do it? How should you flip your mattress to get the maximum wear out of it? How does Google search the Internet? How many people should you date before settling down? Believe it or not, math plays a crucial role in answering all of these questions and more.Math underpins everything in the cosmos, including us, yet too few of us understand this universal language well enough to revel in its wisdom, its beauty — and its joy. This deeply enlightening, vastly entertaining volume translates math in a way that is at once intelligible and thrilling. Each trenchant chapter of The Joy of x offers an “aha!” moment, starting with why numbers are so helpful, and progressing through the wondrous truths implicit in π, the Pythagorean theorem, irrational numbers, fat tails, even the rigors and surprising charms of calculus. Showing why he has won awards as a professor at Cornell and garnered extensive praise for his articles about math for the New York Times, Strogatz presumes of his readers only curiosity and common sense. And he rewards them with clear, ingenious, and often funny explanations of the most vital and exciting principles of his discipline.Whether you aced integral calculus or aren’t sure what an integer is, you’ll find profound wisdom and persistent delight in The Joy of x.

    Today, shifts in technology mean that language is increasingly one of symbols and metaphors, stories and images—not words.So what does this mean for the sermon, that long-standing, word-based tradition of Christianity?In this ground-breaking resource, bestselling author Leonard Sweet offers an alternative to traditional models of preaching, one that is fitting to a new culture and a new mode of thinking. The first book of its kind to move preaching beyond its pulpit-centric fixation and toward more interactive, participatory modes of communication, Sweet presents both a challenge and a path forward for a church struggling to maintain its relevance in a post-modern, media-saturated culture.

    He was a city boy, unsure of what lay ahead. When he entered the forest, which would go on to become one of the last strongholds of wild tigers, it had a profound effect on him, changing his life forever.For the next forty years, he studied nearly 200 Ranthambhore tigers, spending every waking moment in close proximity to these magnificent animals. Of the various tigers he observed a handful became extra special, and it is these which come to glorious life in this book. They include Padmini, the Queen Mother, the first tiger the author got to know well; Genghis, the master predator, who invented a way of killing prey in water, the first time this had been observed anywhere in the world; Noon, one of his all-time favourites, who received her name because she was most active in the middle of the day; Broken Tooth, an exceptionally gentle male; Laxmi, a devoted mother, whose methods of raising her cubs revolutionized tiger studies; Machli, the most famous tigress in Ranthambhore, and several more.

    Offering inspiration and intellectual delight, the problems throughout the book encourage students to express their ideas in writing to explain how they conceive problems, what conjectures they make, and what conclusions they reach. Applying specific techniques and strategies, readers will acquire a solid understanding of the fundamental concepts and ideas of number theory.

    But for those of us who left math behind in high school, the numbers and figures hurled at us as we go about our days can sometimes leave us scratching our heads and feeling as if we’re fumbling through a mathematical minefield.

     “Crime Squad takes readers on an unforgettable ride as Mike, an innocent lad from the Yorkshire Dales, learns to grow up fast and stay alive on the mean streets of London.” Weebly “A great read… gave a great feel of policing in the 80's and 90's in London, particularly with the change in drug culture and guns.” Netgalley “Well-written and informative, giving an insight into the workings of the police force in London in 1980s. Recommended.” Wendy Rhodes - Reviewer “A rollercoaster read of life on the front line.” Sir Hugh Orde OBE QPM “An accurate and fascinating picture of police work at the sharp end.” Detective Superintendent John Jones (rtd) “Gripping from first to last.” Andy Trotter OBE QPM London 1988: PC Mike Pannett, fresh out of training school, had suspected life in the Metropolitan Police was going to be a bit different from rural North Yorkshire, but the 23-year-old had no idea by just how much. Sent south of the river to Battersea, then top of London’s crime league tables, Mike was thrown straight into the deep end – during his first drugs raid he ended up staring down the wrong end of a double-barrelled shotgun. Mike’s arrival in London coincided with the explosion in crack cocaine use. In the early 1990s, Yardies – criminal gangs from Jamaica and the USA - flooded into the capital, starting in Battersea, where they brought all manner of guns with them, along with a live-fast die-young attitude. Rivals were ruthlessly eliminated and whole neighbourhoods fell under the control of drug gangs. Mike and his police colleagues fought back with extraordinary valour and inventiveness and with the support of the local community they started to turn the tide – but then came the unthinkable crime: the murder in 1993 of PC Patrick Dunne, one of Mike’s colleagues, by Gary Nelson, aka ‘Tyson’, a criminal the national press described as ‘the most dangerous man ever to walk to the streets of Britain.’ Mike was drawn into the long and exceptionally dangerous hunt for Nelson that would go on to cost the life of another police officer. Crime Squad takes readers on an unforgettable ride as Mike, an innocent lad from the Yorkshire Dales, learns to grow up fast and stay alive on the mean streets of London.

    Belknap's Waterproof Grand Canyon River Guide (All New Color Edition)

    With a hundred dollars in his pocket, a beat up cavalry saddle, and a faraway look in his eye, John Egenes saddled his horse Gizmo and started down the trail on an adventure across the North American continent. Their seven month journey took them across 11 states from California to Virginia, ocean to ocean.. As they left the pressing confinement of the city behind them, the pair experienced the isolation and loneliness of the southwestern deserts, the vastness of the prairie, and the great landscapes that make up America. Across hundreds of miles of empty land they slept with coyotes and wild horses under the stars, and in urban areas they camped alone in graveyards and abandoned shacks. Along the way John and Gizmo were transformed from inexperienced horse and rider to veterans of the trail. With his young horse as his spiritual guide John slowly began to comprehend his own place in the world and to find peace within himself. Full of heart and humor, Egenes serves up a tale that's as big as the America he witnessed, an America that no longer exists. It was a journey that could only have been experienced step by step, mile by mile, from the view between a horse's ears.

    His Incompleteness Theorem turned not only mathematics but also the whole world of science and philosophy on its head. Equally legendary were Gö's eccentricities, his close friendship with Albert Einstein, and his paranoid fear of germs that eventually led to his death from self-starvation. Now, in the first popular biography of this strange and brilliant thinker, John Casti and Werner DePauli bring the legend to life. After describing his childhood in the Moravian capital of Brno, the authors trace the arc of Gö's remarkable career, from the famed Vienna Circle, where philosophers and scientists debated notions of truth, to the Institute for Advanced Study in Princeton, New Jersey, where he lived and worked until his death in 1978. In the process, they shed light on Gö's contributions to mathematics, philosophy, computer science, artificial intelligence -- even cosmology -- in an entertaining and accessible way.
