By the time he died in 1991 he was truly the king of his remarkable wilderness, and internationally celebrated for his unique lifestyle.

    Following closely behind is y, or gamma, a constant that arises in many mathematical areas yet maintains a profound sense of mystery. In a tantalizing blend of history and mathematics, Julian Havil takes the reader on a journey through logarithms and the harmonic series, the two defining elements of gamma, toward the first account of gamma's place in mathematics. Introduced by the Swiss mathematician Leonhard Euler (1707-1783), who figures prominently in this book, gamma is defined as the limit of the sum of 1 + 1/2 + 1/3 + . . . Up to 1/n, minus the natural logarithm of n--the numerical value being 0.5772156. . . . But unlike its more celebrated colleagues π and e, the exact nature of gamma remains a mystery--we don't even know if gamma can be expressed as a fraction. Among the numerous topics that arise during this historical odyssey into fundamental mathematical ideas are the Prime Number Theorem and the most important open problem in mathematics today--the Riemann Hypothesis (though no proof of either is offered!). Sure to be popular with not only students and instructors but all math aficionados, Gamma takes us through countries, centuries, lives, and works, unfolding along the way the stories of some remarkable mathematics from some remarkable mathematicians.-- "Notices of the American Mathematical Society"

    Loosely based on the form of Chaucer's Canterbury Tales, Dawkins's Tale takes us modern humans back through four billion years of life on our planet. As the pilgrimage progresses, we join with other organisms at the forty "rendezvous points" where we find a common ancestor. The band of pilgrims swells into a vast crowd as we join first with other primates, then with other mammals, and so on back to the first primordial organism.Dawkins's brilliant, inventive approach allows us to view the connections between ourselves and all other life in a bracingly novel way. It also lets him shed bright new light on the most compelling aspects of evolutionary history and theory: sexual selection, speciation, convergent evolution, extinction, genetics, plate tectonics, geographical dispersal, and more. The Ancestor's Tale is at once a far-reaching survey of the latest, best thinking on biology and a fascinating history of life on Earth. Here Dawkins shows us how remarkable we are, how astonishing our history, and how intimate our relationship with the rest of the living world.

    Genealogists and adoptees are using them and other DNA tests to identify ancestors, confirm relationships, and measure their ethnicity. Unfortunately, there are many similar sounding tests and some of them have different testing levels. So it’s easy to order the wrong test or pay too much. This Guide to DNA Testing provides an easy-to-understand introduction to the different test types, their strengths and limitations. Author and adoptee, Richard Hill, shared his personal success story in his book, "Finding Family: My Search for Roots and the Secrets in My DNA.” Now he boils down the basics of genetic genealogy into this concise summary. Learn which tests are right for you. Hyperlinks to specific tests and resources are included.

    In writing the book James Stewart asked himself:What is essential for a three-semester calculus course for scientists and engineers? Stewart's SINGLE VARIABLE ESSENTIAL CALCULUS: EARLY TRANSCENDENTALS offers a concise approach to teaching calculus, focusing on major concepts and supporting those with precise definitions, patient explanations, and carefully graded problems. SINGLE VARIABLE ESSENTIAL CALCULUS: EARLY TRANSCENDENTALS is only 850 pages-two-thirds the size of Stewart's other calculus texts (CALCULUS, FIFTH EDITION AND CALCULUS, EARLY TRANSCENDENTALS, Fifth Edition)-yet it contains almost all of the same topics. The author achieved this relative brevity mainly by condensing the exposition and by putting some of the features on the website www.StewartCalculus.com. Despite the reduced size of the book, there is still a modern flavor: Conceptual understanding and technology are not neglected, though they are not as prominent as in Stewart's other books. SINGLE VARIABLE ESSENTIAL CALCULUS: EARLY TRANSCENDENTALS has been written with the same attention to detail, eye for innovation, and meticulous accuracy that have made Stewart's textbooks the best-selling calculus texts in the world.

    The title refers to the physiographic province of the United States that reaches from eastern Utah to eastern California, a silent world of austere beauty, of hundreds of discrete high mountain ranges that are green with junipers and often white with snow. The terrain becomes the setting for a lyrical evocation of the science of geology, with important digressions into the plate-tectonics revolution and the history of the geologic time scale.

    

    . . and one of nature’s last truly wild foods: the uncultivated, uncontrollable mushroom.Within the dark corners of America’s forests grow culinary treasures. Chefs pay top dollar to showcase these elusive and beguiling ingredients on their menus. Whether dressing up a filet mignon with smoky morels or shaving luxurious white truffles over pasta, the most elegant restaurants across the country now feature an abundance of wild mushrooms. The mushroom hunters, by contrast, are a rough lot. They live in the wilderness and move with the seasons. Motivated by Gold Rush desires, they haul improbable quantities of fungi from the woods for cash. Langdon Cook embeds himself in this shadowy subculture, reporting from both rural fringes and big-city eateries with the flair of a novelist, uncovering along the way what might be the last gasp of frontier-style capitalism. Meet Doug, an ex-logger and crabber—now an itinerant mushroom picker trying to pay his bills and stay out of trouble; and Jeremy, a former cook turned wild food entrepreneur, crisscrossing the continent to build a business amid cutthroat competition; their friend Matt, an up-and-coming chef whose kitchen alchemy is turning heads; and the woman who inspires them all. Rich with the science and lore of edible fungi—from seductive chanterelles to exotic porcini—The Mushroom Hunters is equal parts gonzo travelogue and culinary history lesson, a rollicking, character-driven tour through a world that is by turns secretive, dangerous, and tragically American.

    Two hours after their jump, all but three of these men were dead or mortally burned from a "blowup" -- an explosive, 2,000-degree firestorm 300 feet deep and 200 feet tall -- a deadly explosion of flame and wind rarely encountered and little understood at the time.  Only seconds ahead of the approaching firestorm, the foreman, R. Wagner Dodge, throws himself into the ashes of an "escape fire " - and survives as most of his confused men run, their last moments obscured by smoke. The parents of the dead cry murder, charging that the foreman's fire killed their boys.  Exactly what happened in Mann Gulch that day has been obscured by years of grief and controversy. Now a master storyteller finally gives the Mann Gulch fire its due as tragedy.     These first deaths among the Forest Service's elite firefighters prompted widespread examination of federal fire policy, of the field of fire science, and of the frailty of young men. For Maclean, who witnessed the fire from the ground in August of 1949,  and even then he knew he would one day become a part of its story.  It is a story of Montana, of the ways of wildfires, firefighters, and fire scientists, and especially of a crew, young and proud, who "hadn't learned to count the odds and to sense they might owe the universe a tragedy." This tale is also Maclean's own, the story of a writer obsessed by a strange and human horror, unable to let the truth die with these young men, searching for the last - and lasting - word. A canvas on which to tell many stories, including the story of his research into the story itself. And finally Nature's violence colliding with human fallibility.      Haunted by these deaths for forty years, Norman Maclean returned to the scene with two of the survivors and pursues the mysteries that Mann Gulch has kept hidden since 1949.  From the words of witnesses, the evidence of history, and the research of fire scientists, Maclean at last assembles the scattered pieces of the Mann Gulch tragedy; in his last work that consumed 14 years of his life, and earned a 1992 National Book Critics Circle Award.       The excruciating detail of this book makes for a sobering reading experience. Maclean -- a former University of Chicago English professor and avid fisherman -- also wrote A River Runs Through It and Other Stories , which is set along the Missouri River, one gulch downstream from Mann Gulch.       "A magnificent drama of writing, a tragedy that pays tribute to the dead and offers rescue to the living.... Maclean's search for the truth, which becomes an exploration of his own mortality, is more compelling even than his journey into the heart of the fire. His description of the conflagration terrifies, but it is his battle with words, his effort to turn the story of the 13 men into tragedy that makes this book a classic."          —  from New York Times Book Review Editor's Choice, Best Books of 1992 The Men who Perished in the Mann Gulch Fire: Robert J.
