Eager for a mathematical formula
If we want to say that China has made the greatest contribution to the knowledge points of mathematics from primary school to university, it is not comparable to Euramo.

Euler was a born genius. Yes, he is not only a genius in mathematics, but also proficient in various fields. He never dared to write novels like this in his life. It's really against the sky

At the age of 9, he finished reading Newton's Mathematical Principles of Natural Philosophy. /kloc-was admitted to university of basel at the age of 0/3. At first, he majored in philosophy and law, which caused a sensation in the mathematics field at that time. Euler is the youngest student in this university and the whole Swiss university campus.

Euler, who is studying in college, thinks it's too easy to major in philosophy and law. I went to math, theology, Hebrew and Greek at one go.

After school, I also study music, physics and architecture. In this way, he still felt that he had a leisurely life. He has only been in college for two years. He has been studying six majors and then got a master's degree. I read a master's degree in 1 year and got a doctor's degree. My doctoral thesis is about physics. ......

/kloc-When I was 0/9 years old, I wanted to apply for a physics professor in university of basel. Yes, that's right. I 19 years old, but I was rejected. You are not a physics major. If you are good at physics, do you want to be a professor?

However, university of basel didn't want it. The Royal Academy of Sciences in St. Petersburg, Russia, successfully made Euler a professor of physics. Euler went to Russia and had a great influence in Russian academic circles. He laid the foundation of the Moss School of the Soviet Union, and the Moscow School was the core supporting force for the rise of the Soviet Union.

At the age of 20, Euler took part in the prize competition of the Paris Academy of Sciences, and she won the second prize. At that time, the first prize was the leader of the scientific community? Father of shipbuilding engineering? Pierre? Bug. However, Euler was still unconvinced. In the next 12, all the prizes in the quiz were won by Euler.

I feel that every time I participate in the competition, the referee will say:? When Euler comes, there is no need to compete for the championship. Then let's compete for the second place. Euler, why don't you just take the trophy and go home, so as not to waste time. ?

At the age of 27, he invented a series of symbols that had a far-reaching impact on mankind? , function symbol f(x), triangle symbol sin, cos, tg, symbol? Wait, he invented all this.

4 1 year-old published Introduction to Infinite Analysis, which is called the embodiment of analytical science. Introduction to Infinite Analysis (I) occupies a prominent position in the history of mathematics and is one of the seven masterpieces that have the greatest influence on the development of mathematics.

He unified these symbols and made trigonometry a systematic science. He first defined trigonometric function by ratio, and then linked trigonometric function with exponential function.

Euler put the function in the center for the first time, and it was based on the differential of the function. The definition of function he gave in this book is:? The function of a variable is an analytic expression, which is composed of this variable and some constants in any way? .

It can be said that more than half of the mathematical symbols we used in high school, as well as the exponential function and trigonometric function we learned, are related to Euler.

However, this is only a little Weibo contribution made by others. It hurts primary and secondary school students. Can I enlarge the students' walk? From Euler line of elementary geometry, euler theorem of polyhedron, Euler transformation formula of solid analytic geometry and Euler solution of quartic equation to Euler function of number theory, Euler equation of differential equation, Euler constant of series theory, Euler equation of variational method and Euler formula of complex variable function, Euler can be said to have left footprints in every field of mathematics and contributed a lot of knowledge to countless college students.

Euler actually ruled mathematics in the18th century; For calculus, a new branch of mathematics at that time, he deduced many results. Many branches of mathematics were founded by Euler or made great progress. Even in our information age, they are still influenced by his Hui Ze. RSA public key cryptography algorithm widely used in computer field is also based on Euler function.

Of course, Euler not only harmed the students of mathematics department, but at the age of 32, he didn't cross the line for a long time, and his heart itched, so he published a book on music theory and founded rigid body mechanics and fluid mechanics by the way. Of course, the world is still the pioneer of the stability theory of elastic systems.

However, perhaps because of too many bugs, Euler lost his right eye at the age of 3 1 and his eyes at the age of 59.

As a prolific man in the history of science, the most prolific outstanding mathematician in the history of science, according to statistics, he wrote 886 books and papers in his tireless life, among which analysis, algebra and number theory accounted for 40%, geometry for 18%, physics and mechanics for 28%, and astronomy for1kloc-0/%.

This is the result of his blindness and the fire at home. 177 1 year, 64-year-old Euler was trapped in a fire in Petersburg. Although people were rescued, all the research results were burned.

However, the unforgettable Euler said, it doesn't matter, it's all in my head. How powerful is Euler's brain? His memory even reached the point where he never forgets anything. He can recite Virgil's epic Aeneas, which he read when he was young. How thick is this book? The Chinese version translated by People's Publishing House has more than 300 pages. He can point out what the first and last lines of each page of the version he recited are. .

Although he is blind, his mental arithmetic ability is amazing. 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. Euler, a blind man, found this mistake only by mental arithmetic.

So after the fire, quite a part of Euler was rearranging the results destroyed by the fire. He was dictated by his students, especially his eldest son, A? Euler (mathematician and physicist) pointed out that with the help of clerks, Euler's research in many fields actually became more effective. 1775, he finished a math paper every week on average. On the one hand, rearranging the burnt results is not human behavior, on the other hand, it is producing new results. . .

However, even though Euler fought for 13 years, he still sorted out a small number of charred results. The four greatest mathematicians in the history of mathematics are Archimedes, Newton, Euler and Gauss.

Euler is the most versatile one and is known as a generalist beyond Leonardo da Vinci. Euler has made many great achievements in humanities and natural sciences.

In particular, his Euler formula is very simple, but it is called the first formula in the universe. This formula has influenced the development of the whole mathematics. Trigonometric function, Fourier series, Taylor series, probability theory, group theory, geometry and even physics are all influenced by this formula. The theoretical basis of mechanical wave theory, electromagnetism, wave optics, quantum mechanics and so on, which triggered the electronics revolution, is also included.

Gauss once said:? A person who sees this formula for the first time and doesn't feel its charm can't become a mathematician. ?
