Special relativity and time
More about simultaneity, time dilation and the famous case of the travelling twin
A simple thought experiment with light clocks – clocks in which light keeps stroke – allows the derivation of time dilation.
Why it is necessary to define simultaneity, and how best to go about defining it.
How you can picture the relativity of simultaneity and time dilation, using a simple geometric analogy
Why the so-called “twin paradox” isn’t really a paradox
How one can picture the situation of the travelling twin, using a simple geometric analogy
