Euler's profound knowledge, endless creative energy and unprecedented rich works are amazing! He published papers from the age of 19 to the age of 76, and has written countless books and papers for more than half a century. Up to now, Euler's name can be seen in almost every mathematical field, from Euler line of elementary geometry, euler theorem of polyhedron, Euler transformation formula of solid analytic geometry, Euler solution of quartic equation to Euler function in number theory, Euler equation of differential equation, Euler constant of series theory and Euler equation of variational method. Euler formula of complex variable function, etc. , is countless. His contribution to mathematical analysis is even more original. Introduction to infinitesimal analysis is his epoch-making masterpiece, and mathematicians call him "the embodiment of analysis" at that time.
Euler is the most prolific outstanding mathematician in the history of science. According to statistics, * * * has written 886 books and papers in his tireless life, of which 40% is analysis, algebra and number theory, 18% is geometry, 28% is physics and mechanics, 1 1% is astronomy, as well as ballistics and navigation.
The amazing productivity of Euler's works is not accidental. He can work in any harsh environment. He often holds his children on his knees to finish his papers, regardless of their noise. His indomitable perseverance and tireless academic spirit made him blind, and he didn't stop studying mathematics. During the 17 years after his blindness, he also dictated several books and about 400 papers. Gauss (1777- 1855), a great mathematician in the 9th century, once said, "Studying Euler's works is always the best way to understand mathematics."
Euler's father Paul Euler is also a mathematician. He wants little Euler to study theology and teach him a little math at the same time. Because of his talent and extremely diligent spirit, he got johann bernoulli's appreciation and special guidance. When he was 19 years old, he wrote a paper on the mast and won a prize from the Paris Academy of Sciences. His father no longer opposed him to study mathematics.
Johann bernoulli's son daniel bernoulli went to Russia on 1725 and recommended Euler to czar Cadling I. In this way, Euler came to Petersburg on 17 and 1733. At the age of 26, Euler became a professor of mathematics at the Academy of Sciences in Petersburg. 1735, Euler solved a problem. It took several famous mathematicians several months to solve this problem, but Euler finished it in three days with his own invented method. However, due to overwork, he got an eye disease and unfortunately lost his right eye. At this time, he was only 28 years old. At the invitation of Prussian frederick the great, Euler went to Berlin as the director of the Institute of Physics and Mathematics of the Chinese Academy of Sciences until 1768. Later, at the sincere urging of Tsar Cadling II, he returned to Petersburg. Unexpectedly, not long after, his left eye vision decreased and he was completely blind. Unfortunately, the fire in Petersburg in 177 1 affected Euler's residence. 64-year-old Euler was blinded by illness and was trapped in the fire. Although he was saved from the fire by others, his research and a lot of research results were reduced to ashes.
The heavy blow still didn't knock Euler down. He vowed to recover the loss. Before he was completely blind, he could still see vaguely. He seized this last moment, scribbled down the formula he found on a big blackboard, and then dictated its contents, which were recorded by his students, especially his eldest son A. Euler (mathematician and physicist). After Euler was completely blind, he still struggled with the darkness with amazing perseverance and studied it with memory and mental arithmetic.
Euler's memory and mental arithmetic are rare. He can retell the contents of his notes when he was young. Mental arithmetic is not limited to simple operations, and advanced mathematics can also be done by heart. An example is enough to illustrate his skill. Two students of Euler added the term 17 of a complex convergence series to the 50th place, and the difference between them was one unit. In order to determine who is right, Euler calculated all the errors in his mind and finally put them into the errors. It also solved Newton's headache-the problem of starting from the moon and many complicated analysis problems.
Euler has a high style. Lagrange is a great mathematician after Euler. Since the age of 19, he has been communicating with Euler to discuss the general solution of isoperimetric problems, from which the variational method was born. The isoperimetric problem is a problem that Euler has painstakingly considered for many years. Lagrange's solution won warm praise from Euler. 1February 2, 759, Euler praised Lagrange's achievements in his reply. He modestly suppressed his immature works in this respect from being published for the time being, so that the works of young Lagrange could be published and circulated, and won great reputation. In his later years, all mathematicians in Europe regarded him as a teacher. Laplace, a famous mathematician, once said, "Euler is our mentor." Euler's energy was maintained until the last moment, in the afternoon of September 1783. In order to celebrate his successful calculation of the law of balloon rising, Euler invited friends to dinner. Soon after Uranus was discovered, Euler wrote the essentials of calculating Uranus' orbit and made fun of his grandson. After drinking tea, he suddenly fell ill, and his pipe fell out of his hand, muttering "I'm dead". Finally, Euler "stopped living and calculating".
Euler's life is a life of struggle for the development of mathematics. His outstanding wisdom, tenacious perseverance, tireless spirit of struggle and noble scientific ethics are always worth learning. Euler has made brilliant achievements in mathematics, physics, astronomy, architecture, music and philosophy. Formulas, theorems and important constants named after Europe can often be seen in various fields of mathematics. Common textbooks are π( 1736), i( 1777), e( 1748), sin and cos( 1748), tg( 1753) and△ X (. Goldbach conjecture was also put forward in his correspondence with Goldbach. Ole also completed the precise theory of the moon's motion around the earth for the first time, founded the mechanics disciplines such as analytical mechanics and rigid body mechanics, and deepened the design and calculation theory of telescopes and microscopes.
The reasons why Ole can achieve great success in his life are: amazing memory; Concentrate and never be disturbed by noise and murmur; Take your time and be tireless.
Euler was the best mathematician in18th century and one of the greatest mathematicians in history.
1707 On April 5th, Euler was born in Basel, Switzerland. When he was a child, he liked mathematics very much. He began to teach himself algebra when he was below 10. Even several of his teachers haven't read the book, but little Euler read it with relish. When he meets something he doesn't understand, he marks it with a pen and then asks others for advice afterwards. 1720 13-year-old Euler was admitted to university of basel by her own efforts. This was a miracle at that time, which once caused a sensation in the field of mathematics. Little Euler is the youngest student in this university and even in the whole Swiss university campus.
After graduating from Euler University, he went to Petersburg, the Russian capital. At the age of 26, he became a professor of mathematics at the Academy of Sciences in Petersburg. 1735, at the age of 28, Euler struggled for three days and three nights to calculate the orbit of a comet, and finally solved the problem satisfactorily with a new method invented by himself. Overwork made Euler suffer from eye diseases. That year, he lost his right eye. The illness didn't scare him. He worked harder and wrote hundreds of papers and a lot of excellent research results, which made him enjoy a high reputation in the European scientific community. At the age of 59, his vision in his only left eye decreased, and he could only vaguely see objects, and finally he became blind. But work is his life, and he is determined to redouble his efforts to meet the challenge of fate. When he was blind, he dictated, his son recorded and continued to write. Euler worked in the dark for 17 years with his amazing memory and mental arithmetic ability.
1On September 8, 783, Euler, who had just calculated the law of balloon rising not long ago, suddenly stopped breathing with excitement at the age of 76. The three countries where Euler lived and worked: Switzerland, Russia and Germany all regarded Euler as their mathematicians and were proud of him.
Second, science.
Euler, an American born in Hungary, won the prize for his research on the chemistry of carbon cations, because he found a way to keep carbon cations stable. The research field belongs to organic chemistry, and its achievements in hydrocarbons are particularly outstanding. As early as 1960s, he published a large number of research reports and gained a good reputation in the international scientific community. He is an important figure in the field of chemistry. His basic research results have made great contributions to oil refining technology. This achievement has completely changed the research method of carbon cation, an extremely unstable hydrocarbon, and opened a new page for people to understand the cation structure. More importantly, his discovery can be widely used in various industries, from improving oil refining efficiency and producing unleaded gasoline to improving the quality of plastic products and researching and manufacturing new drugs, which plays an important role in improving people's lives.
