It was later edited and republished in Nobel Lectures. ![]() From Nobel Lectures, Physiology or Medicine 1963-1970, Elsevier Publishing Company, Amsterdam, 1972 This autobiography/biography was written at the time of the award and first published in the book series Les Prix Nobel. Laplace told his students, "Liesez Euler, Liesez Euler, c'est notre maître à tous" ("Read Euler, readĮuler, he is our master in everything" (Beckmann 1971, p. 153).Īdditional biographies: MacTutor (St. Since 1958 Ulf von Euler is married to countess Dagmar Cronstedt. Testament to Euler's proficiency in all branches of mathematics, the great French mathematician and celestial mechanic Finally, he proved theīinomial theorem was valid for any rational exponent. Had Euler pursued the matter, he would have discovered the constant of motion later found in aĭifferent form by Jacobi and known as the Jacobi integral.Įuler also found the solution to the two fixed center of force problem for a third body. In 1772, he introducedĪ synodic coordinates (rotating) coordinate system to the study of the three-body problem (especially the Harmonic series implied an infinite number of Primes, factoring the fifthįermat number (thus disproving Fermat's conjecture), proving Fermat's lesser theorem, and He also did important work in number theory, proving that that the divergence of the He computed the Riemann zeta function to for even numbers. ![]() To a complex power can be written as a complex number, and investigated the beta and gamma functions. Infinitorum (1748) provided the foundations of analysis. He made significant contributions to the study of differential equations. He also made major contributions in optics, mechanics, electricity, and Such huge quantities, Euler is reported to have replied that his pencil seemed to surpass him in intelligence.įrançois Arago said of him "He calculated just as men breathe, as eagles sustain themselves in theĪir" (Beckmann 1971, p. 143 Boyer 1968, p. 482).Įuler systematized mathematics by introducing the symbols e, i, andį( x) for f a function of x. When asked for an explanation why his memoirs flowed so easily in Prolific mathematical writer of all times finding time (even with his 13 children) to publish over 800 papers in his Large slate when his sight was failing him), he continued to publish his results by dictating them. Nevertheless, aided by his phenomenal memory (and having practiced writing on a He had a phenomenal memory, and once did a calculation in his head to settle anĪrgument between students whose computations differed in the fiftieth decimal place. He worked at the PetersburgĪcademy and Berlin Academy of Science. Leonhard Euler ( / lr / OY-lr, German: lenhat l ( listen) 15 April 1707 18 September 1783) was a Swiss mathematician, physicist, astronomer, geographer, logician and engineer who founded the studies of graph theory and topology and made pioneering and influential discoveries in many other branches of mathematics such as analyti. He also introduced much of the modern mathematical. Euler made important discoveries in fields as diverse as calculus, number theory, and topology. Swiss mathematician who was tutored by Johann Bernoulli. Leonhard Euler (pronounced Oiler IPA l) ( Basel, Switzerland, Ap St Petersburg, Russia, September 18, 1783) was a Swiss mathematician and physicist. ![]() Euler, Leonhard (1707-1783) - from Eric Weisstein's World of Scientific Biography
