Let's make it practical. Where do you see Boolean algebra? Everywhere. Your Calculator: The circuit that adds two numbers is built using XOR and AND gates in an arrangement called a "half-adder," based entirely on Boolean logic. Your Smartphone: The touchscreen interface uses logic to determine if a touch is a tap, swipe, or pinch. The memory that stores your photos is a vast array of circuits that can be in a 1 or 0 state. Your Car: The anti-lock braking system (ABS) uses sensors and logic circuits to decide when to pulse the brakes to prevent skidding. Your Home: A simple thermostat: IF (temperature < setpoint) AND (power is ON) THEN turn on heater. This is a Boolean statement.It is the invisible logic that governs the behavior of nearly every modern electronic device. It's the reason we can program machines to make decisions based on input conditions.
