An Etymological Dictionary of Astronomy and Astrophysics

Any of a number of possible systems of mathematics that deals with → binary digits instead of numbers. In Boolean algebra, a binary value of 1 is interpreted to mean → true and a binary value of 0 means → false. Boolean algebra can equivalently be thought of as a particular type of mathematics that deals with → truth values instead of numbers.

See also: → Boolean; → algebra. The term Boolean algebra was first suggested by Sheffer in 1913.
