This recreational math book takes the reader on a fantastic voyage into the world of natural numbers. From the earliest discoveries of the ancient Greeks to various fundamental characteristics of the natural number sequence, Clawson explains fascinating mathematical mysteries in clear and easy prose. He delves into the heart of number theory to see and understand the exquisite relationships among natural numbers, and ends by exploring the ultimate mystery of mathematics: the Riemann hypothesis, which says that through a point in a plane, no line can be drawn parallel to a given line.While a professional mathematician's treatment of number theory involves the most sophisticated analytical tools, its basic ideas are surprisingly easy to comprehend. By concentrating on the meaning behind various equations and proofs and avoiding technical refinements, Mathematical Mysteries lets the common reader catch a glimpse of this wonderful and exotic world.

    Powell first arrived at the servants' entrance of one of those great houses in the 1920s. As a kitchen maid - the lowest of the low - she entered an entirely new world; one of stoves to be blacked, vegetables to be scrubbed, mistresses to be appeased, and bootlaces to be ironed. Work started at 5:30am and went on until after dark. It was a far cry from her childhood on the beaches of Hove, where money and food were scarce, but warmth and laughter never were. Yet from the gentleman with a penchant for stroking the housemaids' curlers, to raucous tea-dances with errand boys, to the heartbreaking story of Agnes the pregnant under-parlormaid, fired for being seduced by her mistress's nephew, Margaret's tales of her time in service are told with wit, warmth, and a sharp eye for the prejudices of her situation. Margaret Powell's true story of a life spent in service is a fascinating "downstairs" portrait of the glittering, long-gone worlds behind the closed doors of Downton Abbey and 165 Eaton Place.

    Judy Melinek began her training as a New York City forensic pathologist. With her husband T.J. and their toddler Daniel holding down the home front, Judy threw herself into the fascinating world of death investigation, performing autopsies, investigating death scenes, counseling grieving relatives. Working Stiff chronicles Judy's two years of training, taking readers behind the police tape of some of the most harrowing deaths in the Big Apple, including a firsthand account of the events of September 11, the subsequent anthrax bio-terrorism attack, and the disastrous crash of American Airlines flight 587.Lively, action-packed, and loaded with mordant wit, Working Stiff offers a firsthand account of daily life in one of America's most arduous professions, and the unexpected challenges of shuttling between the domains of the living and the dead. The body never lies, and through the murders, accidents, and suicides that land on her table, Dr. Melinek lays bare the truth behind the glamorized depictions of autopsy work on shows like CSI and Law and Order to reveal the secret story of the real morgue.

    They became attached to each other, and Kerasote decided to name the dog Merle and bring him home. There, he realized that Merle's native intelligence would be diminished by living exclusively in the human world. He put a dog door in his house so Merle could live both outside and in.A deeply touching portrait of a remarkable dog and his relationship with the author, Merle's Door explores the issues that all animals and their human companions face as their lives intertwine, bringing to bear the latest research into animal consciousness and behavior as well as insights into the origins and evolution of the human-dog partnership. Merle showed Kerasote how dogs might live if they were allowed to make more of their own decisions, and Kerasote suggests how these lessons can be applied universally.

    She was a poor Southern tobacco farmer who worked the same land as her enslaved ancestors, yet her cells—taken without her knowledge—became one of the most important tools in medicine. The first “immortal” human cells grown in culture, they are still alive today, though she has been dead for more than sixty years. If you could pile all HeLa cells ever grown onto a scale, they’d weigh more than 50 million metric tons—as much as a hundred Empire State Buildings. HeLa cells were vital for developing the polio vaccine; uncovered secrets of cancer, viruses, and the atom bomb’s effects; helped lead to important advances like in vitro fertilization, cloning, and gene mapping; and have been bought and sold by the billions.Yet Henrietta Lacks remains virtually unknown, buried in an unmarked grave.Now Rebecca Skloot takes us on an extraordinary journey, from the “colored” ward of Johns Hopkins Hospital in the 1950s to stark white laboratories with freezers full of HeLa cells; from Henrietta’s small, dying hometown of Clover, Virginia — a land of wooden quarters for enslaved people, faith healings, and voodoo — to East Baltimore today, where her children and grandchildren live and struggle with the legacy of her cells.Henrietta’s family did not learn of her “immortality” until more than twenty years after her death, when scientists investigating HeLa began using her husband and children in research without informed consent. And though the cells had launched a multimillion-dollar industry that sells human biological materials, her family never saw any of the profits. As Rebecca Skloot so brilliantly shows, the story of the Lacks family — past and present — is inextricably connected to the history of experimentation on African Americans, the birth of bioethics, and the legal battles over whether we control the stuff we are made of.Over the decade it took to uncover this story, Rebecca became enmeshed in the lives of the Lacks family—especially Henrietta’s daughter Deborah, who was devastated to learn about her mother’s cells. She was consumed with questions: Had scientists cloned her mother? Did it hurt her when researchers infected her cells with viruses and shot them into space? What happened to her sister, Elsie, who died in a mental institution at the age of fifteen? And if her mother was so important to medicine, why couldn’t her children afford health insurance?Intimate in feeling, astonishing in scope, and impossible to put down, The Immortal Life of Henrietta Lacks captures the beauty and drama of scientific discovery, as well as its human consequences.

    Now Alan Alda has written a memoir as elegant, funny, and affecting as his greatest performances."My mother didn't try to stab my father until I was six," begins Alda's irresistible story. The son of a popular actor and a loving but mentally ill mother, he spent his early childhood backstage in the erotic and comic world of burlesque and went on, after early struggles, to achieve extraordinary success in his profession.Yet Never Have Your Dog Stuffed is not a memoir of show-business ups and downs. It is a moving and funny story of a boy growing into a man who then realizes he has only just begun to grow.It is the story of turning points in Alda's life, events that would make him what he is-if only he could survive them.From the moment as a boy when his dead dog is returned from the taxidermist's shop with a hideous expression on his face, and he learns that death can't be undone, to the decades-long effort to find compassion for the mother he lived with but never knew, to his acceptance of his father, both personally and professionally, Alda learns the hard way that change, uncertainty, and transformation are what life is made of, and true happiness is found in embracing them.Never Have Your Dog Stuffed, filled with curiosity about nature, good humor, and honesty, is the crowning achievement of an actor, author, and director, but surprisingly, it is the story of a life more filled with turbulence and laughter than any Alda has ever played on the stage or screen.
