November 2. The foundations of electromagnetism had been laid. By placing, with the physicist Arago, a soft iron core in the centre of a helix, which he baptised solenoid, he invented the temporary magnetisation that is the basis for the electromagnet. It rotated a permanent magnet through which a current would flow prefiguring the electric motor.

In Novemberat the 26th General Conference on Weights and Measures CGPMthe Ampere was confirmed as the unit of electric current and one of the seven fundamental units of the international system.

Its definition has changed and is now based, as with all other fundamental units, on universal constants. After having been, until May 20,based on the electrodynamic forces between conductors, the Ampere is now distinctly defined from the definition of the elementary charge of one electron and the second. This new definition makes it possible to implement new realization methods, including quantum technologies, and to achieve accuracies approximately 10 times more precise.

He describes this education in autobiographical writings rather strangely referring to himself in the third person :- His father, who had never ceased to cultivate Latin and French literature, as well as several branches of science, raised him himself in the country near the city where he was born.

He never required him to study anything, but he knew how to inspire in him a desire to know. This work attempted to solve the problem of constructing a line of the same length as an arc of a circle. He repeated all the calculations in it However his life was soon to be shattered. The French Revolution began with the storming of the Bastille on 14 July but the effect on the Poleymieux region was not very great at first.

The city of Lyon refused to carry out instructions from Paris and the city was besieged for two months. He only returned to something like his old self when he met a girl, Julie, whom he fell deeply in love with. He married Julie in and their son Jean-Jacques was born in This research resulted in him composing a treatise on probabilityThe Mathematical Theory of Gameswhich he submitted to the Paris Academy in This work was followed by one on the calculus of variations in His time spent in Lyon had been made difficult due to the continuing decline in his wife's health.
