Albert Einstein was born at Ulm, in Württemberg, Germany, on March 14, 1879. (good bio here)
His Nobel Prize in Physics (1921) was for Einstein's law of the photoelectrical effect. Today, his relativity theory brings his work the most attention. He died in 1955.
Do you use a GPS device? Did you know your cellphone unless it's really old likely has a GPS receiver in it (good thing for E911)?
What does GPS have to do with Einstein?
The system would not work if relativistic effects of the satellites' motion and location were not applied to the setup of the system.
Because of its speed and location the atomic clock on the satellite does not run at the same rate as an atomic clock on the ground. Until I looked up some info on this, I didn't know the location and it's lower gravitational field has the largest relativistic effect that requires adjustment.
So next time you find your way with GPS help - thank Al.
