Course Description

Overview

Explore Einstein's General Theory of Relativity in this comprehensive 2-hour 23-minute lecture by G Srinivasan from the International Centre for Theoretical Sciences. Delve into the physical content of the theory, tracing its development from Newton's laws to Einstein's groundbreaking ideas. Examine key concepts such as the principle of equivalence, gravitational redshift, and light deflection. Learn about the Einstein-Grossmann collaboration, Einstein's field equations, and the Schwarzschild solution. Gain insights into the historical context, including Einstein's "happiest thought" and the 1919 solar eclipse observations. Understand how Einstein's work revolutionized our understanding of gravity, spacetime, and the universe.
