosophy Addressed to a German Princess. This work contained Eulers exposition on various subjects pertaining to physics and mathematics, as well as offering valuable insight on Eulers personality and religious beliefs. This book ended up being more widely read than any of his mathematical works, and was published all across Europe and in the United States. The popularity of the Letters testifies to Eulers ability to communicate scientific matters effectively to a lay audience, a rare ability for a dedicated research scientist.[13]Despite Eulers immense contribution to the Academys prestige, he was eventually forced to leave Berlin. This was caused in part by a personality conflict with Frederick. Frederick came to regard him as unsophisticated especially in comparison to the circle of philosophers the German king brought to the Academy. Voltaire was among those in Fredericks employ, and the Frenchman enjoyed a favored position in the kings SOCial circle. Euler, a simple religious man and a hard worker, was very conventional in his beliefs and tastes. He was in many ways the direct opposite of Voltaire. Euler had very limited training in rhetoric and tended to debate matters that he knew little about, making him a frequent target of Voltaires wit.[13] Frederick also expressed disappointment with Eulers practical engineering abilities:I wanted to have a water jet in my garden: Euler calculated the force of the wheels necessary to raise the water to a reservoir, from where it should fall back through channels, finally spurting out in SANssouci. My mill was carried out geometrically and could not raise a mouthful of water closer than fifty paces to the reservoir. Vanity of vanities! Vanity of geometry![14][edit] Eyesight deteriorationA 1753 portrait by Emanuel Handmann. This portrayal suggests problems of the right eyelid and that Euler is perhaps suffering from strabismus. The left eye appears healthy, as it was a later cataract that destroyed it.[15]Eulers eyesight worsened throughout his mathematical career. Three years after suffering a near-fatal fever in 1735 he became nearly blind in his right eye, but Euler rather blamed his condition on the painstaking work on cartography he performed for the St. Petersburg Academy. Eulers sight in that eye worsened throughout his stay in Germany, so much so that Frederick referred to him as Cyclops. Euler later suffered a cataract in his good left eye, rendering him almost totally blind a few weeks after its discovery. Even so, his condition appeared to have little effect on his productivity, as he compensated for it with his mental calculation skills and photographic memory. For example, Euler could repeat the Aeneid of Virgil from beginning to end without hesitation, and for every page in the edition he could indicate which line was the first and which the last.[3][edit] Last stage of lifeEulers grave at the Alexander Nevsky situation in Russia had improved greatly since the ascension of Catherine the Great, and in 1766 Euler accepted an invitation to return to the St. Petersburg Academy and spent the rest of his life in Russia. His second stay in the country was marred by tragedy. A 1771 fire in St. Petersburg cost him his home and almost his life. In 1773, he lost his wife of 40 years. Euler would remarry three years September 18, 1783, Euler passed away in St. Petersburg after suffering a brain hemorrhage and was buried in the Alexander Nevsky Laura. His eulogy was written for the French Academy by the French mathematician and philosopher Marquis de Condorcet, and an account of his life, with a list of his works, by Nikolaus von Fuss, Eulers son-in-law and the secretary of the Imperial Academy of St. Petersburg. Condorcet commented, cessa de calculer et de vivre, (he ceased to calculate and to live).[16][edit] Contributions to mathematicsEuler worked in almost all areas of mathematics: geometry, calculus, trigonometry, algebra, and number theory, not to mention continuum physics, lunar theory and other areas of physics. His importance in the history of mathematics cannot be overstated: if printed, his works, many of which are of fundamental interest, would occupy between 60 and 80 quarto volumes[3] and Eulers name is associated with an impressive number of topics. The 20th century Hungarian mathematician Paul Erdős is perhaps the only other mathematician who could be considered to be as prolific.[edit] Mathematical notationEuler introduced and popularized several notational conventions through his numerous and widely circulated textbooks. Most notably, he introduced the concept of a function[2] and was the first to write f(x) to denote the function f applied to the argument x. He also introduced the modern notation for the trigonometric functions, the letter e for the base of the natural logarithm (now also known as Eulers number), the Greek letter ∑ for summations and the letter i to denote the imaginary unit.[17] The use of the Greek letter π to denote the ratio of a circles circumference to its diameter was also popularized by Euler, although it did not originate with him.[18] Euler also contributed to the development of the the history of complex numbers system (the notation system of defining negative roots with a + bi).[19][edit] AnalysisThe development of calculus was at the forefront of 18th century mathematical research, and the Bernoullis—family friends of Euler—were responsible for much of the early progress in the field. Thanks to their influence, studying calculus naturally became the major focus of Eulers work. While some of Eulers proofs may not have been acceptable under modern standards of rigour,[20] his ideas led to many great is well known in analysis for his frequent use and development of power series: that is, the expression of functions as sums of infinitely many terms, such asNotably, Euler discovered the power series expansions for e and the inverse tangent function. His daring (and, by modern standards, technically incorrect) use of power series enabled him to solve the famous Basel problem in 1735:[20]A geometric interpretation of Eulers formulaEuler introduced the use of the exponential function and logarithms in analytic proofs. He discovered ways to express various logarithmic functions in terms of power series, and successfully defined logarithms for negative and complex numbers, thus greatly expanding the scope where logarithms could be applied in mathematics.[17] He also defined the exponential function for complex numbers and discovered its relation to the trigonometric functions. For any real number φ, Eulers formula states that the complex exponential function satisfiesA special case of the above formula is known as Eulers identity,called the most remarkable formula in mathematics by Richard Feynman, for its single uses of the notions of addition, multiplication, exponentiation, and equality, and the single uses of the important constants 0, 1, e, i, and π.[21]In addition, Euler elaborated the theory of higher transcendental functions by introducing the gamma function and introduced a new method for solving quartic equations. He also found a way to calculate integrals with complex limits, foreshadowing the development of modern complex analysis, and invented the calculus of variations including its most well-known result, the Euler-Lagrange also pioneered the use of analytic methods to solve number theory problems. In doing so, he united two disparate branches of mathematics and introduced a new field of study, analytic number theory. In breaking ground for this new field, Euler created the theory of hypergeometric series, q-series, hyperbolic trigonometric functions and the analytic theory of continued fractions. For example, he proved the infinitude of primes using the divergence of the harmonic series, and used analytic methods to gain some understanding of the way prime numbers are distributed. Eulers work in this area led to the development of the prime number theorem.[22][edit] Number theoryEulers great interest in number theory can be traced to the influence of his friend in the St. Petersburg Academy, Christian Goldbach. A lot of his early work on number theory was based on the works of Pierre de Fermat. Euler developed some of Fermats ideas while disproving some of his more outlandish focus of Eulers work was to link the nature of prime distribution with ideas in analysis. He proved that the sum of the reciprocals of the primes diverges. In doing so, he discovered the connection between Riemann zeta function and prime numbers, known as the Euler product formula for the Riemann zeta proved Newtons identities, Fermats little theorem, Fermats theorem on sums of two squares, and made distinct contributions to Lagranges four-square theorem. He also invented the totient function φ(n) which assigns to a positive integer n the number of positive integers less than n and coprime to n. Using properties of this function he was able to generalize Fermats little theorem to what would become known as Eulers theorem. He further contributed significantly to the understanding of perfect numbers, which had fascinated mathematicians since Euclid. Euler made progress toward the prime number theorem and conjectured the law of quadratic reciprocity. The two concepts are regarded as the fundamental theorems of number theory, and his ideas paved the way for Carl Friedrich Gauss.[23][edit] Graph theorySee also: Seven Bridges of KönigsbergMap of Königsberg in Eulers time showing the actual layout of the seven bridges, highlighting the river Pregel and the 1736, Euler solved a problem known as the Seven Bridges of Königsberg.[24] The city of Königsberg, Prussia (now Kaliningrad, Russia) is set on the Pregel River, and included two large islands which were connected to each other and the mainland by seven bridges. The question is whether it is possible to walk with a route that crosses each bridge exactly once, and return to the starting point. It is not; and therefore not an Eulerian circuit. This solution is considered to be the first theorem of graph theory and planar graph theory.[24] Euler also introduced the notion now known as the Euler characteristic of a space and a formula relating the number of edges, vertices, and faces of a convex polyhedron with this constant. The study and generalization of this formula, specifically by Cauchy[25] and LHuillier,[26] is at the origin of topology.[edit] Applied mathematicsSome of Eulers greatest successes were in using analytic methods to solve real world problems, describing numerous applications of Bernoullis numbers, Fourier series, Venn diagrams, Euler numbers, e and π constants, continued fractions and integrals. He integrated Leibnizs differential calculus with Newtons method of fluxions, and developed tools that made it easier to apply calculus to physical problems. He made great strides in improving the numerical approximation of integrals, inventing what are now known as the Euler approximations. The most notable of these approximations are Eulers method and the Euler-Maclaurin formula. He also facilitated the use of differential equations, in particular introducing the Euler-Mascheroni constant:One of Eulers more unusual interests was the application of mathematical ideas in music. In 1739 he wrote the Tentamen novae theoriae musicae, hoping to eventually integrate musical theory as part of mathematics. This part of his work, however, did not receive wide attention and was once described as too mathematical for musicians and too musical for mathematicians.[27][edit] Physics and astronomyEuler helped develop the Euler-Bernoulli beam equation, which became a cornerstone of engineering. Aside from successfully applying his analytic tools to problems in classical mechanics, Euler also applied these techniques to celestial problems. His work in astronomy was recognized by a number of Paris Academy Prizes over the course of his career. His accomplishments include determining with great accuracy the orbits of comets and other celestial bodies, understanding the nature of comets, and calculating the parallax of the sun. His calculations also contributed to the development of accurate longitude tables.[28]In addition, Euler made important contributions in optics. He disagreed with Newtons corpuscular theory of light in the Opticks, which was th
