The ten biggest ideas in theoretical physics that have withstood the test of time Could any discovery be more unexpected and shocking than the realisation that the reality we were born into is but an approximation of an underlying quantum world that is barely within our grasp? This is just one of the foundational pillars of theoretical physics that A. Zee discusses in this book. Join him as he presents his Top Ten List of the biggest, most breathtaking ideas in physics the ones that have fundamentally transformed our understanding of the universe. Top Ten Ideas of Physics tells a story that will keep readers enthralled, along the way explaining the meaning of each idea and how it came about. Leading the list are the notions that the physical world is comprehensible and that the laws of physics are the same here, there, and everywhere. As the story unfolds, the apparently solid world dissolves into an intertwining web of dancing fields, exhibiting greater symmetries as we examine them at deeper and deeper levels. Readers come to see how physical truth is universal, not relative, and how the forces in the multiverse are not disparate pieces but an indivisible unity a vision only partially realised today. With Zee's trademark blend of wit and physical insight, Top Ten Ideas of Physics reveals why the book of nature is written in the language of mathematics, why entropy and information are intimately linked, and why the action principle underpins the choreography of all that exists.
