Editing Mach's principle (section)

== Inertial induction ==
In 1953, in order to express Mach's Principle in quantitative terms, the [[University of Cambridge|Cambridge University]] physicist [[Dennis W. Sciama]] proposed the addition of an acceleration dependent term to the [[Newton's law of universal gravitation|Newtonian gravitation]] equation.<ref>{{Cite journal|last=Sciama|first=D.

Sciama referred to the effect of the acceleration dependent term as [[Inertial Induction]].
