Source sentences:
text: Einstein explained this theory based on two postulates –
text: The theory dealing with gravity or) is based on the postulate that the local effects of a gravitational field and of acceleration of an inertial system are identical
text: The theory dealing with uniform motion (or) is based on the two postulates that physical laws have the same mathematical form when expressed in any inertial system, and the velocity of light is independent of the motion of its source and will have the same value when measured by observers moving with constant velocity with respect to each other.
text: The theory is based on two postulates: (1) that the mathematical forms of the laws of physics are invariant in all inertial systems; and (2) that the speed of light in a vacuum is constant and independent of the source or observer.
