Scientists have long known that time passes faster at higher elevations, an effect of relativity that has been measured by comparing clocks on the Earth's surface and a high-flying rocket. Now, physicists at NIST have measured this effect at a more down-to-earth scale of about 1 foot, demonstrating for instance that you age faster when you stand a couple of steps higher on a staircase.
