1: Elementary Theory and Problems contains the essential material that is usually covered in required courses of strength of materials in our engineering schools. Strength of Materials - Part. 2: Advanced Theory and Problems contains the later developments that are of practical importance in the fields of strength of materials, and theory of elasticity. Complete derivations of problems of practical interest are given in most cases. The books are illustrated with a number of problems to which solutions are presented. In many cases, the problems are chosen so as to widen the field covered by the text and to illustrate the application of the theory in the solution of design problems.

     The Octopus and the Orangutan finds intelligent behavior in surprising new places, ranging from the octopus's garden to the crow's nest. Amazing feats of stealth, deception, and larceny accompany unexpected acts of kindness and friendship. Animals show they are sensitive souls and tough negotiators both with their human keepers and with one another in this entirely new collection of stories sure to delight animal lovers everywhere.

    It considers the diversity and biology of bees, including their peculiar sociosexual arrangements (pity the poor drone), their quirky relationships with flowers, and their startling mental abilities: What are we to make of insects that communicate through symbolic dances? The book also addresses the mysterious syndrome known as colony collapse disorder and identifies opportunities for the conservation of pollinators.Enriched with cultural sidebars and complemented by a stunning collection of images, Bees is a must-read for conservationists, gardeners, and everyone else who cares about the world around them.Published in partnership with the David Suzuki Foundation.Also available in paperback.

    Starting with the story of her revolutionary discovery that elephants use infrasonic sounds--sounds below the range of human hearing--to communicate, Payne shares what she learned from her fascinating field research in Africa, research that reveals new insights into elephants' social lives. When five of the elephant families she studies are the victims of culling, Payne's approach to her research changes, as she fights valiantly to protect the elephants. The result of her research, and the touching insights gained from Africans she worked with and the elephants she studied, give a vivid impression of Payne's view from the front lines of the natural preservation effort. Like Peter Matthiessen's The Snow Leopard and the writings of Jane Goodall, Silent Thunder demonstrates how a commitment to all life can bring one's own into a new focus.

    From the Kansas City Star, "A wonderful story, wonderfully told, a history that delivers all the suspense and heartache of a novel, and is as difficult to put down"

    For among the finches of Daphne Major, natural selection is neither rare nor slow: it is taking place by the hour, and we can watch.In this dramatic story of groundbreaking scientific research, Jonathan Weiner follows these scientists as they watch Darwin's finches and come up with a new understanding of life itself. The Beak of the Finch is an elegantly written and compelling masterpiece of theory and explication in the tradition of Stephen Jay Gould.With a new preface.

    His powerful message, conveyed with humor, compassion, and art: to know these animals is to save them.Sartore intends to photograph every animal in captivity in the world. He is circling the globe, visiting zoos and wildlife rescue centers to create studio portraits of 12,000 species, with an emphasis on those facing extinction. He has photographed more than 6,000 already and now, thanks to a multi-year partnership with National Geographic, he may reach his goal. This book showcases his animal portraits: from tiny to mammoth, from the Florida grasshopper sparrow to the greater one-horned rhinoceros. Paired with the eloquent prose of veteran wildlife writer Douglas Chadwick, this book presents a thought-provoking argument for saving all the species of our planet.

    On closer investigation, dubious European naturalists eventually declared it to be real, though in an age obsessed with classification, the category-defying platypus sparked heated debates across Europe for a century. In Platypus, Ann Moyal provides a unique biography of one of the world's most famously strange creatures and tells the incredible story of how it became the focus of the great scientific debates of the nineteenth century. Eloquent and concise, Platypus uncovers the earliest theories and latest discoveries about this delightfully odd member of the animal kingdom.

    The projects are built around a focal cabochon and incorporate seed beads and crystals in imaginative ways. Designers learn to make the jewelry shown in the book, and they also use the techniques learned to create innovative jewelry pieces of their own.

    Nature’s many innovations—some uncannily perfect—call for natural principles that accelerate life’s ability to innovate.”Darwin’s theory of natural selection explains how useful adaptations are preserved over time. But the biggest mystery about evolution eluded him. As genetics pioneer Hugo de Vries put it, “natural selection may explain the survival of the fittest, but it cannot explain the arrival of the fittest.”Can random mutations over a mere 3.8 billion years really be responsible for wings, eyeballs, knees, camouflage, lactose digestion, photosynthesis, and the rest of nature’s creative marvels? And if the answer is no, what is the mechanism that explains evolution’s speed and efficiency?In Arrival of the Fittest, renowned evolutionary biologist Andreas Wagner draws on over fifteen years of research to present the missing piece in Darwin's theory. Using experimental and computational technologies that were heretofore unimagined, he has found that adaptations are not just driven by chance, but by a set of laws that allow nature to discover new molecules and mechanisms in a fraction of the time that random variation would take.Consider the Arctic cod, a fish that lives and thrives within six degrees of the North Pole, in waters that regularly fall below 0 degrees. At that temperature, the internal fluids of most organisms turn into ice crystals. And yet, the arctic cod survives by producing proteins that lower the freezing temperature of its body fluids, much like antifreeze does for a car’s engine coolant. The invention of those proteins is an archetypal example of nature’s enormous powers of creativity. Meticulously researched, carefully argued, evocatively written, and full of fascinating examples from the animal kingdom, Arrival of the Fittest offers up the final puzzle piece in the mystery of life’s rich diversity.

    The descriptive text includes information on size, geological period, geographical distribution, and ecology of the animal or plant before it was fossilized. In addition, the book provides lists of Geological Survey offices and major fossil collections, a geological time chart, and a guide to collecting and preserving fossils.

    Konrad Lorenz was gifted with a similar power of understanding the animal world. He was that rare beast, a brilliant scientist who could write (and indeed draw) beautifully. He did more than any other person to establish and popularize the study of how animals behave, receiving a Nobel Prize for his work. King Solomon's Ring, the book which brought him worldwide recognition, is a delightful treasury of observations and insights into the lives of all sorts of creatures, from jackdaws and water-shrews to dogs, cats and even wolves. Charmingly illustrated by Lorenz himself, this book is a wonderfully written introduction to the world of our furred and feathered friends, a world which often provides an uncanny resemblance to our own. A must for any animal-lover!

    Wind and earth, time, life, body and mind.

    Other bestselling works of neurobiology and the mind have focused on mental illness and abnormal behaviors—like the Oliver Sacks classic, The Man Who Mistook His Wife for a Hat—but The Other Side of Normal is an eye-opening, thought-provoking, utterly fascinating and totally accessible exploration of the universals of human experience. It will change forever our understanding of who we are and what makes us that way.
