OK, Spirit, you looked at Lesson 42: The Lorentz Transformation.
Now if the speed of light is to be the same for all inertial observers (as indicated by the Michelson-Morley experiment) the equations for time and space are not difficult to find. But what do they mean? They mean that the length of a meter stick, or the rate of ticking of a clock depends on who measure it.
o Can you use the Lorentz Transformation to work problems relating time or space intervals in different reference frames?
o Can you give some of the hypothetical explanations put forward to account for the Michelson-Morley experiment?
o Can you discuss the concept of length contraction?
o Can you understand and use spacetime diagrams?
o Can you define and discuss the concept of simultaneity?
o Can you define and discuss clock synchronization?
Spirit, If you can't do these things, then you don understand the relevant material related to the Lorentz Transform.
