    In the 14 billion years since, scientists have pointed their telescopes upward, peering outward in space and backward in time, developing and refining theories to explain the weird and wonderful phenomena they observed.Through these observations, we now understand concepts like the size of the universe (still expanding), the distance to the next-nearest star from earth (Alpha Centauri, 26 trillion miles) and what drives the formation of elements (nuclear fusion), planets and galaxies (gravity), and black holes (gravitational collapse). But are these cosmological questions definitively answered or is there more to discover?Oxford University astrophysicist and popular YouTube personality Dr. Becky Smethurst presents everything you need to know about the universe in 10 accessible and engaging lessons.In Space at the Speed of Light: The History of 14 Billion Years for People Short on Time, she guides you through fundamental questions, both answered and unanswered, posed by space scientists. Why does gravity matter? How do we know the big bang happened? What is dark matter? Do aliens exist? Why is the sky dark at night? If you have ever looked up at night and wondered how it all works, you will find answers - and many more questions - in this pocket-sized tour of the universe!

    When death is sudden or unexplained, it falls to Shepherd to establish the cause. Each post-mortem is a detective story in its own right - and Shepherd has performed over 23,000 of them. Through his skill, dedication and insight, Dr Shepherd solves the puzzle to answer our most pressing question: how did this person die?From serial killer to natural disaster, 'perfect murder' to freak accident, Shepherd takes nothing for granted in pursuit of truth. And while he's been involved in some of the most high-profile cases of recent times, it's often the less well known encounters that prove the most perplexing, intriguing and even bizarre. In or out of the public eye, his evidence has put killers behind bars, freed the innocent and turned open-and-shut cases on their heads.But a life in death, bearing witness to some of humanity's darkest corners, exacts a price and Shepherd doesn't flinch from counting the cost to him and his family.

    We secretly want to know: could it happen to me? Amanda Montell’s argument is that, on some level, it already has . . .Our culture tends to provide pretty flimsy answers to questions of cult influence, mostly having to do with vague talk of “brainwashing.” But the true answer has nothing to do with freaky mind-control wizardry or Kool-Aid. In Cultish, Montell argues that the key to manufacturing intense ideology, community, and us/them attitudes all comes down to language. In both positive ways and shadowy ones, cultish language is something we hear—and are influenced by—every single day.Through juicy storytelling and cutting original research, Montell exposes the verbal elements that make a wide spectrum of communities “cultish,” revealing how they affect followers of groups as notorious as Heaven’s Gate, but also how they pervade our modern start-ups, Peloton leaderboards, and Instagram feeds. Incisive and darkly funny, this enrapturing take on the curious social science of power and belief will make you hear the fanatical language of “cultish” everywhere.

    So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in tasty chapters consumable anytime and anywhere in your busy day.

    The childhood illness that left her bedridden for a year, which she was not expected to survive. A teenage yearning to escape that nearly ended in disaster. An encounter with a disturbed man on a remote path. And, most terrifying of all, an ongoing, daily struggle to protect her daughter--for whom this book was written--from a condition that leaves her unimaginably vulnerable to life's myriad dangers.Seventeen discrete encounters with Maggie at different ages, in different locations, reveal a whole life in a series of tense, visceral snapshots. In taut prose that vibrates with electricity and restrained emotion, O'Farrell captures the perils running just beneath the surface, and illuminates the preciousness, beauty, and mysteries of life itself.

    In The Missing Lynx, Ross Barnett uses case studies, new fossil discoveries, biomolecular evidence and more to paint pictures of these extinct species, and to explore the significance of the lynx's disappearance in ecological terms. He also discusses how the Britons that these animals shared their home with might have viewed them, and why some survived while others vanished.Barnett also looks in detail and the realistic potential of reintroductions and even of resurrection--topics that capture public interest today. With Beaver now wild again in various parts of Britain and even Great Bustard on Salisbury Plain, what about the return of sabretooths, mammoths, and the aurochs to modern ecosystems? Will we ever be able to bring these animals back? And should we?At a time where rewilding is moving from pie-in-the-sky to actual reality, this timely and important book looks from a scientific perspective at the magnificent megafauna we've lost, why we lost it and what happened as a result, and how we might realistically turn the ecological tide.

    This fascinating collection of historical curiosities explores some of the strangest cases that have perplexed doctors across the world.From seventeenth-century Holland to Tsarist Russia, from rural Canada to a whaler in the Pacific, many are monuments to human stupidity – such as the sailor who swallowed dozens of penknives to amuse his shipmates, or the chemistry student who in 1850 arrived at a hospital in New York with his penis trapped inside a bottle, having unwisely decided to relieve himself into a vessel containing highly reactive potassium. Others demonstrate exceptional surgical ingenuity long before the advent of anaesthesia – such as a daring nineteenth-century operation to remove a metal fragment from beneath a conscious patient’s heart. We also hear of the weird, often hilarious remedies employed by physicians of yore – from crow’s vomit to port-wine enemas – the hazards of such everyday objects as cucumbers and false teeth, and miraculous recovery from apparently terminal injuries.

    Sean Carroll, theoretical physicist and one of this world’s most celebrated writers on science, rewrites the history of 20th century physics. Already hailed as a masterpiece, Something Deeply Hidden shows for the first time that facing up to the essential puzzle of quantum mechanics utterly transforms how we think about space and time. His reconciling of quantum mechanics with Einstein’s theory of relativity changes, well, everything. Most physicists haven’t even recognized the uncomfortable truth: physics has been in crisis since 1927. Quantum mechanics has always had obvious gaps—which have come to be simply ignored. Science popularizers keep telling us how weird it is, how impossible it is to understand. Academics discourage students from working on the "dead end" of quantum foundations. Putting his professional reputation on the line with this audacious yet entirely reasonable book, Carroll says that the crisis can now come to an end. We just have to accept that there is more than one of us in the universe. There are many, many Sean Carrolls. Many of every one of us. Copies of you are generated thousands of times per second. The Many Worlds Theory of quantum behavior says that every time there is a quantum event, a world splits off with everything in it the same, except in that other world the quantum event didn't happen. Step-by-step in Carroll's uniquely lucid way, he tackles the major objections to this otherworldly revelation until his case is inescapably established. Rarely does a book so fully reorganize how we think about our place in the universe. We are on the threshold of a new understanding—of where we are in the cosmos, and what we are made of.

    Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium, and Mare Sirenum—on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science.In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.Johnson’s fascination with Mars began as a child in Kentucky, turning over rocks with her father and looking at planets in the night sky. She now conducts fieldwork in some of Earth’s most hostile environments, such as the Dry Valleys of Antarctica and the salt flats of Western Australia, developing methods for detecting life on other worlds. Here, with poetic precision, she interlaces her own personal journey—as a female scientist and a mother—with tales of other seekers, from Percival Lowell, who was convinced that a utopian society existed on Mars, to Audouin Dollfus, who tried to carry out astronomical observations from a stratospheric balloon. In the process, she shows how the story of Mars is also a story about Earth: This other world has been our mirror, our foil, a telltale reflection of our own anxieties and yearnings.Empathetic and evocative, The Sirens of Mars offers an unlikely natural history of a place where no human has ever set foot, while providing a vivid portrait of our quest to defy our isolation in the cosmos.

    To the right listener, they tell us all about themselves: where they came from, how they lived, how they died - and who killed them. Forensic scientists can unlock the mysteries of the past and help justice to be done using the messages left by a corpse, a crime scene or the faintest of human traces. Forensics uncovers the secrets of forensic medicine, drawing on interviews with top-level professionals, ground-breaking research and Val McDermid's own experience to lay bare the secrets of this fascinating science. And, along the way, she wonders at how maggots collected from a corpse can help determine time of death, how a DNA trace a millionth the size of a grain of salt can be used to convict a killer and how a team of young Argentine scientists led by a maverick American anthropologist uncovered the victims of a genocide.In her crime novels, Val McDermid has been solving complex crimes and confronting unimaginable evil for years. Now, she's looking at the people who do it for real, and real crime scenes. It's a journey that will take her to war zones, fire scenes and autopsy suites, and bring her into contact with extraordinary bravery and wickedness, as she traces the history of forensics from its earliest beginnings to the cutting-edge science of the modern day.
