Thus with the help of certain imaginary physical experiments we have settled what is to be understood by synchronous stationary clocks located at different places, and have evidently obtained a definition of “simultaneous,” or “synchronous,” and of “time.” The “time” of an event is that which is giv ...

Relativistic Quantum Mechanics

Here we will follow his idea in a qualitative way just to get the main concept across. First, we note that Lorentz transfor ...
