  Boltzmann's Atom - The Great...

  In 1900 many eminent scientists did not believe atoms existed, yet within just a few years the atomic century launched into history with an astonishing string of breakthroughs in physics that began with Albert Einstein and continues to this day. Before this explosive growth into the modern age took place, an all-but-forgotten genius strove for forty years to win acceptance for the atomic theory of matter and an altogether new way of doing physics. Ludwig Boltz-mann battled with philosophers, the scientific establishment, and his own potent demons. His victory led the way to the greatest scientific achievements of the twentieth century.Now acclaimed science writer David Lindley portrays the dramatic story of Boltzmann and his embrace of the atom, while providing a window on the civilized world that gave birth to our scientific era. Boltzmann emerges as an endearingly quixotic character, passionately inspired by Beethoven, who muddled through the practical matters of life in a European gilded age.Boltzmann's story reaches from fin de siècle Vienna, across Germany and Britain, to America. As the Habsburg Empire was crumbling, Germany's intellectual might was growing; Edinburgh in Scotland was one of the most intellectually fertile places on earth; and, in America, brilliant independent minds were beginning to draw on the best ideas of the bureaucratized old world.Boltzmann's nemesis in the field of theoretical physics at home in Austria was Ernst Mach, noted today in the term Mach I, the speed of sound. Mach believed physics should address only that which could be directly observed. How could we know that frisky atoms jiggling about corresponded to heat if we couldn't see them? Why should we bother with theories that only told us what would probably happen, rather than making an absolute prediction? Mach and Boltzmann both believed in the power of science, but their approaches to physics could not have been more opposed. Boltzmann sought to explain the real world, and cast aside any philosophical criteria. Mach, along with many nineteenth-century scientists, wanted to construct an empirical edifice of absolute truths that obeyed strict philosophical rules. Boltzmann did not get on well with authority in any form, and he did his best work at arm's length from it. When at the end of his career he engaged with the philosophical authorities in the Viennese academy, the results were personally disastrous and tragic. Yet Boltzmann's enduring legacy lives on in the new physics and technology of our wired world.Lindley's elegant telling of this tale combines the detailed breadth of the best history, the beauty of theoretical physics, and the psychological insight belonging to the finest of novels.

  Purified - How Recycled Sewage...

  In Purified, veteran journalist Peter Annin shows that wastewater has become a surprising weapon in America's war against water scarcity. Annin probes deep into the water reuse movement in five water-strapped states—California, Texas, Virginia, Nevada, and Florida. He drinks beer made from purified sewage, visits communities where purified sewage came to the rescue, and examines how one of the nation's largest wastewater plants hopes to recycle one hundred percent of its wastewater by 2035. At each stop, listeners come face to face with the people who are struggling for, and against, recycled water. While the current filtration technology transforms sewage into something akin to distilled water—free of chemicals and safe to drink—water recycling's challenge isn't technology. It's terminology. Concerns about communities being used as "guinea pigs," sensationalist media coverage, and taglines like "toilet to tap" have repeatedly crippled water recycling efforts. Potable water recycling has become the hottest frontier in the race for expanded water supply options. But can public opinion turn in time to avoid the worst consequences? Purified's fast-paced narrative cuts through the fearmongering and misinformation to make the case that recycled water is direly needed in the climate-change era. Water cannot be taken for granted anymore—and that includes sewage.

  Backache has become one of the most pervasive of all ailments on a worldwide basis. This is a shame since backache that has not been caused by single impact trauma is largely preventable, as it is the result of ignorance. 
  Backache has been given status as a watchword for scammer, since it is so difficult to disprove that some people have used it as an excuse for time off work, when they were really quite fit. This is a shame, since it tarnishes all true sufferers of back pain with the slur or malingerer. 
  I hope that you will find the information helpful, useful and practical. The information in this ebook on how to cure backache and related subjects is organized into 18 chapters of about 500-600 words each. 
  As an added bonus, I am granting you permission to use the content on your own website or in your own blogs and newsletter, although it is better if you rewrite them in your own words first.

  Chandogya Upanishad

  The word Upanishad (upa-ni-shad) consists of, "Upa" means "near;" "ni" means "down;" "shad" means "to sit." Thus, Upanishad is to sit down near the teacher to discuss, learn, practice, and experience. There are some 200 or more Upanishads. Some are lost and are only known about because of being referenced in other Upanishads. The Chandogya-upanishad belongs to the Sama-veda. It ranks among the oldest Upanishads, dating to the Brahmana period of Vedic Sanskrit (before the 8th century BC). It figures as number 9 in the Muktika canon of 108 Upanishads. It is part of the Chandogya Brahmana, which has ten Prapathakas (Parts). The first two Prapathakas of the Brahmana deal with sacrifices and other forms of worship. The other eight Prapathakas and their Khandas (Chapters) constitute the Chandogya Upanishad. The 11 principal Upanishads to which Sankara appeals in his great commentary on the Vedanta-Surtras are: Chandogya, Talavakara or Kena, Aitareya, Kaushitaki, Vajasaneyi or Isha, Katha, Mundaka, Taittirtiyaka or Taittiriya, Brihadaranyaka, Svetasvatara, and Prasna. They are also called the 11 classical Upanishads or the fundamental Upanishads of the Vedanta Philosophy. The Upanishadic literature is not a religious scripture and is free from dogma and doctrines. It is not a part of any religion but is a philosophy for all times and for all. German philosopher Arthur Schopenhauer, impressed by the Upanishads, called the texts "the production of the highest human wisdom". (Summary by Jothi)
