    Everything around us, including matter, is energy. A deep look into the mysteries of the subatomic world – the particles that make up the atom – provides answers to basic questions about how the universe works. To solve the future of mankind’s energy needs we need to understand the basic building blocks of the universe, including the atom and its parts. By exploring the subatomic world we’ll find more answers to our questions about time, forces like gravity and the matter that surrounds us. More importantly, we’ll find new ways to tap into the energy that exists around us to power our growing needs. In a new branch of particle physics, where tiny particles are thought of as energy waves, we find new answers that may help us in our quest to find alternative energy sources.

    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.

    However, several revolutionary discoveries in the twentieth century revealed that there is a fundamental uncertainty at the heart of reality. Take a tour of chaos theory, the uncertainty principle, and read the saga of the South Pole and the Multiverse. Discover how uncertainty is the only certainty.

    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.

    Known for its carefully developed, thoroughly integrated, step-by-step approach to problem solving, General Chemistry helps students master quantitative skills and build a lasting conceptual understanding of key chemical concepts. The Ninth Edition retains this hallmark approach and builds upon the conceptual focus through key new features and revisions.

    The purpose of adaptation of this book is to make the learning experience more complete and help students develop a thought process about a given concept and build an aptitude to apply the same to solve a problem. The adaptation adds the distilled teaching expertise of the author to the original text, supplementing it with additional concepts and solved problems at appropriate places based on his experience of learning pattern of the students and obstacles in their learning curve.

    The goal of this book is to bring together quantum mechanics, the quantum theory of solids, semiconductor material physics, and semiconductor device physics in a clear and understandable way.

    Intuition and computational abilities are stressed. Original material on DE and multiple integrals has been expanded.

    • Useful for collegiate students as well as for those who are opting for entrance examinations.This completely new and innovative textbook provides a comprehensive account of pericyclic reactions and organic photochemistry for undergraduate and postgraduate courses. The approach is based on mechanism and reaction type, and the subject matter is developed and concentrated on better understanding rather than on merely grasping factual knowledge.Salient Features: • Basics of the subject are explained in thorough details. • Important points are revisited and mentioned wherever they are relevant. • Provides over 200 excellent thought-provoking textual problems. • Glossary and questions for self-assessment are given at the end of each chapter. • The most important aspect of this book is Chapter 14 which contains about 400 problems and their solutions based on pericyclic reactions and photochemistry. • Applied photochemistry is also discussed in the book.

    Its tale is one riddled with jealousy, rivalry, missed opportunities and moments of genius. Piers Bizony tells the story of the young misfit New Zealander, Ernest Rutherford, who showed that the atom consisted mainly of empty space, a discovery that turned 200 years of classical physics on its head, and the brilliant Dane, Niels Bohr, who made the next great leap into the incredible world of quantum theory. Yet he and a handful of other Young Turks in this revolutionary new science weren't prepared for the shocks that Nature had up her sleeve. At the dawn of the Atomic Age, a dangerous new force was unleashed with terrifying speed...

    Here, from author Jay Williams, is the moving story of the man behind the Renaissance myth.

     One of the most famous women of the twentieth century, Marie Curie was a trailblazer in the truest sense. Known for her discovery of two radioactive elements, radium and polonium, Marie Curie was the first woman to win a Nobel Prize. She remains the only woman to win two Nobel Prizes in different sciences. Inside you will read about... ✓ Early Life and Loss ✓ The Flying University ✓ Nobel Prizes ✓ Scandals ✓ Curie’s First World War Efforts ✓ The Discovery that Killed Her And much more! Marie Curie lived by her own rules in a society marred by misogyny and xenophobia. A scientist, but also a loving wife and mother, she defied expectations as a matter of course. Curie also fought for her country during the First World War the best way she knew how—with science. There is much more to Marie Curie’s story than the discovery of the radioactive elements that eventually killed her.
