The March of Time
by Friedel WeinertThe aim of this interdisciplinary study is to reconstruct the evolution of our changing conceptions of time in the light of scientific discoveries. It will adopt a new perspective and organize the material around three central themes, which run through our history of time reckoning: cosmology and regularity; stasis and flux; symmetry and asymmetry. It is the physical criteria that humans choose - relativistic effects and time-symmetric equations or dynamic-kinematic effects and asymmetric conditions - that establish our views on the nature of time. This book will defend a dynamic rather than a static view of time.
The Marginal Soils of Africa: Rethinking Uses, Management and Reclamation
by Adornis Dakarai Nciizah Ashira Roopnarain Busiswa Ndaba Mashapa Elvis MalobaneThis book addressed the pressing challenges of climate change, land scarcity, and food security, offering a comprehensive synthesis of research on using, managing, and reclaiming marginal lands in Africa. Unfavourable climatic conditions and rapid population growth intensify competition for land, putting pressure on traditional agricultural soils thus necessitating a transition towards underutilized marginal lands. Reclaiming these damaged and undervalued areas through various technologies presents a promising path not only to food independence but also to second-generation biofuel feedstock production, utilizing excess biomass from these revived lands. While recent years have seen increased focus on restoring degraded lands, a crucial gap remains i.e. a unified knowledge base detailing the efficacy of various reclamation technologies. This book fills that void, empowering farmers and policymakers with the insights they need to make informed decisions, mobilize resources effectively, and ultimately help Africa meet its projected 60% food demand increase.
The Marine Microbial Food Web: Competition and Defence as Shaping Forces from Ecosystem to Genes
by Tron Frede ThingstadAn authoritative and up-to-date exploration of how the competition-defence trade-off has shaped the marine microbial food web In The Marine Microbial Food Web: Competition and Defence as Shaping Forces from Ecosystem to Genes, distinguished researcher Tron Frede Thingstad delivers an insightful and practical discussion of the microbial portion of the ocean’s food web. The author describes how specific factors, including evolution, biodiversity, organism life strategies, genome organization, biogeochemistry, food web structure, and population dynamics, can be understood as the consequences of the balance between competition and defence. Using modular idealized mathematical models developed from classical Lotka-Volterra formulations, the book describes models that explain the balance between production and consumption of organic material in the photic zone and the potential for export to the ocean’s interior. It also explains how the models are relevant to contemporary climate change and a variety of other modern applications. Readers will also find: A thorough explanation of why the pathogenicity of many “L-strategists” probably originated as coincidental evolution from originally evolved mechanisms for predator defenceComprehensive explorations of the role of the marine microbial food web in ocean biogeochemistry and productionPractical discussions of simple mathematical models of competition, defence, trade-off, and fitnessFulsome treatments of a wide range of organization levels, including individual cells and larger communities of organisms Perfect for researchers, students, and instructors of marine ecology, marine microbiology, and microbial oceanography, The Marine Microbial Food Web will also prove invaluable to limnologists, oceanographers, and students with an interest in applied mathematics.

The Market in Birds: Commercial Hunting, Conservation, and the Origins of Wildlife Consumerism, 1850–1920
by Andrea L. SmalleyA fascinating look at how a commercial market for birds in the late nineteenth century set the stage for conservation and its legislation.Between the end of the Civil War and the 1920s, the United States witnessed the creation, rapid expansion, and then disappearance of a commercial market for hunted wild animals. The bulk of commercial wildlife sales in the last part of the nineteenth century were of wildfowl, who were prized not only for their eggs and meat but also for their beautiful feathers. Wild birds were brought to cities in those years to be sold as food for customers' tables, decorations for ladies' hats, treasured pets, and specimens for collectors' cabinets. Though relatively short-lived, this market in birds was broadly influential, its rise and fall coinciding with the birth of the Progressive Era conservation movement. In The Market in Birds, historian Andrea L. Smalley and wildlife biologist Henry M. Reeves illuminate this crucial chapter in American environmental history. Touching on ecology, economics, law, and culture, the authors reveal how commercial hunting set the terms for wildlife conservation and the first federal wildlife legislation at the turn of the twentieth century. Smalley and Reeves delve into the ground-level interactions among market hunters, game dealers, consumers, sportsmen, conservationists, and the wild birds they all wanted. Ultimately, they argue, wildfowl commercialization represented a revolutionary shift in wildlife use, turning what had been a mostly limited, local, and seasonal trade into an interstate industrial-capitalist enterprise. In the process, it provoked a critical public debate over the value of wildlife in a modern consumer culture. By the turn of the twentieth century, the authors reveal, it was clear that wild bird populations were declining precipitously all over North America. The looming possibility of a future without birds sparked intense debate nationwide and eventually culminated in the 1918 Migratory Bird Treaty Act. Scholars, environmentalists, wildlife professionals, and anyone concerned about wildlife will find this new perspective on conservation history enlightening reading.
The Market in Mind: How Financialization Is Shaping Neuroscience, Translational Medicine, and Innovation in Biotechnology (The\mit Press Ser.)
by Mark Dennis RobinsonA critical examination of translational medicine, when private risk is transferred to the public sector and university research teams become tech startups for global investors.A global shift has secretly transformed science and medicine. Starting in 2003, biomedical research in the West has been reshaped by the emergence of translational science and medicine—the idea that the aim of research is to translate findings as quickly as possible into medical products. In The Market in Mind, Mark Dennis Robinson charts this shift, arguing that the new research paradigm has turned university research teams into small biotechnology startups and their industry partners into early-stage investment firms. There is also a larger, surprising consequence from this shift: according to Robinson, translational science and medicine enable biopharmaceutical firms, as part of a broader financial strategy, to outsource the riskiest parts of research to nonprofit universities. Robinson examines the implications of this new configuration. What happens, for example, when universities absorb unknown levels of risk? Robinson argues that in the years since the global financial crisis translational science and medicine has brought about “the financialization of health.”Robinson explores such topics as shareholder anxiety and industry retreat from Alzheimer's and depression research; how laboratory research is understood as health innovation even when there is no product; the emergence of investor networking events as crucial for viewing science in a market context; and the place of patients in research decisions. Although translational medicine justifies itself by the goal of relieving patients' suffering, Robinson finds patients' voices largely marginalized in translational neuroscience.

The Marmoset Brain in Stereotaxic Coordinates
by Xavier Palazzi Nicole BordierLaboratory-bred common marmosets (Callithrix jacchus) have a natural lifespan in captivity in excess of 12 years, while their maximum longevity is more than 16 years. Due to its small size, its relatively easy adaptation to laboratory conditions, and neuroanatomical similarities with human species, this animal is considered to represent a convenient primate model for neurosciences and drug development. The Marmoset Brain in Stereotaxic Coordinates provides a comprehensive guide for those - both researchers and undergraduates - who are interested in the marmoset brain, tissue target characterization and comparative anatomy. The nomenclature and atlas presentation were inspired from existing reference brain atlases in other species, and the high quality of illustrations was achieved thanks to automated whole slide scanning.
The Marriage of Sense and Soul: Integrating Science and Religion
by Ken WilberThere is arguably no more critical and pressing topic than the relation of science and religion in the modern world. Science has given us the methods for discovering truth, while religion remains the single greatest force for generating meaning. Yet the two are seen as mutually exclusive, with wrenching consequences for humanity. In The Marriage of Sense and Soul, one of today's most important philosophers brilliantly articulates how we might begin to think about science and religion in ways that allow for their reconciliation and union, on terms that will be acceptable to both camps. Ken Wilber is widely acclaimed as the foremost thinker in integrating Western psychology and the Eastern spiritual traditions. His many books have reached across disciplines and synthesized the teachings of religion, psychology, physics, mysticism, sociology, and anthropology, earning him a devoted international following. The Marriage of Sense and Soul is his most accessible work yet, aimed at guiding a general audience to the mutual accord between the spiritual, subjective world of ancient wisdom and the objective, empirical world of modern knowledge. Wilber clearly and succinctly explores the schism between science and religion, and the impact of this "philosophical Cold War" on the fate of humanity. He systematically reviews previous attempts at integration, explaining why romantic, idealistic, and postmodern theories failed. And he demonstrates how science is compatible with certain deep features common to all of the world's major religious traditions. In pointing the way to a union between truth and meaning, Ken Wilber has created an elegant and accessible book that is breathtaking in its scope.From the Hardcover edition.

The Martians: Evidence of Life on the Red Planet
by Nick Redfern“This provocative and exciting book . . . makes a startling case for there being life on Mars.” —Whitley Strieber, #1 New York Times–bestselling author of CommunionThe Martians is an in-depth study of the theory that Mars was once a world that teemed with life. Perhaps, even, life not too dissimilar to ours. Incredibly, the Martians may still be there. Alive. The questions that this book asks and answers include the following:• What kind of society did the Martians have?• What caused their world to become harsh and desert-like?• Did global warming or nuclear war ensure the extinction of the Martians?• Are Martian artifacts strewn about the surface, just waiting to be found by the likes of NASA?• Has NASA already found such evidence, but chosen to withhold such monumental finds from the public and the media?• Could some form of the Martians still exist, deeply below the surface of the planet, in secure installations that allow them to ensure their civilization continues?• What do we know about the Martian environment, its atmosphere, and its landscape?The Martians explores the CIA’s top-secret search for the Martians, multiple photos of strange anomalies, and the latest revelations about the environment and water on Mars. And most tantalizing of all: Did an ailing Martian race come to Earth in past eons and were they confused with gods? The questions concerning life on Mars—then and now—are many. The answers are astounding.

The Marvelous Learning Animal
by Arthur W. StaatsWhat makes us human? In recent decades, researchers have focused on innate tendencies and inherited traits as explanations for human behavior, especially in light of groundbreaking human genome research. The author thinks this trend is misleading. As he shows in great detail in this engaging, thought-provoking, and highly informative book, what makes our species unique is our marvelous ability to learn, which is an ability that no other primate possesses. In his exploration of human progress, the author reveals that the immensity of human learning has not been fully understood or examined. Evolution has endowed us with extremely versatile bodies and a brain comprised of one hundred billion neurons, which makes us especially suited for a wide range of sophisticated learning. Already in childhood, human beings begin learning complex repertoires--language, sports, value systems, music, science, rules of behavior, and many other aspects of culture. These repertoires build on one another in special ways, and our brains develop in response to the learning experiences we receive from those around us and from what we read and hear and see. When humans gather in society, the cumulative effect of building learning upon learning is enormous.The author presents a new way of understanding humanness--in the behavioral nature of the human body, in the unique human way of learning, in child development, in personality, and in abnormal behavior. With all this, and his years of basic and applied research, he develops a new theory of human evolution and a new vision of the human being. This book offers up a unified concept that not only provides new ways of understanding human behavior and solving human problems but also lays the foundations for opening new areas of science.

The Maryland Amphibian and Reptile Atlas
by Heather R. Cunningham and Nathan H. NazdrowiczThe definitive resource for finding, identifying, and conserving Maryland’s amphibians and reptiles.Naturalists, herpetologists, and ecologists alike agree that tracking herpetofauna is a challenging undertaking. Scientists are concerned about the decline of once-familiar species, but evidence has often been too anecdotal to support firm conclusions. To better understand the distribution of amphibians and reptiles in Maryland and forecast species' futures in a time of accelerated environmental threats, conducting a comprehensive statewide survey updating 1970s-era distribution maps seemed ideal. However, this endeavor was of an impossibly ambitious scope for scientists alone to tackle. Enter the Maryland Amphibian and Reptile Atlas project, comprising nearly a thousand dedicated citizen scientists who discovered and recorded the locations of herpetofauna throughout every corner of Maryland. In The Maryland Amphibian and Reptile Atlas, Heather R. Cunningham and Nathan H. Nazdrowicz present the findings of this massive undertaking. This definitive guide combines nearly 160 comprehensive new herpetological maps with historical distribution maps and in-depth species accounts. Color photos illustrate the natural history of the 89 species of frogs, salamanders, turtles, snakes, and lizards that call the state home. Essays discuss historical studies, the effects of Maryland's current climate, geology, and habitat diversity—and the myriad conservation issues these animals face. This richly detailed book represents a triumph of citizen science and the culmination of an intensive research partnership. It will appeal to both amateurs and professionals interested in herpetology, natural history, or ecology, as well as those with a special interest in Maryland's biodiversity.
The Mask of Benevolence: Disabling the Deaf Community
by Harlan LaneA look at the gulf that separates the deaf minority from the hearing world, this book sheds light on the mistreatment of the deaf community by a hearing establishment that resists understanding and awareness. Critically acclaimed as a breakthrough when it was first published in 1992, this new edition includes information on the science and ethics of childhood cochlear implants. An indictment of the ways in which experts in the scientific, medical, and educational establishment purport to serve the deaf, this book describes how they, in fact, do them great harm.
The Mask of Command
by John KeeganJohn Keegan’s brilliant look at the meaning of leadership In The Mask of Command, John Keegan asks us to consider questions that are seldom asked: What is the definition of leadership? What makes a great military leader? Why is it that men, indeed sometimes entire nations, follow a single leader, often to victory, but with equal dedication also to defeat? Dozens of names come to mind...Napoleon, Lee, Charlemagne, Hannibal, Castro, Hussein. From a wide array, Keegan chooses four commanders who profoundly influenced the course of history: Alexander the Great, the Duke of Wellington, Ulysses S. Grant, and Adolph Hitler. All powerful leaders, each cast in a different mold, each with diverse results. The Mask of Command is a companion volume to John Keegan's classic study of the individual soldier, The Face of Battle: together they form a masterpiece of military and human history.

The Mast Cell: A Multifunctional Effector Cell
by Domenico RibattiMast cells (MC) are phylogenetically old cells which are distributed throughout the human organism. MC are found in almost all of the major organs and tissues of the body, particularly in association with connective tissue structures such as blood vessels, lymphatic vessels and nerves, and in proximity to surfaces that interface the external environment, such as those of the respiratory and gastrointestinal system and the skin. This selective accumulation at tissue sites where foreign material attempts to invade the host suggests that MC are among the first cells to initiate defensive mechanisms. MC have long been recognized as key cells of type I hypersensitivity reactions. Several lines of evidence, however, indicate that they not only express critical effector functions in classic IgE-associated allergic disorders, but also play important roles in host defense against parasites, bacteria and perhaps even viruses. Indeed, it is now clear that MC can contribute to host defense in the context of either acquired or innate immune responses through the release of a myriad of pro-inflammatory and immunoregulatory molecules and the expression of a wide spectrum of surface receptors for cytokines and chemokines. Moreover, there is growing evidence that MC exert distinct non-immunological functions, playing a relevant role in tissue homeostasis, remodeling and fibrosis as well as in the processes of tissue angiogenesis.
The Master Algorithm: How the Quest for the Ultimate Learning Machine Will Remake Our World
by Pedro DomingosAlgorithms increasingly run our lives. They find books, movies, jobs, and dates for us, manage our investments, and discover new drugs. More and more, these algorithms work by learning from the trails of data we leave in our newly digital world. Like curious children, they observe us, imitate, and experiment. And in the world’s top research labs and universities, the race is on to invent the ultimate learning algorithm: one capable of discovering any knowledge from data, and doing anything we want, before we even ask. Machine learning is the automation of discovery--the scientific method on steroids--that enables intelligent robots and computers to program themselves. No field of science today is more important yet more shrouded in mystery. Pedro Domingos, one of the field’s leading lights, lifts the veil for the first time to give us a peek inside the learning machines that power Google, Amazon, and your smartphone. He charts a course through machine learning’s five major schools of thought, showing how they turn ideas from neuroscience, evolution, psychology, physics, and statistics into algorithms ready to serve you. Step by step, he assembles a blueprint for the future universal learner--the Master Algorithm--and discusses what it means for you, and for the future of business, science, and society. If data-ism is today’s rising philosophy, this book will be its bible. The quest for universal learning is one of the most significant, fascinating, and revolutionary intellectual developments of all time. A groundbreaking book, The Master Algorithm is the essential guide for anyone and everyone wanting to understand not just how the revolution will happen, but how to be at its forefront.
