One of our great contemporary scientists reveals the 10 profound insights that illuminate what everyone should know about the physical world. 

Virtual reality is genuine reality; that’s the central thesis of Reality+. In a highly original work of “technophilosophy,” David J. Chalmers gives a compelling analysis of our technological future. He argues that virtual worlds are not second-class worlds, and that we can live a meaningful life in virtual reality. We may even be in a virtual world already. 

One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, he examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving. Helgoland is a treeless island in the North Sea where the 23-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution. 

Einstein’s Fridge tells the incredible epic story of the scientists who, over two centuries, harnessed the power of heat and ice and formulated a theory essential to comprehending our universe. “Although thermodynamics has been studied for hundreds of years…few nonscientists appreciate how its principles have shaped the modern world” (Scientific American).

In these brilliant essays, Lightman explores the emotional life of science, the power of imagination, the creative moment, and the alternate ways in which scientists and humanists think about the world. Along the way, he provides in-depth portraits of some of the great geniuses of our time, including Albert Einstein, Richard Feynman, Edward Teller, and astronomer Vera Rubin. Thoughtful, beautifully written, and wonderfully original, A Sense of the Mysterious confirms Alan Lightman's unique position at the crossroads of science and art. 

Searching for Stars on an Island in Maine is the result of these seemingly contradictory impulses, written as an extended meditation on an island in Maine, where Lightman and his wife spend their summers. Framing the dialogue between religion and science as a contrast between absolutes and relatives, Lightman explores our human quest for truth and meaning and the different methods of religion and science in that quest. Along the way, he draws from sources ranging from St. Augustine's conception of absolute truth to Einstein's relativity.

With all the passion, curiosity, and precise yet lyrical prose that have marked his previous books, Alan Lightman here explores the emotional and philosophical questions raised by discoveries in science, focusing most intently on the human condition and the needs of humankind. He looks at the difficult dialogue between science and religion, the conflict between our human desire for permanence and the impermanence of nature, the possibility that our universe is simply an accident, the manner in which modern technology has separated us from direct experience of the world, and our resistance to the view that our bodies and minds can be explained by scientific logic and laws.

One of the most peculiar and possibly unique features of humans is the vast amount of information we carry outside our biological selves. But in our rush to build the infrastructure for the 20 quintillion bits we create every day, we’ve failed to ask exactly why we’re expending ever-increasing amounts of energy, resources, and human effort to maintain all this data. Drawing on deep ideas and frontier thinking in evolutionary biology, computer science, information theory, and astrobiology, Caleb Scharf argues that information is, in a very real sense, alive - an aggregate lifeform.

Carl Zimmer investigates one of the biggest questions of all: What is life? The answer seems obvious until you try to seriously answer it. Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can’t answer that question here on Earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society’s most charged conflicts - whether a fertilized egg is a living person, for example, and when we ought to declare a person legally dead.   

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 listeners, this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it appears. 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.

There is a vast class of things that science has so far almost entirely neglected. They are central to the understanding of physical reality both at an everyday level and at the level of the most fundamental phenomena in physics, yet have traditionally been assumed to be impossible to incorporate into fundamental scientific explanations. They are facts not about what is (the actual) but about what could be (counterfactuals).

The Achaemenid Persian kings ruled over the largest empire of antiquity, stretching from Libya to the steppes of Asia and from Ethiopia to Pakistan. In Persians, historian Lloyd Llewellyn-Jones tells the epic story of this dynasty and the world it ruled. Drawing on Iranian inscriptions, cuneiform tablets, art, and archaeology, he shows how the Achaemenid Persian Empire was the world’s first superpower—one built, despite its imperial ambition, on cooperation and tolerance. This is the definitive history of the Achaemenid dynasty and its legacies in modern-day Iran.

The renowned biologist Paul Nurse has spent his career revealing how living cells work. In What Is Life?, he takes up the challenge of describing what it means to be alive in a way that every listener can understand. It is a shared journey of discovery; step-by-step Nurse illuminates five great ideas that underpin biology - the Cell, the Gene, Evolution by Natural Selection, Life as Chemistry, and Life as Information. 

Cosmos is one of the bestselling science books of all time. In clear-eyed prose, Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space.

What does it mean to “be you” - that is, to have a specific, conscious experience of the world around you and yourself within it? There may be no more elusive or fascinating question. Historically, humanity has considered the nature of consciousness to be a primarily spiritual or philosophical inquiry, but scientific research is now mapping out compelling biological theories and explanations for consciousness and selfhood.
