The Equivalence Principle

Jaroslav J. Kopernicky
Year: 2012 Pages: 2
In formulating his General Theory of Relativity, Einstein described its fundamental postulate, the principle of equivalence, using as an example a physicist closed in a box (size not relevant). He insisted that a physicist inside could not tell the difference between gravity and acceleration. This writer analyzes this prediction and the equivalence principle by reviewing Einstein\'s original thought experiment.
