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

Isaac Newton on the action at a distance in gravity: With or without God?

|

The interpretation of Isaac Newton’s texts has sparked controversy to this day. One of the most heated debates relates to the action between two bodies distant from each other (the gravitational attraction), and to what extent Newton involved God in … Read More

Causal Loops in Time Travel

|

About the possibility of time traveling based on several specialized works, including those of Nicholas J. J. Smith (“Time Travel“), William Grey (”Troubles with Time Travel”), Ulrich Meyer (”Explaining causal loops”), Simon Keller and Michael Nelson (”Presentists should believe in … Read More

Physics Help

The book is an overview of the major subfields and concepts in physics, including a brief outline of the history of physics and its subfields. Physics (from Greek from φυσικός (phusikos): natural, from φύσις (fysis): Nature) is the science of … Read More

Henri Bergson: Half-relativity – Michelson-Morley experiment (7) – Clock simultaneity

|

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

Henri Bergson: Half-relativity – Michelson-Morley experiment (6) – Measuring time

|

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

Henri Bergson: Half-relativity – Michelson-Morley experiment (5) – The speed of light

|

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

Presocratics – Milesian physics (1)

|

In the first period, the Hellenic period which ended with the death of Alexander (323 BC), philosophy developed in Greek countries and successively in various centers: this succession corresponds to political vicissitudes. It was born in the 6th century in … 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
