Coordinate

Try to calculate in more detail. What is the differential – is the limit of finite differences. We write the finite difference (eg, x): x1 = (vt'1 + x'1) / (1-v / c ) (4A) This is correct. We write x2. From a mathematical point of view – have changed the codes and everything. But from a practical point of view to measure x2 (to keep the synchronization clock to all the coordinates correspond to each other) can only signal that goes from S 'in S. This signal goes from x2 ', is the center coordinates of S', then goes to the center coordinates of S.

Interested parties can try to measure yourself. All literature on this dimension, describes just such a way. However, measuring this way corresponds to the minus sign in the velocity (in absolute values) in the formula (1A). Read more here: Lynn Redgrave. This means that the finite difference we do not record. Velocity addition formula is easily obtained from a comparison of size, such as line length L, in different inertial coordinate systems. Take the three inertial coordinate system S, S ', S'': S – rest, S'-moving S with velocity v, and S''- moving in S 'with velocity u'. Then the lengths respectively are L, L ', L''. If the initial time points of coordinates coincide (top line coincides with the center coordinates), then the coordinate of the end line coincides with its length. Coordinates of different coordinate systems (and consequently the end of the line) we do not associate with each other.

And it is because we have the scores in our mind, rather we know the frequencies of the past, this is our starting point to know that note is that follows the one we know at present. I could say that our goal is to find the last note of the universe, in order fully understand and contemplate the beautiful harmony in its entirety. And whether that last note is God or the Big Crunch, we must recognize that we do not know where we shout. Then we enter the realm of science fiction, and that sometimes we can anticipate a note, but is sometimes wrong instrument. The science fiction, which was called the literature of anticipation, is undoubtedly a map that helps science to find the different possible paths to our intellectual advancement, technological and even social (part of their subdivision "soft" for the latter .) And so the story reveals. No one knows the exact time concisely its emergence, there are even researchers who disclose the hypothesis that the origin of science fiction dates from ancient Greece, and others, which give more reliability, which postulate early birth nineteenth century. Anyway first became popular in the mid-twentieth century, and was in this and the previous century where guys like HG Wells, Jules Verne, Isaac Asimov, and many scientists, writers developed this literary genre, of which a large part of them was a scientist, and here I stand with the question "has something to do actual science (with its new properties of firmness and the requirement of strict experimental verification) with the tendency of some scientists to become science fiction writers?. .
