International BestsellerThe Special and the General TheoryAlbert Einstein–the father of modern physics proposed the theory of relativity. Even today, scientists find evidence supporting his theories while conducting research with advanced equipment. He wrote this book “to give an exact insight into the theory of relativity to those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics. â€While the theory of relativity enriched astronomy and physics during the 20th century, technology today is getting ahead because of Einstein. Relativity: The Special and the General Theory caters to those interested in understanding the conceptual basics of scientific and technological advancements that Einstein proposed, in simple terms. Albert Einstein (1879–1955) was one of the greatest scientists of the 20th century. Born in Germany, Einstein worked as a clerk before stepping into the world of technology. He became an American citizen in 1940 and taught at Princeton University. His work on the photoelectric effect won the Nobel Prize for Physics in 1921, and later became the basis of tremendous developments in quantum theory and electronic technologies and the atomic age.
