This section expands relativity to include gravity. Einstein describes gravity not as a force between objects, but as a curvature of spacetime caused by mass and energy. He uses the "Principle of Equivalence" to show that being in a gravitational field is indistinguishable from accelerating. Relativity: The Special and the General Theory,...

The book is divided into three main parts that build from the basics of motion to the grand structure of the cosmos:

The book includes appendices on the Lorentz transformation and experimental confirmations of his theory, such as the bending of starlight during a solar eclipse. Where to Access It Read the full text at the Project Gutenberg

Einstein's Relativity: The Special and the General Theory is one of the most significant works in scientific history, written specifically to explain his revolutionary ideas to the general public. Originally published in German in 1916, it remains a primary text for anyone looking to understand the universe through the eyes of its creator.

The text is famous for its "Gedankenexperimenten" (thought experiments), such as observers on moving trains and flashes of light, to make abstract concepts concrete. He uses the "Principle of Equivalence" to show

Einstein applies his theories to the entire universe, discussing its potential shape and whether it is finite or infinite. Key Features for Readers
