"The influence of Einstein's contributions on so many branches of physics is such that if one wanted to describe its full extent, it would be hard to know where to begin. His work and discoveries...are so fundamental that each achievement alone would have guaranteed him a prominent place in the history of physics. But what brought him unprecedented fame outside his own discipline is undoubtedly his theory of relativity, which revolutionized the old, established Newtonian picture of space, time, and gravitation."Professor Hanoch Gutfreund, from the Introduction This volume, an abridged version of our cloth, slipcased edition, presents one of the most influential scientific documents of the twentieth century: Albert Einstein's exposition of the theory of relativity. Each of the seventy-two handwritten pages are reproduced and are accompanied by an English translation of the original German text. A tribute to Einstein's genius, Einstein's 1912 Manuscript on the Special Theory of Relativity opens with a brief essay by Hanoch Gutfreund, a chronology of Einstein's life, a selection of quotes by Einstein, and, to introduce the manuscript, a detailed description of the manuscript, its contents, publication history, and provenance. The manuscript pages themselves then follow, reproduced in full color, with the English translation facing each page. Subtle variations in paper and ink are clearly visible in the excellent reproductions, indicating where and when Einstein drafted certain parts. Because the manuscript shows extensive reworking, it reveals Einstein's thought processes more than any other of his handwritten works. Providing a glimpse into one of the greatest minds of the last century, Einstein's 1912 Manuscript is for anyone fascinated by Einstein and the impact of his revolutionary theory. 72 color pages.

Me: “I think of the two postulates, the relativistic increase in the (effective) mass is valid and is an experimentally observed fact, for example when you accelerate the subatomic charged particles like electrons, protons etc. in accelerators. From a materialist point of view, the electromagnetic radiation (photons) or energy must be some form of matter and hence must be at unity with the ordinary form of matter. On a hindsight, this intuition was possible even before Einstein gave his mathematical relation of the equivalence of mass and energy.. Even our everyday experience shows that higher velocity imparts more momentum (mxv) and hence more kinetic energy (1/2mxv^2) to a body.
Most theories of “New Physics” and their supposed implications are based on idealization, e.g., i) the unlimited extension of the theories (and laws) of old physics, beyond their natural limits; like the concept of entropy as is now used in the subatomic and the cosmic sense, ii) speculations based on idealized mathematics and the concept of “fields” (not matter particles) as the ultimate basis of reality; homogenous “fields” by the way are suitable for idealized mathematics, iii) positivist thought experiments of how one would “feel” rather than doing a realistic experiment to verify that “feeling”; iv) a finite universe, because mathematics cannot deal with infinity.
You are right in asserting that, “This are only some thoughts regarding the fraction 1/sqrt(1 - v^2/c^2) and it is difficult to say it describes something existing in the real nature.” The theory of special relativity (SR) describes mechanics at very high speed, which is far beyond real ordinary experience. But the conclusion of SR that you cannot “accelerate” material body from low speed to close to or beyond the speed of light is well established. But it does not mean that radiation or energy quanta cannot have “intrinsic velocity” beyond that of light photons. In fact it was shown in some experiments in Germany (can’t recall the ref.) that all the photons in a wave-front did not have the same exact value but a small but measurable scattering (a Gaussian distribution) of some more than c and some less.
Gravitons, if they exist must have much-faster-than-light velocity to make a gravitational effect at the enormous distances between galaxies for example. We almost came very close to finding faster than light neutrinos recently, but only a “loose connection” in some cable was the spoiler. Monopoly capitalism has tricks up its sleeve to “prove” and to safeguard its Invariable and Absolute “truths” that conform to its worldview and theological notions; only the quantum phenomena and the “theory of evolution” somehow became exceptions, but still not fully accepted.” ( )
