Graphical aids for relativistic optics
Bernhard Rothenstein, Corina Nafornita
The paper presents a relativistic space-time diagram, which displays in true values the space (Cartesian and polar) and the time coordinates of the same event detected from two ine…
Three levels of understanding physical relativity: Galileo's relativity, Up-to-date Galileo's relativity and Einstein's relativity: A historical survey
Bernhard Rothenstein, Corina Nafornita
We present a way of teaching Einstein's special relativity. It starts with Galileo's relativity, the learners know from previous lectures. The lecture underlines that we can have t…
Why p=gamma(v)mv instead of p=mv? Because of the relativistic postulate
Bernhard Rothenstein, Corina Nafornita
It is shown that the addition law of relativistic velocities leads to the fundamental equations of relativistic dynamics.
"An analysis of the classical Doppler Effect"[1] revisited
Bernhard Rothenstein, Corina Nafornita
After having shown that the formula which describes the Doppler effect in the general case holds only in the case of the "very high" frequency assumption, we derive free of assumpt…
