I just wanted to emphasize that a clock works autonomously. Regardless of whether it is watched or not, a clock goes uniformly. Einstein later tried to prove his „twin“ theorem with the general relativity...

Well, from that the time dilation can be deduced. Otherwise I see no contradiction to my consideration.

To determine the simultaneity at different locations, the running time of the light must be considered... I do not have against the twin paradox - the calculation is correct. But ... it's about natural processes. Physically, no clock can exist that displays more time than it counts with "ticks"...

You presented one of the possible calculation for the twin paradox. But that is not the point. Einstein assumes the existence of such a clock, which indicates more time than would have passed according to its speed. In nature there is no such clock. Therefore his assumptions should be...

We can mark all clocks. The moving observer will then enter in a table which clock which time has indicated (compared with his own time). When the moving observer sees the first clock again, he can check his table. He will notice that this clock shows too much time, although it is just as slow...

It should not be forgotten that Einstein formulated his theorem in the context of the special theory of relativity. He begins with a polygonal route: "...It is at once apparent that this result still holds good if the clock moves from A to B in any polygonal line..." and only after passes to...

What does "naive" mean? It is a basis of the theory of relativity: the principle of relativity! Every observer can consider himself at rest. Therefore he uses the Lorentz transformations. In this way every observer gets the same result. This also affects time dilation. By the way, the movement...

Exactly! One of the twins has to admit that his system is so to say subordinate. Then, why should not he believe his eyes, if he sees that the clock in point A is slower than his own clock?

So, the moving observer always watches the clock at point A. If he moves away from point A, in his view the clock at point A goes slower. If he moves to point A, the clock at point A goes faster. If he reaches point A, the clock will go renewed slower than his own clock. Here I miss the actual...

Hello! Einstein's theorem is in the last sentence of the following quote (bold) [1]: "If at the points A and B of K there are stationary clocks which, viewed in the stationary system, are synchronous; and if the clock at A is moved with the velocity v along the line AB to B, then on its...

Just during the event time in Hanford was undergoing the maintenance work on the mirrors. This resulted in the minute-long stripe 19-23 Hz in the data records (figure below, left) The authors are sure that there is no connection to the gravitational wave signal. The right diagram is to prove...

These measurements were made ​​for very large distances from the sun. For example, observation angle of Hipparcos varied between 47° and 133°. But the solar radius is 16' = 0.27°. The observation angle of 47° correspond to roughly 47° / 0.27° = 176 solar radii. 1985 Schmeidler systematized the...

In the essay „Über die Ablenkung des Lichtes I am Schwere*feld der Sonne“ ( http://adsabs.harvard.edu/full/1931ZA...3..171F ) the authors - Freundlich, Klüber and Brunn - presented 1931 graphically the results of three expeditions, which took place 1919, 1922 and 1929. They put together all...

I have also not only books: http://www.cobalt.chem.ucalgary.ca/ziegler/educmat/chm386/rudiment/tourexp/photelec.htm http://www.cobalt.chem.ucalgary.ca/ziegler/educmat/chm386/rudiment/tourexp/photef1.gif "This graph shows the typical results of an experiment." Simulation does not meet this...

In the simulation are available only simple metals, i.e. no bialkali photocathode. In addition, QE is not the same as photo current. QE = i/i_max = n*e/i_max i_max = n_max*e, n_max = I/hv => QE = n/(I/hv), n is the number of emitted electron
