Science tells us that life elsewhere in the Universe is increasingly likely to be discovered. But in fact the Earth may be a very unusual planet - perhaps the only one like it in the entire visible Universe. In Lucky Planet David Waltham asks why, and comes up with some surprising and unconventional answers. Recent geological, biological, and astronomical discoveries are bringing us closer to understanding whether we might be alone in the Universe, and this book uses these to question the conventional wisdom and suggest, instead, that the Earth may have had 'four billion years of good weather' purely by chance. If Earth-like worlds don't have natural stabilising mechanisms, then intelligent observers such as ourselves will only ever look out onto those rare planets where, like the Earth, all the bad things that could have happened to the climate have fortunately cancelled each other out. So before you prepare to meet the aliens, consider that we are probably alone .
This book puts the debates about the energy-climate continuum on a scientific ground! It is a must-read for everyone, who wants to understand how intimately the energy and climate debates are linked to each other, and who wants to participate in these omnipresent discussions. Antoine Bret explains in his book how fossil fuels became indispensable for our society. He carefully explains how and why this impacts the earth's climate. And he points out that all available fossil fuels will sooner or later be used up. Therefore, he introduces and discusses the alternatives, which are currently considered. The book is divided into three parts. The first part explains the problem and where we stand today, the second part critically discusses possible elements of solution. The third part illustrates historic case studies, containing both warning as well as encouraging examples of societies at turning points. This book is a careful introduction to these topics. The basic science behind the problem and the debates are introduced in an understandable and nicely readable fashion. Facts are illustrated with simple back-on-the-envelope calculations, providing a good feeling for orders of magnitudes. A rich appendix provides additional background information for the interested readers. In this way, the book can even be a valuable resource for introductory university courses in physics, climate science, natural science and many more subjects. This book is a real conversation starter and can be recommended to everyone, specialist or non-specialist, who wants to understand the actual energy-climate debates and maybe even involve.
How do people survive extremes of heat, cold, depth, speed and altitude? This book explores the limits to human survival and the physiological adaptations which enable us to exist under extreme conditions. In man's battle for survival in the harshest of environments, the knowledge imparted by physiology, the 'logic of life', is crucial. What causes mountain sickness? Why is it possible to reach the top of Everest without supplementary oxygen, yet if your plane depressurises suddenly at the same altitude, you're dead? Why are astronauts unable to stand without fainting when they return to Earth? Why do human divers get the Bends but sperm whales don't? Will men always be able to run faster than women? Why don't penguins get frostbite?
For decades after the identification of the structure of DNA, scientists focused only on genes, the regions of the genome that contain codes for the production of proteins. Other regions that make up 98 percent of the human genome were dismissed as "junk," sequences that serve no purpose. But researchers have recently discovered variations and modulations in this junk DNA that are involved with a number of intractable diseases. Our increasing knowledge of junk DNA has led to innovative research and treatment approaches that may finally ameliorate some of these conditions. Junk DNA can play vital and unanticipated roles in the control of gene expression, from fine-tuning individual genes to switching off entire chromosomes. These functions have forced scientists to revisit the very meaning of the word "gene" and have engendered a spirited scientific battle over whether or not this genomic "nonsense" is the source of human biological complexity. Drawing on her experience with leading scientific investigators in Europe and North America, Nessa Carey provides a clear and compelling introduction to junk DNA and its critical involvement in phenomena as diverse as genetic diseases, viral infections, sex determination in mammals, and evolution. We are only now unlocking the secrets of junk DNA, and Nessa Carey's book is an essential resource for navigating the history and controversies of this fast-growing, hotly disputed field.
The naturalist Gilbert White (1720-93) was known for his meticulous observations of flora and fauna in their natural environment, primarily around his village of Selborne in Hampshire. This posthumous 1795 publication, edited by the physician and writer John Aikin (1747-1822), comprises a collection of extracts from White's previously unpublished papers from 1768 to his death. Presented here for 'lovers of natural knowledge' is a full year of White's observations. Following the month-by-month record of natural events, the book contains brief studies of birds, quadrupeds, insects, plants and the weather. A lifelong lover of the outdoors, White had kept a near daily record of his activities for more than forty years. Regarded as one of the fathers of ecology, inspiring others to appreciate the natural world, White is best known for The Natural History and Antiquities of Selborne (1789), which is also reissued in the Cambridge Library Collection.
Creation and access to green spaces promotes individual human health, especially in therapeutic contexts among those suffering traumatic events. But what of the role of access to green space and the act of creating and caring for such places in promoting social health and well-being? Greening in the Red Zone asserts that creation and access to green spaces confers resilience and recovery in systems disrupted by violent conflict or disaster. This edited volume provides evidence for this assertion through cases and examples. The contributors to this volume use a variety of research and policy frameworks to explore how creation and access to green spaces in extreme situations might contribute to resistance, recovery, and resilience of social-ecological systems.
'If you've ever wondered why we keep secrets and what motivates us to spill them, look no further' Adam Grant, #1 New York Times bestselling author of Think Again An eye-opening look at why we keep the secrets we keep, how to better understand and cope with them, and when (and how) we should bring them to light. Think of a secret that you're keeping from others. It shouldn't take long. Psychologist Michael Slepian finds that, on average, we are keeping as many as thirteen secrets at any given time. His research, involving more than 50,000 participants from around the world, shows that we most frequently keep secrets about lies we've told, ambitions, addictions, mental health challenges, hidden relationships and financial struggles. Our secrets can weigh heavily upon us. Yet the burden of secrecy rarely stems from the work it takes to keep a secret hidden. Rather, the weight of our secrets comes from carrying them alone. Whether we are motivated to protect our reputation, a relationship, a loved one's feelings, or some personal or professional goal, one thing is clear: holding back some part of our inner world is often lonely and isolating. But it doesn't have to be. Filled with fresh insight into one of the most universal - yet least understood - aspects of human behaviour, The Secret Life of Secrets sheds fascinating new light on questions like: At what age do children develop the cognitive capacity for secrecy? Do all secrets come with the same mental load? How can we reconcile our secrets with our human desires to relate, connect and be known? When should we confess and to whom? And can keeping certain types of secrets actually enhance our well-being? Drawing on over a decade of original research, this book reveals the surprising ways in which secrets pervade our lives, and offers science-based strategies that make them easier to live with. The result is a rare window into the inner workings of our minds, our relationships and our sense of who we are.
As a result of the COVID-19 pandemic, medical statistics and public health data have become staples of newsfeeds worldwide, with infection rates, deaths, case fatality and the mysterious R figure featuring regularly. However, we don't all have the statistical background needed to translate this information into knowledge. In this lively account, Stephen Senn explains these statistical phenomena and demonstrates how statistics is essential to making rational decisions about medical care. The second edition has been thoroughly updated to cover developments of the last two decades and includes a new chapter on medical statistical challenges of COVID-19, along with additional material on infectious disease modelling and representation of women in clinical trials. Senn entertains with anecdotes, puzzles and paradoxes, while tackling big themes including: clinical trials and the development of medicines, life tables, vaccines and their risks or lack of them, smoking and lung cancer, and even the power of prayer.
The Sunday Times bestselling guide to using the science of the body clock to create your optimum personal routine: sleep better, work better and feel better. In the twenty-first century, we increasingly push our daily routines into the night, carrying out work, exercise and our social lives long after dark. But we have forgotten that our bodies are governed by a 24-hour biological clock which guides us towards the best time to sleep, eat and think. In Life Time, Professor Russell Foster shares his life's work, taking us on a fascinating and surprising journey through the science of our body clocks. Using his own studies, as well as insights from an international community of sleep scientists and biologists studying circadian rhythms, he illustrates the surprising effects the time of day can have on our health: how a walk outside at dawn can ensure a better night's sleep, how eating after sundown can affect our weight, and the extraordinary effects the time we take our medication can have on our risk of life-threatening conditions, such as strokes. With knowledge of this astonishing science, we can get back into the rhythm, and live healthier, sharper lives.
Why use expensive beauty products when you can moisturise with jellyfish? Have you ever suspected pollution was to blame for your children's plummeting IQ? Ready to take a sea change . . . on Mars? And how about chopping an onion that doesn't make you cry? This is the perfect present for enquiring minds. Compelling, quirky and packed fully of curious facts, The Naked Scientist: Life Under the Microscope is a treasure trove of cutting-edge research, far-flung factoids and the ability to see into our scientific future, answering those fascinating questions you never thought to ask.
The main topic of the book is a reconstruction of the evolution of nervous systems and brains as well as of mental-cognitive abilities, in short "intelligence" from simplest organisms to humans. It investigates to which extent the two are correlated. One central topic is the alleged uniqueness of the human brain and human intelligence and mind. It is discussed which neural features make certain animals and humans intelligent and creative: Is it absolute or relative brain size or the size of "intelligence centers" inside the brains, the number of nerve cells inside the brain in total or in such "intelligence centers" decisive for the degree of intelligence, of mind and eventually consciousness? And which are the driving forces behind these processes? Finally, it is asked what all this means for the classical problem of mind-brain relationship and for a naturalistic theory of mind.
FULLY UPDATED FOR 2019 We cannot live without water. But with 7.5 billion people competing for this single unevenly-distributed resource, the planet is drying up. In When the Rivers Run Dry, Fred Pearce explores the growing world water crisis, from Kent to Kenya. His powerful reportage takes us to places where waterways are turning to sand before they reach the ocean; where fields are parched and crops no longer grow; where once fertile ground has turned to desert; where wars are fought over access to water and cultures are dying out. But he offers us hope for the future - if we can radically revolutionise the way we treat water, and take personal responsibility for the water we use. This landmark work, from a respected and accomplished scientist, will transform the way we view the water in our reservoirs and rivers, and change the way we treat the water in our taps.
John K. DeLaski, M.D. practiced medicine in the Penobscot Bay region of Maine and, in addition, was a naturalist with keen powers of observation. His study of the landscape led to the conclusion that a thick glacier had overtopped the highest hills, flooded all of Penobscot Bay, extended far to the east and west and probably was part of a greater continental glacier. He published these very critical field observations and inferences in numerous articles in local newspapers and magazines, and in the American Journal of Science in 1864. His work put him on the "team" of Benjamin Silliman, James D. Dana and Louis Agassiz as an advocate for glaciation as the regional land shaping force opposed to that of the Biblical Deluge, a major scientific conflict of the day both in North America and Europe. He remained a shadowy player, in the background, but clearly contributed critical observations to the argument through personal interactions with Agassiz and other prominent naturalists. They incorporated DeLaski's observations into their own presentations, often without giving him credit. John DeLaski's summary work, a 400 page handwritten manuscript for the book, "The Ancient Great Glacier of North America", was dated 1869. He died in 1874 and the book was not published. The historic significance of DeLaski's unpublished book is based upon its startling contribution to one of the major scientific questions of the day of whether the surficial geology of northern U.S. and Canada was caused by the actions of the Biblical Flood or by continental glaciation. If published, this would have been the first book on this continent, at least, to present a holistic discussion of the controversy in which he presented his critical observations of the surficial geology in Maine, southern New England and New Brunswick, Canada and concluded that these depositional and erosional features must be of glacial origin. DeLaski then incorporated other evidence into the book for glaciation reported by others from the region during a decade or two, and from the mid and far west and Canada to advocate that the entire region was covered by an ice sheet that was at least 5,000 feet and probably much thicker over interior northern U.S. and Canada and which terminated along a glacial margin which extended from southern new England as far westward along the courses of the Ohio, and Missouri Rivers. All this was done while most "naturalists" still advocated the Biblical Flood to explain the major components of the surficial geology in North America and abroad. DeLaski's book containing his critical observations of clearly so many landscape features of glacial origin, if published would have been a pivotal document that would have strongly supported those arguing for glaciations in the glaciations vs. flood international argument.
A savory account of how the pursuit of delicious foods shaped human evolution Nature, it has been said, invites us to eat by appetite and rewards by flavor. But what exactly are flavors? Why are some so pleasing while others are not? Delicious is a supremely entertaining foray into the heart of such questions. With generous helpings of warmth and wit, Rob Dunn and Monica Sanchez offer bold new perspectives on why food is enjoyable and how the pursuit of delicious flavors has guided the course of human history. They consider the role that flavor may have played in the invention of the first tools, the extinction of giant mammals, the evolution of the world's most delicious and fatty fruits, the creation of beer, and our own sociality. Along the way, you will learn about the taste receptors you didn't even know you had, the best way to ferment a mastodon, the relationship between Paleolithic art and cheese, and much more. Blending irresistible storytelling with the latest science, Delicious is a deep history of flavor that will transform the way you think about human evolution and the gustatory pleasures of the foods we eat.
Metaphysics isn't ordinarily much of a laughing matter. But in the hands of acclaimed comedy writer and scholar Eric Kaplan, a search for the truth about old St. Nick becomes a deeply insightful, laugh-out-loud discussion of the way some things exist but may not really be there. Just like Santa and his reindeer. Even after we outgrow the jolly fellow, the essential paradox persists: There are some things we dearly believe in that are not universally acknowledged as real. In Does Santa Exist? Kaplan shows how philosophy giants Bertrand Russell and Ludwig Wittgenstein strove to smooth over this uncomfortable meeting of the real and unreal - and failed. From there he turns to mysticism's attempts to resolve such paradoxes, surveying Buddhism, Taoism, early Christianity, Theosophy and even the philosophers at UC Berkeley under whom he studied. Finally, this brilliant comic writer alights on - surprise! - comedy as the ultimate resolution of the fundamental paradoxes of life, using examples from The Big Bang Theory, Monty Python's cheese shop and many other pop-culture sources. Kaplan delves deeper into what all this means, from how our physical brains work to his own personal confrontations with life's biggest questions: If we're all going to die, what's the point of anything? What is a perfect moment? What can you say about God? Or Santa?
In China, lots of excellent maths students takes an active part in various maths contests and the best six senior high school students will be selected to form the IMO National Team to compete in the International Mathematical Olympiad. In the past ten years, China's IMO Team has achieved outstanding results - they have won the first place almost every year.The author is one of the senior coaches of China's IMO National Team, he is the headmaster of Shanghai senior high school which is one of the best high schools of China. In the past decade, the students of this school have won the IMO gold medals almost every year.The author attempts to use some common characteristics of sequence and mathematical induction to fundamentally connect Math Olympiad problems to particular branches of mathematics. In doing so, the author hopes to reveal the beauty and joy involved with math exploration and at the same time, attempts to arouse readers' interest of learning math and invigorate their courage to challenge themselves with difficult problems.
In the very successful and widely discussed first volume in the Golem series, The Golem: What You Should Know about Science, Harry Collins and Trevor Pinch likened science to the Golem, a creature from Jewish mythology, a powerful creature which, while not evil, can be dangerous because it is clumsy. In this second volume, the authors now consider the Golem of technology. In a series of case studies they demonstrate that the imperfections in technology are related to the uncertainties in science described in the first volume. The case studies cover the role of the Patriot anti-missile missile in the Gulf War, the Challenger space shuttle explosion, tests of nuclear fuel flasks and of anti-misting kerosene as a fuel for airplanes, economic modeling, the question of the origins of oil, analysis of the Chernobyl nuclear disaster, and the contribution of lay expertise to the analysis of treatments for AIDS.
In this book, first published in 2006, seven internationally renowned writers address the theme of Power from the perspective of their own disciplines. Energy expert Mary Archer begins with an exploration of the power sources of our future. Astronomer Neil Tyson leads a tour of the orders of magnitude in the cosmos. Mathematician and inventor of the Game of Life John Conway demonstrates the power of simple ideas in mathematics. Screenwriter Maureen Thomas explains the mechanisms of narrative power in the media of film and videogames, Elisabeth Bronfen the emotional power carried by representations of life and death, and Derek Scott the power of patriotic music and the mysterious Mozart effect. Finally, celebrated parliamentarian Tony Benn critically assesses the reality of power and democracy in society.
A user's guide to the solar revolution - and why we must all get on board, before it is too late. We are a cusp civilisation. In just over three generations, we have consumed approximately half the useful oil which took photosynthesis around two million years to produce. In approximately two generations we have used around half our useful uranium resources. We are faced with an urgent choice, the roots of which, Keith Barnham explains, lies in 1905 with the discovery of Einstein's 'other' equation, E = hf. By an extraordinary coincidence, this little-known equation, which began the quantum revolution and could hold the key to our future survival through the generation of electricity from sunlight, was discovered in the same year as E = mc2, the equation that threatens to destroy us. This book will investigate the reasons why scientists exploited the equation E = mc2 for energy generation much faster than E = hf, putting our civilisation on an ever-sharper knife edge. But THE BURNING ANSWER is as much about solutions as problems. Through his groundbreaking research, Keith Barnham offers the controversial promise that, despite our much higher energy demands now than in earlier periods of human evolution, our sun can provide all our primary energy needs again. The sunlight falling on the earth in one hour is more than enough to supply all the energy demands of humankind for one year. This solar technology can save us from the threats of global warming, diminishing oil resources, and nuclear disaster -- provided we don't allow politics to stand in our way.

Influenza, AIDS, and Ebola: Viruses are normally defined as pathogens. Most viruses are, however, not enemies or killers. Well-known virologist and cancer researcher Karin Moelling describes surprising insights about a completely new and unexpected world of viruses. Viruses are ubiquitous, in the oceans, our environment, in animals, plants, bacteria, in our body, even in our genomes. They influence our weather, can contribute to control obesity, and can surprisingly be applied against threatening multi-resistant bacteria. The success story of the viruses started more than 3.5 billion years ago in the dawn of life when even cells did not exist. They are the superpower of life. There are more viruses on earth than stars in the sky. Viruses are everywhere. Some of them are incredibly ancient. Many viruses are hundredfold smaller than bacteria, but others are tenfold bigger and they were discovered only recently - the giant viruses, even deep within the permafrost where they were reactivated after 30,000 years.The author talks about a completely new world of viruses, which are based on the most recent, in part her own research results. Could viruses have been our oldest ancestors? Have viruses even 'invented' social behavior, do they lead to geniuses such as Mozart or Einstein - or alternatively to cancer? They can help to cure cancer. In this book, the author made a clear distinction between what is fact and what is her vision. This book is written for a general audience and not just for the experts. Its aim is to stimulate thinking, and perhaps to attract more young scientists to enter this field of research.
The American social historian and antiquarian Alice Morse Earle (1851-1911) published this lavishly illustrated book, among the last of her works, in 1902. By this time she had developed a distinctive style of historical writing which made innovative use of material evidence in its focus on the details of everyday life. She was particularly interested in family and society in colonial America, and her views about the importance of ancestry were reflected in her membership of the National Society of the Daughters of the American Revolution. Her fascination for beautiful things found lively expression in this learned and charming exploration of two 'garden delights'. Drawing readily on folklore, literature and anecdote, Earle brings to life her history of sundials and roses in Europe and America, touching on practical, aesthetic and symbolic aspects.
Thomas Bewick (1753-1828) is synonymous with finely crafted wood engravings of the natural world, and his instantly recognisable style influenced book illustration well into the nineteenth century. During his childhood in the Tyne valley, his two obsessions were art and nature. At fourteen, he was apprenticed to the engraver and businessman Ralph Beilby (1743-1817) with whom he later published A General History of Quadrupeds (also reissued in this series). The present work, with its text compiled from various sources, was the first practical field guide for the amateur ornithologist, inspiring also artists and writers. Each of the two volumes contains hundreds of illustrations of breathtaking beauty and precision: one for each species, neatly capturing its character in exquisite detail, interspersed with charming vignettes of country life. Volume 1, first published in 1797, covers land birds, including eagles, owls, sparrows and finches.
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, bestselling 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 eleven radical new insights, Brooks takes us to the extreme frontiers of what we understand about the world. He journeys from the observations that might rewrite our history of the universe, through the novel biology behind our will to live, and on to the physiological root of consciousness. Along the way, he examines how the underrepresentation of women in clinical trials means that many of the drugs we use are less effective on women than men and more likely to have adverse effects, explores how merging humans with other species might provide a solution to the shortage of organ donors, and finds out if there is such a thing as the will to live. When we think about science, we often think of iron-clad facts. But today more than ever, our unshakeable truths have been shaken apart. As Michael Brooks reveals, the best science is about open-mindedness, imagination and a love of mind-boggling adventures at the edge of uncertainty. |
