Leonhard Euler (b. April 15, 1707, Basel, Switz.d. Sept. 18, 1783, St. Petersburg, Russia), Swiss mathematician and physicist, one of the founders of pure mathematics. He not only made decisive and formative contributions to the subjects of geometry, calculus, mechanics, and number theory but also developed methods for solving problems in observational astronomy and demonstrated useful applications of mathematics in technology and public affairs. Euler's mathematical ability earned him the esteem of Johann Bernoulli, one of the first mathematicians in Europe at that time, and of his sons Daniel and Nicolas. In 1727 he moved to St. Petersburg, where he became an associate of the St. Petersburg Academy of Sciences and in 1733 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. Overtaxing himself, Euler in 1735 lost the sight of one eye. Then, invited by Frederick the Great in 1741, he became a member of the Berlin Academy, where for 25 years he produced a steady stream of publications, many of which he contributed to the St. Petersburg Academy, which granted him a pension. In 1748, in his

There are Euler theorems, Euler numbers and Euler formulas in a different fields, each distinct because Euler contributed to so many specialties. 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. This understanding would later be expanded upon by John Venn and such diagrams are now known as Venn Diagrams.

Biografía de Euler Suiza: centro matemático A finales del siglo XVII y a principios del XVIII, Suiza fue el lugar de nacimiento de muchas de las figuras más importantes de la matemática de la época. Se puede mencionar la obra del clan de los Bernoulli, así como la de Hermann, uno de sus protegidos suizos, pero el matemático más destacado que produjo Suiza durante esta época (o en cualquier otra de la historia) fue Leonhard Euler (1707-1783), que nació en Basilea. El padre de Euler era un pastor calvinista que, lo mismo que el padre de Jacques Bernoulli, esperaba que su hijo siguiera también el camino del sagrado misterio. El muchacho, sin embargo estudió con Jean Bernoulli junto a sus hijos Nicolás y Daniel, y en este ambiente favorable descubrió su vocación. El viejo Euler también tenía una buena preparación matemática, habiendo sido discípulo de Jacques Bernoulli en su juventud, y colaboró en la instrucción de su hijo en los elementos básicos de la matemática, a pesar de mantener la esperanza de que Leonhard siguiese una carrera teológica. En cualquier caso, el joven Euler recibió una educación muy completa, ya que al estudio de la matemática se unió el de la teología, la medicina, la astronomía, la física y las lenguas orientales. Terminó brillantemente la Universidad, obtuvo el grado científico de maestro, pero no pudo encontrar trabajo, al no lograr una plaza de profesor vacante en Basilea. Primera estancia en San Petersburgo Sin embargo, la amplitud de conocimientos adquiridos le resultó muy útil cuando en 1727 recibió una invitación para trabajar en la Academia de Ciencias de San Petersburgo en Rusia, donde se encontraban desde dos años antes, trabajando como profesores de matemáticas, los hermanos Nicolás y Daniel Bernoulli. Esta importante institución había sido fundada en el año 1725 por Catalina I, siguiendo las líneas trazadas por su difunto esposo Pedro el Grande, aconsejado por Leibniz. Fue la primera institución científica de Rusia. Para llevar a cabo el trabajo y la preparación de los especialistas del país fueron invitados de otros países jóvenes y talentosos profesores, como los ya mencionados hermanos Bernoulli, J. Hermann que había sido antes profesor en Padua y después en Frankfurt del Oder. Finalmente llegó Euler.

Distributed for the Thoemmes Press. 1137 p., 2 Volumes. 1997 Cloth CUSA $240.00tx 1-85506-507-X Leonhard Euler (1707-83) was one of the greatest mathematicians of his own or any other age. Born at Basel in Switzerland and intended for the Calvinist ministry, his prodigious analytical gifts soon became apparent and led him to become one of the luminaries of the academies of Berlin and Saint Petersburg. During his stay in Berlin (1741-66), he was asked to provide some tuition in Natural Philosophy for Princess d'Anhalt Dessau, a niece of Frederick the Great. These justly renowned letters are the fruit of that royal request. These Letters to a German Princess are one of the great documents of the Enlightenment, and testament to the faith of the age in education. This faith is also evidenced in the progressive attitude to women's learning, making this a key work in the history of female education. Read today, the Letters still stand as a clear and thorough guide through the fundamentals of natural science and philosophy, and still succeed in Euler's aim - to excite in the reader the passion for learning. includes original notes, glossary of foreign and scientific terms, and c. 20 diagrams over 230 letters an important work in the history of science and philosophy, and the history of female education

Biografías Euler, Leonhard atemático suizo (1707-83), nacido en Basilea, San Petesburgo, y considerado el mejor de su época. Inventó el sistema de funciones que llevan su nombre. Perfeccionó todas las ramas de la matemática pura el análisis, sobre todo, y realizó trabajos excelentes en las partes más diversas de la matemática aplicada. En aritmética y teoría de los números, su máxima contribución se refiere a la teoría de los números primos, iniciando la teoría analítica que se desarrolló un siglo más tarde. En álgebra se ocupó de la eliminación, descomposición en fracciones simples, teoría de ecuaciones, etc. Pretendiendo dar un método general para resolver ecuaciones de cualquier grado, ideó un procedimiento válido hasta las de cuarto grado inclusive. Pero el trabajo más original de Euler se desarrolla en el cálculo infinitesimal. A los veinte años consiguió el primero de los doce premios que, con el tiempo, había de concederle la Academia Francesa y, por invitación de Catalina I de Rusia, se incorporó a la Academia de San Petersburgo merced a la gestión de los Bernoulli, instalados allí desde 1725. En 1733 sucedió a Daniel Bernoulli al frente de la sección de matemáticas de dicha Academia, y al año siguiente contrajo matrimonio con la hija de un pintor suizo que Pedro el Grande había traído a Rusia. En 1741, invitado por Federico II el Grande, se trasladó a la Academia de Berlín, al frente de la cual sucedió a Maupertuis en 1756, como presidente en funciones. En 1766 aceptó una oferta de Catalina la Grande para reincorporarse a San Petersburgo. Ese mismo año quedó ciego a causa de una afección de cataratas, tras haber perdido ya la visión del ojo derecho en 1735.

Euler, Leonhard Swiss mathematician. He developed the theory of differential equations and the calculus of variations, and worked in astronomy and optics. He also enlarged mathematical notation. Euler developed spherical trigonometry and demonstrated the significance of the coefficients of trigonometric expansions; Euler's number (e, as it is now called) has various useful theoretical properties and is used in the summation of particular series. Euler was born and educated in Basel, a pupil of Johann Bernoulli. He became professor of physics at the University of St Petersburg 1730. In 1741 he was invited to Berlin by Frederick the Great, where he spent 25 years before returning to Russia. Euler carried out research into the motion and positions of the Moon, and the gravitational relationships between the Moon, the Sun, and the Earth. His resulting work on tidal fluctuations took him into the realm of fluid mechanics.

Born and educated at Basel, where he knew the Bernoullis, he went to St. Petersburg (1727) at the invitation of Catherine I, becoming professor of mathematics there on the departure of Daniel Bernoulli (1733). He was invited to Berlin (1741) by Frederick the Great and remained there until 1766, when he returned to St. Petersburg. Euler was the most prolific mathematician who ever lived; his collected works run to more than seventy volumes. He contributed to numerous areas of both pure and applied mathematics, including the calculus of variations, analysis, number theory, algebra, geometry, trigonometry, analytical mechanics, hydrodynamics, and the lunar theory (calculation of the motion of the moon). Euler was one of the first to develop the methods of the calculus on a wide scale. Though half-blind for much of his life and totally blind for the last seventeen years, he retained to the end a near-legendary skill at calculation.

In this paper Euler establishes his famous formula V - E + F = 2 relating the number V of vertices, E of edges and F of faces of any polyhedron. This rather simple formula was missed by both Archimedes and Descartes, although both wrote extensively on polyhedra. Before Euler it seems to have been impossible to think of geometrical properties without measurement being involved. The second part of the paper (pp 140-160) gives a remarkably clever proof based on dissecting solids into tetrahedral slices. Euler's work was far ahead of its time: further advances in topology had to wait another century, with the work of Listing, Möbius and Riemann. 'Euler was also the author of the first studies on topology... In a letter to Goldbach [written in 1750 but published here in 1758] he cited a number of properties of polyhedra, among them the following: the number of vertices, S, edges, A, and sides H, of a polyhedron are connected by an equality S - A + H = 2... The Euler characteristic S - A + H and its generalization for multi-dimensional complexes as given by H. Poincaré is one of the principal invariants of modern topology' (DSB, stating wrongly that the theorem had been known to Descartes; this has now been proved erroneous).
