Stone proved in 1936 that every Boolean algebra is isomorphic to a field of sets. For example, the empirical observation that one can manipulate expressions in the algebra of sets, by translating them into expressions in Boole's algebra, is explained in modern terms by saying that the algebra of sets is a Boolean algebra (note the indefinite article). In an abstract setting, Boolean algebra was perfected in the late 19th century by Jevons, Schröder, Huntington and others, until it reached the modern conception of an (abstract) mathematical structure. īoole's algebra predated the modern developments in abstract algebra and mathematical logic it is however seen as connected to the origins of both fields. Leibniz's algebra of concepts is deductively equivalent to the Boolean algebra of sets. History Ī precursor of Boolean algebra was Gottfried Wilhelm Leibniz's algebra of concepts. It is also used in set theory and statistics. īoolean algebra has been fundamental in the development of digital electronics, and is provided for in all modern programming languages. Sheffer in 1913, although Charles Sanders Peirce gave the title "A Boolean Algebra with One Constant" to the first chapter of his "The Simplest Mathematics" in 1880. Īccording to Huntington, the term "Boolean algebra" was first suggested by Henry M. Boolean algebra is therefore a formal way of describing logical operations, in the same way that elementary algebra describes numerical operations.īoolean algebra was introduced by George Boole in his first book The Mathematical Analysis of Logic (1847), and set forth more fully in his An Investigation of the Laws of Thought (1854). Elementary algebra, on the other hand, uses arithmetic operators such as addition, multiplication, subtraction and division. Second, Boolean algebra uses logical operators such as conjunction ( and) denoted as ∧, disjunction ( or) denoted as ∨, and the negation ( not) denoted as ¬. First, the values of the variables are the truth values true and false, usually denoted 1 and 0, whereas in elementary algebra the values of the variables are numbers. It differs from elementary algebra in two ways. In mathematics and mathematical logic, Boolean algebra is a branch of algebra. For other uses, see Boolean algebra (disambiguation).
