    Cameron Webb’s brief but biting assault on the wide spectrum of religiosity that dominates 21st century America, from the hateful and anti-intellectual dogma of the Christian Right to the whitewashed progressivism of religious moderates. It is also a fascinating and humbling journey into the heart of the universe's most mind-numbing wonders.Drawing on recent insights from cosmology and evolution, Despicable Meme paints a vivid portrait of a cosmos unlike anything ever imagined by the provincial, human-centered faiths of the past – a universe of countless worlds spread across unfathomable distances and times, and where, on at least one of those worlds, the slow march of time would combine with the purposeless mechanisms of chemistry and physics to create a being capable of believing that he alone is the reason for it all.With piercing intelligence and candor, Despicable Meme exposes the folly of that conceit and dispenses with the widespread but utterly improbable notion of a personal creator. But it saves its harshest criticism for the vapid accommodationism of religious liberals, those who unknowingly or uncaringly give cover to the misogynistic, racist, homophobic paranoia of the fanatics by refusing to condemn, or quietly tolerating, the outlandish and immoral doctrines that lie festering at the center of their own “moderate” faiths.Despicable Meme is not only a blistering condemnation of radical fundamentalism, it is an impassioned appeal to the rest of us to once and for all abandon the superstitions of the religion we were raised in and embrace the beauty of an endlessly wondrous, but godless, universe.Show less

    But Max Leonard, himself an accomplished amateur cyclist, does not forget the pain, the glory, the sweat, and the tears that go into these grueling climbs.  After all, cycling up a mountain is hard.  So hard that, to many, it can seem absurd. But for others, climbing a mountain gracefully (and beating your competitors up the slope) represents the pinnacle of cycling achievement. It is where legends are forged.Many books tell you where the mountains are, or how long and how high. None of them ask why. Why are mountain ranges professional cycling’s Coliseum? Why do amateurs also make pilgrimages to these high, remote roads? Why are the roads even there in the first place to lure us on to these obsession inducing climbs?   Just why are mountains so enthralling? “This is real cycling, where the glory is and where dreams come true,” according to Bradley Wiggins. Mountains are where cycling's greatest heroes have made their names. Every amateur rider wishes they could climb better, too.  Are all these people addicted to the pain? To the achievement? Or to the allure of the peaks? Some spend their weekends and holidays cycling up mountains from start to finish. But how does a rider push themselves beyond their limits to get up a 10% gradient on pedal power alone? What is happening when they do?A Higher Calling explores the central place of mountains in the folklore of road cycling. Blending adventure and travel writing with the rich narrative of racing, Max Leonard takes the reader from the battles that created the Alpine roads to the shepherds tending their flocks on the peaks, and to a Grand Tour climax on the “highest road in Europe.” And he tells stories of courage and sacrifice, war and love, obsession and even elephants, along the way.

    This is Nick's story of his world record-breaking adventure and the extraordinary people who joined him along the way. On January 6th 2018, Nick Butter tied his laces and stepped out on to an icy pavement in Toronto, where he began to take the first steps of an epic journey that would see him run 196 marathons in every one of the world's 196 countries. Spending almost two years on the road and relying on the kindness of strangers to keep him moving, Nick's odyssey allowed him to travel slowly, on foot, immersing himself in the diverse cultures and customs of his host nations. Running through capital cities and deserts, around islands and through spectacular landscapes, Nick dodges bullets in Guinea-Bissau, crosses battlefields in Syria, survives a wild dog attack in Tunisia and runs around an erupting volcano in Guatemala. Along the way, he is often joined by local supporters and fellow runners, curious children and bemused passers-by. Telling their stories alongside his own, Nick captures the unique spirit of each place he visits and forges a new relationship with the world around him. Running the World captures Nick's journey as he sets three world records and covers over five thousand miles. As he recounts his adventures, he shares his unique perspective on our glorious planet, celebrates the diversity of human experience, and reflects on the overwhelming power of running.

    She entered Ah-gwah-ching State Sanatorium at Walker, Minnesota, for what she thought would be a short stay. In January, her tuberculosis spread, and she nearly died. Her recovery required many months of bed rest and medical care.Marilyn loved to write, and the story of her three-year residency at the sanatorium is preserved in hundreds of letters that she mailed back home to her parents, who could visit her only occasionally and whom she missed terribly. The letters functioned as a diary in which Marilyn articulately and candidly recorded her reactions to roommates, medical treatments, Native American nurses, and boredom. She also offers readers the singular perspective of a bed-bound teenager, gossiping about boys, requesting pretty new pajamas, and enjoying Friday evening popcorn parties with other patients.Selections from this cache of letters are woven into an informative narrative that explores the practices and culture of a midcentury tuberculosis sanatorium and fills in long-forgotten details gleaned from recent conversations with Marilyn, who "graduated" from the sanatorium and went on to lead a full, productive life.

    Everything around us, including matter, is energy. A deep look into the mysteries of the subatomic world – the particles that make up the atom – provides answers to basic questions about how the universe works. To solve the future of mankind’s energy needs we need to understand the basic building blocks of the universe, including the atom and its parts. By exploring the subatomic world we’ll find more answers to our questions about time, forces like gravity and the matter that surrounds us. More importantly, we’ll find new ways to tap into the energy that exists around us to power our growing needs. In a new branch of particle physics, where tiny particles are thought of as energy waves, we find new answers that may help us in our quest to find alternative energy sources.
