Posted by MacDood

This is the second of a series of elementary, informal, and mostly equation-free articles descibing the Theory of Relativity in physics. The series will have four installments: Part I: History This described the history of ideas in the development of relativity. Part II: Special Relativity This describes Einstein's Special Theory of Relativity. It assumes a familiarity with Part I but assumes very little in the way of prior understanding of physics. Part III: General Relativity This will give at least a taste of Einstein's General Theory of Relativity, which extends the Special Theory to cases involving acceleration and gravity. Part IV: Implications, Controversies, and Miscellany This will address implications of the Theory of Relativity, controversies both old and modern, and anything else that isn't covered in the first three installments.
