George
Boole (English, 18151864)
invented Boolean algebra, the
mathematical foundation of the
logic used by the digital computer.
In particular, computers use the
special case of Boolean logic
where entities can have only two
values (e.g. 1 or 0, the binary
system) and a set of clear rules
defines their operations.
“If X
is true and Y
is false, or X
is true and W is true, then Z
is true” is a typical decision
that computer programs make. In
Boolean mathematical form, this
decision would look like:
