"Relativity: The Special and General Theory" by Albert Einstein is a popular science book published in German in 1916. Written for readers without advanced mathematical training, it explains Einstein's revolutionary theories of special and general relativity in accessible terms. Through thought experiments involving trains, light, and moving observers, Einstein reveals how time, space, and simultaneity are relative concepts rather than absolute truths. The book demonstrates how these insights unite fundamental laws of physics in unexpected ways. (This is an automatically generated summary.)
