#### Henri Bergson: Half-relativity – Michelson-Morley experiment (8) – Dislocation of simultaneity

What will happen when operators respectively placed at 0 and at A want to measure the speed of light by noting, on the clocks tuned together which are at these two points, the moment of departure, the moment of arrival, … Read More

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

But we should also know why we ourselves, in our turn, measuring the speed of light by terrestrial experiments such as those of Fizeau or Foucault, we always find the same number c, whatever the speed of the Earth relative … 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

Let us calculate, in fact, according to the usual kinematics, the duration of each of the double paths. In view of simplifying the exposition, we will admit that the direction SA of the luminous ray has been chosen so as … Read More

The theory of relativity, even “restricted”, is not precisely based on the Michelson-Morley experiment, since it expresses, in a general way, the need to preserve the laws of electromagnetism in an invariable form when passing from one system of reference … Read More
