The ABC of Relativity, by Bertrand Russell, Part 2

Let's relax and sleep with more mysteries of relativity, like the speed of light, why time isn't time, and how a fake train robbery reveals that simultaneity doesn't exist. Except when it does.   Raffle Time! Everyone who supports us in November will be entered into a drawing for a personal episode all your own. Whee!
