Book Description
Guesstimation is a book that unlocks the power of approximation--it's popular mathematics rounded to the nearest power of ten! The ability to estimate is an important skill in daily life. More and more leading businesses today use estimation questions in interviews to test applicants' abilities to think on their feet. Guesstimation enables anyone with basic math and science skills to estimate virtually anything--quickly--using plausible assumptions and elementary arithmetic. Lawrence Weinstein and John Adam present an eclectic array of estimation problems that range from devilishly simple to quite sophisticated and from serious real-world concerns to downright silly ones. How long would it take a running faucet to fill the inverted dome of the Capitol? What is the total length of all the pickles consumed in the US in one year? What are the relative merits of internal-combustion and electric cars, of coal and nuclear energy? The problems are marvelously diverse, yet the skills to solve them are the same. The authors show how easy it is to derive useful ballpark estimates by breaking complex problems into simpler, more manageable ones--and how there can be many paths to the right answer. The book is written in a question-and-answer format with lots of hints along the way. It includes a handy appendix summarizing the few formulas and basic science concepts needed, and its small size and French-fold design make it conveniently portable. Illustrated with humorous pen-and-ink sketches, Guesstimation will delight popular-math enthusiasts and is ideal for the classroom.

Book Description
“A lively tale of historical innovation, the thrill of the bibliophile’s hunt, greed and betrayal.” – The New York Times Book Review "An addictive and engaging look at the ‘competitive, catty and slightly angst-ridden’ heart of the world of book collecting.” - The Houston Chronicle The never-before-told story of one extremely rare copy of the Gutenberg Bible, and its impact on the lives of the fanatical few who were lucky enough to own it. For rare-book collectors, an original copy of the Gutenberg Bible--of which there are fewer than 50 in existence--represents the ultimate prize. Here, Margaret Leslie Davis recounts five centuries in the life of one copy, from its creation by Johannes Gutenberg, through the hands of monks, an earl, the Worcestershire sauce king, and a nuclear physicist to its ultimate resting place, in a steel vault in Tokyo. Estelle Doheny, the first woman collector to add the book to her library and its last private owner, tipped the Bible onto a trajectory that forever changed our understanding of the first mechanically printed book. The Lost Gutenberg draws readers into this incredible saga, immersing them in the lust for beauty, prestige, and knowledge that this rarest of books sparked in its owners. Exploring books as objects of obsession across centuries, this is a must-read for history buffs, book collectors, seekers of hidden treasures, and anyone who has ever craved a remarkable book--and its untold stories.

The Living Elephants

ISBN: 0198026730
Category : Nature
Languages : en
Pages : 495

Book Description
The Living Elephants is the authoritative resource for information on both Asian and African elephants. From the ancient origins of the proboscideans to the present-day crisis of the living elephants, this volume synthesizes the behavior, ecology and conservation of elephants, while covering also the history of human interactions with elephants, all within the theoretical framework of evolutionary biology. The book begins with a survey of the 60-million year evolutionary history of the proboscideans emphasizing the role of climate and vegetation change in giving rise to a bewildering array of species, but also discussing the possible role of humans in the late Pleistocene extinction of mastodonts and mammoths. The latest information on the molecular genetics of African and Asian elephants and its taxonomic implications are then presented. The rise of the elephant culture in Asia, and its early demise in Africa are traced along with an original interpretation of this unique animal-human relationship. The book then moves on to the social life of elephants as it relates to reproductive strategies of males and females, development of behavior in young, communication, ranging patterns, and societal organization. The foraging strategies of elephants, their impact on the vegetation and landscape are then discussed. The dynamics of elephant populations in relation to hunting for ivory and their population viability are described with the aid of mathematical models. A detailed account of elephant-human interactions includes a treatment of crop depredation by elephants in relation to their natural ecology, manslaughter by elephants, habitat manipulation by humans, and a history of the ivory trade and poaching in the two continents. The ecological information is brought together in the final chapter to formulate a set of pragmatic recommendations for the long-term conservation of elephants. The broadest treatment of the subject yet undertaken, by one of the leading workers in the field, Raman Sukumar, the book promises to bring the understanding of elephants to a new level. It should be of interest not only to biologists but also a broader audience including field ecologists, wildlife administrators, historians, conservationists and all those interested in elephants and their future.

Book Description
Governments pay her. Criminals fear her. Nobody sees her coming. Vanessa “Michael” Munroe deals in information—expensive information—working for corporations, heads of state, private clients, and anyone else who can pay for her unique brand of expertise. Born to missionary parents in lawless central Africa, Munroe took up with an infamous gunrunner and his mercenary crew when she was just fourteen. As his protégé, she earned the respect of the jungle's most dangerous men, cultivating her own reputation for years until something sent her running. After almost a decade building a new life and lucrative career from her home base in Dallas, she's never looked back. Until now. A Texas oil billionaire has hired her to find his daughter who vanished in Africa four years ago. It’s not her usual line of work, but she can’t resist the challenge. Pulled deep into the mystery of the missing girl, Munroe finds herself back in the lands of her childhood, betrayed, cut off from civilization, and left for dead. If she has any hope of escaping the jungle and the demons that drive her, she must come face-to-face with the past that she’s tried for so long to forget. The first book in the Vanessa Michael Munroe series, gripping, ingenious, and impeccably paced, The Informationist marks the arrival or a thrilling new talent. “Stevens’s blazingly brilliant debut introduces a great new action heroine, Vanessa Michael Munroe, who doesn’t have to kick over a hornet’s nest to get attention, though her feral, take-no-prisoners attitude reflects the fire of Stieg Larsson’s Lisbeth Salander….Thriller fans will eagerly await the sequel to this high-octane page-turner.” —Publishers Weekly, starred, boxed review
