Relativity: The Special and General Theory by Albert Einstein: A Complete Summary "The eternal mystery of the world is its comprehensibility." Overview Relativity: The Special and General Theory (1916) is Albert Einstein's own attempt to explain his revolutionary theories to the educated general reader. It is a rare document: one of the most important scientists in human history explaining, in his own words and with deliberate simplicity, the ideas that overturned our understanding of space, time, matter, and energy. Einstein's theories of relativity did not merely refine Newtonian physics; they replaced it with a fundamentally different picture of the universe. Space and time are not absolute and unchanging but relative and intertwined. Mass curves the fabric of space-time. The speed of light is the same for all observers, regardless of their motion. And energy and mass are interchangeable, related by the most famous equation in science: E=mc2. The book is divided into three parts. The first explains special relativity, which deals with objects moving at constant speeds. The second explains general relativity, which extends the theory to include gravity and acceleration. The third discusses cosmological implications. Einstein writes with clarity and intellectual humility, frequently acknowledging where the ideas are difficult...
