Plural of boolean; in computing and logic, values that are either true or false; data types used in programming and mathematical logic.
From George Boole (1815-1864), an English mathematician who developed boolean algebra in the mid-19th century. The '-an' suffix converts the proper name to a common noun, and '-s' creates the plural.
Boolean logic, invented for abstract mathematics, became the fundamental language of computers—every calculation, decision, and operation reduces to true/false choices at the chip level.
