The Jocaxiano TrainBy Jocax November / 2016===================Abstract: This article shows two very simple and analogous situations in relation to the classic mental experiment(Known as the 'Einstein Train') that explains the temporal dilation and then points out a contradiction between them.The Einstein Train It is familiar to every student of theory of relativity restricted to the mental experience that showsThe temporal dilatation occurring when the invariance of the measurement of the speed of light is postulated.Here are some examples of site links:Einstein's train and the dilation of time:http://acervo.novaescola.org.br/ciencias/fundamentos/einstein-teoria-relatividade-dilatacao-do-tempo-605460.shtml2- http://www.infoescola.com/fisica/dilatacao-do-tempo/3-http: //alunosonline.uol.com.br/fisica/dilatacao-do-tempo.htmlWe can see, in these classic examples, that the observer who sees the beam of light go back and forth along the same path in its frame,(In these examples the observer that is inside the wagon where also the source of light is)Calculates a shorter time for the path of light than the observer who observes the light making a longer path,As part of a "triangle" (in this case, the observer at the station).Therefore, the observer's clock in the carriage moves more slowly relative to the observer than the one in the station(Which measures a longer time for the light path), so that for both, the speed of light is the same (= c).This phenomenon is known as "temporal dilatation."(In short, it suffers from temporal dilatation that observes the light to make the smallest path, in this case, who is inside the train in movement).All very didactic and simple. Behold, then comes the Jocaxian Train.The Jocaxiano TrainThe Jocaxiano train is nothing more than the old train of Einstein with a beautiful hole in the ground! (i.e.As the train passes, a lantern, halted on the ground of the station, emits a beam of light through the hole and enters the moving train hits the mirrored ceiling of the trainAnd back to the same flashlight that emitted the beam (if the hole is large enough).That is, when the Jocaxiano train passes, the light enters through the hole hits the ceiling and returns to the lantern making a similar go and returnTo Einstein's Train but, whoever is in the station now is watching the light go back and forth along the same path (the shortest way!). Already for the observer who is in the moving car the light makes a longer course, as a part of "triangle".That is, whoever is in the moving car observes a greater path of the beam of light than the observer stopped at the station.Therefore, since the two observers must measure the same speed for the light, the time, within this Jocaxian Train,Passes faster than to the observer who is standing at the station and sees the light making the smallest way.Thus, in this case, time dilation suffers who is off the train at rest, ie the time passes faster to the observerOn the train in motion: the one who watches the light makes a longer journey. ParadoxSo this mental experiment shows that we have a paradox in restricted relativity, the same physical train,The same observers, suffer a temporal dilation that depends on where the light comes from, whether inside or outside
