In his long-awaited new book, physicist and popular science writer Barry Parker speaks to the broadest possible audience in bringing Einstein's theories to life. Given the fervent renewed appreciation for the contributions Albert Einstein has bestowed on humanity, Parker thinks it only right to dedicate a book to explaining in the clearest possible terms the meaning and beauty of Einstein's theories.While tracing the story of Einstein's life, Parker seizes on the crucial groundbreaking theories that Einstein envisioned. Not since Isaac Newton had anyone conceived the universe in such a revolutionary, startling new way. Through Parker's eloquence, eye for detail, and clever use of Einsteinian cartoons and vivid illustrations, he enables the reader to see and appreciate for perhaps the first time the full meaning and scope of Einstein's Special Theory of Relativity and General Theory of Relativity.Parker then guides the reader to the next step in Einstein's revelations: the possibility of time travel. In exploring the fascinating implications of Einstein's thought, Parker treats us to the experience of discovering a black hole, traversing curved spacetime, and greeting our much younger twin who has just returned from a long and arduous spaceflight.Parker's incomparable gift for language captures Einstein's uniqueness, singular brilliance, and stunning theories. The clarity of the writing coupled with the many illustrations will drive home the point why so many consider Einstein to be the greatest scientist who ever lived and Time magazine named Albert Einstein "Person of the Century."
