In this fascinating foray into the centuries-old relationship between science and military power, acclaimed astrophysicist Neil deGrasse Tyson and writer-researcher Avis Lang examine how the methods and tools of astrophysics have been enlisted in the service of war. "The overlap is strong, and the knowledge flows in both directions," say the authors, because astrophysicists and military planners care about many of the same things: multi-spectral detection, ranging, tracking, imaging, high ground, nuclear fusion, and access to space. Tyson and Lang call it a "curiously complicit" alliance.

What would it have been like to be an eyewitness to the Big Bang? In 2014, astronomers wielding BICEP2, the most powerful cosmology telescope ever made, revealed that they'd glimpsed the spark that ignited the Big Bang. Millions around the world tuned in to the announcement broadcast live from Harvard University, immediately igniting rumors of an imminent Nobel Prize. But had these cosmologists truly read the cosmic prologue or, swept up in Nobel dreams, had they been deceived by a galactic mirage?

This is the story of a quest: to find a Theory of Everything. Einstein dedicated his life to seeking this elusive Holy Grail, a single, revolutionary 'god equation' which would tie all the forces in the universe together, yet never found it. Some of the greatest minds in physics took up the search, from Stephen Hawking to Brian Greene. None have yet succeeded. In The God Equation, renowned theoretical physicist Michio Kaku takes the listener on a mind-bending ride through the twists and turns of this epic journey: a mystery that has fascinated him for most of his life.

There was a time when “universe” meant all there is. Everything. Yet, in recent years discoveries in physics and cosmology have led a number of scientists to conclude that our universe may be one among many. With crystal-clear prose and inspired use of analogy, Brian Greene shows how a range of different “multiverse” proposals emerges from theories developed to explain the most refined observations of both subatomic particles and the dark depths of space.

Audie Award, History/Biography, 2016. On the night of July 20, 1969, our world changed forever when Neil Armstrong and Buzz Aldrin walked on the moon. Based on in-depth interviews with 23 of the 24 moon voyagers, as well as those who struggled to get the program moving, A Man on the Moon conveys every aspect of the Apollo missions with breathtaking immediacy and stunning detail.

Science fiction allows us to go places we can only dream of seeing - other worlds, distant stars, entirely different galaxies. While not every story is concerned with the hard science behind space travel and other futuristic ventures, fiction can give us amazing insight into what we could be capable of and what we dream of doing. In these 10 lectures, Professor Erin Macdonald interweaves real science and the achievements of the imagination to reveal the truth that underlies our favorite stories and sheds light on what the future may hold.

This short, smart book tells you everything you need to know about "nothing". What remains when you take all the matter away? Can empty space - "nothing" - exist? To answer these questions, eminent scientist Frank Close takes us on a lively and accessible journey that ranges from ancient ideas and cultural superstitions to the frontiers of current research, illuminating the story of how scientists have explored the void and the rich discoveries they have made there.

The atom. The big bang. DNA. Natural selection. All ideas that have revolutionised science - and that were dismissed out of hand when they first appeared. The surprises haven't stopped: here, Michael Brooks, best-selling author of 13 Things That Don't Make Sense, investigates the new wave of unexpected insights that are shaping the future of scientific discovery. Through 11 radical new insights, Brooks takes us to the extreme frontiers of what we understand about the world.

We all know that without water we couldn't survive, and that sometimes a cup of coffee or a glass of wine feels just as vital. But do we really understand how much we rely on liquids, or the destructive power they hold? Set over the course of a flight from London to San Francisco, Liquid Rules offers listeners a fascinating tour of these formless substances, told through the language of molecules, droplets, heartbeats, and ocean waves.

To better put into perspective the various issues surrounding energy in the 21st century, you need to understand the essential science behind how energy works. And you need a reliable source whose focus is on giving you the facts you need to form your own educated opinions.

What is the nature of space and time? How do we fit within the universe? How does the universe fit within us? There's no better guide through these mind-expanding questions than acclaimed astrophysicist and best-selling author Neil deGrasse Tyson. But today, few of us have time to contemplate the cosmos. So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in digestible chapters consumable anytime and anywhere in your busy day.

We are unprepared for the greatest discovery of modern science. Scientists are confident that there is alien life across the universe yet we have not moved beyond our perception of 'aliens' as Hollywood stereotypes. The time has come to abandon our fixation on alien monsters and place our expectations on solid scientific footing. Using his own expert understanding of life on earth and Darwin's theory of evolution - which applies throughout the universe - Cambridge zoologist Dr Arik Kershenbaum explains what alien life must be like.

There are approximately 25,000 "city killer" asteroids in near-Earth orbit—and most are yet to be found. Small enough to evade detection, they are capable of large-scale destruction, and represent our greatest cosmic threat. But in September 2022, against all odds, NASA's Double Asteroid Redirection Test (DART) mission deliberately crashed a spacecraft into a carefully selected city killer, altering the asteroid's orbit. In How to Kill an Asteroid, award-winning science journalist Robin George Andrews reveals the development of the technology that made it possible

In this 12-lecture masterpiece of scientific reporting, you'll learn everything you need to know to fully grasp the significance of this discovery, including the basics of quantum mechanics; the four forces that comprise the Standard Model of particle physics; how these forces are transmitted by fields and particles; and the importance of symmetry in physics.

Science starts to get interesting when things don'’t make sense. Even today, there are experimental results that the most brilliant scientists can neither explain nor dismiss. In the past, similar anomalies have revolutionised our world: in the 16th century, a set of celestial irregularities led Copernicus to realise that the Earth goes around the sun and not the reverse. In 13 Things That Don'’t Make Sense, Michael Brooks meets thirteen modern-day anomalies that may become tomorrow'’s breakthroughs.

In a field known for startling ideas, the Many-Worlds Interpretation (MWI) of quantum mechanics may take the prize. It holds that parallel to our own world are a large number of other universes, almost identical to ours but with small variations. Copies of each of us inhabit a myriad of these worlds. But they are not us exactly; they share our past history, but they are different people who have unique futures. Although these realms are invisible and can’t communicate with each other, prominent physicists are convinced they must exist.

Michael McCarthy, one of Britain's leading writers on the environment, proposes this joy as a defence of a natural world which is ever more threatened and which, he argues, is inadequately served by the two defences put forward hitherto: sustainable development and the recognition of ecosystem services. Drawing on a wealth of memorable experiences from a lifetime of watching and thinking about wildlife and natural landscapes, McCarthy presents a new way of looking at the world.

The message of modern physics is that physical reality has, at its frontiers, all the aspects of a transcendent order. At the foundation of things, elementary particles can exert instantaneous long-distance influences on each other, can be meaningfully said to have mind-like properties, and can exist in states which are, as Heisenberg wrote, "not quite real, but between the idea of a thing and a real thing."
