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…
A look at Einsteins clocks synchronization
Nilton Penha, Bernhard Rothenstein
While Einstein clocks synchronization process is performed, one has a well defined region in which the clocks are synchronized and another one in which the clocks are not yet synch…
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…
Relativistic electrodynamics as an extrapolation of relativistic kinematics
Bernhard Rothenstein, Stefan Popescu
After having identified all the possible relationships between the electric field and the magnetic field in a given inertial reference frame we derive the transformation equations…
Lorentz transformation directly from the invariance of the speed of light via the addition law of parallel speeds
Bernhard Rothenstein
We show that starting with the addition law of parallel speeds derived as a consequence of the invariance of the speed of light, the Lorentz transformations for the space-time coor…
