Simple SR question

  1. Feb 3, 2005 #1
    What if I am in a RF, S, anchored to the ground, and there is another RF S', which is anchored to a train. According to my RF, the clocks in the train moves slower, but according to S', does my clocks move slower too?

    Yup, and by exactly the same amount. Likewise, you see rulers on the train shrunk relative to your rulers, and an observer on the train sees your rulers shrunk relative to rulers on the train.
