Andre marie ampere biography summary example

In mathematics he worked on partial differential equations , producing a classification which he presented to the Institut in This seems to have been a crucial step in his election to the Institut National des Sciences in November when he defeated Cauchy , receiving 28 of the 56 votes cast. In he suggested that an anhydrous acid prepared two years earlier was a compound of hydrogen with an unknown element, analogous to chlorine, for which he suggested the name fluorine.

By he was a strong advocate of a wave theory of light, agreeing with Fresnel and opposed to Biot and Laplace who advocated a corpuscular theory. Orsted's work was reported the Academy in Paris on 4 September by Arago and a week later Arago repeated Orsted's experiment at an Academy meeting. He spoke on his law of addition of electrodynamical forces at the Academy on 6 November and on the symmetry principle in the following month.

There is room to speculate that, without Savary 's aid. Biot , with his assistant Savart , also quickly conducted experiments and reported to the Academy in October This led to the Biot - Savart Law. Another who worked on magnetism at this time was Poisson who insisted on treating magnetism without any reference to electricity.

Poisson had already written two important memoirs on electricity and he published two on magnetism in It is called Memoir on the Mathematical Theory of Electrodynamic Phenomena, Uniquely Deduced from Experience and contained a mathematical derivation of the electrodynamic force law and describes four experiments. We are led to suspect, what, indeed, he tells us himself, that he discovered the law by some process which he has not shown us, and that when he had afterwards built up a perfect demonstration he removed all traces of the scaffolding by which he had raised it.

In later years he devoted himself to studying all fields of knowledge, without dedicating himself exclusively to any as he had done before, but his work was not as forceful as his mathematical and experimental investigations in electricity had been. His remains rest in the Montmartre cemetery in Paris, France. His death occurred decades before electrodynamics was declared the cornerstone of the modern science of electromagnetism.

He succeeded in showing that two parallel cable conductors carrying currents in the same direction have an attractive force for each other. On the contrary, if the current goes in reversed directions they repel each other. This principle states that the mutual action of two sections of cable that carries current is proportional to its length and the intensity of its currents.

Also check the harmony of this principle with the law of magnetic action, formulated by the French physicist Charles Augustin de Coulomb. The result of this surface current, the now known amperian current, is similar to the actual current flowing through a solenoid. This is considered a kind of primitive galvanometer, as it would allow the later development of the instrument that is known today.

Another of his contributions was the determination of the basic unit of electric current that later received his name, the ampere, and the instrument to measure it, the ammeter. In addition, from a series of scientific memoirs and papers, he wrote two treatises on the integration of partial differential equations. Ampere, much later, describes the adolescence years, spent in the lap of nature, as the best time of his life.

Ampere read widely on books written by known authors of those times- Jean Racine, Francois Marie Arouet, also known as the famous Voltaire and the classical poetries of Virgil.

He also showed keen interest in history and politics, especially the ongoing war of American Independence where the French Government provided military support to the American soldiers. Besides classical poetry and literature, he developed keen interest in science at the age of Now aged 12 and with no formal educational background, Ampere completed his academic pursuits in arithmetic, algebra and geometry without following any chronological pattern.

After elaborate research and study, he decided to develop a new division in conics. In mathematics, a conic is a curve obtained as the intersection of a cone with a plane. How incredible! His work primarily laid emphasis on the complex problem of constructing a line of the same length as that of an arc of a circle. He confidently submitted his papers to the Academie de Lyon, but was disappointed as the paper was not published.

Initially the crisis did not affect his home region at Poleymieux much, but by the end of July , the town was drawn into the tentacles of the uprising. The innocent civilians of Lyon rebelled against the authorities, and the entire city was placed under siege. Ampere was deeply anguished by the uncivilized political siege of Lyon.

Eventually after months of civil war, causing widespread destruction of life and property, the city of Lyon was won over by the National Convention. Ampere was shocked beyond words and his whole world fell apart. The death of his father had a devastating effect on the mind of Ampere. The French revolution had traumatized Ampere to such an extent, that he suffered a nervous breakdown.

The profound sorrow and grief at losing his father, by far overshadowed his passion for reading and pursuing academics. Torn apart and in a melancholic state, he would aimlessly wander in the woods and the hills of his countryside home. It was only love that came to his rescue during this misery. Although she found him awkward, shy and poorly presented, the two eventually got married in married The young couple began their marital life in Lyon, and soon Ampere realized the need to be suitably employed.

He began his career as a tutor of mathematics in Lyon at the age of Within a short span of two years, he became a proud father to Jean Jacques and his life was filled with joy and happiness.
