”There is, however, one case where I will have to take your indications into account and modify my measurements. It is when it is a question of constructing an integral mathematical representation of the universe, I mean of everything that … Read More
Now I must add that I consider these changes beneficial. Let us indeed leave ponderable matter behind. What would my situation be with regard to light, and more generally electromagnetic facts, if my dimensions of space and time had remained … Read More
We have just looked for how light could have the same speed for the fixed observer and for the moving observer: the deepening of this point revealed to us that a system S’, resulting from the splitting of a system … 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
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
(Art drawing about the theory of relativity) The theory of relativity includes both the theory of special relativity as that of general relativity formulated by Albert Einstein in the early twentieth century, who sought to resolve the incompatibility between Newtonian mechanics and electromagnetism. The theory of special relativity, published in 1905, deals with the physics of … Read More
Are we really sad during the yellow autumn, or she is dreary? Nicolae Sfetcu, 06.10.2017
