Branch of Science Mathematicians Nationality English Boole, George (1815-1864) English mathematician who was the author of several classic works on mathematical logic As a child, he taught himself Latin and Greek in the belief it would enable him to rise above his wretched lower-class existence. He spent four years teaching at elementary schools, at which time he studied and on his own. Following this, he discovered the usefulness of invariants. His most important work was in the separation of symbols from operations and creation of mathematical logic In the works The Mathematical Analysis of Logic (1847) and Investigation of the Laws of Thought (1854) he established formal logic and Boolean algebra (the algebra of sets). In Treatise on Differential Equations (1859), he pointed out parallels between differential operators and the rules of algebra. References Bell, E. T. "Complete Independence: Boole."

George Boole One of the founders of symbolic logic, i.e. the logic expressed in terms of algebraic operations. De Morgan and he published their books on symbolic logic almost at the same time in 1847. Boole's Mathematical Analysis of Logic clearly presents his idea that the same symbolic system of algebra can express both Aristotelian syllogism and Stoic propositional logic, if we change the interpretation of symbols. However, his algebraic method was still poor as regards quatification, i.e. the logic of "all" and "some". Boole also contributed to the algebraic basis of probability theory.

Boole, am 2. November in Lincoln in England geboren, eignete sich sein Fachgebiet, die Mathematik, in jahrelangem Selbststudium an. Sein Werk "Mathematische Analyse der Logik" führte die Mathematik von ihrer zweckgebundenen Zielsetzung hin zu einem abstrakten System mit allgemein anwendbaren logischen Gesetzen. Die nach ihm benannte "Boolsche Algebra" und seine daraus abgeleitete formale Logik bilden die Grundlage der abstrakten wissenschaftlichen Beweisführung und sind heute unter anderem eine Grundlage der Computerprogrammierung. wurde die Leistung des Autodidakten mit einer Professur an der Universität Cork belohnt.

His work The Mathematical Analysis of Logic 1847 established the basis of modern mathematical logic, and his Boolean algebra can be used in designing computers. Boole was born in Lincoln and was largely self-taught. In 1849 he was appointed professor of mathematics at Queen's College in Cork, Ireland. In 1847 he announced that logic was more closely allied to mathematics than to philosophy. He argued not only that there was a close analogy between algebraic symbols and those that represented logical forms but also that symbols of quantity could be separated from symbols of operation. These ideas received fuller treatment in An Investigation of the Laws of Thought on which are Founded the Mathematical Theories of Logic and Probabilities Helicon Publishing LTD 2000.

His work The Mathematical Analysis of Logic (1847) established the basis of modern mathematical logic, and his Boolean algebra can be used in designing computers. Boole's system is essentially two-valued. By subdividing objects into separate classes, each with a given property, his algebra makes it possible to treat different classes according to the presence or absence of the same property. Hence it involves just two numbers, and 1 the binary system used in the computer.

document.write(""); BOOLE, GEORGE In the course of the 16th and 17th centuries the Low Countries for a time became the chief centre of the bookselling world, and many of the finest folios and quartos in our libraries bear the names of Jansen, Blauw or Plantin, with the imprint of Amsterdam, Utrecht, Leiden or Antwerp, while the Elzevirs besides other works produced their charming little pocket classics. The southern towns of Douai and St Omer at the same time furnished polemical works in English. Under PUBLIShING are noticed various further developments of this subject. Much interesting information on the history of the book trade will be found in Charles Knight’s Biography of William Caxton, and in the same author’s Shadows of the Old Booksellers (f 865). See also Henry Curwen, history of Booksellers (1873); and Heinrich Lempertz, Bilder-Hefte zur Geschichte des Bücherhandels (Cologne, 1854). Only two systematic treatises on mathematical subjects were completed by Boole during his lifetime. The well-known During the last few years of his life Boole was ‘constantly engaged in extending his researches with the object of producing a second edition of his Differential Equations much more complete than the first edition; and part of his last vacation was spent in the libraries of the Royal Society and the British Museum. But this new edition was never completed. Even the manuscripts left at his death were so incomplete that Todhunter, into whose. hands they were put, found it impossible to use them in the publication of a second edition of the original treatise, and wisely printed them, in 1865, in a supplementary volume.
