Boolean Algebra
Noun · Development
Definitions
A branch of algebra dealing with variables that have two possible values: true/false (1/0). Operations include AND, OR, NOT, XOR, NAND, and NOR. The mathematical foundation of digital circuit design, conditional logic, and database query optimization. Every if-statement is boolean algebra in action.
In plain English: The math of true/false logic that underlies everything from circuit design to if-statements in code.
Example: "Simplify the query condition using boolean algebra — (A AND B) OR (A AND NOT B) reduces to just A."
Etymology
- 1847
- George Boole published 'The Mathematical Analysis of Logic,' founding boolean algebra.
- 1937
- Claude Shannon's MIT thesis showed that boolean algebra could optimize telephone switching circuits, birthing digital circuit design.
