“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 and The Order of Time, 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.

'A dazzling book ... the new Stephen Hawking' Sunday Times The bestselling author of Seven Brief Lessons on Physics takes us on an enchanting, consoling journey to discover the meaning of time 'We are time. We are this space, this clearing opened by the traces of memory inside the connections between our neurons. We are memory. We are nostalgia. We are longing for a future that will not come.' Time is a mystery that does not cease to puzzle us. Philosophers, artists and poets have long explored its meaning while scientists have found that its structure is different from the simple intuition we have of it. From Boltzmann to quantum theory, from Einstein to loop quantum gravity, our understanding of time has been undergoing radical transformations. Time flows at a different speed in different places, the past and the future differ far less than we might think, and the very notion of the present evaporates in the vast universe. With his extraordinary charm and sense of wonder, bringing together science, philosophy and art, Carlo Rovelli unravels this mystery. Enlightening and consoling, The Order of Time shows that to understand ourselves we need to reflect on time -- and to understand time we need to reflect on ourselves.

This book deals with applications of quantum mechanical techniques to areas outside of quantum mechanics, so-called quantum-like modeling. Research in this area has grown over the last 15 years. But even already more than 50 years ago, the interaction between Physics Nobelist Pauli and the psychologist Carl Jung in the 1950's on seeking to find analogous uses of the complementarity principle from quantum mechanics in psychology needs noting. This book does NOT want to advance that society is quantum mechanical! The macroscopic world is manifestly not quantum mechanical. But this rules not out that one can use concepts and the mathematical apparatus from quantum physics in a macroscopic environment. A mainstay ingredient of quantum mechanics, is 'quantum probability' and this tool has been proven to be useful in the mathematical modelling of decision making. In the most basic experiment of quantum physics, the double slit experiment, it is known (from the works of A. Khrennikov) that the law of total probability is violated. It is now well documented that several decision making paradoxes in psychology and economics (such as the Ellsberg paradox) do exhibit this violation of the law of total probability. When data is collected with experiments which test 'non-rational' decision making behaviour, one can observe that such data often exhibits a complex non-commutative structure, which may be even more complex than if one considers the structure allied to the basic two slit experiment. The community exploring quantum-like models has tried to address how quantum probability can help in better explaining those paradoxes. Research has now been published in very high standing journals on resolving some of the paradoxes with the mathematics of quantum physics. The aim of this book is to collect the contributions of world's leading experts in quantum like modeling in decision making, psychology, cognition, economics, and finance.

Former British Ambassador to the Soviet Union and author of the definitive account of the Soviet invasion and occupation of Afghanistan, Sir Rodric Braithwaite offers here a tour d'horizon of nuclear policy from the end of World War II and start of the Cold War to the present day. Armageddon and Paranoia unfolds the full history of nuclear weapons that began with the arms race between the United States and the Soviet Union and now extends worldwide. For decades, an apocalypse seemed imminent, staved off only by the certainty that if one side launched these missiles the other would launch an equally catastrophic counterstrike. This method of avoiding all-out nuclear warfare was called "Deterrence," a policy of Mutually Assured Destruction (MAD). Still, though neither side actively wanted to plunge the world into nuclear wasteland, the possibility of war by misjudgment or mistake meant fears could never be entirely assuaged. Both an exploration of Deterrence and the long history of superpower nuclear policy, Armageddon and Paranoia comes at a time when tensions surrounding nuclear armament have begun mounting once more. No book until this one has offered so comprehensive a history of the topic that has guided--at times dominated--the world in which we live.

"Changing Energy outlines how humanity came to its current energy economy through three previous energy transitions and now stands poised for a necessary fourth one. Despite the immense benefits conferred by a global energy economy based primarily on coal, oil, gas, and uranium, societies must now rebuild their energy economies to rely as much as possible on renewable energy used efficiently. This imperative to change comes from the risks of climate change plus the dangers of geopolitical tensions, health and environmental effects, and the long-term prospects for ever depleting sources of today's energy sources. Changing Energy argues that sustainability of the benefits from energy services will come from investments made in the technologies of the fourth transition. Perkins envisions a viable post-fossil fuel energy economy and outlines the barriers that must be resolved to reach it."--Provided by publisher.

Compelling reading, this book both reinforces and elevates the role of art in the exploration and analysis of the concepts of democracy, globalization and capitalism. In the book, the author describes a post-human world, a state we have already entered. But how should we think about it, given we have already been co-opted? Can we articulate the future outside the false discipline that the market often dictates, beyond the clutches of a few social media companies, and maintain our rich diversities while holding on to those things that make life possible and worthwhile: love, hope and art? Running throughout the book is the central theme of uncertainty and divergence. It is uncompromising in asking the question about the need for a new global creation story, which has at its core not the certainties of one defined creation myth but the need to feel comfortable with the uncertainty principle both in physics and the political economy. It is up to artists, scientists and philosophers to articulate this wonder and to help us write a new global creation story based on art (the arts), uncertainty, diversity, risk and wonder – and of course knowledge. This book has the capacity to both clarify and re-shape your thinking.

'This witty book reveals the humbling vastness of our ignorance about the universe, along with charming insights into what we actually do understand' Carlo Rovelli, author of Seven Brief Lessons on Physics and Reality Is Not What It Seems In our small corner of the universe, we know how some matter behaves most of the time and what even less of it looks like, and we have some good guesses about where it all came from. But we really have no clue what's going on. In fact, we don't know what about 95% of the universe is made of. So what happens when a cartoonist and a physicist walk into this strange, mostly unknown universe? Jorge Cham and Daniel Whiteson gleefully explore the biggest unknowns, why these things are still mysteries, and what a lot of smart people are doing to figure out the answers (or at least ask the right questions). While they're at it, they helpfully demystify many complicated things we do know about, from quarks and neutrinos to gravitational waves and exploding black holes. With equal doses of humour and delight, they invite us to see the universe as a vast expanse of mostly uncharted territory that's still ours to explore. This is a book for fans of Brian Cox and What If. This highly entertaining highly illustrated book is perfect for anyone who's curious about all the great mysteries physicists are going to solve next.
