Spring-wound clocks from Germany circa 1400 AD were not the earliest devices, which were water clocks from 4000 BC. Many important early devices preceded clocks, including kites from 800 BC, compasses from 400 BC, astrolabes from 150 BC, and the Antikythera mechanism calculator from 100 BC. Throughout history, devices have helped answer profound human questions about understanding the world, finding ourselves, documenting the world, communicating, changing the world, augmenting muscle, healing, augmenting intelligence, and entertaining. People's fundamental needs have remained similar over centuries, and devices should be designed holistically to meet these needs.
