From the blue-blooded pockets of old-WASP New England to the vast tribal lands of the Navajo, Bryan Sykes takes us on a historical genetic tour, interviewing genealogists, geneticists, anthropologists, and everyday Americans with compelling ancestral stories. His findings suggest:• Of Americans whose ancestors came as slaves, virtually all have some European DNA.• Racial intermixing appears least common among descendants of early New England colonists.• There is clear evidence of Jewish genes among descendants of southwestern Spanish Catholics.• Among white Americans, evidence of African DNA is most common in the South.• European genes appeared among Native Americans as early as ten thousand years ago.An unprecedented look into America's genetic mosaic and an impressive contribution to how we perceive race, this is a fascinating book about what it means to be American.

    What, really, does E=MC2 mean? More fun than a slide rule, Handy Physics tackles the big issues: Gravity. Magnetism. Matter. Sound. Light. And the smaller topics, like why do cats always land on their feet? Why don't birds or squirrels on power lines get electrocuted? Only Handy Physics combines elementary theory with heartwarming tales of small animals. For everyone who ever wondered how a light bulb works, The Handy Physics Answer Book examines more than 825 basic questions about physics and physicists, ranging from everyday life applications to the latest explorations in subatomic physics. The Handy Physics Answer Book disposes with the mathematical explanations and deep coma often associated with physics and instead takes a more conceptual approach – written in everyday English by yet another teacher. Other great stuff includes a list of the Nobel Prize winners in physics and suggestions for further reading. Ideal for students, science readers, theatergoers, and anyone reckoning with the essential questions about the universe we dwell within, Handy Physics is a friendly guide to the most significant scientific theories and discoveries of our time. And, we promise, no chalkboards.

    

    Pothichoru has 5 stories including Mothiram, Marappavakal, Poovampazham and Pounder Pothan. Introductory study by M Achuthan.

    Every person alive today is descended from him. How did this real-life Adam wind up as the father of us all? What happened to the descendants of other men who lived at the same time? And why, if modern humans share a single prehistoric ancestor, do we come in so many sizes, shapes, and races?Examining the hidden secrets of human evolution in our genetic code, Spencer Wells reveals how developments in the revolutionary science of population genetics have made it possible to create a family tree for the whole of humanity. Replete with marvelous anecdotes and remarkable information, from the truth about the real Adam and Eve to the way differing racial types emerged, The Journey of Man is an enthralling, epic tour through the history and development of early humankind.

    Intermediate Accounting integrates this new information throughout the chapters so they'll learn how to apply the new global accounting standards. Global examples are presented to clearly show how the information is utilised in the field. The use of various currencies is also explored, which is critical for accountants to know in today's global businesses environment.

    It provides complete coverage of the new A- and AS-level core specifications being taught from September 2000 onwards and presents concepts in separate, easily accessible double-page spreads. Each spread starts with learning objectives and ends with questions, to check understanding, making the book particularly suitable for self-study.

    At a summer tea party in Cambridge, England, a guest states that tea poured into milk tastes different from milk poured into tea. Her notion is shouted down by the scientific minds of the group. But one man, Ronald Fisher, proposes to scientifically test the hypothesis. There is no better person to conduct such an experiment, for Fisher is a pioneer in the field of statistics.The Lady Tasting Tea spotlights not only Fisher's theories but also the revolutionary ideas of dozens of men and women which affect our modern everyday lives. Writing with verve and wit, David Salsburg traces breakthroughs ranging from the rise and fall of Karl Pearson's theories to the methods of quality control that rebuilt postwar Japan's economy, including a pivotal early study on the capacity of a small beer cask at the Guinness brewing factory. Brimming with intriguing tidbits and colorful characters, The Lady Tasting Tea salutes the spirit of those who dared to look at the world in a new way.

    The Other Brain is the story of glia, which make up approximately 85 percent of the cells in the brain. Long neglected as little more than cerebral packing material ("glia" means glue), glia are sparking a revolution in brain science.Glia are completely different from neurons, the brain cells that we are familiar with. Scientists are discovering that glia have their own communication network, which operates in parallel to the more familiar communication among neurons. Glia provide the insulation for the neurons, and glia even regulate the flow of information between neurons.But it is the potential breakthroughs for medical science that are the most exciting frontier in glia research today. Diseases such as brain cancer and multiple sclerosis are caused by diseased glia. Glia are now believed to play an important role in such psychiatric illnesses as schizophrenia and depression, and in neurodegenerative diseases such as Parkinson's and Alzheimer's. They are linked to infectious diseases such as HIV and prion disease (mad cow disease, for example) and to chronic pain. Scientists have discovered that glia repair the brain and spinal cord after injury and stroke. The more we learn about these cells that make up the "other" brain, the more important they seem to be.Written by a neuroscientist who is a leader in the research to reveal the secrets of these brain cells, The Other Brain offers a firsthand account of science in action. It takes us into the laboratories where important discoveries are being made, and it explains how scientists are learning that glial cells come in different types, with different capabilities. It tells the story of glia research from its origins to the most recent discoveries and gives readers a much more complete understanding of how the brain works and where the next breakthroughs in brain science and medicine are likely to come.

    But is this the most effective method of motivation? No, says psychologist Edward L. Deci, who challenges traditional thinking and shows that this method actually works against performance. The best way to motivate people—at school, at work, or at home—is to support their sense of autonomy. Explaining the reasons why a task is important and then allowing as much personal freedom as possible in carrying out the task will stimulate interest and commitment, and is a much more effective approach than the standard system of reward and punishment. We are all inherently interested in the world, argues Deci, so why not nurture that interest in each other? Instead of asking, "How can I motivate people?" we should be asking, "How can I create the conditions within which people will motivate themselves?""An insightful and provocative meditation on how people can become more genuinely engaged and succesful in pursuing their goals." —Publisher's Weekly
