Evariste galois mathematics
Despite this, Galois published three papers in The first of these papers laid foundations for the Galois Theory while the second was about numerical resolution of the equations and the third was about number theory. While many other mathematicians before Galois had already given consideration to what we know as groups, Galois was the very first person to use the term group in the technical sense.

Evariste Galois also introduced the idea of finite field, also called the Galois field. Galois got involved in politics and this led to his expulsion from Ecole Normale. In , Galois quit school and joined the artillery unit of National Guard. He divided his time between mathematics and politics. In the same year, Galois was heading a protest, wearing a uniform of the disabled artillery.
The night before the duel, supposedly fought in order to defend the honor of a woman, he was so convinced of his impending death that he stayed up all night writing letters to his Republican friends and composing what would become his mathematical testament.
Evariste galois quotes: Évariste Galois (born October 25, , Bourg-la-Reine, near Paris, France—died May 31, , Paris) was a French mathematician famous for his contributions to the part of higher algebra now known as group theory.
In his final papers he outlined the rough edges of some work he had been doing in analysis and annotated a copy of the manuscript submitted to the academy. On the 30th of May , early in the morning, he was shot in the abdomen and died the following day at ten in the Cochin hospital probably of peritonitis after refusing the offices of a priest.
His last words to his brother Alfred were: "Don't cry! One of these set down the basis of what would become the Galois Theory, which links field and group theory in abstract algebra.
Another of the papers pioneered the concept of a finite field in number theory. In , France suffered from a great deal of political unrest and instability. In July of that year, the director of the Normale went so far as to lock his students inside the building in order to stop them from joining in a nearby demonstration. Galois was highly critical of this decision in a letter, and this led to his dismissal from the Normale in early January of He was unrepentant, and became a strong supporter of organizations such as the National Guard which championed the cause of republicanism.
Galois continued to work on mathematical problems, but he was becoming more and more committed to the republican cause, to the extent of being arrested for wearing the uniform of the Republican Artillery.

Some historians believe that the cause of the duel may have been related to a woman named Mademoiselle Poterin du Motel, to whom Galois became close. Galois, after reading Abel and Jacobi 's work, worked on the theory of elliptic functions and abelian integrals. However, he learnt in June that the prize of the Academy would be awarded the Prize jointly to Abel posthumously and to Jacobi , his own work never having been considered.
July saw a revolution.

Charles 10 th fled France. Guigniault, locked the students in to avoid them taking part. Galois tried to scale the wall to join the rioting but failed. In December M. Guigniault for his actions in locking the students into the school. For this letter Galois was expelled and he joined the Artillery of the National Guard, a Republican branch of the militia.
In January Galois attempted to return to mathematics. He organised some mathematics classes in higher algebra which attracted 40 students to the first meeting but after that the numbers quickly fell off. Galois was invited by Poisson to submit a third version of his memoir on equation to the Academy and he did so on 17 January.

On 18 April Sophie Germain wrote a letter to her friend the mathematician Libri which describes Galois' situation. Fourier , have been too much for this student Galois who, in spite of his impertinence, showed signs of a clever disposition. He is without money They say he will go completely mad. I fear this is true. Late in 19 officers from the Artillery of the National Guard were arrested and charged with conspiracy to overthrow the government.
They were acquitted and on 9 May republicans gathered for a dinner to celebrate the acquittal. During the dinner Galois raised his glass and with an open dagger in his hand appeared to make threats against the King, Louis-Phillipe. At his trial on 15 June his defence lawyer claimed that Galois had said To Louis-Phillipe, if he betrays but the last words had been drowned by the noise.
Galois, rather surprisingly since he essentially repeated the threat from the dock, was acquitted.
The 14 th of July was Bastille Day and Galois was arrested again. He was wearing the uniform of the Artillery of the National Guard, which was illegal. He was also carrying a loaded rifle, several pistols and a dagger. While in prison he received a rejection of his memoir. Poisson had reported that:- His argument is neither sufficiently clear nor sufficiently developed to allow us to judge its rigour.
He did, however, encourage Galois to publish a more complete account of his work.
