Nobel Laureate Albert Einstein was one of the world's most brilliant minds. Arguably the founder of modern physics, his scientific ideas and research changed the world. His book Relativity: The Special and the General Theory is regarded as a seminal work-one of the most important and influential scientific ideas to have emerged out of the 20th century. First published in 1916, the book explores the relationship between space, time, and the theory of gravitation-offering a new perspective on the universe. Einstein, using minimum mathematical terms and equations, explains some of the basic ideas and principles behind our world and the forces that have shaped it. The General Theory speaks of black holes, the evolution of the Universe, the behaviour of orbiting neutron stars, why clocks run slower on Earth than in space, and even suggests the possibility of time travel. Ingenious and insightful, Relativity is a must-read for anyone who wants to expand their mind and learn about the universe and its working.
