Transfer of Clock Reading in A Twin Paradox Trip
An "out and back" twin paradox adventure may incorporate the transfer of clock reading from an "outgoing" astronaut to an "incoming" astronaut, thus entirely eliminating the effect of acceleration. Acceleration is not involved in any kinematical effects of special relativity. The time differential between two reunited clocks is deduced through purely uniform linear motion considerations, as seen in Einstein's original paper on the subject, as well as in all subsequent derivations of the Lorentz transformations.
Because spacetime diagrams incorporate Einstein's clock synchronization, there will be a requisite "jump in time" in the calculation made by a "suddenly returning astronaut" who inherits a "new meaning of simultaneity" in keeping with that clock synchronization (with its lattice of clocks methodology) as explained in Spacetime Physics by John A. Wheeler. Such clock synchronization makes an absolute frame of reference superfluous for all predictive purposes.
If, instead of incorporating Einstein's clock synchronization (lattice of clocks), the astronaut (outgoing and incoming) and the Earth-based party regularly update each other on the status of their clocks by way of sending radio signals (which travel at light speed), then all parties will note an incremental build up of asymmetry in time-keeping, beginning at the "turn around" point. Prior to the "turn around", each party regards the other party's clock to be recording time differently than his own, but the noted difference is symmetrical between the two parties. After the "turn around", the noted differences are not symmetrical, and the asymmetry grows incrementally until the two parties are reunited. Upon finally reuniting, this asymmetry can be seen in the actual difference showing on the two reunited clocks.

Famous quotes containing the words transfer, clock, reading, twin, paradox and/or trip:
“If it had not been for storytelling, the black family would not have survived. It was the responsibility of the Uncle Remus types to transfer philosophies, attitudes, values, and advice, by way of storytelling using creatures in the woods as symbols.”
—Jackie Torrence (b. 1944)
“Stands the Church clock at ten to three?
And is there honey still for tea?”
—Rupert Brooke (1887–1915)
“A baby is a full time job for three adults. Nobody tells you that when you’re pregnant, or you’d probably jump off a bridge. Nobody tells you how all-consuming it is to be a mother—how reading goes out the window and thinking too.”
—Erica Jong (20th century)
“We live under continual threat of two equally fearful, but seemingly opposed, destinies: unremitting banality and inconceivable terror. It is fantasy, served out in large rations by the popular arts, which allows most people to cope with these twin specters.”
—Susan Sontag (b. 1933)
“The paradox of education is precisely this—that as one begins to become conscious one begins to examine the society in which he is being educated.”
—James Baldwin (1924–1987)
“The Statue of Liberty is meant to be shorthand for a country so unlike its parts that a trip from California to Indiana should require a passport.”
—Anna Quindlen (b. 1952)
