    It is within the realm of possibility that their work may usher in a change in global economics as profound as the Industrial Revolution. As may be expected, press reports dealing with asteroid mining have been numerous, ranging in scope from short and breezy to broad and serious, and in quality from accurate to impressionistic to simply uninformed. There is good reason to be curious about what may be the biggest game-changer in human economic history. And there is good reason to look closely at the underlying science and engineering that form the foundation of this work.

    Those principles included modern theories of atomic and molecular structure, quantum mechanics, statistical mechanics and thermodynamics. In addition, Dr. Pauling attempted to correlate the theories with descriptive chemistry, the observed properties of substances, to introduce the student to the multitude of chemical substances and their properties.In this extensively revised and updated third edition, the Nobel prizewinning author maintains an excellent balance between theoretical and descriptive material, although the amount of descriptive chemistry has been decreased somewhat, and the presentation of the subject, especially in relation to the nonmetals, has been revised in such a way as to permit greater correlation with the electronic structure of atoms, especially electronegativity. The principles of quantum mechanics are discussed on the basis of the de Broglie wavelength of the electron. The quantized energy levels of a particle in a box are derived by means of a simple assumption about the relation of the de Broglie waves to the walls of the box. No attempt is made to solve the Schrödinger wave equation for other systems, but the wave functions of hydrogen-like electrons are presented and discussed in some detail, and the quantum states for other systems are also covered. Statistical mechanics is introduced before thermodynamics, and the discussion of thermodynamics is based on it. This arrangement reflects the author's belief that beginning students can understand statistical mechanics better than chemical thermodynamics. Aimed at first-year college students who plan to major in chemistry or closely related fields, the book is written in a logical, clear and understandable style. In addition, many excellent figures are included, along with numerous problems and 75 pages of appendixes covering such topics as symmetry of molecules and crystals, hybrid bond orbitals, and magnetic properties of substances.

    Featuring thirty-nine readings divided into four parts--Value Theory, Normative Ethics, Metaethics, and Moral Problems--it introduces students to ethical theory and a wide range of moral issues. The essays include selections from such historically influential philosophers as Aristotle, Hume, Kant, and Mill alongside work by contemporary philosophers like Philippa Foot, Robert Nozick, Peter Singer, and Judith Jarvis Thomson. Detailed section and reading introductions provide helpful contextual information. Designed as a companion reader to Russ Shafer-Landau's textbook, The Fundamentals of Ethics, The Ethical Life is also comprehensive enough to be used on its own. The book is enhanced by an Instructor's Manual and Testbank on CD and a Companion Website for students and instructors.

    An engineer by training, Bernstein pioneered blood glucose self-monitoring and the tight control of blood sugar that is now accepted as the standard treatment of diabetes.

    In this Very Short Introduction, engineer David Muir Wood turns a spotlight on a field that we often take for granted. He sheds light on the nature and importance of civil engineering in the history of civilization and urbanization, outlines its many accomplishments in the modern era, and points to the hurdles that civil engineering will face in the future. Beginning with the task of creating a settlement on a deserted island, Muir Wood sets out the problems that civil engineers face every day, highlighting the social and environmental challenges as well as the grasp of science and technology needed to craft buildings, bridges, tunnels, houses, and areas of recreation. The author also profiles the lives of some of the major civil engineers, such as Isambard Kingdom Brunel, the acclaimed builder of steamships, railways, and tunnels, and Sir Joseph Bazalgette, whose sewer system in central London was instrumental in relieving the city from cholera epidemics. Finally, Muir Wood considers the growing difficulty of managing our water and energy supplies, and he looks at the engineering profession's increased sensitivity to building and the environment.

    The book covers the syllabus for Engineering chemistry course offered to first year B.E/B.Tech students of various India University

    It considers the evolving economy and society - the basic facts of life for the majority of Europe's people. It shows how the religious and intellectual unity of western culture fragmented anddissolved under the impact of new ideas. It also examines politics to consider the emergence of modern attitudes and techniques in governing.

    Emphasis is placed upon the theoretical basis of each type of instrument, its optimal area of application, its sensitivity, its precision, and its limitations. The text also introduces students to elementary integrated circuitry, microprocessors and computers, and treatment of analytical data.

    

    Penned by award-winning science writer John Emsley, Nature's Building Blocks explains the what, why and wherefore of the chemical elements. Arranged alphabetically, from Actinium to Zirconium, it is a complete guide to all 115 of those that are currently known, with more extensive coverage of those elements we encounter in our everyday life. The entry on each element reveals where it came from, what role it may have in the human body, and the foods that contain it. There are also sections on its discovery, its part in human health or illness, the uses and misuses to which it is put, and its environmental role. Readers discover that the Earth consists of around 90 elements, some of which are abundant, such as the silicon and oxygen of rocks and soils, while some are so rare that they make gold seem cheap. Our own bodies contain about 30 elements, some in abundance, some in trace amounts; some vital to our health, and some that are positively harmful. A list of the main scientific data, and outline properties, are given for every element and each section ends with an Element of Surprise, which highlights some unexpected way in which each element influences our everyday life. Both a reliable reference source and a high browsable account of the elements, Nature's Building Blocks offers a pleasurable tour of the very essence of our material world.

    Now she introduces readers to another part of that world as she recounts the life of a madam, Peach, who runs a successful mid-level escort service in Boston. Told from Peach's point of view, Madam looks at all different facets of this life--from the need to run an efficient business to how she explains her career choice to others. Raised in the South, Peach came to Boston for college, but found herself sidetracked early on, her talent for business vying with her aspirations to literature. Finding herself working as a receptionist in a suburban brothel. she soon realized that she could run a similar business much more effectively--and with more kindness. And for some years she does, living at night, going out to clubs and restaurants... until she discovers that she wants more from life. Now married and the mother of children, her daytime life seems at odds with the business that she runs--or does it? Here again is a way for readers to understand an invisible world and an invisible life and to put faces on the faceless people of the night. Like Callgirl, Madam's message is that they are not so different from the people who live next door to you. They may, in fact, even be your neighbors.

    The 25 chapters are written by experts from around the world and provide extensive coverage of history, theories, institutions and actors, policies, and issues and debates.

     Drug pricing is a staple of every news cycle and political debate. And while we’ve struggled for decades to agree on solutions that serve all patients without jeopardizing the invention of new medicines, many Americans suffer because they can’t afford the drugs they need. Do we really have to choose between affordability and innovation? In The Great American Drug Deal, scientist and industry expert Peter Kolchinsky answers this question with a decisive No. The pharmaceutical industry’s commitment to creating new lifesaving drugs destined to become inexpensive generics can be balanced by the healthcare system’s commitment to making those drugs affordable for all patients—a Biotech Social Contract. Through deep research and compelling stories of breakthroughs and breakdowns, Kolchinsky presents solutions for striking a balance that are bold yet realistic and tackle today’s most pressing questions, including: Why doesn’t insurance make drugs affordable? How can we prevent price-jacking of older drugs? Why are drugs more expensive in America than elsewhere? How can we guarantee that all medicines eventually go generic so they are only temporarily expensive? What systemic failures led to the opioid crisis, and how can we prevent the next one? The Great American Drug Deal offers clear-eyed scrutiny of all players in the industry and examines vital ideas for closing loopholes, encouraging investment, dealing with bad actors, and educating consumers. It’s time we resolve to support patients and fuel discoveries that ease suffering now and for generations to come.

    Everyone everywhere now carries a dizzying array of chemical contaminants, the by-products of modern industry and innovation that contribute to a host of developmental deficits and health problems in ways just now being understood. These toxic substances, unknown to our grandparents, accumulate in our fat, bones, blood, and organs as a consequence of womb-to-tomb exposure to industrial substances as common as the products that contain them. Almost everything we encounter?from soap to soup cans and computers to clothing?contributes to a chemical load unique to each of us. Scientists studying the phenomenon refer to it as ?chemical body burden,? and in The Body Toxic, the investigative journalist Nena Baker explores the many factors that have given rise to this condition?from manufacturing breakthroughs to policy decisions to political pressure to the demands of popular culture. While chemical advances have helped raise our standard of living, making our lives easier and safer in many ways, there are costs to these conveniences that chemical companies would rather consumers never knew about. Baker draws back the curtain on this untold impact and assesses where we go from here.
