'What do flashlights, the British Invasion, black cats and seesaws have to do with computers -- in CODE, they show us the ingenius ways we manipulate language and invent new ways to communicate with each other. And through CODE, we see how this ingenuity, and our very human compulsion to communicate, have driven the technological innovations of the past two centuries. Using everyday objects and familiar language systems such as Braille and Morse code, the author weaves an illuminating narrative for anyone who's ever wondered about the secret inner life of computers and other smart machines...'
