  Sleep Sounds 3 Fall Asleep...

  This Audiobook gives you a bundle of two 12 hour programs. 
  The programs begin after a short narration of guided imagery to prepare you for sleep. 
  Program One: 12 hours of the sounds of a Cascading Waterfall and the Soothing Tones of Calming Classical Music. 
  Program Two: 12 hours of just the sounds of a Cascading Waterfall without the classical music. 
  The musical tones are serene arrangements of the most-loved, composers: Bach, Beethoven, Chopin, Debussy, Mozart, Pachelbel, Rachmaninoff, Tchaikovsky and more. 
  The producer of the audiobook is an award-winning sound designer and composer. When he and his wife struggled with sleep apnea, he searched for an audio program that would help. "I mostly found cheap sound effects with repetitive, looping tones. Granted, my background makes me a little picky, but I found these programs more annoying than relaxing." 
  So he set out to record the best sounds he could find. The ocean waves, rain, thunder, streams and waterfalls are all original recordings. 
  Next, he experimented with tones. This program is the first to include arrangements of beautiful classical music. "I have produced over twenty experimental programs now and have had sleep doctors, patients, as well as my own friends and family members try them on. This current series of “Sleep Sounds" has been very well received and has been proven to be the most effective by the largest number of people."

  Waiting for Aphrodite - Journeys...

  "We humans are a minority of giants, stumbling around in the world of little things," Sue Hubbell writes in this marvelous book. Each of these little things "has a complicated and special way of getting on in the world, different from ours and different from one another's." 
    
  In Waiting for Aphrodite she explores the ways of sponges and sea urchins, horseshoe crabs and the sea mouse known as Aphrodite—as well as our ways. She takes us on a journey through the mysteries of time—geological, biological, and personal—as she writes of the evolution of life on this planet and the evolution of her own life: her childhood next to a Michigan graveyard; the three colleges where she "learned three things"; her twenty-five years keeping bees on a farm in the Ozarks; her move to a "strange little house" in a small Maine town, "the place I wanted to grow old in." And in the tide pools and ocean waters there she discovered a whole new world, the world of little things that inspired this book. 
    
  "In her new book, Hubbell becomes a Shakespeare of advocacy for some of the more ignored denizens of our complicated planet."—Newsday

  Biocivilisations - A New Look at...

  Biocivilisations is an important, original rethinking of the mystery of life and its deep uncertainty, exploring the complex civilisations that existed on Earth long before humans.  
  What is life? Many scientists believe life can be reduced to ‘mechanistic’ factors, such as genes and information codes. Yet there is a growing army of scientists, philosophers and artists who reject this view. The gene metaphor is not only too simplistic but deeply misleading. If there is a way to reduce life to a single principle, that principle must acknowledge the creativity of life, turning genetic determinism on its head.  
  The term biocivilisations is the acknowledgement of this uncertainty of life, as opposed to a quasi-certainty of the human position governed by a narrow time window of the scientific revolution. Life existed without humans for more than 99.99 percent of the Earth’s existence. Life will also continue without humans long after our inevitable extinction.  
  In Biocivilisations, Dr Predrag Slijep?evi? shows how bacteria, amoebas, plants, insects, birds, whales, elephants and countless other species not only preceded human beings but demonstrate elements of how we celebrate human civilisation – complex communication, agriculture, science, art, medicine and more.  
  Humans must try to adopt this wisdom from other biocivilisations that have long preceded our own. By rethinking the current scientific paradigm, Dr Slijep?evi? makes clear that a transformation – from a naïve young species into a more mature species in tune with its surroundings – will save us from our own violence and the violence we inflict on the rest of our living planet.

  Number Theory

  In old times, number theory was also known as arithmetic. However, now arithmetic and number theory are considered as separate branches from each other’s, it was not same in old times. Number theory is one of the many important branches of pure mathematics. This branch is mainly dedicated and includes study about integers. This theory describes many fundamental and basic concepts of mathematics that were used to develop modern concepts. Thus, number theory is often referred as “Queen of Mathematics”. In number theory, following concepts are described:Concept of prime numbersProperties of objects that are derived through integersGeneralization of integers 
  Rational numbers and algebraic integers are significant concepts that are included in number theory. In number theory, integers are considered as a solution to a particular problem. This concept is known as Riemann Zeta Function. However, it is not necessary to consider them as solution only; they can also be considered in themselves. Study of analytical objects helps to understand questions in number theory. Properties of integers, prime numbers and number-theoretic objects are described in Riemann Zeta Function. These properties can be studied descriptively in a separated branch named analytic number theory. In Diophantine approximation, real numbers are learnt in ration to relational number. 
  In older terms, arithmetic was used to refer number theory. However, it was separated in early 20th century. Arithmetic word is now used to refer to general elementary calculations. Term arithmetic is now used in many fields such as:Mathematical logicPeano arithmeticComputer scienceFloating point arithmetic 
  In late 20th century, French theorists leaved a noticeable impact on number theory. Due to their influence, they again related tern arithmetic with number theory. However, many theorists argued upon this and denied to accept this as it was already proven false in past time. However, term arithmetical is now considered as adjective to number-theoretic. Early 20th century was a golden time for development of number theory, especially the time span of 1930s and 1940s. Many important results were acquired in that period. Later on, 1970s was proven an important period as well with the development of computational complexity theory. 
  Number theory is an important branch of pure mathematics since it contains many basic concepts that are used to build up complex concepts of pure mathematics. One who is looking for a breakthrough in broad term mathematics is suggested to start from this theory. It will clear up basic concepts so it will be surprisingly easy to understand complex concepts. This short book describes all the basic concepts without going in too deep. So, one can use this basic knowledge to understand complex concepts easily and effectively.

  US Army 1960s Polygraph Training

  The primary mission of military intelligence in the United States Army is to provide timely, relevant, accurate, and synchronized intelligence and electronic warfare support to tactical, operational and strategic-level commanders. The Army’s intelligence components produce intelligence both for Army use and for sharing across the national intelligence community. The military will subject someone to a polygraph for several reasons: If that person needs to access confidential files; if they are accused of leaking government secrets; if they are accused of terrorism or of being a spy; if they are a foreign national who needs access to classified material, and several other reasons. The following is a 1960s Army training recording with information on administering a lie detector test.
