Henri Bergson: Half-relativity – Michelson-Morley experiment (3)

|

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

Henri Bergson: Half-relativity – Michelson-Morley experiment (2)

|

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 moon in August 2023 will be a spectacular sight for skywatchers, as it will feature a rare blue moon, 2 full moons, 2 supermoons, and a partial lunar eclipse. A Blue Moon is a term used to describe a … Read More

Henri Bergson: Half-relativity – Michelson-Morley experiment (1)

|

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

The singularities as ontological limits of the general relativity

|

The singularities from the general relativity resulting by solving Einstein’s equations were and still are the subject of many scientific debates: Are there singularities in spacetime, or not? Big Bang was an initial singularity? If singularities exist, what is their … Read More

Henri Poincaré: Potential of an electric mass distributed on the surface of a sphere (2)

|

Suppose that we propose to find a function F which satisfies Laplace’s equation inside the sphere S and which, at the different points M of the surface of this sphere, take given values V°. The value of this function V … Read More

Henri Poincaré: Potential of an electric mass distributed on the surface of a sphere

|

Such is the present state of the question; let us see now what is the goal that I have in view; what would have been most interesting would have been to replace the current calculation methods with other less defective … Read More
