Relativity Review

• The two basic postulates of the special theory of
  relativity are as follows
• The laws of physics must be the same for all
  observers moving at constant velocity with
  respect to one another.
• The speed of light must be the same for all
  inertial observers, independent of their relative
  motion.

• Galilean transformations must be replaced by the
  Lorentz transformations

Consequences

• Clocks in motion relative to an observer appear
  to be slowed down by a factor ?. This is known
  as time dilation.
• Lengths of objects in motion appear to be
  contracted in the direction of motion by a factor
  of 1/ ?. This is known as length contraction.
• Events that are simultaneous for one observer are
  not simultaneous for another observer in motion
  relative to the first.
