This elegant book presents current evidence on the organization of the mammalian cerebral cortex. The focus on synapses and their function provides the basis for understanding how this critical part of the brain could work. Dr. White and his colleague Dr. Keller have collated an impressive mass of material. This makes the crucial information accessible and coherent. Dr. White pioneered an area of investigation that to most others, and occasionally to himself, seemed a bottomless pit of painstaking at tention to detail for the identification and enumeration of cortical syn apses. I do not recall that he or anyone else suspected, when he began to publish his now classic papers, that the work would be central to an accelerating convergence of information and ideas from neurobiology and computer science, especially artificial intelligence (AI) (Rumelhart and McClelland, 1986). The brain is the principal organ responsible for the adaptive capacities of animals. What has impressed students of biology, of medicine, and, to an extent, of philosophy is the correlation between the prominence of the cerebral cortex and the adaptive "complexity" of a particular spe cies. Most agree that the cortex is what sets Homo sapiens apart from other species quantitatively and qualitatively (Rakic, 1988). This is summarized in the first chapter."
The doctrine of computer life is not congenial to many people. Often they have not thought in any depth about the idea, and it necessarily disturbs their psychological and intellectual frame of reference: it forces a reappraisal of what it is to be alive, what it is to be human, and whether there are profound, yet un expected, implications in the development of modern com puters. There is abundant evidence to suggest that we are wit nessing the emergence of a vast new family of life-forms on earth, organisms that are not based on the familiar metabolic chemistries yet whose manifest 'life credentials' are accumulating year by year. It is a mistake to regard biology as a closed science, with arbitrarily limited categories; and we should agree with Jacob (1974) who observed that 'Contrary to what is imagined, biology is not a unified science'. Biology is essentially concerned with living things, and we should be reluctant to assume that at anyone time our concept and understanding of life are complete and incapable of further refinement. And it seems clear that much of the continuing refinement of biological categories will be stimulated by advances in systems theory, and in particular by those advances that relate to the rapidly expanding world of computing and robotics. We should also remember what Pant in (1968) said in a different context: 'the biological sciences are unrestricted . . . and their investigator must be prepared to follow their problems into any other science whatsoever."
The authors, leading representatives of Russian space research and industry, show the results and future prospects of astronautics at the start of the third millennium. The focus is on the development of astronautics in Russia in the new historical and economic conditions. The text spotlights the basic trends in space related issues before moving on to describe the possibilities of the wide use of space technologies and its numerous applications such as navigation and communication, space manufacturing, and space biotechnology. The book contains a large amount of facts described in a way understandable without specialist knowledge. The text is accompanied by many photographs, charts and diagrams, mostly in color.
Why in the world are we paying for all this "basic" research? The answer to this question becomes clear in this romp through the "seemingly useless" world of pure science, where one thing leads to another in ways that result in major scientific advancements. With a novelistic style, C. Renee James reveals how obscure studies of natural phenomena--including curved space-time, poisonous cone snails, exploding black holes, and the precise chemical makeup of the sun--led unexpectedly to WiFi, GPS, genetic sequencing, pain medications, and cancer treatments. "Science Unshackled" brings both science and scientists to life and shows how simple curiosity can result in life-changing breakthroughs. Scientists engaged in basic research, funded in large part by governments around the globe and throughout the centuries, never know when exploring small questions will have big impacts. But, by following the scientific method, disciplined inquiry can lead to wondrous and practical discoveries that benefit all of us in the end. The next time someone asks you why "the government" wastes its money on weird research, recall the intriguing stories James has told and tell them the answer.
J. Robert Oppenheimer, a leading physicist in the Manhattan Project, recognized that scientific inquiry and discovery could no longer be separated from their effect on political decision-making, social responsibility, and human endeavor in general. He openly addressed issues of common concern and as a scientist accepted the responsibility brought about by nuclear physics. This collection of essays and speeches, only a few of which have been previously published, presents an extraordinary thinker and scientist as well as a compassionate human being. No issue is too small or too large if it is in some way connected to the emergence of a weapon as terrible and powerful as the atom bomb. Oppenheimer discusses the shift in scientific awareness and its impact on education, the question of openness in a society forced to keep secrets, the conflict between individual concerns and public and political necessity, the future of science and its effects on future politics---in short, the common and uncommon sense we find in our modern day reality. Uncommon Sense presents a responsible scientist and a concerned man who foresaw the problems the discovery of fission would create. And we should no neglect to read between the lines: The peak of Oppenheimer s career coincided with the McCarthy era, the repercussions of which strongly affected his personal and professional life. The themes of openness and freedom becomes, therefore, recurring concerns in this collection of essays and speeches."
Some fifty years ago as a cub reporter, Barbree caught space fever the night that Sputnik passed over Albany, Georgia. On a double date where the couples actually did some star gazing, Barbree recognized that exploring space would become one of the most important stories of the century. Convinced that one day astronauts would walk on the moon, Barbree moved to the then sleepy ocean-side community of Cocoa Beach, right outside Cape Canaveral, and began reporting on rockets that soared, exploded, and fizzled. In the decades to come he witnessed a parade of history as space pioneers, hucksters, groupies and politicians participated in the greatest show of technology the world had ever seen. In "Live from Cape Canaveral", Barbree offers his unique perspective on the space program. Warm and perceptive, he reminds us just how thrilling the great moments of the space race were and why America fell in love with its heroic, sometimes larger-than-life astronauts.
How math holds the keys to improving one's health, wealth, and love life What's the best diet for overall health and weight management? How can we change our finances to retire earlier? How can we maximize our chances of finding our soul mate? In The Calculus of Happiness, Oscar Fernandez shows us that math yields powerful insights into health, wealth, and love. Using only high-school-level math (precalculus with a dash of calculus), Fernandez guides us through several of the surprising results, including an easy rule of thumb for choosing foods that lower our risk for developing diabetes (and that help us lose weight too), simple "all-weather" investment portfolios with great returns, and math-backed strategies for achieving financial independence and searching for our soul mate. Moreover, the important formulas are linked to a dozen free online interactive calculators on the book's website, allowing one to personalize the equations. Fernandez uses everyday experiences--such as visiting a coffee shop--to provide context for his mathematical insights, making the math discussed more accessible, real-world, and relevant to our daily lives. Every chapter ends with a summary of essential lessons and takeaways, and for advanced math fans, Fernandez includes the mathematical derivations in the appendices. A nutrition, personal finance, and relationship how-to guide all in one, The Calculus of Happiness invites you to discover how empowering mathematics can be.
Veteran NPR(R) science reporter and award-winning radio and TV journalist Ira Flatow's enthusiasm for all things scientific has made him a beloved on-air correspondent.

A book that challenges common misconceptions about the nature of intelligence Satoshi Kanazawa's "Why Beautiful People Have More Daughters" (written with Alan S. Miller) was hailed by the "Los Angeles Times" as ""a rollicking bit of pop science that turns the lens of evolutionary psychology on issues of the day."" That book answered such burning questions as why women tend to lust after males who already have mates and why newborns look more like Dad than Mom. Now Kanazawa tackles the nature of intelligence: what it is, what it does, what it is good for (if anything). Highly entertaining, smart (dare we say intelligent?), and daringly contrarian, "The Intelligence Paradox" will provide a deeper understanding of what intelligence is, and what it means for us in our lives.Asks why more intelligent individuals are not better (and are, in fact, often worse) than less intelligent individuals in solving some of the most important problems in life--such as finding a mate, raising children, and making friends Discusses why liberals are more intelligent than conservatives, why atheists are more intelligent than the religious, why more intelligent men value monogamy, why night owls are more intelligent than morning larks, and why homosexuals are more intelligent than heterosexuals Explores how the purpose for which general intelligence evolved--solving evolutionarily novel problems--allows us to explain why intelligent people have the particular values and preferences they have Challenging common misconceptions about the nature of intelligence, this book offers surprising insights into the cutting-edge of science at the intersection of evolutionary psychology and intelligence research.
Modern forest products research had its start hardly fifty years ago. Today we are in a position to apply the title "wood science" to the field of wood technology that is based on scientific investigation, theoretical as well as experimental. It is this research that fosters new uses for wood as a raw material and that creates the foundation for new industries for the manufacture of wood-base materials such as plywood, laminated products, particle and fiber board and sand wich construction. Wood technology in its broadest sense combines the disciplines of wood anatomy, biology, chemistry, physics and mechanical technology. It is through this interdisciplinary approach that progress has been made in wood seasoning, wood preservation methods, wood machining, surfacing and gluing, and in the many other processes applied in its utilization. In 1936 the senior author published a book entitled, "Technologie des Holzes," which was a first approach to a universal reference book on wood technology. The first edition of Volume I of the Textbook of Wood Technology, co-authored by H. P. BROWN, A. J. P AN SHIN, and C. C. FORSAITH, was published in 1948. An indication of the rapid development of this field can be gained from the fact that the second edition of "Technologie des Holzes und der Holzwerkstoffe," completely revised, was needed by 1951. It contains 2233 pages compared with the 764 pages of the 1936 edition."
In the next decade, NASA, by itself and in collaboration with the
European Space Agency, is planning a minimum of four separate
missions to Mars. Clearly, exciting times are ahead for Mars
exploration. This is an insider's look into the amazing projects
now being developed here and abroad to visit the legendary red
planet. Drawing on his contacts at NASA and the Jet Propulsion
Laboratory, the author provides stunning insights into the history
of Mars exploration and the difficulties and dangers of traveling
there.
Every person on our home planet is affected by a worldwide deluge of man-made chemicals and pollutants - most of which have never been tested for safety. Our chemical emissions are six times larger than our total greenhouse gas emissions. They are in our food, our water, the air we breathe, our homes and workplaces, the things we use each day. This universal poisoning affects our minds, our bodies, our genes, our grandkids, and all life on Earth. Julian Cribb describes the full scale of the chemical catastrophe we have unleashed. He proposes a new Human Right - not to be poisoned. He maps an empowering and hopeful way forward: to rid our planet of these toxins and return Earth to the clean, healthy condition which our forebears enjoyed, and our grandchildren should too.
This book explains how society will face an energy crisis in the coming decades owing to increasing scarcity of fossil fuels and climate change impacts. It carefully explores this coming crisis and concisely examines all of the major technologies related to energy production (fossil fuels, renewables, and nuclear) and their impacts on our society and environment. The author argues that it is wrong to pit alternatives to fossil fuels against each other and proposes that nuclear energy, although by no means free of problems, can be a viable source of reliable and carbon-free electricity. He concludes by calling for a diversified and rational mix of electricity generation in order to mitigate the effects of the energy crisis. Throughout, the book is spiced with science, history, and anecdotes in a way that ensures rewarding reading without loss of rigor.
Written for mathematicians, engineers, and researchers in experimental science, as well as anyone interested in fractals, this book explains the geometrical and analytical properties of trajectories, aggregate contours, geographical coastlines, profiles of rough surfaces, and other curves of finite and fractal length. The approach is by way of precise definitions from which properties are deduced and applications and computational methods are derived. Written without the traditional heavy symbolism of mathematics texts, this book requires two years of calculus while also containing material appropriate for graduate coursework in curve analysis and/or fractal dimension.
This is a compelling exploration of how our understanding of evolution is key to the future of our planet. When Charles Darwin started writing his work On "Origin of Species", he could hardly have envisioned how much we would discover about the origin of life over the next 150 years. Today's evidence points to an inescapable and simple conclusion - we evolved and we are still evolving. This persuasive and elegant book, argues that understanding evolution has never mattered more in human history. It explains in detail how health, food production, and human impact on the environment are dependent on our knowledge of evolution.
We not only live in the air, we live because of it. At ground level air transforms miraculously; it wraps our planet in a blanket of warmth, while the outer layer of our atmosphere soaks up violent flares from the sun. In this fascinating celebration of the Earth's fragile atmosphere, Gabrielle Walker traces a journey of groundbreaking scientific discovery from the first experiments in the Renaissance to recent findings in space.

Vestibular physiology has acquired new interest in the past few years. The development of fast aircraft, beginning during the Second World War and continuing through modern supersonic jets and space travel, has increased dramatically the acceleration range to which man is subjected, from prolonged weightlessness to several gs. The labyrinth measures all kinds of acceleration, including gravity. and therefore has taken on particular impor tance in the study of human health in the Space Age. It is understandable. then, that NASA sponsored the Symposium on Vestibular Function and Morphology. a satellite of the Eighth Annual Meeting of the Society of Neuroscience. held October 30-November 1. 1978, at the University of Pittsburgh, which also supported the symposium. The present volume was developed from papers originally presented there. My strategy in editing this book has been to focus upon the vestibular end organ and its direct connections. both peripheral and central, in order to as sure a coherent discussion of the basics of vestibular function, structure, and ultrastructure. Fortunately, it was possible to secure the contributions of a number of outstanding investigators from both the United States and abroad, including functionally oriented morphologists. ultrastructuralists, biophysicists, and vestibular physiologists. The result is a comprehensive discussion of the main mechanisms of the labyrinth: the transduction pro cess at the receptor level, in the semicircular canals, and in the utricular and saccular maculae; the information transfer through neuronal pathways to the nuclei and the cerebellum; and the general organization of the system."
Human beings evolved in a tribal environment. Over the millennia,
our brains have become adept at fostering social networks that are
the basis of group cohesion, from the primary family unit to the
extended associations of clans, villages, cities, and nations. This
essential social component of our behavior gave the human species
distinct survival advantages in coping with the challenges of an
often-hostile environment.
Why does kicking the TV work? What can the US military learn from the lowly bacterium? Why are the instruction manuals for cell phones incomprehensible? How does a spark of a single virus trigger an epidemic that claims millions? In recent years, cutting-edge studies in fields such as economics, genetics, stock-market analysis and child development have hit on a startling new theory - 'simplexity'. To put it simply, simple things can be more complicated than they seem, and complex things more simple. The evidence is before our eyes: in your elaborate network of household plumbing actually run on a very basic mechanism, or the crystal paperweight on your desk, spectacular in its complexity. As simplexity moves from the research lab into popular consciousness it will challenge our models for modern living. You'll never unknowingly whack the TV again and you'll understand just how much it means to smile at your child. Popular science journalist Jeffrey Kluger adeptly translates cutting-edge theory into a high-octane history of everything, which will have you rethinking the rules of business and pleasure. From the micro to the macro, Simplexity is a startling reassessment of the building blocks of life and how they affect us all.
Southeast Asia constitutes one of the world's most extended rainforest regions. It is characterized by a high degree of biodiversity and contains a large variety of endemic species. Moreover, these forests provide a number of important and sin gular ecosystem services, like erosion protection and provision of high quality wa ter, which cannot be replaced by alternative ecosystems. However, various forms of encroachment, mostly those made by human interventions, seriously threaten the continuance of rainforests in this area. There is ample evidence that the rainforest resources, apart from large scale commercial logging, are exposed to danger particularly from its margin areas. These areas, which are characterized by intensive man-nature interaction, have been identified as extremely fragile systems. The dynamic equilibrium that bal ances human needs and interventions on the one hand, and natural regeneration capacity on the other, is at stake. The decrease of rainforest resources is, to a sub stantial degree, connected with the destabilization of these systems. Accordingly, the search for measures and processes, which prevent destabilization and promote stability is regarded as imperative. This refers to both the human and the natural part of the forest margin ecosystem."
Whether you are a student struggling to fulfill a math or science
requirement, or you are embarking on a career change that requires
a higher level of math competency, "A Mind for Numbers" offers the
tools you need to get a better grasp of that intimidating but
inescapable field. Engineering professor Barbara Oakley knows
firsthand how it feels to struggle with math. She flunked her way
through high school math and science courses, before enlisting in
the army immediately after graduation. When she saw how her lack of
mathematical and technical savvy severely limited her options--both
to rise in the military and to explore other careers--she returned
to school with a newfound determination to re-tool her brain to
master the very subjects that had given her so much trouble
throughout her entire life.
Air pollution has become the world's greatest environmental health risk, and science is only beginning to reveal its wide-ranging effects. Globally, 19,000 people die each day from air pollution, killing more than HIV/AIDS, tuberculosis, malaria and car accidents combined. What happened to the air we breathe? Sustainability journalist Tim Smedley has travelled the world to try and find the answer, visiting cities at the forefront of the fight against air pollution, including Delhi, Beijing, London and Paris. With insights from the scientists and politicians leading the battle against it, and people whose lives have been affected by it. Clearing the Air tells the full story of air pollution for the first time: what it is, which pollutants are harmful, where they come from and - most importantly - what we can do about them. Air pollution is a problem that can be solved. The stories uncovered on this journey show us how. Clearing the Air is essential reading for anyone who cares about the air they breathe. And this much becomes clear: in the fight against air pollution, we all have a part to play. The fightback has begun.
