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.

    It treats the subject as a coherent whole, complete with numerous logical connections, consequences, and an underlying structure and language. Employing an approach based on mechanism and reaction type, the book empasizes understanding ideas rather than merely memorizing facts. It shows students how to realistically draw molecules and mechanisms to reveal the fundamental chemistry.Using a fresh, accessible writing style as well as examples from everyday life, the authors explain the basics of organic chemistry carefully and thoroughly. A special focus on mechanism, orbitals, and stereochemistry helps students gain a solid comprehension of important factors common to all reactions. The book's innovative design enhances clarity and instruction with boxes that separate summary information and other material from the main text; a variety of colors that draw attention to items such as atoms, molecules, and orbitals; and figures that are drawn in red with significant parts emphasized in black. Early chapters feature carbonyl group reactions, and later chapters systematically develop the chemistry through discussions of spectroscopy, stereochemistry, and chemical reactions.Each chapter opens with a Connections box, divided into three columns:- Building on: Details material from previous chapters that relate to the current chapter- Arriving at: Provides a guide to the content of the chapter- Looking forward to: Previews later chapters, which develop and expand the current material

    He decried the internment of Japanese-Americans in World War Two, agitated against nuclear weapons, promoted vitamin C as a cure for the common cold and researched the idea of DNA.

    

    The atomic bombs that came out of it brought an end to the war in the Pacific, but at a heavy loss of life in Japan and the opening of a Pandora's box that has tested international relations.This book traces the history of the Manhattan Project, from the first glimmerings of the possibility of such a catastrophic weapon to the aftermath of the bombings of Hiroshima and Nagasaki. It profiles the architects of the bomb and how they tried to reconcile their personal feelings with their ambition as scientists. It looks at the role of the politicians and it includes first-hand accounts of those who experienced the effects of the bombings.

    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.

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

    Now, in his first cookbook, Ming shares the technique and philosophy behind his exciting cross-cultural fare.        The key, Ming explains, is retaining a healthy respect for the traditions of each cuisine so that diverse elements can be combined in a harmonious way. His trademark Foie Gras and Morel Shu Mai, for example, elevates a traditional yet simple Asian preparation with a luxuriously sophisticated Western ingredient and transforms a humble dish into truly elegant fare. Prosciutto and Asian Pear Maki is a playful reinterpretation of a Japanese favorite, while Classic Roast Chicken with Sticky Rice Stuffing gives the holiday staple a savory new spin. The result is food that's inventive yet not trendy, complex in flavor but surprisingly easy to prepare.        In chapters devoted to Soups; Dim Sum (irresistible starters and bite-sized party fare); Rice and Noodles; Seafood; Birds; Meat; Sides; Oils, Dips and Seasonings; and Desserts, Ming proves again and again how delicious the coming together of East and West can be: Gingered Beef with Leeks and Asparagus, Hoisin-Marinated Chicken with Napa Slaw, Asian Gazpacho with Cilantro-Jicama Cream, and Wok-Flashed Salt and Pepper Shrimp are all quick and straightforward preparations that provide big flavors in every bite. And when it's time to pull out all the stops, a chapter dedicated to Over-the-Top recipes will guide home cooks through an array of showstopping dishes that dazzle with innovative techniques and presentations. Beverage suggestions accompany each recipe to complete the dining experience.         Filled with Ming's tips for working with unfamiliar ingredients and preparations, Blue Ginger is an outstanding introduction to the pleasures of East-West cooking.

    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.

    The text takes a unified approach to the subject, aiming to help the reader develop a real overview of chemical processes, byavoiding the traditional divisions of physical, inorganic and organic chemistry.To understand how chemical reactions happen we need to know about the bonding in molecules, how molecules interact, what determines whether an interaction is favorable or not, and what the outcome will be. Answering these questions requires an understanding of topics from quantum mechanics, throughthermodynamics, to curly arrows. In this book all of these topics are presented in a coherent and coordinated fashion, showing how each leads to a deeper understanding of chemical reactions.
