In later life Ampère claimed that he knew as much about mathematics and science when he was eighteen as ever he knew ; but, a polymath, his reading embraced history, travels, poetry, philosophy, and the natural sciences.

Rousseau believed that young boys should avoid formal schooling and pursue instead an “ education direct from nature .” Ampère ’ s father actualized this ideal by allowing his son to educate himself within the walls of his well-stocked library.

The French Revolution ( 1787 – 99 ) that began during his youth was also influential: Ampère ’ s father was called into public service by the new revolutionary government, becoming a justice of the peace in a small town near Lyon.

) Ampère ’ s maturation corresponded with the transition to the Napoleonic regime in France, and the young father and teacher found new opportunities for success within the technocratic structures favoured by the new French emperor.

In September of 1820, Ampère ’ s friend and eventual eulogist François Arago showed the members of the French Academy of Sciences the surprising discovery of Danish physicist Hans Christian Ørsted that a magnetic needle is deflected by an adjacent electric current.

The symbol was used by André-Marie Ampère, after whom the unit of electric current is named, in formulating the eponymous Ampère's force law which he discovered in 1820.

The phenomenon was further investigated by Ampère, who discovered that two parallel current-carrying wires exerted a force upon each other: two wires conducting currents in the same direction are attracted to each other, while wires containing currents in opposite directions are forced apart.

Soon after the discovery in 1820 by H. C. Ørsted that a magnetic needle is acted on by a voltaic current, André-Marie Ampère that same year was able to devise through experimentation the formula for the angular dependence of the force between two current elements .< ref >

Further, Ampère derived both Ampère's force law describing the force between two currents and Ampère's law which, like the Biot – Savart law, correctly described the magnetic field generated by a steady current.

André-Marie Ampère achieved the same results three years later by another method ( in his -- On the Determination of Proportions in which Bodies Combine According to the Number and the Respective Disposition of the Molecules by Which Their Integral Particles Are Made ), but the same indifference was shown to his theory as well.

In classical electromagnetism, Ampère's circuital law, discovered by André-Marie Ampère in 1826, relates the integrated magnetic field around a closed loop to the electric current passing through the loop.

The first commutator-type direct current machine was built by Hippolyte Pixii in 1832, based on a suggestion by André-Marie Ampère.

* Laws of electrodynamics are established by André-Marie Ampère.

Isaac Newton, Adam Smith, André-Marie Ampère, Sewall Wright, Norbert Wiener, Archimedes, and Albert Einstein were all scholars considered to be absent-minded by their contemporaries – their attention absorbed by their academic studies.

Later on acting on a suggestion by André-Marie Ampère other results were obtained by introducing a commutator, which produced a pulsating direct current which at this time was preferable to alternating current.

His mother was a devout woman, so Ampère was also initiated into the Catholic faith along with Enlightenment science.

Through Ampère, Ozanam had contact with leaders of the neo-Catholic movement, such as François-René de Chateaubriand, Jean-Baptiste Henri Lacordaire, and Charles Forbes René de Montalembert.

Ampère ’ s devotion to, and skill with, experimental techniques anchored his science within the emerging fields of experimental physics.

In recognition of his contribution to the creation of modern electrical science, an international convention signed in 1881 established the ampere as a standard unit of electrical measurement, along with the coulomb, volt, ohm, and watt, which are named, respectively, after Ampère ’ s contemporaries Charles-Augustin de Coulomb of France, Alessandro Volta of Italy, Georg Ohm of Germany, and James Watt of Scotland.

Several other experiments followed, with André-Marie Ampère, who in 1820 discovered that the magnetic field circulating in a closed-path was related to the current flowing through the perimeter of the path ; Carl Friedrich Gauss ; Jean-Baptiste Biot and Félix Savart, both of which in 1820 came up with the Biot-Savart Law giving an equation for the magnetic field from a current-carrying wire ; Michael Faraday, who in 1831 found that a time-varying magnetic flux through a loop of wire induced a voltage, and others finding further links between magnetism and electricity.

Gradient estimates were also used crucially in Yau's joint work with S. Y. Cheng to give a complete proof of the higher dimensional Hermann Minkowski problem and the Dirichlet problem for the real Monge – Ampère equation, and other results on the Kähler – Einstein metric of bounded pseudoconvex domains.

In the following year Ozanam was sent to study law in Paris, where he fell in with the Ampère family ( living for a time with the mathematician André-Marie Ampère ), and through them with other leaders of the neo-Catholic movement, such as François-René de Chateaubriand, Jean-Baptiste Henri Lacordaire, and Charles Forbes René de Montalembert.

File: Andre-marie-ampere2. jpg | André-Marie Ampère ( 1777-1836 ): main founder of electrodynamics, showed how an electric current produces a magnetic field, stated that the mutual action of two lengths of current-carrying wire is proportional to their lengths and to the intensities of their currents ( Ampère's law ), namesake of the unit of electric current ( the ampere )

Through popular etymology, it has been falsely claimed that André-Marie Ampère used the symbol in his widely read publications, and that people began calling the new shape " Ampère's and ".

On the other hand, treating all charges on the same footing ( disregarding whether they are bound or free charges ), the generalized Ampère's equation, also called the Maxwell – Ampère equation, is in integral form ( see the " proof " section below ):

Jean-Jacques Ampère ( 12 August 1800 – 27 March 1864 ) was a French philologist and man of letters.

It is named after André-Marie Ampère ( 1775 – 1836 ), French mathematician and physicist, considered the father of electrodynamics.

In 1827 Ampère published his magnum opus, Mémoire sur la théorie mathématique des phénomènes électrodynamiques uniquement déduite de l ’ experience ( Memoir on the Mathematical Theory of Electrodynamic Phenomena, Uniquely Deduced from Experience ), the work that coined the name of his new science, electrodynamics, and became known ever after as its founding treatise.
