We have just added a new tab in Minkowski space time article Minkowski's Four-Dimensional Space-Time, which shows how to retrieve the Lorentz factor = time dilation factor from the spacetime interval invariance.
So far, we have then deduced the time dilation factor by 3 different ways:
- by simple geometry and the light clock example Constant Speed of light - Introduction to Time Dilation and Lorentz factor
- by the Minlowski space time interval invariance Minkowski's Four-Dimensional Space-Time
- and finally by using the Lorentz transformation equations The Lorentz transformations Part III - Measuring-Rods and Clocks in motion
