Presents what you need to know about modern physics, the universe and our place in the world in seven lessons. In this introduction to modern physics, the author explains Einstein's theory of general

In this short book, renowned theoretical physicist and author Carlo Rovelli gives a straightforward introduction to Einstein's General Relativity, our current theory of gravitation. Focusing on conceptual clarity, he derives all the basic results in the simplest way, taking care to explain the physical, philosophical and mathematical ideas at the heart of “the most beautiful of all scientific theories”. Some of the main applications of General Relativity are also explored, for example, black holes, gravitational waves and cosmology, and the book concludes with a brief introduction to quantum gravity. Written by an author well known for the clarity of his presentation of scientific ideas, this concise book will appeal to university students looking to improve their understanding of the principal concepts, as well as science-literate readers who are curious about the real theory of General Relativity, at a level beyond a popular science treatment.

暢銷科普作家Carlo Rovelli回溯古希臘哲人阿那克西曼德的驚人思想——地球漂浮於虛空、萬物依自然律演化。這本書不只是科學史，更是一場關於懷疑、探索與知識進化的思辨之旅，啟發我們重新理解科學的靈魂。The bestselling author of Seven Brief Lessons on Physics illuminates the nature of science through the revolutionary ideas of the Greek philosopher Anaximander Over two millennia ago, the prescient insights of Anaximander paved the way for cosmology, physics, geography, meteorology, and biology, setting in motion a new way of seeing the world. His legacy includes the revolutionary ideas that the Earth floats in a void, that animals evolved, that the world can be understood in natural rather than supernatural terms, and that universal laws govern all phenomena. He introduced a new mode of rational thinking with an openness to uncertainty and the progress of knowledge. In this elegant work, the renowned theoretical physicist Carlo Rovelli brings to light the importance of Anaximander's overlooked influence on modern science. He examines Anaximander not from the point of view of a histori

Quantum gravity is perhaps the most important open problem in fundamental physics. It is the problem of merging quantum mechanics and general relativity, the two great conceptual revolutions in the physics of the twentieth century. The loop and spinfoam approach, presented in this 2004 book, is one of the leading research programs in the field. The first part of the book discusses the reformulation of the basis of classical and quantum Hamiltonian physics required by general relativity. The second part covers the basic technical research directions. Appendices include a detailed history of the subject of quantum gravity, hard-to-find mathematical material, and a discussion of some philosophical issues raised by the subject. This fascinating text is ideal for graduate students entering the field, as well as researchers already working in quantum gravity. It will also appeal to philosophers and other scholars interested in the nature of space and time.
