  A different kind of politics for a new kind of society—beyond work, scarcity, and capitalism 
   
   
   
  In the twenty-first century, new technologies should liberate us from work. Automation, rather than undermining an economy built on full employment, is instead the path to a world of liberty, luxury, and happiness—for everyone. Technological advance will reduce the value of commodities—food, healthcare, and housing—towards zero. 
   
   
   
  Improvements in renewable energies will make fossil fuels a thing of the past. Asteroids will be mined for essential minerals. Genetic editing and synthetic biology will prolong life, virtually eliminate disease, and provide meat without animals. New horizons beckon. 
   
   
   
  In Fully Automated Luxury Communism, Aaron Bastani conjures a vision of extraordinary hope, showing how we move to energy abundance, feed a world of 9 billion, overcome work, transcend the limits of biology, and establish meaningful freedom for everyone. Rather than a final destination, such a society merely heralds the real beginning of history.

  What the River Knows - Essays...

  Michael Engelhard

  Edward Abbey, who never much liked Alaska, called it "our biggest, buggiest, boggiest state." To others, it has been a cure for despair. When Michael Engelhard moved to Fairbanks more than three decades ago, he was a cheechako, a subarctic tenderfoot. Gathering skills and experiences the hard way, he attained "Sourdough" status while realizing there would always be more to learn, see, and do in the land of midnight sun and auroras. 
   
   
   
  En route, Engelhard suffered frostbite, stubborn yaks, grizzly charges, trophy hunters, cold-water immersion, heartbreak, incontinent raptors, one pesky squirrel, and honeymooners from abroad. He tried to rescue a raven and explored Arctic dunes and a glacier's blue heart, and his own as he mingled with caribou on their epic journeys.

  Relativity: The Special and...

  Albert Einstein

  This is an introduction to Einstein’s space-bending, time-stretching theory of Relativity, written by the master himself. Special and General relativity explain the structure of space time and provide a theory of gravitation, respectively. Einstein’s theories shocked the world with their counterintuitive results, including the dissolution of absolute time. In this book he brings a simplified form of his profound understanding of the subject to the layperson. In the words of Einstein: “The present book is intended, as far as possible, to give an exact insight into the theory of Relativity to those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics.” The book is challenging at times but, when approached patiently, proves itself one of the most lucid explanations of Relativity to be found anywhere. [Due to transcription or optical character recognition errors in creating online texts, and because of less-than-clear fonts in some printed texts, the variables as read in some of the equations here are not as Einstein intended. For example, the numeral ‘one’ has frequently been printed and read as the letter ‘I.’ In addition, some equations do not translate well into the spoken word. If you require completely accurate renditions of Einstein’s mathematical formulas, we suggest that you consult a published text.] — Summary written by Kelly Bescherer [and Laurie Anne Walden]

  Renowned herbalist Amy Blackthorn shows readers how to bring plant spirits into their daily spiritual practice with therapeutic access, subconscious learning, and divining skills that help them understand plant spirits on a deeper level.  Blackthorn’s Botanical Magic showed a new generation of witches how scent affects people, whether they understand it or not. In Blackthorn’s Book of Sacred Plant Magic, we travel even deeper into the magical garden of scent. We know that a walk down a summer street can bring back the smell of childhood summers with friends, riding bikes and swimming. Spring breezes carry with them the clean soapy smell of your second-grade teacher. We experience scents not only in the here and now but also filtered through the lens of our past. Using the power of scent, we can create a sense of the sacred in our daily lives. Part reference guide, part recipe book, and part ritual journey, Blackthorn’s Book of Sacred Plant Magic offers readers an in-depth exploration of the vital connection between scents and magical practice.   Topics covered include:  Connecting with Spirits of Plants, Place, and People  Expanding your Scent Vocabulary: Beyond “Floral”  Scent, Memory, and Personal History: How History Effects Scent  Creating Scent Activations

  Back-of-the-Envelope Physics

  From an award-winning teacher, “a delightful and instructive accessory to an introductory physics course” (Physics World). 
   
  Physicists use “back-of-the-envelope” estimates to check whether or not an idea could possibly be right. In many cases, the approximate solution is all that is needed. This compilation of 101 examples of back-of-the-envelope calculations celebrates a quantitative approach to solving physics problems. Drawing on a lifetime of physics research and nearly three decades as the editor of The Physics Teacher, Clifford Swartz—a winner of two awards from the American Association of Physics Teachers—provides simple, approximate solutions to physics problems that span a broad range of topics. What note do you get when you blow across the top of a Coke bottle? Could you lose weight on a diet of ice cubes? How can a fakir lie on a bed of nails without getting hurt? Does draining water in the northern hemisphere really swirl in a different direction than its counterpart below the equator? 
   
  In each case, only a few lines of arithmetic and a few natural constants solve a problem to within a few percent. Covering such subjects as astronomy, magnetism, optics, sound, heat, mechanics, waves, and electricity, this book provides a rich source of material for teachers and anyone interested in the physics of everyday life. 
   
  “This is a book that will help make the study of physics fun and relevant.” —Mark P. Silverman, author of Waves and Grains: Reflections on Light and Learning
