Equivalence Principle Introduced (Lecture #07a of a course on Relativity & Cosmology)
Показать описание
Part 2 Equivalence Principle (Book Ch 4, and video lectures #07 to #09 )
Course textbook: A College Course on Relativity and Cosmology by Ta-Pei Cheng
Description: Historically, Einstein used the idea of the equivalence between gravitation and inertia to proceed from special to general relativity. Some GR results can be obtained in this physically more accessible approach.
Learning objective: Understanding how Einstein used the Equivalence Principle (EP) to extract some GR results (gravitational redshift, time dilation, and light deflection) and in turn how such physics led him to the idea that gravitational field is simply a curved spacetime.
