direction with no spatial rotation (i.e., a Lorentz boost in the x direction). The Lorentz transformations are calculated here as linear transformations of four-vectors [ct, x, y, z] described by ...

The Trump administration and El Salvador’s President Nayib Bukele made clear during an Oval Office meeting on Monday that the Maryland man who was wrongly deported to El Salvador won’t be ...

Some crucial results are derived more than once with different approaches: the Lorentz transformation in one spatial direction three times, the Doppler formula four times, the Lorentz transformation ...
