    Helen Macdonald's bestselling debut H is for Hawk brought the astonishing story of her relationship with goshawk Mabel to global critical acclaim and announced Macdonald as one of this century's most important and insightful nature writers. H is for Hawk won the Samuel Johnson Prize for Nonfiction and the Costa Book Award, and was a finalist for the National Book Critics Circle Award and the Kirkus Prize for Nonfiction, launching poet and falconer Macdonald as our preeminent nature essayist, with a semi-regular column in the New York Times Magazine.In Vesper Flights Helen Macdonald brings together a collection of her best loved essays, along with new pieces on topics ranging from nostalgia for a vanishing countryside to the tribulations of farming ostriches to her own private vespers while trying to fall asleep. Meditating on notions of captivity and freedom, immigration and flight, Helen invites us into her most intimate experiences: observing songbirds from the Empire State Building as they migrate through the Tribute of Light, watching tens of thousands of cranes in Hungary, seeking the last golden orioles in Suffolk's poplar forests. She writes with heart-tugging clarity about wild boar, swifts, mushroom hunting, migraines, the strangeness of birds' nests, and the unexpected guidance and comfort we find when watching wildlife. By one of this century's most important and insightful nature writers, Vesper Flights is a captivating and foundational book about observation, fascination, time, memory, love and loss and how we make sense of the world around us.

    Why is glass see-through? What makes elastic stretchy? Why does a paper clip bend? Why does any material look and behave the way it does? These are the sorts of questions that Mark Miodownik a globally-renowned materials scientist has spent his life exploring In this book he examines the materials he encounters in a typical morning, from the steel in his razor and the graphite in his pencil to the foam in his sneakers and the concrete in a nearby skyscraper.

    We wouldn’t have unraveled DNA or discovered Neptune or figured out how to put 5,000 songs in your pocket. Though many of us were scared away from this essential, engrossing subject in high school and college, Steven Strogatz’s brilliantly creative, down‑to‑earth history shows that calculus is not about complexity; it’s about simplicity. It harnesses an unreal number—infinity—to tackle real‑world problems, breaking them down into easier ones and then reassembling the answers into solutions that feel miraculous. Infinite Powers recounts how calculus tantalized and thrilled its inventors, starting with its first glimmers in ancient Greece and bringing us right up to the discovery of gravitational waves (a phenomenon predicted by calculus). Strogatz reveals how this form of math rose to the challenges of each age: how to determine the area of a circle with only sand and a stick; how to explain why Mars goes “backwards” sometimes; how to make electricity with magnets; how to ensure your rocket doesn’t miss the moon; how to turn the tide in the fight against AIDS. As Strogatz proves, calculus is truly the language of the universe. By unveiling the principles of that language, Infinite Powers makes us marvel at the world anew.

    See ISBN 9780465094646History is full of strange animal stories invented by the brightest and most influential, from Aristotle to Disney. But when it comes to understanding animals, we’ve got a long way to go.Whether we’re watching a viral video of romping baby pandas or looking at a picture of penguins ‘holding hands’, we often project our own values – innocence, abstinence, hard work – onto animals. So you’ve probably never considered that moose get drunk and that penguins are notorious cheats.In The Unexpected Truth About Animals Zoologist Lucy unravels many such myths – that eels are born from sand, that swallows hibernate under water, and that bears gave birth to formless lumps that are licked into shape by their mothers – to show that the stories we create reveal as much about us as they do about the animals.Astonishing, illuminating and laugh-out-loud funny.

    Over the next decade, a handful of scientists, politicians, and strategists, led by two unlikely heroes, risked their careers in a desperate, escalating campaign to convince the world to act before it was too late. Losing Earth is their story, and ours.The New York Times Magazine devoted an entire issue to Nathaniel Rich's groundbreaking chronicle of that decade, which became an instant journalistic phenomenon--the subject of news coverage, editorials, and conversations all over the world. In its emphasis on the lives of the people who grappled with the great existential threat of our age, it made vivid the moral dimensions of our shared plight.Now expanded into book form, Losing Earth tells the human story of climate change in even richer, more intimate terms. It reveals, in previously unreported detail, the birth of climate denialism and the genesis of the fossil fuel industry's coordinated effort to thwart climate policy through misinformation propaganda and political influence. The book carries the story into the present day, wrestling with the long shadow of our past failures and asking crucial questions about how we make sense of our past, our future, and ourselves.Like John Hersey's Hiroshima and Jonathan Schell's The Fate of the Earth, Losing Earth is the rarest of achievements: a riveting work of dramatic history that articulates a moral framework for understanding how we got here, and how we must go forward.

    Extracted from an Afghan mine, the blue “ultramarine” paint used by Michelangelo was so expensive he couldn’t afford to buy it himself. Since ancient times, carmine red—still found in lipsticks and Cherry Coke today—has come from the blood of insects.

    Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

    Dr. Oliver Sacks recounts the stories of patients struggling to adapt to often bizarre worlds of neurological disorder. Here are people who can no longer recognize everyday objects or those they love; who are stricken with violent tics or shout involuntary obscenities; who have been dismissed as autistic or retarded, yet are gifted with uncanny artistic or mathematical talents. If inconceivably strange, these brilliant tales illuminate what it means to be human.

    Ten dimensions? Most of us have barely gotten used to the idea that there are four.Using simple geometry and an easygoing writing style, author Rob Bryanton starts with the lower dimensions that we are all familiar with, then uses those concepts to build one layer upon another, ultimately arriving at a way of imagining the tenth dimension.Part scientific exploration, part philosophy, this unique book touches upon such diverse topics as dark matter, Feynman's "sum over paths", the quantum observer, and the soul. It is aimed at anyone interested in leading-edge theories about cosmology and the nature of reality, but it is not about mainstream physics. Rather, Imagining the Tenth Dimension is a mind-expanding exercise that could change the way you view this incredible universe in which we live.

    And yet for many years it was equally baffling for scientists themselves. Manjit Kumar gives a dramatic and superbly-written history of this fundamental scientific revolution, and the divisive debate at its heart.For 60 years most physicists believed that quantum theory denied the very existence of reality itself. Yet Kumar shows how the golden age of physics ignited the greatest intellectual debate of the twentieth century.Quantum sets the science in the context of the great upheavals of the modern age. In 1925 the quantum pioneers nearly all hailed from upper-middle-class academic families; most were German; and their average age was 24. But it was their irrational, romantic spirit, formed in reaction to the mechanised slaughter of the First World War that inspired their will to test science to its limits.The essential read for anyone fascinated by this complex and thrilling story and by the band of young men at its heart.

    Wilczek’s groundbreaking work in quantum physics was inspired by his intuition to look for a deeper order of beauty in nature. In fact, every major advance in his career came from this intuition: to assume that the universe embodies beautiful forms, forms whose hallmarks are symmetry—harmony, balance, proportion—and economy. There are other meanings of “beauty,” but this is the deep logic of the universe—and it is no accident that it is also at the heart of what we find aesthetically pleasing and inspiring.Wilczek is hardly alone among great scientists in charting his course using beauty as his compass. As he reveals in A Beautiful Question, this has been the heart of scientific pursuit from Pythagoras, the ancient Greek who was the first to argue that “all things are number,” to Galileo, Newton, Maxwell, Einstein, and into the deep waters of twentiethcentury physics. Though the ancients weren’t right about everything, their ardent belief in the music of the spheres has proved true down to the quantum level. Indeed, Wilczek explores just how intertwined our ideas about beauty and art are with our scientific understanding of the cosmos.Wilczek brings us right to the edge of knowledge today, where the core insights of even the craziest quantum ideas apply principles we all understand. The equations for atoms and light are almost literally the same equations that govern musical instruments and sound; the subatomic particles that are responsible for most of our mass are determined by simple geometric symmetries. The universe itself, suggests Wilczek, seems to want to embody beautiful and elegant forms. Perhaps this force is the pure elegance of numbers, perhaps the work of a higher being, or somewhere between. Either way, we don’t depart from the infinite and infinitesimal after all; we’re profoundly connected to them, and we connect them. When we find that our sense of beauty is realized in the physical world, we are discovering something about the world, but also something about ourselves.Gorgeously illustrated, A Beautiful Question is a mind-shifting book that braids the age-old quest for beauty and the age-old quest for truth into a thrilling synthesis. It is a dazzling and important work from one of our best thinkers, whose humor and infectious sense of wonder animate every page. Yes: The world is a work of art, and its deepest truths are ones we already feel, as if they were somehow written in our souls.

    Sound familiar?"(Fritz Lanham, Houston Chronicle) Just as we do today, Americans of the 1890s faced changes in economics, politics, society, and technology that led to wrenching and sometimes violent tensions between rich and poor, capital and labor, white and black, East and West. In The Reckless Decade, H. W. Brands demonstrates that we can learn a lot about the contradictions that lie at the heart of America today by looking at them through the lens of the 1890s. The 1890s saw the closing of the American frontier and a shift toward imperialist ambitions. Populists and muckrakers grappled with robber barons and gold-bugs. Americans addressed the unfinished business of Reconstruction by separating blacks and whites. Booker T. Washington, W. E. B. Du Bois, and other black leaders clashed over the proper response to continuing racial inequality. Those on top of the economic heap—Rockefeller, Carnegie, and Morgan—created vast empires of wealth, while those at the bottom worked for dimes a day. Brands brings all this to life in a vivid narrative filled with larger-than-life characters facing momentous challenges as they worked toward an uncertain future.
