From the theory of the special relativity to the theory of Lorentz
From big contribution of the classic mechanics, where Galileo's measurements served as base Newton for the securing of his laws of the movement, they gave to new position of the kinetic philosophy of this context saw with others eye, one handles that it was always operating on him the same force in his weight and the effect in the acceleration of constant form, since made that was demonstrating that the real effect of a force, was managing to change the magnitude of the speed of the body, instead of simply, another collision was in rectilinear movement where the body in this study was moving in a straight line with the same speed, we have another important law where one affirms that the body will hasten, or it will change sir speed, to a proportional rhythm by force. Nevertheless the absence of defining a standard in the absolute of rest, this one was meaning that it was not possible to determine if two events, of which in a simultaneous way they happened in different times, bearing in mind it had to have the same spatial position, but the position of Maxwell's equations, they were predicting that there could exist perturbations of undulatory character of the electromagnetic combined field and this which they would travel at constant speed, it was clear that the whole detail was converging in resolving more I submerge the problems showed in the spatial relativity, more when one adds the delay of the time and with her the contraction of a length, it was more opportune to explain the equivalence of all the system inerciales with regard to the set of the phenomena of the nature, it are where there brings in the theory of trasformación of Lorentz in space real of cuatros dimensions, it treats as a set of relations that they demonstrate of how there are related the measurements of a physical magnitude, obtained by two different observers, it is for it for which the transformations of Lorentz, they need the type of geometry of the space - time needed by the theory of Einstein.
A trasformación of homogeneous Lorentz is a linear trasformación, in this real space that supports the module of the vectors, as the elements of the trasformación they are real and therefore they are not them same of L, we will designate for Ʌ the trasformación real Lorentz. The condition of the vectors has equal module before and after the trasformación it is:

To the moment to speak about the fourth coordinated one it usually represented for x0 = ct, so that they spread the light in all the system isótropamente with clarity c, the square of the module of a vector must keep on coming given by the counterfoil.
Very interesting the Lorentz transformation, where it was a large base, for the use physical magnitude is a property in which they are measurable of a physical system, in which they can be assigned different values, since as a result of a measurement and That at the same time a relation of measures, using a pattern that has well defined that magnitude, on the other hand fellow readers we have, the hypothesis of the Ether as the carrier of light, was a hypothesis where it was assumed was the means for the propagation of Light, so it was used to explain the ability of light, under the scheme of the waves, to propagate through empty space, something that waves should not be able to do in a space vacuum. It provided the theoretical medium required by light wave theories.
Schematic representation of the wind of ether.
The distance between the mirrors and the semimirror has a length ' L ', that is to say, the ' Trip 1 ' (R1), it is equal to the ' Trip 2 ' (R2). A difference between the trips exists 1 and 2 observed ones in the Earth and out of the Earth where the trips for the external observer it is considered out of the planet, taking up office that this one is at rest.
Interferómetro of Michelson:
A - source of monochrome light
B - mirror semirreflectante
C - mirrors
D - it differs from way.
The key point of this experiment was with the intention of Michelson and Morley it was to measure the speed relative to the one that moves herself the Earth with regard to the ether, also it was experienced by clocks of luminous pulse by the end, of to form angles rectum between two equal clocks, trying in the possible biggest thing to create relative difference I bring in two clocks, with which it was possible to observe if there existed a decrease of his speed of an equal way, with the form of which this speed moves, in end the experiment was realized by a laser trying to demonstrate an analogy of the spatial relativity, I demonstrate that the frequency to which the laser was working, exercising a spectral line at atomic level under the neon content in this case, since the speed of the light is controlled by the same exercised frequency, and the mirrors of both ends of the laser. The frequency in the one that documented this phenomenon, was demonstrated it was the difference of the frequency pulsante partners with regard to that this money order with an angle of 90 grades, but actually it was not detected or registered it joins evidence of which a change of the frequency did not demonstrate pulsante, only observation the change of the magnetic field this where it was located.
Conclude with following reading partners, the important thing of everything it is like the theory of relativity, it caused other studies and theories in this field of the science just as the Lorentz, Maxwell's theory where this one had his approach on the waves of radio as the luminous ones should travel at a fixed certain speed, also Newton's theory under his scientific philosophy where he was affirming an absolute system of reference, since for it was supposed that the light was travelling at a certain fixed speed, where it was necessary to determine what system of reference, it be necessary to use to be able to measure oneself this speed, after so many current arises from the ether which is in the gap of the space, that in turn this one is also they were using the wave study, in the light must travel to just as the sound, using the way of the air is for it for which it is relative proper of ether, where this one was showing that according to as his hypothesis was postulated, in which they would see bringing the light over with different speeds, but the speed of the light with regard to the ether would remain fixed and his individual, staying that the Earth was moving across the ether in his orbit about the Sun, it is a question of spreading in a creative and educational way to explain contents as this one in the field of the science.
