آينشتاين

Einstein's theories were huge leaps in the field of science, but he still thought in the language of simple physical images: train acceleration, elevator descents, rockets, the movement of clock hands, and in fact, the theory of relativity — which was a groundbreaking event that shook the world — came as a result of two simple images of this kind. The first image occupied Einstein's mind since he was sixteen years old, when he tried to imagine what light rays would look like if he could move alongside them at the same speed. His exploration of the nature of the rest of light waves led him to relativity and to the famous equation that energy equals mass times the square of the speed of light, the equation that solved the mystery of the stars. The second image came to Einstein while sitting in his chair at the Bern patent office, when he asked himself what if he fell? This seemingly humorous image led him to the idea that the fabric of space and time is curved, replacing Newton's mysterious "force" of gravity. This idea in turn led to his theories of black holes and the Big Bang. Einstein remains one of the greatest scientists and closest to hearts in all ages, but many of us are unable to understand his work and legacy correctly. This book is a wonderful way to understand Einstein's life and ideas and to truly appreciate them, thanks to Michio Kaku's intelligence and his ability to explain the most complex scientific concepts in everyday language we use in our daily lives.
