Is the future of food looking bleak - or better than ever? At a time when every day brings news of drought and famine, Amanda Little investigates what it will take to feed a hotter, hungrier, more crowded world. She explores the past along with the present and discovers startling innovations: remote-control crops, vertical farms, robot weedkillers, lab-grown meat, 3D-printed meals, water networks run by supercomputers, cloud seeding and sensors that monitor the microclimate of individual plants. She meets the creative and controversial minds changing the face of modern food production, and tackles fears over genetic modification with hard facts. The Fate of Food is a fascinating look at the threats and opportunities that lie ahead as we struggle for food security. Faced with a perilous future, it gives us reason to hope.
There is a long-held view that Wordsworth's inspirations dried up before the age of forty. This book opposes that view by examining the substantial body of poetry written after his fiftieth year. The argument is that, in order to appreciate this work, much of which was inspired by itineraries in Britain and in Europe, we have to read the poems as they were first published. By adopting the perspective of the contemporary reader, Wordsworth's grand design can be appreciated.
FROM THE BESTSELLING AUTHOR OF THE CASE AGAINST SUGAR Conventional weight-loss advice is failing millions of people. For years we've heard the mantra eat less, lose more. And yet, doctors treating diabetes and obesity are experiencing results among patients by taking a different approach: not by counting calories, but by eating a low-carb, high-fat diet. In this explosive, groundbreaking book, Gary Taubes breaks down the nutritional dogma that has led us to the current diabetes and obesity crisis and sets out the case for this ''ketogenic'' approach to eating. Full of eureka moments and essential practical advice, The Case for Keto establishes how many of us can achieve and maintain a healthy weight - for life.
Systems biology came about as growing numbers of engineers and scientists from other fields created algorithms which supported the analysis of biological data in incredible quantities. Whereas biologists of the past had been forced to study one item or aspect at a time, due to technical and biological limitations, it suddenly became possible to study biological phenomena within their natural contexts. This interdisciplinary field offers a holistic approach to interpreting these processes, and has been responsible for some of the most important developments in the science of human health and environmental sustainability. This Very Short Introduction outlines the exciting processes and possibilities in the new field of systems biology. Eberhard O. Voit describes how it enabled us to learn how intricately the expression of every gene is controlled, how signaling systems keep organisms running smoothly, and how complicated even the simplest cells are. He explores what this field is about, why it is needed, and how it will affect our understanding of life, particularly in the areas of personalized medicine, drug development, food and energy production, and sustainable stewardship of our environments. Throughout he considers how new tools are being provided from the fields of mathematics, computer science, engineering, physics, and chemistry to grasp the complexity of the countless interacting processes in cells which would overwhelm the cognitive and analytical capabilities of the human mind. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

What makes mathematics so special? Whether you have anxious memories of the subject from school, or solve quadratic equations for fun, David Acheson's book will make you look at mathematics afresh. Following on from his previous bestsellers, The Calculus Story and The Wonder Book of Geometry, here Acheson highlights the power of algebra, combining it with arithmetic and geometry to capture the spirit of mathematics. This short book encompasses an astonishing array of ideas and concepts, from number tricks and magic squares to infinite series and imaginary numbers. Acheson's enthusiasm is infectious, and, as ever, a sense of quirkiness and fun pervades the book. But it also seeks to crystallize what is special about mathematics: the delight of discovery; the importance of proof; and the joy of contemplating an elegant solution. Using only the simplest of materials, it conjures up the depth and the magic of the subject.
A creative memoir by the 2019 Wellcome Prize winner Will Eaves chronicles a year spent writing a sonata from scratch, in full recognition of the likelihood of failure, to see what can be learned about ambition and limitation. And time. The Point of Distraction explores the way that second-string activities bring one's main interests in life into focus, considering artists as critics, writers as musicians. Staring at your creative pursuit straight on can render it impossible, but if you let it occupy the space of distraction, to your side, it lives and breathes. This novel memoir touches on neuroscience, musical theory and will power.
Sadness is an inevitable part of life, but for most people it will usually alternate or coexist with happy times. Clinical depression, on the other hand, is a mental disorder that causes torment and anguish. It has no moments of relief. It unhinges us from everything we thought we knew about the world and makes us strangers to those we love. It is the predominant mental-health problem worldwide, affecting more than 250 million people. More than a fifth of the population of the UK report symptoms of depression or anxiety. Yet how much do we really know of the condition and of ways to treat it? In MENDING THE MIND, Oliver Kamm recounts what it's like to be mentally ill with severe depression, and he details the route by which, with professional help, he was able to make a full recovery. His experience prompted him to find out all he could about a condition that has afflicted humanity throughout recorded history. He explains the progress of science in understanding depression, and the insights into the condition that have been provided by writers and artists through the ages. His message is hopeful: though depression is a real and devastating illness, the mind and its disorders are yielding to scientific inquiry, and effective psychological, psychiatric and pharmacological treatments are already available. Candid, revelatory and deeply versed in current scientific research, MENDING THE MIND sets out in plain language how the scourge of clinical depression can be countered and may eventually be overcome.
In his highly anticipated sequel to The Elements, Theodore Gray demonstrates how the elements of the periodic table combine to form the molecules that make up our world.Everything physical is made up of the elements and the infinite variety of molecules they form when they combine with each other. In Molecules, Theodore Gray takes the next step in the grand story that began with the periodic table in his best-selling book, The Elements: A Visual Exploration of Every Known Atom in the Universe. Here, he explores through fascinating stories and trademark stunning photography the most interesting, essential, useful, and beautiful of the millions of chemical structures that make up every material in the world.Gray begins with an explanation of how atoms bond to form molecules and compounds, as well as the difference between organic and inorganic chemistry. He then goes on to explore the vast array of materials molecules can create, including: soaps and solvents; goops and oils; rocks and ores; ropes and fibers; painkillers and dangerous drugs; sweeteners; perfumes and stink bombs; colors and pigments; and controversial compounds including asbestos, CFCs, and thimerosal.Big, gorgeous photographs, as well as diagrams of the compounds and their chemical bonds, rendered with never before seen beauty, accompany each discussion.

Here are dinosaurs as you've never seen them before in a dramatically expanded new edition of the book that started the renaissance in dinosaur books. Here are dinosaurs that are swift, stunning, scary and stupendous, presented in a lavish format. Using the latest paleontological research, The New Dinosaurs presents a scientifically accurate look at the way dinosaurs lived: how they moved, ate, dueled, drank and mated. From ten-ton brontosaurus to thirty-foot hadrosaurus, here is a story more fantastic than fantasy itself! The Dinosaurs -- A Fantastic New View of a Lost Era, by William Stout, with narration by the late William Service, is considered to be a classic in illustrated naturalist books. Featured in Life magazine, it helped spark the worldwide interest in dinosaurs that culminated in Jurrasic Park. William Stout's prehistoric life murals are on permanent display at the Houston Museum of Natural Sciences and at Walt Disney's Animal Kingdom. William Service was the author of Owl, which Time magazine called, "one of the most elegant and perceptive pieces of natural writing." Edited by Byron Preiss.
The Sunday Times Science Book of the Year 2017 'Does Einstein proud . . . Eminently readable' Guardian 'No one has covered the topic with such a light touch and joie de vivre . . . a delight' Brian Clegg Gravity was the first force to be recognised and described yet it is still the least understood. If we can unlock its secrets, the force that keeps our feet on the ground holds the key to understanding the biggest questions in science: what is space? What is time? What is the universe? And where did it all come from? Award-winning writer Marcus Chown takes us on an unforgettable journey from the recognition of the 'force' of gravity in 1666 to the discovery of gravitational waves in the twenty-first century. And, as we stand on the brink of a seismic revolution in our worldview, he brings us up to speed on the greatest challenge ever to confront physics.
A new look at the first few seconds after the Big Bang-and how research into these moments continues to revolutionize our understanding of our universe Scientists in recent decades have made crucial discoveries about how our cosmos evolved over the past 13.8 billion years. But we still know little about what happened in the first seconds after the Big Bang. At the Edge of Time focuses on what we have learned and are striving to understand about this mysterious period at the beginning of cosmic history. Delving into the remarkable science of cosmology, Dan Hooper describes many of the extraordinary questions that scientists are asking about the origin and nature of our world. Hooper examines how the Large Hadron Collider and other experiments re-create the conditions of the Big Bang, how we may finally discover the way dark matter was formed during our universe's first moments, and how, with new telescopes, we are lifting the veil on the era of cosmic inflation. At the Edge of Time presents an accessible investigation of our universe and its birth.

"Struggle for a Better South" dispels the notion that all whites in
the South stood united against social change in the 1960s. Gregg
Michel's compelling study of the Southern Student Organizing
Committee (SSOC), the leading progressive organization created by
young white activists in the South during that tumultuous decade,
fills a crucial gap in the literature about New Left activism.
Michel shows that the SSOC was the only activist group of the era
that worked to cultivate white support for the social movement. The
SSOC's members gave themselves the delicate task of reconciling
their love for the South and its history--warts and all--with their
modern-day commitment to equality and justice for all people.
If superheroes stepped off the comic book page, could they actually work their wonders in a world constrained by the laws of physics? How strong would Superman have to be to 'leap tall buildings in a single bound'? Could Storm of the 'X-Men' possibly control the weather? James Kakalios provides an engaging and witty commentary while introducing the lay reader to both classical and cutting-edge concepts in physics, including: what Superman's strength can tell us about the Newtonian physics of force, mass, and acceleration; what villains like Electro and Magneto tell us about electricity and magnetism; how Iceman's powers show the principles of thermal dynamics; what the Human Top can tell us about angular momentum; why physics professors gone bad are the most dangerous evil geniuses... and more!
Nobel Prize winner Heisenberg's classic account explains the central ideas of the quantum revolution and his celebrated Uncertainty Principle.
'This is a book of miracles. Fascinating... An absorbing compendium of unlikely recoveries from physical and mental ailments offers evidence that the brain can heal... brings Oliver Sacks to mind' Lisa Appignanesi, Observer The Brain's Way of Healing explores the astonishing advances in the discovery of neuroplasticity, showing that the brain has its own unique way of healing, only recently uncovered. Norman Doidge discusses a series of remarkable recoveries: patients told they would never improve have years of chronic pain alleviated or damage from debilitating strokes undone, and symptoms of multiple sclerosis, Parkinson's disease, brain injury, autism or learning disorders are reversed. He also shows how the risk of dementia can be lowered by 60%. Using stories to present cutting-edge science, Doidge illustrates principles that everyone can apply to improve their brain's performance.
'Brilliant and fascinating. No one is better at making the recondite accessible and exciting' Bill Bryson Britain's most famous mathematician takes us to the edge of knowledge to show us what we cannot know. Is the universe infinite? Do we know what happened before the Big Bang? Where is human consciousness located in the brain? And are there more undiscovered particles out there, beyond the Higgs boson? In the modern world, science is king: weekly headlines proclaim the latest scientific breakthroughs and numerous mathematical problems, once indecipherable, have now been solved. But are there limits to what we can discover about our physical universe? In this very personal journey to the edges of knowledge, Marcus du Sautoy investigates how leading experts in fields from quantum physics and cosmology, to sensory perception and neuroscience, have articulated the current lie of the land. In doing so, he travels to the very boundaries of understanding, questioning contradictory stories and consulting cutting edge data. Is it possible that we will one day know everything? Or are there fields of research that will always lie beyond the bounds of human comprehension? And if so, how do we cope with living in a universe where there are things that will forever transcend our understanding? In What We Cannot Know, Marcus du Sautoy leads us on a thought-provoking expedition to the furthest reaches of modern science. Prepare to be taken to the edge of knowledge to find out if there's anything we truly cannot know.
'Daring, learned and humane ... A revelatory restoration of wonder' Stephen Greenblatt. We no longer think, like the ancient Chinese did, that the world was hatched from an egg, or, like the Maori, that it came from the tearing-apart of a love embrace. The Greeks told of a tempestuous Hera and a cunning Zeus, but we now use genes and natural selection to explain fear and desire, and physics to demystify the workings of the universe. Science is an astounding achievement, but are we really any wiser than the ancients? Has science revealed the secrets of fate and immortality? Has it provided protection from jealousy or love? There are those who believe that science has replaced faith, but must it also be a death knell for mythology? Evolutions brings to life the latest scientific thinking on the birth of the universe and the solar system, the journey from a single cell all the way to our human minds. Reawakening our sense of wonder and terror at the world around us and within us, Oren Harman uses modern science to create new and original mythologies. Here are the Earth and the Moon presenting a cosmological view of motherhood, a panicking Mitochondrion introducing sex and death to the world, the loneliness of consciousness emerging from the memory of an octopus, and the birth of language in evolution summoning humankind's struggle with truth. Science may not solve our existential puzzles, but like the age-old legends, its magical discoveries can help us continue the never-ending search.
Never before have the four great works of Charles Darwin Voyage of the H.M.S. Beagle (1845), The Origin of Species (1859), The Descent of Man (1871), and The Expression of Emotions in Man and Animals (1872) been collected under one cover. Undertaking this challenging endeavor 123 years after Darwin's death, two-time Pulitzer Prize winner Edward O. Wilson has written an introductory essay for the occasion, while providing new, insightful introductions to each of the four volumes and an afterword that examines the fate of evolutionary theory in an era of religious resistance. In addition, Wilson has crafted a creative new index to accompany these four texts, which links the nineteenth-century, Darwinian evolutionary concepts to contemporary biological thought. Beautifully slipcased, and including restored versions of the original illustrations, From So Simple a Beginning turns our attention to the astounding power of the natural creative process and the magnificence of its products."
