1775 65438+1October 22nd, Ampere was born in a wealthy family in Lyon. Ampere is a mathematical wizard. He learned the basics of mathematics when he was very young. /kloc-began to learn calculus at the age of 0/2, and 18 can repeat some calculations in Lagrangian analytical mechanics. At the age of 24, he began to teach mathematics in Lyon and began to study mathematics systematically. Later, he wrote a paper on probability theory, which not only aroused widespread concern in society, but also laid a solid mathematical foundation for his research on electromagnetism.
Ampere's most important achievements focus on the research of electromagnetic action from 1820 to 1827. During these seven or eight years, Ampere discovered the interaction law of current, put forward the right-hand rule (later named Ampere rule), invented the galvanometer, and summarized a series of major breakthroughs such as Ampere rule. Through his efforts, electromagnetism has become infinitely open, just like seeing the sun through clouds.
In such a short time, Ampere can achieve such great results, which is rare in the history of science, which is of course inseparable from his diligence. He is not only diligent in his work, but also devoted to it, even to the point of forgetting himself. It is said that once, on the way to the school where he taught, Ampere was thinking about an electrical problem while walking. When crossing the Seine, he picked up a pebble and put it in his pocket. After a while, he took out the "stone" and threw it into the river. When he got to school, he walked into the classroom and habitually took out his pocket watch to look at the time, only to find that he took out a pebble and threw it into the Seine River.
There is a wider story about his selfless thinking. Once, Ampere was walking in the street and came up with a formula for an electrical problem, but he was worried because he couldn't find a place to calculate it. Suddenly, he found a "blackboard" in front of him, so he couldn't wait to take out the chalk and calculate on it. It turns out that the "blackboard" is the back of a car. The carriage moved, and he followed, writing while walking; The carriage was getting faster and faster, and he began to run, intent on completing his deduction. Only when he really couldn't catch up with the carriage did he stop and look disappointedly at the "blackboard" in the distance, but he didn't notice the passers-by who were laughing their heads off.
1827, Ampere integrated his research on electromagnetic phenomena into the book Mathematical Theory of Electrodynamics. This is an important classic work in the history of electromagnetism, which has a far-reaching impact on the future development of electromagnetism. Maxwell praised the research work of Ampere as "one of the most brilliant achievements in science" and also praised Ampere as "Newton in electricity".
Ampere's achievements are manifold, and he has also made many contributions in mathematics and chemistry. He has studied probability theory and integral partial differential equations. He and David knew the elements chlorine and iodine almost at the same time, demonstrated the relationship between volume and pressure at constant temperature, and tried to find the classification and arrangement order of various elements.
1836, 10 In June, Ampere died of acute pneumonia in Marseille at the age of 6 1 year. In order to commemorate his outstanding contribution to electromagnetism, later generations named the unit of current "ampere".
