In the first lecture of the course Professor Susskind introduces the original principle of relativity - also known as Galilean Invariance - and discusses inertial reference frames and simultaneity. He then derives the Lorentz transformation of special relativity following the method in Einstein's original paper [check this], and introduces length contraction and time dilation, invariants, and space- and time-like intervals.

  • Simultaneity
  • Derivation of the Lorentz transformation
  • Speed of light is independent of reference frame
  • Length contraction and time dilation
  • Invariant intervals
  • Space-like and time-like intervals
