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

Quotes

"The essence of my theory is precisely that no independent properties are attributed to space on its own. It can be put jokingly this way. If I allow all things to vanish from the world, then following Newton, the Galilean inertial space remains; following my interpretation, however, nothing remains.."
Letter from A.Einstein to Karl Schwarzschild - Berlin, 9 January 1916

"Quantum mechanics is certainly imposing. But an inner voice tells me that it is not yet the real thing. The theory says a lot, but does not really bring us any closer to the secret of the 'old one'. I, at any rate, am convinced that He is not playing at dice."
Einstein to Max Born, letter 52, 4th december 1926
