It has been developed in response to the need for a text that supports the mastery of this difficult subject. Therefore, in addition to presenting electromagnetics in a concise and logical manner, the text includes end-of-section review questions, worked examples, boxed remarks that alert students to key ideas and tricky points, margin notes, and point-by-point chapter summaries. Examples and applications invite students to solve problems and build their knowledge of electromagnetics. Application topics include: electric motors, transmission lines, waveguides, antenna arrays and radar systems.

    We can't see air moving, though we can watch it push clouds across the sky, or shake the leaves of a tree. We call moving air the wind. In this enlarged edition, find out about the wind - what causes it, how it can be used to help us, and how it affects the weather.

    When Peep visits Ducky on a rainy day, the little pals have no trouble finding things to do. Inside, there is a tent to build and a pillow fight to be had. And outside, with the help of galoshes and umbrella, it’s fun to captain a boat—until a whoosh of wind and a clap of thunder sends them running back in! Perfectly tuned to a toddler sensibility, this exuberant tale will enchant both listener and reader.

    Drawing on a wealth of expertise to explain just what a fascinating field quantum physics is, Rae points out that it is not simply a maze of technical jargon and philosophical ideas, but a reality which affects our daily lives.

    This beautifully illustrated and practical treasure trove of climate lore will enlighten outdoorsmen, farmers, sailors, and anyone else who has ever wondered what a large halo around the moon means, why birds "sit it out" before a storm, and whether or not to take an umbrella when leaving the house.

    If you like Wired Magazine and popular science books, you'll love the "hidden history" of The Battery.

    This brilliant work heralds the new age of nanotechnology, which will give us thorough and inexpensive control of the structure of matter.  Drexler examines the enormous implications of these developments for medicine, the economy, and the environment, and makes astounding yet well-founded projections for the future.

    The 378 dramatic photographs capture cloud types, precipitation, storms, twisters, and optical phenomena such as the Northern Lights. Essays with accompanying maps and illustrations discuss the earth's atmosphere, weather systems, cloud formation, and development of tornadoes and many other weather events.

    This book, which accompanies the major Channel 4 series, brings to life the hidden history of codes and code breaking. Since the birth of writing, there has also been the need for secrecy. The story of codes is the story of the brilliant men and women who used mathematics, linguistics, machines, computers, gut instinct, logic and detective work to encrypt and break these secrect messages and the effect their work has had on history. In each episode of "The Science of Secrecy" Simon Singh tells us a fascinating story from the history of codes: how the course of Crimean War was changed by the cracking of "unbreakable" Vigenere code; how the well-timed cracking of a single encoded telegram altered the course of World War I or how the mysteries of the Rosetta stone were revealed. The programme, and book, also investigates present day concerns about privacy on the internet and public key cryptography and looks to the future and the possibilities that quantum computing will radically change the science of secrecy in the 21st century.

    Striking images, models and illustrations offer a unique view of catastrophic weather conditions allowing readers to see into the eye of a cyclone, witness hailstones the size of tennis balls, and learn how a gentle mountain stream can become a raging surge within a few minutes. Learn the techniques developed through the centuries to forecast weather, see a chicken that was stripped of its feathers by a tornado, and how human activity can cause weather patterns to change.For over 25 years, DK's "Eyewitness" books have been the most trusted nonfiction series in classrooms, libraries, and homes around the world.

    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.

    •Practice exercises are given at the end of chapter included conceptual questions & multiple choice questions with hints, answer & solutions. •Multiple choice questions with single correct and more the one correct answers, Comprehension based questions, Assertion-Reason, Matching Type questions, etc. •Every reaction is explained mechanistically for subject understanding. •Solutions are given at the end of every chapter for clear the concepts.

Too many people have suffered for far too long. It’s time for a change. It's time you found relief. Glenn Schweitzer was 24 years old when a rare, incurable inner ear disorder caused him to develop severe tinnitus. It disrupted nearly every aspect of his life. But today, his tinnitus no longer bothers him at all. Completely by accident, he stumbled on to simple techniques that radically rewired his mental, emotional, and physiological response to the sound.  Through Glenn’s terrifying, yet inspiring story, and with dozens of actionable techniques and tools, you can finally find the relief you deserve, too. You will learn specific techniques to reduce your tinnitus, as well as concrete steps to dramatically improve your quality of life.
