"It would be hard to design a more reliable timekeeper." In Nature's Clocks, Macdougall tells how scientists who were seeking to understand the past arrived at the ingenious techniques they now use to determine the age of objects and organisms. By examining radiocarbon (C-14) dating—the best known of these methods—and several other techniques that geologists use to decode the distant past, Macdougall unwraps the last century's advances, explaining how they reveal the age of our fossil ancestors such as "Lucy," the timing of the dinosaurs' extinction, and the precise ages of tiny mineral grains that date from the beginning of the earth's history. In lively and accessible prose, he describes how the science of geochronology has developed and flourished. Relating these advances through the stories of the scientists themselves—James Hutton, William Smith, Arthur Holmes, Ernest Rutherford, Willard Libby, and Clair Patterson—Macdougall shows how they used ingenuity and inspiration to construct one of modern science's most significant accomplishments: a timescale for the earth's evolution and human prehistory.

    Harlen Bretz walked the dry scabland channels of eastern Washington in the 1920s, it dawned on him that he was viewing a landscape sculpted by water. Lots of water. A flood of catastrophic proportions. Glacial Lake Missoula and Its Humongous Floods tells the gripping tale of a huge Ice Age lake that drained suddenly--not just once but repeatedly--and reshaped the landscape of the Northwest. The narrative follows the path of the floodwaters as they raged from western Montana across the Idaho Panhandle, then scoured through eastern Washington and down the Columbia Gorge to the Pacific Ocean. This is also the story of geologists grappling with scientific controversy--"of how personalities, pride, and prejudice sometimes superseded scientific evidence."

    According to the authors,effective human resource management is necessary for a firm to gain true competitive advantage. The three challenges companies face are the global challenge,the challenge of meeting stakeholder needs,and the high performance work practices challenge. HUMAN RESOURCE MANAGEMENT provides students with the technical background needed to be a successful HR professional,to manage HR effectively,and most importantly to be a knowledgeable consumer of HR products and services. The text also emphasizes how managers can more effectively acquire,develop,compensate,and manage the internal and external environment that relates to the management of human resources.

    Ana Lund never knew how true this was until she went away to college. Now, back for winter break just after her first semester away, Ana desperately wants to stay home, but doesn’t know how to tell her parents. Then one day an old friend is in need of a last-minute babysitter, and Ana volunteers.Divorced at twenty-one with a three year old son, Caleb understands Ana’s fear of disappointing her parents, but he also knows that the sooner she talks to them, the better. With his encouragement she’s able to talk to her parents about what she wants, and as she settles back into her life on the island, she and Caleb start to grow closer. Both of them homebodies, they share the same desire for a quiet, uncomplicated life filled with family and friends. But after his disastrous relationship with his ex-wife ended in bitter divorce, Caleb is in no hurry to repeat past mistakes. In the end is love enough? Or are some things just meant to be repeated?

    The study of knots has led to important applications in DNA research and the synthesis of new molecules, and has had a significant impact on statistical mechanics and quantum field theory. Colin Adams’s The Knot Book is the first book to make cutting-edge research in knot theory accessible to a non-specialist audience. Starting with the simplest knots, Adams guides readers through increasingly more intricate twists and turns of knot theory, exploring problems and theorems mathematicians can now solve, as well as those that remain open. He also explores how knot theory is providing important insights in biology, chemistry, physics, and other fields. The new paperback edition has been updated to include the latest research results, and includes hundreds of illustrations of knots, as well as worked examples, exercises and problems. With a simple piece of string, an elementary mathematical background, and The Knot Book, anyone can start learning about some of the most advanced ideas in contemporary mathematics.

    

    The focus is on algorithms and hence the book is well suited for students in computer science and engineering. Motivation is provided from the application areas: all solutions and techniques from computational geometry are related to particular applications in robotics, graphics, CAD/CAM, and geographic information systems. For students this motivation will be especially welcome. Modern insights in computational geometry are used to provide solutions that are both efficient and easy to understand and implement. All the basic techniques and topics from computational geometry, as well as several more advanced topics, are covered. The book is largely self-contained and can be used for self-study by anyone with a basic background in algorithms. In the second edition, besides revisions to the first edition, a number of new exercises have been added.

    This work offers accesible coverage of the fundamentals of electrodynamics, enhanced with with discussion points, examples and exercises.
