Google doodles geometry on Leonhard Euler's birth anniversary - Daily News & Analysis

Swiss mathematician and physicist Leonhard Euler who  made important discoveries in the field of infinitesimal calculus and graph theory has been honoured by Google on his 306th birth anniversary.  Euler area of work included: geometry, infinitesimal calculus, trigonometry, algebra, and number theory, as well as continuum physics, lunar theory and other areas of physics. The animated doodle is a scribe with geometrical shapes and mathematical formulae. Euler lost sight in his right eye in 1735, and in his left eye in 1766. He still continued to publish his results aided by his phenomenal memory and having practiced writing on a large slate when his sight was failing him. He published over 800 papers in his lifetime.  Euler had a phenomenal memory. Even though he lost vision in both his eyes, his productivity increased. "He instructed his assistants to read aloud the newly arrived books and journals, and he in turn dictated his ideas to a tableful of scribes working furiously to keep up. It is said that Euler could create mathematics faster than most people can write it, and he daily put his assistants to the test," observes William Dunham, Truman Koehler Professor of Mathematics, Muhlenberg College  "Like Beethoven, who wrote music that he never heard, Euler created mathematics that he never saw. This triumph in the face of adversity makes Euler's the most inspirational story in the history of mathematics," adds Dunham. His famous quotes are: - Mathematicians have tried in vain to this day to discover some order in the sequence of prime numbers, and we have reason to believe that it is a mystery into which the human mind will never penetrate. - For since the fabric of the universe is most perfect and the work of a most wise Creator, nothing at all takes place in the universe in which some rule of maximum or minimum does not appear. In mathematical analysis, Euler's identity is an equation [eip + 1 = 0] which Benjamin Peirce, another mathematician and US professor at Harvard described in the following way: Gentlemen, that is surely true, it is absolutely paradoxical; we cannot understand it, and we don't know what it means. But we have proved it, and therefore we know it must be the truth. Respondents called it "the most profound mathematical statement ever written"; "uncanny and sublime"; "filled with cosmic beauty"; and "mind-blowing".  Another asked: "What could be more mystical than an imaginary number interacting with real numbers to produce nothing?"  The equation contains nine basic concepts of mathematics — once and only once — in a single expression. These are: e (the base of natural logarithms); the exponent operation; π; plus (or minus, depending on how you write it); multiplication; imaginary numbers; equals; one; and zero. Euler was born in Basel on 15 April 1707.  via Technology - Google News http://news.google.com/news/url?sa=t&fd=R&usg=AFQjCNGN_ypboODTw19aU80AMAqwBnogJw&url=http://www.dnaindia.com/scitech/1822580/report-google-doodles-geometry-on-leonhard-euler-s-birth-anniversary
