The more I visualize the four dimensional coordinate system (x, y, z, t), the more I realize just how utterly relativistic, or inertial, it is. The missing dimension from...

Sometimes relativity textbooks are written by Einstein's zombies, not by Einstein's hypnotists, and in such cases one can find unforgettable texts. For instance, Einstein's...

It is known that all light sources moving relative to us exhibit a "Doppler shift." The wavelength seems to get shorter or longer. There could be two explanations for...
