	Leonhard Euler - Wikipedia, the free encyclopedia
		Leonhard Euler was born in Basel, Switzerland, the son of Paul Euler, a Lutheran minister.
		In 1727 Euler was called to St. Petersburg by Catherine I of Russia and became professor of physics in 1730, with an additional mathematics appointment in 1733.
		Euler wrote Tentamen novae theoriae musicae in 1739 which was an attempt to combine mathematics and music; a biography comments that the work was "for musicians too advanced in its mathematics and for mathematicians too musical".

		Having taken his degree as master of arts in I 723, Euler applied himself, at his fathers desire, to the study of theology and the Oriental languages with the view of entering the church, but, with his fathers consent, he soon returned to geometry as his principal pursuit.
		In 1755 Euler had been elected a foreign member of the Academy of Sciences at Paris, and some time afterwards the academical prize was adjudged to three of his memoirs Concerning the Inequalities -in the Motions of the Planets.
		Eulers knowledge was more general than might have been expected in one who had pursued with such unremitting ardour mathematics and astronomy as his favorite studies.

	Leonhard Euler Biography
		Euler was born in Switzerland, in the town of Basel, on the 15th of April 1707, in the family of a pastor.
		When Euler returned to Petersburg with his two elder sons they were given a two-storey house on the banks of the Neva and Euler given a position at the head of the Academy of Sciences.
		Euler took a very active role in the observation of the movement of Venus across the face of the sun, despite the fact that at this time he was nearly blind.

	Leonard Euler
		Euler wanted to return to a position in western Europe, but the frequent arrival of children held him where he was.
		Euler had always had an outstanding memory and could do enormous calculations in his head, so he prepared for the coming blindness by learning to write formulas on a slate and to dictate mathematics to a son or secretary.
		Euler made fundamental contributions to several areas of science including fluid dynamics, lunar orbit theory (tides), mechanics and "the mathematical theory of investment" (insurance, annuities, pensions), as well as to essentially all of the areas of mathematics which existed at that time.

	Euler
		Euler wrote an article on acoustics, which went on to become a classic, in his bid for selection to the post but he was not chosen to go forward to the stage where lots were drawn to make the final decision on who would fill the chair.
		Euler became professor of physics at the Academy in 1730 and, since this allowed him to become a full member of the Academy, he was able to give up his Russian navy post.
		Euler was also helped by two other members of the Academy, W L Krafft and A J Lexell, and the young mathematician N Fuss who was invited to the Academy from Switzerland in 1772.

	Leonhard Euler (1707 - 1783)
		I think we may sum up Euler's work by saying that he created a good deal of analysis, and revised almost all the branches of pure mathematics which were then known, filling up the details, adding proofs, and arranging the whole in a consistent form.
		Euler commenced this part by dividing curves into algebraical and transcendental, and established a variety of propositions which are true for all algebraical curves.
		This method is not convenient, but it was from Euler's results that Mayer constructed the lunar tables for which his widow in 1770 received 5000 pounds from the English parliament, and in recognition of Euler's services a sum of 300 pounds was also voted as an honorarium to him.

	LEONHARD EULER (Site not responding. Last check: 2007-10-21)
		Leonhard Euler (1707-1783) was arguably the greatest mathematician of the eighteenth century (His closest competitor for that title is Lagrange) and one of the most prolific of all time; his publication list of 886 papers and books may be exceeded only by Paul Erdös.
		But there is another "Euler's formula" that (to use the modern terminology adopted long after Euler's death) gives the values of the Riemann zeta function at positive even integers in terms of Bernoulli numbers.
		Euler's study of the bridges of Königsberg can be seen as the beginning of combinatorial topology (which is why the Euler characteristic bears his name).

		This page lists proofs of the Euler formula: for any convex polyhedron, the number of vertices and faces together is exactly two more than the number of edges.
		According to Malkevitch, this formula was discovered in around 1750 by Euler, and first proven by Legendre in 1794.
		Perhaps there is a proof of Euler's formula that uses these polynomials directly rather than merely translating one of the inductions into polynomial form.

	Euler Angles are Evil.
		When you store rotation as Euler angles, there can be tiny amounts of roundoff error - if you change heading by 0.1 degrees for 3600 frames, the resulting net heading won't quite be zero.
		However, care has to be taken since the step of converting a matrix back into Euler angles results in some 'unknown' values at some orientations.
		In addition to Euler Angler representations and the Matrix representation, there is a third useful way to represent rotation.
