Relativistic dynamics without collisions and conservation laws

Bernhard Rothenstein, Stefan Popescu

We show that the relativistic expressions for momentum and energy as well as the way in which they transform could be derived without involving collisions and conservation laws. Ou…

Nonstandard Lorentz-Einstein transformations

Bernhard Rothenstein, Stefan Popescu

The standard Lorentz transformations establish a relationship between the space-time coordinates of the same event when detected from two inertial reference frames I and I' in the…

Lorentz transformation, time dilation, length contraction and Doppler Effect - all at once

Bernhard Rothenstein, Stefan Popescu

We present a simple derivation of the Lorentz transformations for the space-time coordinates of the same event. It is based on the relative character of length and time interval as…
