It is my understanding that the twin paradox arose from the fully reciprocal nature of special theory which shows that if a clock is moving past me in outer space that clock is ticking over at a slower rate than my clock but that from the point of view of a person accompanying that clock it is my clock that is ticking over at a slower rate than his clock; the paradox, apparently, being that both clocks cannot be ticking over at a slower rate than the other one (the original ‘clock’ paradox). In his 1918 Naturwissenschaften article Einstein attempted to negate this paradox insisting that it is only the clock that has been made to move to the other clock’s location that incurs time dilation on the basis that it experiences forces of acceleration however in chapter 4 of his 1905 article ‘On the Electrodynamics of Moving Bodies’ Einstein wrote:- “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 arrival at B the two clocks no longer synchronize, but the clock moved from A to B lags behind the other which has remained at B by ·5tv2/c2.....” My reason for posting this message is that, having been made to move from A to B clock A (although Einstein does not refer to this fact) must have accelerated. The alternative is that clock A incurred instantaneous velocity which, I assume, is a concept that Einstein would not have tolerated ergo his chapter 4 depiction effectively provides a similar explanation for the eventual discrepancy between clocks A and B as did his 1918 article. On the basis that Einstein’s chapter 4 STR clock A accelerated, moved toward B at v then decelerated this is analogous to an astronaut’s return journey following turn-around. As a result of his outward-bound journey the astronaut’s clock will lag behind his twin’s clock by ·5tv2/c2.. As a result of his inward-bound trip the astronaut’s clock will lag behind the twin’s clock by an additional ·5tv2/c2. I have read several interpretations of the twin paradox one of which insists that the traveler’s clock does not (as Einstein expressed it in chapter 4) ‘go more slowly’ than the Earth clock but that the Earth clock, from the traveler’s point of view, ticks over at a faster rate than his own clock but only during the astronaut’s period of acceleration following turn-around however it is my understanding that the concept of time contraction was, for Einstein, an anathema. Although I have included Einstein’s chapter 4 equation it would very much be appreciated if responses did not incorporate mathematical ‘proofs’ or explanations. I am, as was Faraday, one of those annoying self-taught persons who has no comprehension of mathematics and, like Faraday, prefers simple, every-day language interpretations. Einstein insisted that as far as the propositions of mathematics are certain, they do not refer to reality and I tend to agree.
