Einstein's clocks

One of the most non-intuitive physics theories ever devised is Einstein’s Theory of Special Relativity, which claim such crazy-sounding things as two people disagreeing on such familiar concepts as length and time. In this video, Fermilab’s Don Lincoln shows that every single day particle physicists prove that moving clocks tick more slowly than stationary ones. He uses an example of particles that move for far longer distances than you would expect from combining their velocity and stationary lifetime.
