69-563: George Boole Jnr FRS ( / b uː l / ; 2 November 1815 – 8 December 1864) was a largely self-taught English mathematician , philosopher and logician , most of whose short career was spent as the first professor of mathematics at Queen's College, Cork in Ireland. He worked in the fields of differential equations and algebraic logic , and is best known as the author of The Laws of Thought (1854), which contains Boolean algebra . Boolean logic, essential to computer programming ,
138-505: A rational function . Among other results, he proved what is now called Boole's identity: for any real numbers a k > 0, b k , and t > 0. Generalisations of this identity play an important role in the theory of the Hilbert transform . In 1847, Boole published the pamphlet Mathematical Analysis of Logic . He later regarded it as a flawed exposition of his logical system and wanted An Investigation of
207-429: A Boolean algebra structure on equivalent statements of a propositional calculus is credited to Hugh MacColl (1877), in work surveyed 15 years later by Johnson. Surveys of these developments were published by Ernst Schröder , Louis Couturat , and Clarence Irving Lewis . In 1921, the economist John Maynard Keynes published a book on probability theory, A Treatise of Probability . Keynes believed that Boole had made

In 1861, Boole was involved in a Judgement in the Court of Queen's Bench in Ireland against one John Hewitt Wheatley of Craig House, Sligo for the sum of £400, whereby Wheatley's estate and interest in lands of Maghan/Mahon, County Cork became vested in Boole. In March 1863, Boole leased Litchfield Cottage, Cork, the house in which he would live with his wife Mary until his death in December of
414-547: A few others, but nearly all the logicians and mathematicians ignored [953] the statement that the book was meant to throw light on the nature of the human mind; and treated the formula entirely as a wonderful new method of reducing to logical order masses of evidence about external fact. Mary Boole claimed that there was profound influence – via her uncle George Everest – of Indian thought in general and Indian logic , in particular, on George Boole, as well as on Augustus De Morgan and Charles Babbage : Think what must have been
483-587: A fundamental concept in binary logic, which laid the groundwork for the algebra of logic tradition and forms the foundation of digital circuit design and modern computer science. Boole also attempted to discover a general method in probabilities, focusing on determining the consequent probability of events logically connected to given probabilities. His work was expanded upon by various scholars, such as Charles Sanders Peirce and William Stanley Jevons. Boole's ideas later gained practical applications when Claude Shannon and Victor Shestakov employed Boolean algebra to optimize
552-534: A fundamental error in his definition of independence which vitiated much of his analysis. In his book The Last Challenge Problem , David Miller provides a general method in accord with Boole's system and attempts to solve the problems recognised earlier by Keynes and others. Theodore Hailperin showed much earlier that Boole had used the correct mathematical definition of independence in his worked out problems. Boole's work and that of later logicians initially appeared to have no engineering uses. Claude Shannon attended

Sometimes, in discoursing of men we imply (without expressing the limitation) that it is of men only under certain circumstances and conditions that we speak, as of civilised men, or of men in the vigour of life, or of men under some other condition or relation. Now, whatever may be the extent of the field within which all the objects of our discourse are found, that field may properly be termed
690-463: A paper on early invariant theory and "The Mathematical Analysis of Logic," which introduced symbolic logic. Boole also wrote two systematic treatises: "Treatise on Differential Equations" and "Treatise on the Calculus of Finite Differences." He contributed to the theory of linear differential equations and the study of the sum of residues of a rational function. In 1847, Boole developed Boolean algebra,
759-707: A philosophy class at the University of Michigan which introduced him to Boole's studies. Shannon recognised that Boole's work could form the basis of mechanisms and processes in the real world and that it was therefore highly relevant. In 1937 Shannon went on to write a master's thesis, at the Massachusetts Institute of Technology , in which he showed how Boolean algebra could optimise the design of systems of electromechanical relays then used in telephone routing switches. He also proved that circuits with relays could solve Boolean algebra problems. Employing

The second part of the Laws of Thought contained a corresponding attempt to discover a general method in probabilities . Here the goal was algorithmic: from the given probabilities of any system of events, to determine the consequent probability of any other event logically connected with those events. In late November 1864, Boole walked, in heavy rain, from his home at Lichfield Cottage in Ballintemple to

He received a primary school education and learned Latin and modern languages through various means. At 16, he began teaching to support his family. He established his own school at 19 and later ran a boarding school in Lincoln. Boole was an active member of local societies and collaborated with fellow mathematicians. In 1849, Boole

1449-883: The Lincoln Mechanics' Institute , in the Greyfriars, Lincoln , which was founded in 1833. Edward Bromhead , who knew John Boole through the institution, helped George Boole with mathematics books and he was given the calculus text of Sylvestre François Lacroix by the Rev. George Stevens Dickson of St Swithin's, Lincoln . Without a teacher, it took him many years to master calculus. At age 19, Boole successfully established his own school in Lincoln: Free School Lane. Four years later he took over Hall's Academy in Waddington , outside Lincoln, following

Contrary to widespread belief, Boole never intended to criticise or disagree with the main principles of Aristotle 's logic. Rather he intended to systematise it, to provide it with a foundation, and to extend its range of applicability. Boole's initial involvement in logic
