The hunt for the Higgs particle has involved the biggest, most expensive experiment ever. So exactly what is this particle? Why does it matter so much? What does it tell us about the universe? Was finding it really worth all the effort? The short answer is yes. The Higgs field is proposed as the way in which particles gain mass - a fundamental property of matter. It's the strongest indicator yet that the Standard Model of physics really does reflect the basic building blocks of our universe. Little wonder the hunt and discovery of this new particle produced such intense media interest.

Nobel laureate Erwin Schrödinger's What is Life? is one of the great science classics of the 20th century. A distinguished physicist's exploration of the question which lies at the heart of biology, it was written for the layman but proved one of the spurs to the birth of molecular biology and the subsequent discovery of the structure of DNA. It appears here together with "Mind and Matter", his essay investigating a relationship which has eluded and puzzled philosophers since the earliest times.

Of the codified laws of nature, only one inscribes a direction to time: the dreaded second law of thermodynamics, which declares that the disorder of a closed system tends to increase as time passes. New shoes eventually scuff, our bodies weaken and die. Yet our senses tell us that miraculous order constantly emerges, too: children grow and learn; spontaneous patterns manifest in murmurations of starlings. Can it be true that the laws of our universe mandate only dissolution?

Award-winning author and mathematician Joseph Mazur provides an engaging exploration of how the understanding of time has evolved throughout human history and offers a compelling new vision, submitting that time lives within us. Our cells, he notes, have a temporal awareness, guided by environmental cues in sync with patterns of social interaction. Listeners learn that, as a consequence of time's personal nature, a 48-hour journey on the Space Shuttle can feel shorter than a six-hour trip on the Soyuz capsule and that the Amondawa of the Amazon do not have ages.

Erika Hamden, a renowned astrophysicist and educator, brings her passion for space to life in this engaging book. With years of experience studying the cosmos, Hamden specializes in making complex topics fun and easy to understand.

In this visionary book, Dr. Tim Gregory challenges prevailing narratives around climate change, arguing that the goal of net zero is not simply to replace fossil fuels with renewables, but to power civilization using sources of energy that do not emit carbon dioxide. He unequivocally shows that only one emissions-free energy source can rise to that challenge: nuclear power.

At last, science and the soul shake hands. Writing in a style that is both lucid and charming, mischievous and profound, Dr. Amit Goswami uses the language and concepts of quantum physics to explore and scientifically prove metaphysical theories of reincarnation and immortality. In Physics of the Soul, Goswami helps listeners understand the perplexities of the quantum physics model of reality and the perennial beliefs of spiritual and religious traditions.

Throughout history, scientists have come up with theories and ideas that just don't seem to make sense. These we call paradoxes. The paradoxes Al-Khalili offers are drawn chiefly from physics and astronomy and represent those that have stumped some of the finest minds. With elegant explanations that bring the listener inside the mind of those who've developed them, Al-Khalili helps us to see that, in fact, paradoxes can be solved if seen from the right angle.

In this thought-provoking exploration, physicists Chris Ferrie and Geraint F. Lewis delve into the fundamental questions that have puzzled humanity for centuries. With clarity and precision, Ferrie and Lewis navigate the realms of quantum physics, relativity, and cosmology, providing accessible explanations that engage both novices and enthusiasts.

Goswami's basic premise is that quantum physics is not only the future of science, but is also the key to understanding consciousness, life, death, God, psychology, and the meaning of life. Quantum physics is an antidote to the moral sterility and mechanistic approach of scientific materialism and is the best and clearest approach to understanding our universe. In short, quantum physics is indeed the theory of everything.

Growing up in suburban Detroit, David Hahn was fascinated by science. While he was working on his Atomic Energy badge for the Boy Scouts, David's obsessive attention turned to nuclear energy. Throwing caution to the wind, he plunged into a new project: building a model nuclear reactor in his backyard garden shed. Posing as a physics professor, David solicited information on reactor design from the US government and from industry experts. Following blueprints he found in an outdated physics textbook, David cobbled together a crude device that threw off toxic levels of radiation.

Astrophysics For Dummies breaks it all down for you, making this difficult but fascinating topic accessible to anyone. Tracking the topics covered in a typical undergraduate astrophysics class, this book will teach you the essential pieces to understanding our universe. Get ready to launch into outer space with this ever-changing branch of science.

This Very Short Introduction presents the field of fluid mechanics by focusing on the underlying physical ideas and using everyday phenomena to demonstrate them, from dripping taps to swimming ducks. Eric Lauga shows how this set of fundamental physical concepts can be applied to a wide range of flow behaviors and highlights the role of fluid motion in both the natural and industrial worlds. This book also considers future applications of fluid mechanics in science.

In the 18th century, the British minister and mathematician Thomas Bayes devised a theorem that allowed him to assign probabilities to events that had never happened before. It languished in obscurity for centuries until computers came along and made it easy to crunch the numbers. Now, as the foundation of big data, Bayes's formula has become a linchpin of the digital economy. But here's where things get interesting: Bayes's theorem can also be used to lay odds on the existence of extraterrestrial intelligence, and on the biggest question of all: how long will humanity survive?

If you've ever found yourself fascinated by the idea of quantum computing but feel a little overwhelmed by the mind-blowing subject of quantum mechanics or concerned by climate change but haven't been able to get to grips with the details of global warming, this book is for you.

The most important things in life are our health and happiness. Yet most of us are neither healthy nor happy. We have been led to believe that if we think ahead and make the right choices, we can manifest our dreams. Yet despite our best efforts, we still have more disease and discontent than ever before. Is it possible that our essential ideas about life are flawed? We are all aware of the impact of sunlight on a plant's growth and development. But few of us realize that a plant actually "sees" where light is emanating from and positions itself to be in optimal alignment with it.

Increasingly, cracks are appearing in the capacity of communities, ecosystems, and landscapes to provide the goods and services that sustain our planet's well-being. The response from most quarters has been for "more of the same" that created the situation in the first place: more control, more intensification, and greater efficiency. "Resilience thinking" offers a different way of understanding the world and a new approach to managing resources. It embraces human and natural systems as complex entities continually adapting through cycles of change.

An exhilarating tour of the contemporary quantum landscape, Beyond Weird is a book about what quantum physics really means - and what it doesn't. Science writer Philip Ball offers an up-to-date, accessible account of the quest to come to grips with the most fundamental theory of physical reality, and to explain how its counterintuitive principles underpin the world we experience.

In this Very Short Introduction, William Lowrie describes the internal and external processes that affect the planet, as well as the principles and methods of geophysics used to investigate them. From analyses of Earth's deepest interior to measurements made from Earth-orbiting satellites, Lowrie shows how geophysical exploration is vitally important in the search for mineral resources and emphasizes our need to understand the history of our planet and the processes that govern its continuing evolution.

In the beginning was the Big Bang: an unimaginably hot fire almost fourteen billion years ago in which the first elements were forged. The physical theory of the hot nascent universe—the Big Bang—was one of the most consequential developments in twentieth-century science. And yet it leaves many questions unanswered: Why is the universe so big? Why is it so old? What is the origin of structure in the cosmos? In An Infinity of Worlds, physicist Will Kinney explains a more recent theory that may hold the answers to these questions and even explain the ultimate origins of the universe.
