Fundamentals of Special Theory of Relativity

1

Was ist die Lichtgeschwindigkeit?

Hier lernst du einige Fakten über die Lichtgeschwindigkeit und das Licht, wie zum Beispiel, wie damit ein Meter definiert wird.

Here you will learn all about Minkowski diagrams, which are used to visualize special relativity (e.g. length contraction, time dilation).

3

With the help of a light clock, the deceleration of time in the moving system can be derived by using only Pythagoras' theorem.
