An Educational Review on Einstein's Special and General Relativity for Undergraduate Physics Students

This preprint presents a structured educational review of Einstein’s theories of special and general relativity, aimed at undergraduate physics students. The article discusses foundational concepts such as Lorentz transformations, time dilation, Minkowski spacetime, and Einstein’s field equations. It emphasizes conceptual clarity and mathematical structure, bridging classical mechanics and relativistic physics. This work is a refined and summarized version of an academic term project and is intended to support learning and scientific outreach.
