On the Establishment of a Universal Time
Published online by Cambridge University Press: 14 March 2022
Extract
The concept of simultaneity, and the associated problems of synchronization of moving clocks and establishment of a universal time scale, were given little or no attention prior to the twentieth century. In 1905, however, Einstein analyzed the concept of simultaneity on the basis of two principal postulates:
(1) Absolute velocity is meaningless (relativity postulate),
(2) The velocity of light in a vacuum is the same for all unaccelerated observers.
