Principles of Relativity: Overview of Special Relativity – spacetime interval and Lorentz metric – four vectors – Introduction to general relativity (GR) – equivalence principle – notions of curvature – gravitation as a manifestation of the curvature of spacetime – gravitational redshift and clock corrections – orbits in strong gravity, light bending and gravitational lensing – concept of horizon and ergosphere, hydrostatic equilibrium in GR – gravitational radiation.
