Does a clock really run slower in a moving frame? Or does it just
*appear* to run slower?
You race your friend around the block on your bicycle. The time it
takes you depends on the frame of reference from which your race is
observed. In which frame is the proper time measured?
The figure demonstrates how the rate of "light clock" depends on the
frame from which it is observed. It runs slower in O's frame than in O
prime's frame. Why is this? What else will "run slower"? Will chemical
reactions run slower? Firing of neurons? Gravity? Explain.
Was there anything that you didn't understand in the reading
assignment? If so, explain.
