Plum endurance

(The following is the classical Chinese version)

Ampere, also from Lyon, France. My family has been rich since childhood. His father, a man of insight, built a private library for him with a rich collection of books. An Jun lived up to expectations and read widely, especially like natural science, mathematics and philosophy. Twelve years, self-tapping differential; When I was fourteen, I read Dion's encyclopedia. The achievement of a lifetime begins here.

Throughout Angu's life, he generally spent his time in study, teaching and scientific research. Dedicated and admirable. There are two stories, both of which are dedicated to my heart.

One is to move the blackboard. One day, Angu was walking in the street. Suddenly, an electrical formula came to mind and there was nowhere to write. A blackboard suddenly appeared in front of me, so I took the chalk I carried with me and wrote it quickly. Unexpectedly, the blackboard went forward. Angu wrote books one by one, and the blackboard went farther and farther, but it was not so well written. An Jun looked at it and sighed. On closer inspection, it is the back wall of a carriage. Passers-by all laughed.

One: pocket watches become pebbles. Angu entered the school to teach and crossed the Seine. Take a pebble from the river and put it in your arms. Spin, take pebbles out of your arms and throw them back into the river. When I walked into the classroom, I picked up my pocket watch and found pebbles. Wu Fang is a pocket watch. He jumped into the river before. The students also laughed.

It goes without saying that Angu has made outstanding achievements by focusing on this point. Guan's achievements in electromagnetic research have been spread all over the world. Maxwell called it "Newton in electricity". The unit of current is also named after its surname.

Yu, a junior high school physics teacher, also. It is often said that Ampere teaches disciples. An Jun also has enough food and clothes for his parents, so he wrote this article to study.

Ampere is a Frenchman in Europe, but his achievements have enabled him to transcend national boundaries. Yu said to his disciples: Ampere is not the ampere of a country or a continent, but the ampere of all mankind. Great angu!

(The following is the vernacular version)

Anyone who has studied junior high school physics will be familiar with the word ampere, and the unit of current is named after the surname ampere. Know its name, not necessarily. Let me briefly introduce amperes first.

First, the basic information:

Ampere, whose full name is André-Marie Ampère, is a famous French physicist, chemist and mathematician. Born in Lyon, the third largest city in France, his family is rich.

An Pei was born in A.D. 1775, which was forty years of the Qing Dynasty in China. He died in a.d. 1836, the 16th year of Qing Daoguang in China. It can be seen that Ampere basically lived in China in the middle of Qing Dynasty. During the Daoguang period, the Opium War broke out in China, and the national situation declined day by day. Almost at the same time, Ampere has made great contributions to modern science, and Europe is also booming. It's really emotional to think about it.

Second, love learning:

Ampere's father was deeply influenced by Russo's educational theory, especially by setting up a rich private library for Ampere. The children of the rich are not necessarily playboys. Ampere has read widely since he was a child. 12 years old taught himself differential operation and various math books, and 14 years old learned the encyclopedia edited by Diderot and D 'Alembert.

It can be seen that he especially likes natural science, mathematics and philosophy. He has shown a unique and outstanding side since he was a child.

Third, life orientation:

1802, 27-year-old Ampere was a professor of physics and chemistry at Bourjean-Bryce Central School.

1808, 33-year-old Ampere was appointed as the chief invigilator of Imperial University of France;

18 14 years, 39-year-old ampere was elected as a member of the Department of Mathematics of Imperial College London;

18 19, 44-year-old Ampere gave a philosophy lecture at the University of Paris;

1824, 49-year-old Ampere is a professor of experimental physics at the French Academy.

It can be said that Ampere spent his whole life in teaching and scientific research.

Fourth, concentrate on scientific research:

Ampere's performance in scientific research can be described as "concentration". In this regard, there are two stories worth listening to.

1, move the blackboard:

This story is the most popular and once appeared in the text of junior high school English textbooks. The plot is as follows:

Once, Ampere was walking in the street. Most people see handsome men and beautiful women in the street. Unlike Ampere, he is thinking about scientific problems. Suddenly, he thought of an electrical formula and wanted to find a place to do it, but there was no place to do it in the street! Ampere is worried. When he saw a blackboard, he was ecstatic. He immediately ran to the blackboard and took out the chalk he carried with him. Look at the quality! -Can't wait to calculate.

Counting, something strange happened: the blackboard moved forward. Ampere also forgot to consider the reason. His mind is full of his electrical formulas, so he walks and writes along with the blackboard. Helpless, the blackboard moves faster and faster. Finally, he really couldn't keep up, so he stopped to take a closer look: it turned out that this was not a blackboard at all, but the rear of a carriage.

Ampere sighed and said, "That's too bad. It's almost over. " Pedestrians nearby couldn't help laughing their heads off when they saw this strange scene.

2, pocket watch into pebbles:

Once, Ampere went to work in the school where he taught. I walk slowly because I am absorbed in thinking. On the way, you have to pass through the Seine, a famous river in France. By the Seine, he picked up a pebble and put it in his pocket. After a while, he took out pebbles and threw them back into the Seine.

Come to school and walk into the classroom. He habitually took out his pocket watch from his pocket and looked at the time. What he took out was a pebble. It turned out that he threw his pocket watch into the Seine. Seeing the teacher's behavior, the students couldn't help laughing.

Verb (abbreviation of verb) main contribution:

Ampere's main scientific contribution is in electromagnetism. His main work in electromagnetism is the mathematical theory of electrodynamics, which is one of the important classics of electromagnetism. Maxwell, a British physicist and mathematician, praised Ampere's work as "one of the most brilliant achievements in science" and also praised Ampere as "Newton in electricity".

Ampere was also the first person to develop the technology of measuring electricity. He made an instrument for measuring current with an automatic rotating magnetic needle, which was called "galvanometer" after improvement. So the ammeter in junior high school physics textbook was once called "ammeter".

Science knows no borders. Ampere belongs to France and the world. Let's pay high tribute to Ampere!
