Peer into the structure of a cesium atom to see what makes it ideal for measuring the length of a second and serving as the basis for atomic clocks. Then head into space to learn how GPS satellites use atomic clocks to triangulate positions on the ground. Finally, delve into Einstein's special and general theories of relativity to understand the corrections that GPS must make to stay accurate.
