Quantum field theory is by far the most spectacularly successful theory in physics, but also one of the most mystifying. Quantum Field Theory, as Simply as Possible provides an essential primer on the subject, giving readers the conceptual foundations they need to wrap their heads around one of the most important yet baffling subjects in physics.

Fearful Symmetry brings the incredible discoveries of contemporary physics within everyone's grasp. A. Zee, a distinguished physicist and skillful expositor, tells the exciting story of how today's theoretical physicists are following Einstein in their search for the beauty and simplicity of Nature. Animated by a sense of reverence and whimsy, the book describes the majestic sweep and accomplishments of twentieth-century physics. In the end, we stand in awe before the grand vision of modern physics--one of the greatest chapters in the intellectual history of humankind.

"A quantum field theory text for the twenty-first century, this book makes the essential tool of modern theoretical physics available to any student who has completed a course on quantum mechanics and is eager to go on." "Without a solid understanding of quantum field theory, no student can claim to have mastered contemporary theoretical physics. Offering a remarkably accessible conceptual introduction, this text will be widely welcomed and used."--Jacket.

On Albert Einstein's seventy-sixth and final birthday, a friend gave him a simple toy made from a broomstick, a brass ball attached to a length of string, and a weak spring. Einstein was delighted: the toy worked on a principle he had conceived fifty years earlier when he was working on his revolutionary theory of gravity--a principle whose implications are still confounding physicists today. Starting with this winning anecdote, Anthony Zee begins his animated discussion of phenomena ranging from the emergence of galaxies to the curvature of space-time, evidence for the existence of gravity waves, and the shape of the universe in the first nanoseconds of creation and today. Making complex ideas accessible without oversimplifying, Zee leads the reader through the implications of Einstein's theory and its influence on modern physics. His playful and lucid style conveys the excitement of some of the latest developments in physics, and his new Afterword brings things even further up-to-date.

This modern textbook on group theory is tailored for physicists, addressing a crucial mathematical subject that underpins various fields of theoretical physics, including atomic, condensed matter, particle physics, and string theory. It is particularly vital for understanding fundamental forces. The book fills a gap by offering a user-friendly and classroom-tested resource that emphasizes the aspects of group theory most relevant to physicists. A. Zee guides readers from the basic concept of a group to advanced topics, such as theories based on gauge groups that could unify three of the four fundamental forces. Additionally, it includes a concise review of the necessary linear algebra, making it suitable for self-study. The text covers applications across multiple areas of physics, including field theory, particle physics, and relativity. Key topics addressed are finite groups and character tables, various representations, the Weyl, Dirac, and Majorana equations, and the relationship between group theory and the expanding universe, among others. This essential resource serves as a textbook for students and a valuable reference for researchers. It features a brief, self-contained treatment of linear algebra, and an online illustration package is available for professors, along with a solutions manual exclusive to educators.

Gravitace je jednou ze čtyř základních fyzikálních sil; je nejnápadnější - ani naprostý laik nepřehlédne, že věci padají k zemi - a paradoxně zároveň nejslabší (gravitace celé zeměkoule nedokáže strhnout maličký magnet z ledničky). Autor vykládá vztah gravitace a ostatních sil, rekapituluje, jak byla gravitace vnímána a vykládána, a zastavuje se zejména u Newtonova gravitačního zákona, který po tři století postačil k popisu gravitačního působení v okolí zeměkoule. Pak ovšem přišel Albert Einstein a svou obecnou teorií relativity popsal gravitaci obecněji, a vzal v úvahu i jevy, o kterých nemohl mít Newton ani tušení - nepředstavitelné rozměry vesmíru a těles, která v něm existují, působení gravitace na světlo či na tvar prostoročasu. Autor se věnuje i nedávnému zachycení gravitačních vln, které Einstein předpověděl v době, kdy neexistovaly nástroje, jak jeho předpověď potvrdit či vyvrátit.
