Euler's father loved mathematics, and Euler was well influenced by his family since childhood. When I was in college, I met a member of the Jacob Bernoulli family (Swiss, 1654- 1705). When I was 16 years old, I got a master's degree with honors. He was a member of the Petersburg Academy of Sciences and director of the Institute of Physical Mathematics of the Berlin Academy of Sciences. Euler is the most prolific scientist in the field of mathematics. He started writing at the age of 19 until his death at the age of 76. * * * published more than 500 papers and monographs, and there were more than 400 unpublished manuscripts. 1909, the Swiss Academy of Sciences began to publish the complete works of Euler, with a total of 74 volumes, which had not been published in the 1980s. Euler's works are vast, which not only contain scientific thoughts, but also are full of scientific thoughts and thinking processes. They flow into the pen, and the writing is smooth, brilliant and full of literary talent. Therefore, he is known as "Shakespeare in mathematics". Euler is knowledgeable and has a wide range of knowledge. Formulas and theorems named after him can be seen in many disciplines. He has made outstanding contributions to the development of mathematics and other sciences. He learned to educate people, recommended and promoted talents, and his quality was noble, which was admired by future generations.
In astronomical research, 28-year-old Euler lost his right eye in 1735 due to long-term observation of the sun. After that, he was still diligent, his eyesight declined gradually, and he was blind in his left eye at the age of 58 (1766). This scientific old man, who is nearly sixty years old, has lost the light of nature, but has rekindled the lighthouse of the spiritual world. He swore: "If fate is a hard stone, I will turn it into a sledgehammer and smash it to pieces!" " Happiness never comes in pairs, but it never rains alone. 177 1 year, a fire burned most of Euler's books and manuscripts to ashes; 1776, wife died. Repeated blows did not discourage Euler. With extraordinary perseverance, superhuman intelligence, rich knowledge, amazing memory and free mental arithmetic ability, he created thinking through dictation and children's records, and engaged in special scientific research activities that were "unprecedented and unprecedented". Euler's indomitable perseverance and rare memory fascinated the world. For example, in his later years, he can often repeat the notes of his youth. On one occasion, two of his students calculated the sum of the same number composed of 17 respectively, and the result was different by a number in the 50th place. Euler determined their right and wrong through mental arithmetic. During the blind 17 years, the brilliant Euler published more than 400 kinds of papers and monographs, almost half of his life's works. No wonder Newman called Euler "the hero of mathematicians".
Leonhard Euler
(leonhard euler AD 1707- 1783) is also translated as Euler,1the best mathematician in the 8th century and one of the greatest mathematicians in history, and is called "the embodiment of analysis". The famous Swiss mathematician leonhard euler quoted this evaluation.
"Read Euler's original work: in any sense, he is our master." Laplace
1707 was born in Basel, Switzerland. When I was a child, I liked mathematics very much. After 10, I began to teach myself algebra. 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. /kloc-When he was 0/3 years old, he went to university of basel to study, which was a miracle at that time and once caused a sensation in mathematics. Little Euler is the youngest student in this university and even in the whole Swiss university campus. In college, I got the careful guidance of johann bernoulli (1667- 1748), the most famous mathematician in calculus at that time, and gradually established a deep friendship with him. Johann bernoulli later praised shine on you as better than the students in Lanzhou: "When I introduced Advanced Analysis, he was still a child, and you brought him up." Two years later, in the summer, Euler received a bachelor's degree from university of basel, and the following year, Euler received a master's degree in philosophy from university of basel. 1725, Euler began his mathematics career. 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 an award 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.
