A Minor History of / Time Without Clocks
But while nature may mete out time’s passage in these horological devices, it takes human observation of the heavens to set them. Even the most precise atomic clock must be periodically tweaked to account for variations in the earth’s rotation. Some clocks, however, are tuned more directly to nature.
