Boolean algebra

principle · 1854 · Industrial Revolution

The algebra of logic over true/false values; the basis of digital circuits.

Where it is used

• Computer — is used in. Digital circuits implement Boolean logic.
• Relay — is used in. Shannon showed that relay circuits implement Boolean logic.
• Logic gate — is used in. A gate is a Boolean function.

Things built in a similar way

• Binary number system — works like. The 0 and 1 of a binary number correspond to “false” and “true” in Boolean logic.
