Homework Help: Train synchronize relativity problem

  1. Sep 26, 2010 #1
    1. The problem statement, all variables and given/known data

    Consider four clocks at different locations in train: A and D at two ends, B and C midway between the center and A and D respectively. How can a people standing at the center of the train synchronize all four clocks with a mirror M which he can install beforehand at arbitrary positions inside the train?
