BTW, you made a mistake on your formula. v and w need to be squared, and whole (1 - v^2/w^2) needs to be square-rooted (http:// en.wikipedia.org/wiki/Time_dilation, note the formula). I won't make a big deal out of the fact that you used an ... unconventional letter for speed of light. It's usually c. As far as mathematics goes, special relativity has nothing special about it---if you accept Einstein's two postulates, in particular, the one that says that speed of light is the same in all inertial frames (so c does not change between x and x'), the rest is high school algebra, at least up to the formula for time-dilation (assuming you found the Lorentz transformation which satisfies the postulate about c). What you would instead need to do is show experimentally (which is not proof, although if thoroughly checked enough, it could be considered a counter-example) that this relationship does not hold, which would imply that Einstein's postulate, as simple as it was, was not correct. And I believe some guys did take an atomic clock around the world on an airplane, and the deviation of the clock on the plane (compared to the one left on ground) matched the theoretical prediction, within the experimental error). So, unless you just want to repeat the same old experiments, you probably should wait until we can build starships (or at least a probe which can travel far at some high velocity and carry enough fuel to reverse its direction and come back to us).

This whole thing started as an obscure millenarian cult among the Jews, and very few of them held citizenship.

These are not the Lorentz equations. They are equations derived from the Galilean transformation equations, the equations scientists discarded when Einstein began using the Lorentz equation to describe transmission of light. Velocity of light is w, not c, because the velocity of a photon traveling on the x axis of a set of Cartesian coordinates in the negative direction is -c, not c. The Lorentz equations ignore this fact by leaving the equations in an unreduced form so that c is always squared in those equations. (-c)(-c)=c^2 Scientists do not like these equations because they cannot disprove them, and they give answers almost identical to Lorentz equation answers with regard to anything that can be measured directly, such as the orbit of Mercury, which was the first proof used to show that the times given by the Lorentz equations agreed with scientific measurements better than Newton's equations for gravitation.
