Special Relativity, Equivalence Principle, and Mach's Principle - Lecture 4

Delve into the intricacies of special relativity, the equivalence principle, and Mach's principle in this graduate-level lecture from the Warsaw4PhD and GeoPlanet PhD schools. Explore electromagnetism in special relativity, examining fluxes and densities before diving into the stress-energy tensor. Gain a deeper understanding of the equivalence principle and its implications for general relativity. Conclude by investigating Mach's principle and its role in the development of Einstein's theories. Presented by Mikołaj Korzyński from the Center for Theoretical Physics, Polish Academy of Sciences, this comprehensive lecture offers advanced insights into fundamental concepts of theoretical physics over the course of 1 hour and 38 minutes.
