Euler, Leonhard (170783), Swiss mathematician, whose major work was done in the field of pure mathematics, a field that he helped to found. Euler was born in Basel and studied at the University of Basel under the Swiss mathematician Johann Bernoulli, obtaining his master's degree at the age of 16. In 1727, at the invitation of Catherine I, empress of Russia, Euler became a member of the faculty of the Academy of Sciences in Saint Petersburg. He was appointed professor of physics in 1730 and professor of mathematics in 1733. In 1741 he became professor of mathematics at the Berlin Academy of Sciences at the urging of the Prussian king Frederick the Great. Euler returned to St. Petersburg in 1766, remaining there until his death. Although hampered from his late 20s by partial loss of vision and in later life by almost total blindness, Euler produced a number of important mathematical works and hundreds of mathematical and scientific memoirs.
In his Introduction to the Analysis of Infinities (1748; trans. 1748), Euler gave the first full analytical treatment of algebra, the theory of equations, trigonometry, and analytical geometry. In this work he treated the series expansion of functions and formulated the rule that only convergent infinite series can properly be evaluated. He also discussed threedimensional surfaces and proved that the conic sections are represented by the general equation of the second degree in two dimensions. Other works dealt with calculus, including the calculus of variations, number theory, imaginary numbers, and determinate and indeterminate algebra. Euler, although principally a mathematician, made contributions to astronomy, mechanics, optics, and acoustics

Euler may be the most influential mathematician who ever lived (though some would make him second to Euclid); he ranks #77 on Michael Hart's famous list of the Most Influential Persons in History. His colleagues called him "Analysis Incarnate." Laplace, famous for denying credit to fellow mathematicians, once said "Read Euler: he is our master in everything." His notations and methods in...

He made important discoveries in fields as diverse as infinitesimal calculus and graph theory. He also introduced much of the modern mathematical terminology and notation, particularly for mathematical analysis, such as the notion of amathematical function.[3] He...

LeonhardEuler (15 April, 1707 18 September, 1783) was a Swiss mathematician and physicist. Born in Basel Switzerland, later moved to neighboring town, Riehen, Euler attended a rather poor school that taught no mathematics. His father having studied theology at the University of Basil managed to teach him some, which ignited an...
...LeonhardEulerLeonhardEuler, (born April 15, 1707, died Sept. 18, 1783), was the most
prolific mathematician in history. His 866 books and articles represent about
one third of the entire body of research on mathematics, theoretical physics,
and engineering mechanics published between 1726 and 1800. In pure mathematics,
he integrated Leibniz's differential calculus and Newton's method of fluxions
into mathematical analysis; refined...
...Euler and Hamiltonian Circuits
As I type this sentence millions of students all over the country are in their math class either a) struggling to open their eyelids or b) tapping their fingers due to boredom and impatience. They have all failed to understand how the topic would later come of use. Although mathematics may seem to be “unnecessary” it teaches our brains to strategize, and think differently through the use of trial and error and problem solving. Most individuals...
...LeonhardEulerLeonhardEuler was born on the fifteenth day of April in the year seventeen hundred and seven, in Basel, Switzerland. He was considered one of the best scientists, and mathematicians to ever walk on the planet earth. He created over nine hundred publications, and was a member of the prestigious Petersburg Academy of Sciences. His studies include topics on shipbuilding, acoustics, optics, astronomy, mechanics, and...

...LeonhardEuler, a Swiss mathematics and physics genius, was born on April 15, 1707 in Basel Switzerland, and died on September 18, 1783 in Saint Petersburg. Before he died he has done many great things. He introduced mathematical notations, shorthand trigonometric functions, and the idea of function and how it is written(f(x)). He also invented the symbol pi (π) for the ratio of a circle's circumference to its diameter, the ‘e’ for the base of the natural...
