A long-treasured but forgotten classic of folk healing, with an introduction and commentary by the author of Backwoods Witchcraft and Doctoring the Devil.Ossman & Steel’s Guide to Health or Household Instructor (its original title) is a collection of spells, remedies, and charms. The book draws from the old Pennsylvania Dutch and German powwow healing practices that in turn helped shape Appalachian folk healing, conjure, rootwork, and many folk healing traditions in America. Jake Richards, author of Backwoods Witchcraft and Doctoring the Devil, puts these remedies in context, with practical advice for modern-day “backwoods” healers interested to use them today. The first part contains spells and charms for healing wounds, styes, broken bones, maladies, and illnesses of all sorts. The second part includes other folk remedies using ingredients based on sympathetic reasoning, including sulfuric acid, gunpowder, or other substances for swelling, toothache, headache, and so on. These remedies are presented here for historic interest, to help better understand how folk medicine evolved in America. It is Jake Richard’s hope that reintroducing this work will reestablish its position as a useful household helper in the library of every witch or country healer.Ver livro
Humans have long been aware of the electric and magnetic forces around us, and scientific investigation showed that the two are intimately connected as electromagnetism. Lightning shows how devastating electricity can be in nature, while humans learned to exploit the flow of negatively charged electrons that make up an electric current. In the early twentieth century, the experiments of Ernest Rutherford showed that at the heart of atoms lies a positively charged nucleus. The positive charge comes from protons. Atoms are neutral because the charges of the electron and proton cancel out. The charges of the proton and electron are opposite and equal, even though the proton is bigger. But why are they equal? This is one of the deepest unresolved puzzles of physics. Frank Close takes us on a journey into the quantum subatomic world of particles. He describes the strong and weak forces that operate alongside electromagnetism, the color and flavor charges, as well as the parallels between them, giving hints of a deeper unity. Seeking an answer to why matter is neutral brings us to fundamental forces and particles, the Standard Model, the Higgs boson, and implications of grand unification for the stability of matter. Close packs in a rich account of our current understanding and the latest ambitious experiments to probe further, and test theoretical possibilities.Ver livro

Discover the secret method used to build the world . . . For millennia, humans have used one simple method to solve problems. Whether it's planting crops, building skyscrapers, developing photographs, or designing the first microchip, all creators follow the same steps to engineer progress. But this powerful method, the "engineering method", is an all but hidden process that few of us have heard of—let alone understand—but that influences every aspect of our lives. Bill Hammack, a Carl Sagan Award–winning professor of engineering and viral "The Engineer Guy" on YouTube, has a lifelong passion for the things we make, and how we make them. Now, for the first time, he reveals the invisible method behind every invention and takes us on a whirlwind tour of how humans built the world we know today. From the grand stone arches of medieval cathedrals to the mundane modern soda can, Hammack explains the golden rule of thumb that underlies every new building technique, every technological advancement, and every creative solution that leads us one step closer to a better, more functional world. Spanning centuries and cultures, Hammack offers a fascinating perspective on how humans engineer solutions in a world full of problems.Ver livro
The amazing true story of the man behind modern weather predictionConsider a world without weather prediction. How would we know when to evacuate communities ahead of fires or floods, or figure out what to wear tomorrow? Until 40 years ago, we couldn’t forecast weather conditions beyond ten days. Renowned climate scientist Dr. Jagadish Shukla is largely to thank for modern weather forecasting. Born in rural India with no electricity, plumbing, or formal schools, he attended classes that were held in a cow shed. Shukla grew up amid turmoil: overwhelming monsoons, devastating droughts, and unpredictable crop yields. His drive brought him to the Indian Institute of Tropical Meteorology, despite little experience. He then followed an unlikely path to MIT and Princeton, and the highest echelons of climate science. His work, which has enabled us to predict weather farther into the future than previously thought possible, allows us to feed more people, save lives, and hold on to hope in a warming world.Paired with his philanthropic endeavors and extreme dedication to the field, Dr. Shukla has been lauded internationally for his achievements, including a shared Nobel Peace Prize with Al Gore for his governmental research on climate change. A Billion Butterflies is a wondrous insider’s account of climate science and an unbelievable memoir of his life. Understanding dynamical seasonal prediction will change the way you experience a thunderstorm or interpret a forecast; understanding its origins and the remarkable story of the man who discovered it will change the way you see our world.A Macmillan Audio production from St. Martin’s Press.Ver livro
A trove of 111 ingenious tips for seeing more birds wherever you are—from crowd favorites (hummingbirds, owls, eagles) to species you've never spotted before Seeing more birds than you ever imagined and witnessing exciting avian drama is possible—whether you're on the go or in your own neighborhood, local park, or backyard. As Heather Wolf explains, it all comes down to how you tune in to the show happening around you, the one in which birds—highly skilled at staying under the radar—are the stars. In Find More Birds, Heather shares her very best tactics. ● Look for birds at their favorite "restaurants"—from leaf litter to berry bushes, and ball fields to small patches of mud. ● Watch for "tree bark" that moves . . . you may find it has feathers. ● Try simply sitting on the ground for a revealing new perspective. Plus, special tips point the way to crowd favorites such as hummingbirds, owls, and eagles—and can't-miss bird behaviors. As your senses sharpen and "noticing" becomes second nature, Find More Birds will turn your daily routines into bird-finding adventures. Whether you're strolling down the block or parking your car, you never know what will surprise you next!Ver livro
