Transformations play an important role in physics. But transformation are more mathematical then physical.

Transformations between inertial systems of reference (download:-)

One can derive the Lorentz transformations without specific using the second postulate of relativity. You can find it in this document: Transformations between inertial systems of reference. Ok it is still a draft:-) Hope you enjoy it! Advertisements

Transformations in Space-Time

What are inertial systems of reference? Why are transformations between inertial systems of reference linear? A simple analysis of transformations between systems of reference. We have two systems of reference, denoted by and . Each system has his own co-ordinates; … Continue reading

The Second postulate of Relativity; what are the implications?

The Second postulate of Relativity states that the speed of light has the same value in any inertial system of reference. The critical question is what is an inertial system of reference? We consider a simple device constructed by a … Continue reading
