Andre Marie Ampere презентация

physicist, mathematician and chemist. He was born in Lyon in the family of a merchant. In his father's beautiful library were works of famous philosophers, scientists and writers. Young André could sit there all day with a book, so that he, who never attended school, was able to acquire extensive and profound knowledge

famous 20-volume "Encyclopedia" by Diderot and D'Alembert, and for three years studied it all. The young man was interested in elegant literature, and he even wrote poetry, but physics and mathematics were much more attractive.

BIOGRAPHY

visit the library of Lyons College. However, many works of great scientists were written in Latin, which he did not know. For several months, Andre independently studied Latin, and works of the classics of science XVII-XVIII centuries. became available to him.

ACHIEVEMENTS

of 12, Ampere had independently figured out the basics of higher mathematics - differential calculus, he had learned to integrate, and at the age of 13 he had already submitted his first work on mathematics to the Lyons Academy!

He begins teaching physics and chemistry, first in Lyon, and two years later at the famous Polytechnic School (Ecole Polytechnique) in Paris. After another 10 years, Amper was elected to the Paris Academy of Sciences, and since 1824 he is a professor at the Normal School (Ecole Normale), the main higher educational institution in Paris

the magnetic needle by Ohrsted became known, Amper devoted himself entirely to the problems of electrodynamics. In the same year he discovered the magnetic interaction of currents, establishes the law of this interaction (later called the Ampere law) and concludes that "all magnetic phenomena are reduced to purely electric effects." According to the Ampère hypothesis, any magnet contains within itself a set of circular electric currents, the action of which explains the magnetic forces.

a coil with a current - a "solenoid". It is Amper who deserves the merit of introducing the terms "electrostatics", "electrodynamics", "electromotive force", "tension", "galvanometer", "electric current" and even ... "cybernetics" into science. Amper proposed to take for the direction of the direct electric current the one in which "positive electricity" moves.

of pneumonia at the age of 61 years. On his tombstone are inscribed the words: "He was just as kind and just as simple as great." The unit of electric current, introduced in 1881, is called the ampere (A) in honor of Andre-Marie Ampere.
