El último discípulo de Stephen Hawking presenta los más recientes descubrimientos del astrofísico sobre el universo. «Un libro maravilloso sobre el mayor legado de Stephen Hawking». The Spectator Quizá la cuestión más importante que Stephen Hawking abordó en su extraordinaria carrera fue cómo el universo pudo desarrollar las condiciones perfectas para que surgiera la vida. Buscó respuesta en los orígenes del big bang, pero esos trabajos tempranos entraron en crisis, ya que las matemáticas apuntaban hacia la existencia de numerosos big bangs que originaban universos incompatibles con la vida. Encerrados en el departamento de Física teórica de Cambridge, el célebre astrofísico y su amigo y colaborador Thomas Hertog dedicaron veinte años a intentar resolver este enigma y plantear una nueva teoría del cosmos que pudiera explicar el origen de las formas de vida. Al retroceder mucho más en el tiempo, les sorprendió encontrar un nivel más profundo de la evolución en el que las propias leyes físicas se transforman y simplifican hasta que las partículas, las fuerzas e incluso el propio tiempo se desvanecen. Este descubrimiento los llevó a una idea revolucionaria: las leyes de la física no están grabadas en piedra, sino que nacen y evolucionan a medida que el espacio que rigen va tomando forma. Poco antes del fallecimiento del popular físico teórico, la pareja de investigadores publicó su teoría, que proponía una nueva y radical perspectiva darwinista sobre los orígenes de nuestro universo. Sobre el origen del tiempo está llamado a transformar profundamente la forma en la que entendemos nuestro lugar en el cosmos y, en última instancia, puede convertirse en el mayor legado de Hawking. La crítica ha dicho: «Una perspectiva fascinante de una de las mayores búsquedas de la humanidad, por parte de una de sus mentes más destacadas». Christophe Galfard, autor de El universo en tus manos y antiguo alumno de Stephen Hawking «Realmente alucinante... Inmensamente gratificante». The Times «Este libro, magníficamente escrito, nos acerca a un individuo extraordinario, al proceso creativo y al alcance y los límites de nuestra actual comprensión del cosmos». Lord Martin Rees «Una colaboración extraordinaria». The Observer «El libro de Hertog es un fascinante recorrido por la cosmología, la ciencia de los orígenes del universo». Nature

'A wonderful book about Stephen Hawking's biggest legacy' Spectator 'Truly mind-stretching... Immensely rewarding' The Times 'This superbly written book offers insight into an extraordinary individual, the creative process, and the scope and limits of our current understanding of the cosmos' Sir Martin Rees Stephen Hawking's closest collaborator offers the intellectual superstar's final thoughts on the universe. Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. In order to solve this mystery, Hawking studied the big bang origin of the universe, but his early work ran into a crisis when the math predicted many big bangs producing a multiverse - countless different universes, most of which would be far too bizarre to harbour life. Holed up in the theoretical physics department at Cambridge, Stephen Hawking and his friend and collaborator Thomas Hertog worked on this problem for twenty years, developing a new theory of the cosmos that could account for the emergence of life. Peering into the extreme quantum physics of cosmic holograms and venturing far back in time, they were startled to find a deeper level of evolution in which the physical laws themselves transform and simplify until particles, forces, and even time itself fades away. This discovery led them to a revolutionary idea: The laws of physics are not set in stone but are born and co-evolve as the universe they govern takes shape. As Hawking's final days drew near, the two collaborators published their theory, which proposed a radical new Darwinian perspective on the origins of our universe. On the Origin of Time offers a striking new vision of the universe's birth that will profoundly transform the way we think about our place in the order of the cosmos and may ultimately prove to be Hawking's greatest legacy.

One of TIME’s Ten Best Nonfiction Books of the Decade "Meet the new Stephen Hawking . . . The Order of Time is a dazzling book." --The Sunday Times From the bestselling author of Seven Brief Lessons on Physics, Reality Is Not What It Seems, Helgoland, and Anaximander comes a concise, elegant exploration of time. Why do we remember the past and not the future? What does it mean for time to "flow"? Do we exist in time or does time exist in us? In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most readers this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it remains. We think of it as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where at the most fundamental level time disappears. He explains how the theory of quantum gravity attempts to understand and give meaning to the resulting extreme landscape of this timeless world. Weaving together ideas from philosophy, science and literature, he suggests that our perception of the flow of time depends on our perspective, better understood starting from the structure of our brain and emotions than from the physical universe. Already a bestseller in Italy, and written with the poetic vitality that made Seven Brief Lessons on Physics so appealing, The Order of Time offers a profoundly intelligent, culturally rich, novel appreciation of the mysteries of time.

At the end of the nineteenth century, some physicists believed that the basic principles underlying their subject were already known, and that physics in the future would only consist of filling in the details. They could hardly have been more wrong. The past century has seen the rise of quantum mechanics, relativity, cosmology, particle physics, and solid-state physics, among other fields. These subjects have fundamentally changed our understanding of space, time, and matter. They have also transformed daily life, inspiring a technological revolution that has included the development of radio, television, lasers, nuclear power, and computers. In Quantum Generations, Helge Kragh, one of the world's leading historians of physics, presents a sweeping account of these extraordinary achievements of the past one hundred years. The first comprehensive one-volume history of twentieth-century physics, the book takes us from the discovery of X rays in the mid-1890s to superstring theory in the 1990s. Unlike most previous histories of physics, written either from a scientific perspective or from a social and institutional perspective, Quantum Generations combines both approaches. Kragh writes about pure science with the expertise of a trained physicist, while keeping the content accessible to nonspecialists and paying careful attention to practical uses of science, ranging from compact disks to bombs. As a historian, Kragh skillfully outlines the social and economic contexts that have shaped the field in the twentieth century. He writes, for example, about the impact of the two world wars, the fate of physics under Hitler, Mussolini, and Stalin, the role of military research, the emerging leadership of the United States, and the backlash against science that began in the 1960s. He also shows how the revolutionary discoveries of scientists ranging from Einstein, Planck, and Bohr to Stephen Hawking have been built on the great traditions of earlier centuries. Combining a mastery of detail with a sure sense of the broad contours of historical change, Kragh has written a fitting tribute to the scientists who have played such a decisive role in the making of the modern world.

Nations are not trapped by their pasts, but events that happened hundreds or even thousands of years ago continue to exert huge influence on present-day politics. If we are to understand the politics that we now take for granted, we need to understand its origins. Francis Fukuyama examines the paths that different societies have taken to reach their current forms of political order. This book starts with the very beginning of mankind and comes right up to the eve of the French and American revolutions, spanning such diverse disciplines as economics, anthropology and geography. The Origins of Political Order is a magisterial study on the emergence of mankind as a political animal, by one of the most eminent political thinkers writing today.
