Available in PDF, EPUB and Kindle. Book excerpt: Whether playing at defending their own castle or simply chucking pumpkins over a fence, wannabe marauders and tinkerers will become fast acquainted with Ludgar, the War Wolf, Ill Neighbor, Cabulus, and the Wild Donkey—ancient artillery devices known commonly as catapults. Building these simple yet sophisticated machines introduces fundamentals of math and physics using levers, force, torsion, tension, and traction. Instructions and diagrams illustrate how to build seven authentic working model catapults, including an early Greek ballista, a Roman onager, and the apex of catapult technology, the English trebuchet. Additional projects include learning how to lash and make rope and how to construct and use a hand sling and a staff sling. The colorful history of siege warfare is explored through the stories of Alexander the Great and his battle of Tyre; Saladin, Richard the Lionheart, and the Third Crusade; pirate-turned-soldier John Crabbe and his ship-mounted catapults; and Edward I of England and his battle against the Scots at Stirling Castle.

Available in PDF, EPUB and Kindle. Book excerpt: We've come a long way from the Peashooter Era: with the advent of modern household products and office supplies - foldback clips, clothespins, rubber bands, ballpoint pens, toothpicks, paper clips and plastic utensils - the everyday junk drawer can hold all the materials needed to create pocket-sized weaponry. Whether you're slowing dying of boredom in a stuffy office, plotting revenge on your older siblings or simply looking for a wonderful way to kill some time, this book is for you. Toy designer John Austin provides detailed, step-by-step instructions for each project, including materials and ammo lists, clear pictures, and construction tips, for mayhem-loving MacGyvers. The 35 devices include catapults, slingshots, darts, crossbows, and combustion shooters. Build a tiny trebuchet from paper clips and a D-cell battery. Wrap a penny in a string of paper caps to create a surprisingly impressive "bomb." Several of the projects even include variations where combatants mount laser pointer sights to their shooters to increase their accuracy. The instructions are simple so that anyone can make these wacky innovations in minutes whilst also learning about mechanics and physics in a fun, hands-on way.

Available in PDF, EPUB and Kindle. Book excerpt: "My son at 10yo (90-lbs) is highly coach-able. I taught him the system in February and he hit well during the season but could only hit the ball around 180'. Then all of a sudden around June he started killing the ball. He was hitting home runs every game and hit a ball at least 250-feet" - Michael Parillo (via email) Sick of struggling to help hitters drive the ball hard with more consistency? Dramatically increase power without sacrificing swing quality. Literally thousands of coaches across the nation are getting predictably positive results with hitters using the CLS system. How? By applying human movement principles validated by REAL science to hitting a ball, and NOT "bro-science." THIS STEP-BY-STEP GUIDE TO CONSISTENT POWER TEACHES: How to master a handful of human movement principles, so you can slice the "teach hitting" learning curve in half. How to effectively load the body, so your hitters can optimize their batted ball distance potential. How elite-hitters are revealing ways to hit balls with High-Exit-Speeds, swing after swing, using three elements a 4-year-old can understand. Why 'loading and exploding the hips' is bad for lower back, and how to teach hitters a highly effective but SAFE swing. THE NEW EXPANDED EDITION INCLUDES: 'How to practice' section at end of each movement principle Chapter. How to train a 2-year-old to hit a moving ball (proof that NOT only elite hitters can be taught these movements). Why pitchers are taught to pitch around ineffective swing paths, and how to turn their weapon against them. Why coaches MUST focus their hitters' efforts on targeting and elevating pitches low in the zone. How to teach timing and get hitters on-time more often in games.

Book excerpt: This "stunning journey through a country that is home to exhilarating natural wonders, and a scarring colonial past . . . makes breathtakingly clear the connection between nature and humanity, and offers a singular portrait of the complexities inherent to our ideas of identity, family, and love" (Refinery29). A chance discovery of letters written by her immigrant grandfather leads Jessica J. Lee to her ancestral homeland, Taiwan. There, she seeks his story while growing closer to the land he knew. Lee hikes mountains home to Formosan flamecrests, birds found nowhere else on earth, and swims in a lake of drowned cedars. She bikes flatlands where spoonbills alight by fish farms, and learns about a tree whose fruit can float in the ocean for years, awaiting landfall. Throughout, Lee unearths surprising parallels between the natural and human stories that have shaped her family and their beloved island. Joyously attentive to the natural world, Lee also turns a critical gaze upon colonialist explorers who mapped the land and named plants, relying on and often effacing the labor and knowledge of local communities. Two Trees Make a Forest is a genre–shattering book encompassing history, travel, nature, and memoir, an extraordinary narrative showing how geographical forces are interlaced with our family stories.

Book excerpt: A man’s home is his castle, or so the saying goes, but could it withstand an attack by Attila and the Huns, Ragnar and the Vikings, Alexander and the Greeks, Genghis Khan and the Mongols, or Tamerlane and the Tartars? Backyard Ballistics author William Gurstelle poses this fascinating question to modern-day garage warriors and shows them how to build an arsenal of ancient artillery and fortifications aimed at withstanding these invading hordes. Each chapter introduces a new bad actor in the history of warfare, details his conquests, and features weapons and fortifications to defend against him and his minions. Clear step-by-step instructions, diagrams, and photographs show how to build a dozen projects, including “Da Vinci’s Catapult,” “Carpini’s Crossbow,” a “Crusader-Proof Moat,” “Alexander’s Tortoise,” and the “Cheval-de-frise.” With a strong emphasis on safety, the book also gives tips on troubleshooting, explains the physics behind many of the projects, and shows where to buy the materials. By the time they’ve reached the last page, at-home defenders everywhere will have succeeded in creating a fully fortified home.

Available in PDF, EPUB and Kindle. Book excerpt: In this dark and ethereal debut novel, a young woman tries to make sense of strange artifacts and unsettling memories in an effort to find her mother—missing since being accused of murder When brutish miner Hugo Mitchum is found murdered on the frozen shore of a North Country lake, the local officials and town gossips of Beau Caelais are quick to blame Marietta Abernathy, outspoken environmental activist and angry, witchy recluse. But Marietta herself has disappeared under mysterious circumstances. Living on an isolated island with her father, Marietta’s sixteen-year-old daughter, Lena, begins sifting through her mother’s journals and collected oddities in an attempt to find her. While her father’s grief threatens to consume him and her adoptive aunt Bea reckons with guilt and acceptance, it is the haunting town outcast Ellis Olsen who might have the most to lose if Lena fails to find her mother. A Nordic eco-noir shot through with magical realism, Things We Found When the Water Went Down examines power, identity, and myth in a story that asks us to explore what it means to heal—or not—after violence.

Book excerpt: A New York Times Book Review Editors' Choice "A radiant first novel. . . . [Neon in Daylight] has antecedents in the great novels of the 1970s: Renata Adler’s Speedboat, Elizabeth Hardwick’s Sleepless Nights, Joan Didion’s Play It as It Lays. . . . Precision—of observation, of language—is Hoby’s gift. Her sentences are sleek and tailored. Language molds snugly to thought." —Parul Sehgal, The New York Times "What do you get when a writer of extreme intelligence, insight, style and beauty chronicles the lives of self–absorbed hedonists—The Great Gatsby, Bright Lights, Big City, and now Neon in Daylight. Hermione Hoby paints a garish world that drew me in and held me spellbound. She is a marvel."" —Ann Patchett, author of Commonwealth New York City in 2012, the sweltering summer before Hurricane Sandy hits. Kate, a young woman newly arrived from England, is staying in a Manhattan apartment while she tries to figure out her future. She has two unfortunate responsibilities during her time in America: to make regular Skype calls to her miserable boyfriend back home, and to cat–sit an indifferent feline named Joni Mitchell. The city has other plans for her. In New York's parks and bodegas, its galleries and performance spaces, its bars and clubs crowded with bodies, Kate encounters two strangers who will transform her stay: Bill, a charismatic but embittered writer made famous by the movie version of his only novel; and Inez, his daughter, a recent high school graduate who supplements her Bushwick cafe salary by enacting the fantasies of men she meets on Craigslist. Unmoored from her old life, Kate falls into an infatuation with both of them. Set in a heatwave that feels like it will never break, Neon In Daylight marries deep intelligence with captivating characters to offer us a joyful, unflinching exploration of desire, solitude, and the thin line between life and art.

Book excerpt: "Full of ideas and well-explained principles that will bring new understanding of everyday things to both scientists and non-scientists alike."—R. McNeill Alexander, Nature Nature and humans build their devices with the same earthly materials and use them in the same air and water, pulled by the same gravity. Why, then, do their designs diverge so sharply? Humans, for instance, love right angles, while nature's angles are rarely right and usually rounded. Our technology goes around on wheels—and on rotating pulleys, gears, shafts, and cams—yet in nature only the tiny propellers of bacteria spin as true wheels. Our hinges turn because hard parts slide around each other, whereas nature's hinges (a rabbit's ear, for example) more often swing by bending flexible materials. In this marvelously surprising, witty book, Steven Vogel compares these two mechanical worlds, introduces the reader to his field of biomechanics, and explains how the nexus of physical law, size, and convenience of construction determine the designs of both people and nature. "This elegant comparison of human and biological technology will forever change the way you look at each."—Michael LaBarbera, American Scientist
