Georges Boole (November 2nd 1815 with Lincoln the United Kingdom - December 8th 1864 with Ballintemple, Ireland) is a logician, Mathématicien and British Philosophe . He is the creator of the Logique traditional, founded on an algebraic structure defining a semantics, and which one calls Boolean algebra in his honor.

He also worked in other fields Mathématiques, differential equations with the Probabilités while passing by the analyzes. Autodidact, it published his first work of Algèbre while exerting his trade of teacher and principal in the area of Lincoln. Its work was worth to him in 1844 the Royal Medal of the Royal Society, then a pulpit of mathematics at the university (Queen' S College) of Cork in 1849.

Biography

Resulting from a poor family, George Boole does not have financial means to go to the university. Its intellectual abilities are however remarkable; only (or almost), he learned the Latin , the German , the French and the Italian . Obliged to work to support its family, it becomes teaching at 16 years.

Four years later, it founds and directs its own school. It is at this time that the young autodidact plunges himself in the study of mathematics to which his/her father had initiated it as of childhood. Profiting from the means of the Institute of mechanics of its city, he confronts himself with works of Isaac Newton, Pierre-Simon Laplace and Joseph-Louis Lagrange. But very quickly, it begins its own research. In 1839, it thus publishes its first study in the Cambridge Mathematical Journal . This publication and the support which it obtains from the circle of the algebrists of Cambridge makes it possible him to be essential gradually like an important personality of the world of mathematics. In 1844, after the publication of a report of analysis in the Philosophical Transactions , the Royal Society decrees a medal to him.

He marries on September 11th, 1835 Mary Everest, niece to sir George Everest, the person in charge of the cartographic mission which baptized the Mount Everest.

It is the beginning of a series of work posing the bases of what one will name later the Boolean algebra. In 1847 Mathematical Analysis Logic leaves off, then An Investigation Into the Laws off Thought, one Which are Founded the Mathematical Theories off Logic and Probabilities in 1854. Boole develops a new form of logic to with it, at the same time symbolic system and mathematics. The goal: to translate ideas and concepts into equation S, to apply certain laws to them and to retranslate the result in logical terms. For that, it creates a binary algebra accepting only two numerical values: 0 and 1. This algebra is defined by the data of a unit E (nonempty) provided with two laws of composition internal (it And it OR) satisfying in certain number of properties (commutation, distributivity…). Work of Boole, if they are theoretical, will not find of them less applications paramount in fields as various as the computing systems, the theory of probability, the electrical circuits and telephone, etc thanks to scientists like Peirce, Frege, Bertrand Russell, Alan Turing and Claude Shannon.

In 1849, George Boole sees himself proposing a pulpit of professor of mathematics in Queen' S College of Cork, in Ireland. And in 1857, it is named member of the Royal Society. It is interested then in the differential equations through two treaties which will have an unquestionable influence: Treatise one Differential Equations (1859) and Treatise one the Calculus off Finite Differences (1860).

George Boole dies of a Pneumonie on December 8th, 1864. It had taken cold after being returned with the College. Believing in the principle of analogy, Mary had confined to bed it and sprinkled water to cure it.

They had five girls:
