ladder of abstraction, the ability to assemble increasingly complex systems.
decimal representations of numbers – like those represented by teeth on a gear
Binary - on/off, true/false, 1/0, - (ternary, quinary, ...) - gives us the most distinct signal
Another reason computers use binary is ... It's called Boolean Algebra!
George Boole, “The Mathematical Analysis of Logic” in 1847.
in Boolean Algebra: a NOT, an AND, and an OR operation.
logic table.
we can easily build boolean logic out of transistors.
