“那个让物理学变得性感的人……他们称之为下一个斯蒂芬·霍金的科学家。”-时报杂志
摘自《纽约时报》——畅销书《物理学七课》、《时间顺序》和《Helgoland》的作者，这本书更详细地介绍了宇宙扭曲心灵的本质。
世界的基本要素是什么？时间和空间存在吗？现实究竟是什么？理论物理学家卡洛·罗维利一生都在探索这些问题。他告诉我们，几个世纪以来，我们对现实的理解发生了怎样的变化，物理学家们如何看待今天的宇宙结构。
罗维利以优雅易懂的散文带领我们踏上了一段奇妙的旅程，从德谟克利特到阿尔伯特·爱因斯坦，从迈克尔·法拉第到引力波，从经典物理学到他自己在量子引力方面的工作。罗维利向我们展示了现实的概念是如何随着时间的推移而演变的，他对自己在七节简短的物理课中简洁介绍的理论给出了更深入的解释。
本书以对量子引力的清晰概述而告终。量子引力是一个探索时空量子本质的研究领域，旨在统一量子力学和广义相对论。罗维利邀请我们想象一个奇妙的世界，在那里，空间分裂成微小的颗粒，时间以最小的尺度消失，黑洞等待着爆炸——一个巨大的宇宙在很大程度上仍未被发现。
Reality Is Not What It Seems: The Journey to Quantum Gravity (AZW3)
“The man who makes physics sexy . . . the scientist they’re calling the next Stephen Hawking.” —The Times Magazine
From the New York Times–bestselling author of Seven Brief Lessons on Physics, The Order of Time, and Helgoland, a closer look at the mind-bending nature of the universe.
What are the elementary ingredients of the world? Do time and space exist? And what exactly is reality? Theoretical physicist Carlo Rovelli has spent his life exploring these questions. He tells us how our understanding of reality has changed over the centuries and how physicists think about the structure of the universe today.
In elegant and accessible prose, Rovelli takes us on a wondrous journey from Democritus to Albert Einstein, from Michael Faraday to gravitational waves, and from classical physics to his own work in quantum gravity. As he shows us how the idea of reality has evolved over time, Rovelli offers deeper explanations of the theories he introduced so concisely in Seven Brief Lessons on Physics.
This book culminates in a lucid overview of quantum gravity, the field of research that explores the quantum nature of space and time, seeking to unify quantum mechanics and general relativity. Rovelli invites us to imagine a marvelous world where space breaks up into tiny grains, time disappears at the smallest scales, and black holes are waiting to explode—a vast universe still largely undiscovered.
