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.

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.

The book emphasizes the importance of physical reasoning and intuitive problem-solving techniques over purely mathematical methods in physics. Aimed at advanced undergraduates, it encourages students to make educated guesses and develop a deeper understanding of complex concepts, preparing them for real-world research challenges. By incorporating contemporary physics topics like Hawking radiation and gravity waves, it offers practical insights into the discipline. Additionally, a solutions manual is available for instructors, enhancing its utility in academic settings.

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.

"Of the four fundamental forces of nature, gravity might be the least understood and yet the one with which we are most intimate. From the months each of us spent suspended in the womb anticipating birth to the moments when we wait for sleep to transport us to other realities, we are always aware of gravity. In On Gravity, physicist A. Zee combines profound depth with incisive accessibility to take us on an original and compelling tour of Einstein's general theory of relativity. Inspired by Einstein's audacious suggestion that spacetime could ripple, Zee begins with the stunning discovery of gravity waves. He goes on to explain how gravity can be understood in comparison to other classical field theories, presents the idea of curved spacetime and the action principle, and explores cutting-edge topics, including black holes and Hawking radiation. Zee travels as far as the theory reaches, leaving us with tantalizing hints of the utterly unknown, from the intransigence of quantum gravity to the mysteries of dark matter and energy. Concise and precise, and infused with Zee's signature warmth and freshness of style, On Gravity opens a unique pathway to comprehending relativity and gaining deep insight into gravity, spacetime, and the workings of the universe"--Publisher's website.
