  Pleistocene Era The: The History...

  The Pleistocene spans a period from around 2.5 mya to just over 12,000 years ago, and it was an epoch of enormous change on Earth, mainly characterized by climate changes involving fluctuations between periods of extreme heat and long periods of glaciation. This period is commonly known as the Ice Age despite the fact there were actually a number of separate periods of cold.  
  	Along with the climate challenges, this was also the period that saw the development of modern humans. The origin of our ancient ancestors is still a matter of debate amongst paleontologists, and classification systems for early hominoids are constantly being updated as new discoveries are made. What is generally agreed upon is the species Homo sapiens belong to the order primates and the sub-order anthropoids. Within the anthropoids sub-order, humans belong to the family hominids, which also includes other animals such as the orangutan and the great apes. Drilling down even further, humans belong to a sub-group of hominids known as hominin. The sub-group hominin includes humans, as well as chimpanzees and gorillas. 
  	Discoveries have revealed more than twenty species of the genus Homo, all of which appeared during the Pleistocene Epoch, and all but Homo sapiens became extinct during the same period. It is generally accepted that hominoids and the first hominins evolved in what is now Africa. Somewhere around 7 mya, the common hominoid lineage split into two distinct evolutionary lines: the ancestors of modern chimpanzees and those of modern humans. Around 2.5 mya, a new genus of hominin appeared. Homo had larger brains than their predecessors as well as smaller jaws and teeth. The very first stone tools date to this period when there were a number of different hominin species. The very first true humans, Homo erectus, appeared around 2 mya.

  For centuries, it was assumed that our universe was static. Then, in the late 1920s, astronomers made a startling new discovery—from Earth, the light of distant galaxies appeared to be red. This meant those galaxies were receding from us, and a revolutionary realization was born: the universe is expanding. In The Red Limit, Timothy Ferris recounts the fascinating tale of this discovery, its far-reaching ramifications, and the passionately competitive astronomers who charted the past, present, and future of the cosmos.

  In the tradition of Mark Kurlansky's Cod and David Bodanis's E=MC2, The Battery is the first popular history of the technology that harnessed electricity and powered the greatest scientific and technological advances of our time.What began as a long-running dispute in biology, involving a dead frog's twitching leg, a scalpel, and a metal plate, would become an invention that transformed the history of the world: the battery. From Alessandro Volta's first copper-and-zinc model in 1800 to twenty-first-century technological breakthroughs, science journalist Henry Schlesinger traces the history of this essential power source and demonstrates its impact on our lives.Volta's first battery not only settled the frog's leg question, it also unleashed a field of scientific research that led to the discovery of new elements and new inventions, from Samuel Morse's telegraph to Alexander Graham Bell's telephone to Thomas Edison's incandescent lightbulb. And recent advances like nanotechnology are poised to create a new generation of paradigm-shifting energy sources.Schlesinger introduces the charlatans and geniuses, paupers and magnates, attracted to the power of the battery, including Michael Faraday, Guglielmo Marconi, Gaylord Wilshire, and Hugo Gernsback, the publisher and would-be inventor who coined the term "science fiction." A kaleidoscopic tour of an ingenious invention that helped usher in the modern world, The Battery is as entertaining as it is enlightening.

  The audiobook is a set of postulates illustrating observations that are ascertained by a different way to look at the new order of the cosmos. Redshift information paradox, binary constant, disconstantality of light, Big Bang steady state theory and others are creations of a creative and innovative way to look at the science of discovery. Each subset has its own observations proving the existence and validity of the theorem.

  A Bolt from the Blue - The Epic...

  FIVE INJURED CLIMBERS. TEN SEASONED RANGERS. ONE IMPOSSIBLE RESCUE.On the afternoon of July 26, 2003, six vacationing mountain climbers ascended the peak of the Grand Teton in Jackson Hole, Wyoming. Rain and colliding air currents blew in, and soon a massive electrical charge began to build. As the group began to retreat from its location, a colossal lightning bolt struck and pounded through the body of every climber. One of the six died instantly, one lay critically injured next to her body, and four dangled perilously into the chasm below. In riveting, page-turning prose, veteran journalist Jennifer Woodlief tells the story of the climb, the arrival of the storm, and the unprecedented rescue by the Jenny Lake Rangers, one of the most experienced climbing search-and-rescue teams in the country. Against the dramatic landscape of the Teton Range, Woodlief brings to life the grueling task of the rangers, a band of colorful characters who tackle one of the riskiest, most physically demanding jobs in the world. By turns terrifying and exhilarating, A Bolt from the Blue is both a testament to human courage and an astonishing journey into one of history’s most dangerous mountain rescues.

  The Boom - How Fracking Ignited...

  The "best all-around book yet on fracking" (San Francisco Chronicle) from a Pulitzer Prize finalist: "Gold's work is a tour de force of contemporary journalism" (Booklist). 
   
  First invented in 1947, hydraulic fracturing, or fracking, has not only become a major source of energy, it is changing the way we use energy, and the energy we use. It is both a threat and a godsend for the environment, and it is leading the revival of manufacturing in the United States. 
   
  A definitive narrative history, The Boom follows the twists and turns in the development and adoption of this radical technology. It is a thrilling journey filled with colorful characters: the green-minded Texas oilman who created the first modern frack; a bare-knuckled Oklahoman natural gas empire-builder who gave the world an enormous new supply of energy and was brought down by his own success and excesses; an environmental leader whose embrace of fracking brought an end to his public career; and an aging fracking pioneer who is now trying to save the industry from itself. 
   
  A fascinating and exciting exploration of one of the most controversial and promising sources of energy, The Boom "brings new clarity to a subject awash in hype from all sides…a thoughtful, well-written, and carefully researched book that provides the best overview yet of the pros and cons of fracking. Gold quietly leads both supporters and critics of drilling to consider other views" (Associated Press).
