Physics: Fighting for time, Nature 521, 286-287 (21 May 2015): "...tensions between Einstein and French philosopher Henri Bergson. Their quarrel about the nature of time is the subject of The Scientist and the Philosopher, a hefty, stimulating study by science historian Jimena Canales. (...) Canales aims to clarify the essence of the quarrel without taking sides. Reading between the lines, she seems to sympathize with maverick twentieth-century physicist and critic of relativity theory Herbert Dingle, who lamented that in general the scientist "understands what he is doing about as well as a centipede understands how he walks"."

SCIENCE AT THE CROSSROADS, Herbert Dingle, p.27: "According to the special relativity theory, as expounded by Einstein in his original paper, two similar, regularly-running clocks, A and B, in uniform relative motion, must work at different rates. (...) How is the slower-working clock distinguished?"
Dingle's question is rhetorical - the slower-working clock cannot be distinguished on the basis of Einstein's 1905 postulates alone. The postulates entail that, as judged from the respective system, either clock runs slower than the other. That is, for an observer in the moving clock's system, the stationary clock lags behind the moving clock; for a stationary observer, the moving clock lags behind the stationary clock. Neither clock is privileged. Yet in 1905 Einstein didn't understand that:

ON THE ECTRODYNAMICS OF MOVING BODIES, A. Einstein, 1905: "From this there ensues the following peculiar consequence. 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 tv^2/2c^2 (up to magnitudes of fourth and higher order), t being the time occupied in the journey from A to B."
So Einstein's famous conclusions that made him a superstar, "moving clocks run slow" and "travel into the future is possible", are based on two flaws. Initially Einstein advanced his false constant-speed-of-light postulate, which allowed him to validly deduce that:
moving clocks run slow, as judged from the stationary system.
Then he illegitimately dropped the second part of the above conclusion and informed the gullible world that:
moving clocks run slow, that is, travel into the future is possible.

Michio Kaku, Brian Cox, Neil deGrasse Tyson, Brian Greene, Lisa Randall: "Light travels at the same speed no matter how you look at it. No matter how I move relative to you light travels at the same speed. No matter who is doing the measurement and no matter what direction you are moving the speed of light is the same. The speed of light is the same no matter what direction or how fast... As you travel faster time slows down. Everything slows down. Everything slows down. Time slows down when you move. Time passes at a different rate. Clocks run slow. It's a monumental shift in how we see the world. It's a beautiful piece of science. It's a beautifully elegant theory. It's a beautiful piece of science. It's a beautiful piece..."
