Leonhard Euler, Brilliant And Leading Scientists Of All Time

In the 17th century Switzerland had a mathematician and physicist who very brilliant and leading scientists of all time. The man was Leonhard Euler. The results of his work affects the use of all areas of physics and engineering in many areas.
The results of Euler's mathematics and science does not really make sense. He wrote 32 books complete, many of which consist of two volumes,
hundreds of articles about mathematics and science. People say, collection of scientific writings of over 70 volumes! Euler's genius to enrich nearly every aspect of pure mathematics and mathematical ready to use, and contributions to mathematical physics is almost no limit to the use.
Special Euler experts demonstrated how the general laws of mechanics, which has been formulated in the previous century by Isaac Newton, may be used in certain types of physical situations that occur repeatedly. For example, using Newton's laws of motion in terms of fluid, Euler equations can develop hydrodinamika. Also, through a careful analysis of the possible movement of heavy goods, and with the use of Newton's principles. And Euler developed a number of opinions capable of fully determine the motion of heavy goods. In practice, of course, things do not always object to be built. Therefore, Euler also made important contributions on the theory of elasticity that describes how solid objects can change shape through the use of external energy.

Euler also uses her talent in terms of mathematical analysis of problems in astronomy, especially concerning about the "three-entity" associated with the problem of how the sun, earth and moon move under their own gravity, the same individual. This problem - a problem that was thought to 21st century - not yet fully resolved. Incidentally, Euler was the only leading scientist of the 18th century who (correctly, as proved later) supports the wave theory of light.

Euler thoughts that poured endlessly it often produces a starting point for mathematical discovery that could make someone famous. For example, Joseph Louis Lagrange, the French mathematical physicist, succeeded in formulating a series of formula ( "formula Lagrange ') which has important theoretical meaning and can be used to solve various mechanical problems. Basic formula discovered by Euler, because it is often called the Euler-Lagrange formula. Another French mathematician Jean Baptiste Fourier, is generally credited with the discovery of mathematical techniques, known by the nickname of Fourier analysis. Here, too, the first basic formula discovered by Leonhard Euler, and is known by the nickname Euler-Fourier formulas. They found the use of an extensive and varied in the field of physics, including acoustics and electromagnetic theory.

When it comes to mathematics, Euler's particularly interested in the field of calculus, differential formula, and the infinity of a number. His contributions in this field, though very important, too technical here presented. His contributions in the field of calculus of variations and the theory of the complexity of the basis of all subsequent developments in this field. Both topics had a wide range of work in the field of the use of scientific practices, in addition to the importance in the field of pure mathematics.

Euler formula,, showed a link between the function and the number of imaginary trigonometrik, and can be used to find the logarithm of a negative number. This formula is one of the most widely used in all areas of mathematics. Euler also wrote a textbook on analytic geometry and made important contributions in the field of differential geometry and ordinary geometry.

Although Euler had a great ability to mathematical discoveries that allowed doing scientific practices, he almost had a surplus equivalent in the field of pure mathematics. Unfortunately, the contribution that so many in the field of number theory, but not so much that can be presented here. Euler was also the beginners who worked in the field of topology, a branch of mathematics that has important meaning in the 20th century.

Finally, Euler made important contributions of the mathematical symbol systems of today. For example, he is responsible for general use Greek letters to describe the ratio between the circumference of a circle to its diameter. He also introduced many a suitable system of signs that are now commonly used in mathematics.

Euler was born in 1707 in Basel, Switzerland. He was admitted into the University of Basel in 1720 when he was only thirteen years to reach. At first he studied theology, but soon moved to mathematics subjects. He obtained his bachelor's degree from the University of Basel at the age of seventeen, and when he was only twenty years old he received the invitation of Catherine I of Russia to join the Academy of Sciences in St. Petersburg. At age twenty-three years he became professor of physics there, and when he was twenty-six years he replaced the head of mathematics korsi formerly occupied by a famous mathematician Daniel Bernoulli. Two years later lost his eye sight side, but he continued working with full capacity, producing the articles are brilliant.

Year 1741 Frederick the Great of Prussia Euler persuade Russia to leave and asked him to join the Academy of Sciences in Berlin. He lived in Berlin for twenty-five years and returned to Russia in 1766. Not long after that his eyes could not see anymore. Even in this kind of calamity strikes, it is not to stop the investigation. Euler has a spectacular ability in mental arithmetic, and until he died (in 1783 in St. Petersburg - then Leningrad now - at the age of seventy-six years), he continued to issue high-grade paper in mathematics. Euler married twice and had thirteen children, eight of them died young.

All the findings could Euler made people even if he never lived in this world. Although I think the appropriate criteria used in this problem is to ask the questions: what will happen in the modern world if he never do anything? In connection with Leonhard Euler answer seems obvious: modern science and technology will be far left behind, almost inconceivable, without the Euler formula, formula, formulas, and methods. Index glance glance mathematics and physics textbook will show these explanations Euler angle (strong motion); stability of Euler (infinite series); balance Euler (hydrodinamika); balance Euler motion dynamics (hard object); formula Euler (complex variables ); sum Euler (infinite series), Eurel polygonal curve (differential balance); opinions about diversity Euler function (the balance of the differential part); transformation of Euler (infinite series); law of Bernoulli-Euler (elastisitis theory); Euler formula - Fourier (series trigonometris); balance Euler-Lagrange (variation calculus, mechanics); and Euler-Maclaurin formula (the sum method) is all about some of the essentials only.

From this angle, the reader may wonder why Euler was not able to place higher in the list order this book. The main reason is that, although he was a brilliant and successful show how Newton's laws can be applied, Euler never found a scientific principles alone. That's why characters like Becquerel, X-rays, and Gregor Mendel, who each found a new phenomena and basic scientific principles, placed in the upper order than Euler. But, however, Euler contribution to world science, the field of engineering and mathematics, not absurdly large grass.Michael H. Hart,One hundred most influential figures in the history.
