How do you adjust two clocks located in different places to each other? By communication established between the two people responsible for the adjustment. However, there is no instantaneous communication; and, since all transmission takes time, we had to choose … Read More

More generally, let us still call S a system immobile in the ether, and S’ a double of this system, which first coincided with it and then detaches itself in a straight line with the speed v. While S’ contracts … Read More

Here then is the explanation proposed by Lorentz, an explanation of which another physicist, Fitzgerald, also had the idea. The line OA would contract by the effect of its movement, so as to reestablish equality between the two double paths. … Read More
