Title:
Einstein's Relativity and Everyday Life
Description:
If you rely on a GPS to navigate, then you need Einstein's theories of relativity--special relativity because the GPS satellites are moving fast relative to you, and general relativity because the GPS satellites are in a different gravitational field than you are. Without correction for relativistic effects, errors in GPS positions would increase by 10 km for every day the system operates!
