    Each object is plotted on a detailed, easy-to-use star map, and most of these sights can be found even in a light-polluted sky. Also included are four seasonal all-sky charts that help locate each highlight. You don't need fancy or expensive equipment to enjoy the wonders of the night sky. In fact, as even experienced star gazers know, to go beyond the naked-eye sky and delve deep into the universe, all you need are binoculars ? even the ones hanging unused in your closet. If you don't own any, Binocular Highlights explains what to look for when choosing binoculars for star gazing and provides observing tips for users of these portable and versatile mini-telescopes. Sprial-bound with readable paper spine, full color throughout.

    It was studied from antiquity to the Renaissance as a way of glimpsing the nature of reality. Geometry is number in space; music is number in time; and comology expresses number in space and time. Number, music, and geometry are metaphysical truths: life across the universe investigates them; they foreshadow the physical sciences.Quadrivium is the first volume to bring together these four subjects in many hundreds of years. Composed of six successful titles in the Wooden Books series-Sacred Geometry, Sacred Number, Harmonograph, The Elements of Music, Platonic & Archimedean Solids, and A Little Book of Coincidence-it makes ancient wisdom and its astonishing interconnectedness accessible to us today.Beautifully produced in six different colors of ink, Quadrivium will appeal to anyone interested in mathematics, music, astronomy, and how the universe works.

    Can you believe that physical reality is created by our observation of it? Physicists were forced to this conclusion, the quantum enigma, by what they observed in their laboratories.Trying to understand the atom, physicists built quantum mechanics and found, to their embarrassment, that their theory intimately connects consciousness with the physical world. Quantum Enigma explores what that implies and why some founders of the theory became the foremost objectors to it. Schr�dinger showed that it absurdly allowed a cat to be in a superposition simultaneously dead and alive. Einstein derided the theory's spooky interactions. With Bell's Theorem, we now know Schr�dinger's superpositions and Einstein's spooky interactions indeed exist.Authors Bruce Rosenblum and Fred Kuttner explain all of this in non-technical terms with help from some fanciful stories and bits about the theory's developers. They present the quantum mystery honestly, with an emphasis on what is and what is not speculation.Physics' encounter with consciousness is its skeleton in the closet. Because the authors open the closet and examine the skeleton, theirs is a controversial book. Quantum Enigma's description of the experimental quantum facts, and the quantum theory explaining them, is undisputed. Interpreting what it all means, however, is controversial.Every interpretation of quantum physics encounters consciousness. Rosenblum and Kuttner therefore turn to exploring consciousness itself--and encounter quantum physics. Free will and anthropic principles become crucial issues, and the connection of consciousness with the cosmos suggested by some leading quantum cosmologists is mind-blowing.Readers are brought to a boundary where the particular expertise of physicists is no longer a sure guide. They will find, instead, the facts and hints provided by quantum mechanics and the ability to speculate for themselves.

    This book offers the opportunity to truly comprehend the workings of one of humanity's greatest minds. Acclaimed by Einstein himself, it is among the clearest, most readable expositions of relativity theory. It explains the problems Einstein faced, the experiments that led to his theories, and what his findings reveal about the forces that govern the universe. The concepts of relativity and the fourth dimension unfold with all the vivid excitement of research into the unknown, in language anyone can readily understand.

    Extracted from opium, the sap of the poppy, this popular drug was welcomed into the homes of rich and poor alike, in the guise of medicinal uses in the form of laudanum and opium elixirs, and as pure, undisguised morphine.Laudanum contained opium, saffron, cinnamon and alcohol. In the spirit of 19th century progress, other opium concoctions were created and a whole industry in quackery erupted. In both Britain and North America, opium was mixed with everything imaginable: mercury, hashish, cayenne pepper, ether, chloroform, belladonna and whisky, sherry, wine and brandy.In the Arms of Morpheus examines how the drinking of laudanum for medical reasons developed and how it became an everyday safeguard against pain, poverty, and boredom. Opium eating was catapulted into fame by the confessions of Thomas De Quincy and insinuated itself into the lives and works of writers such as Louisa May Alcott, Lord Byron, Shelley, Elizabeth Barrett Browning, John Keats, the Brontes, Samuel Taylor Coleridge and many others.Thoroughly researched and copiously illustrated with photographs, engravings, advertisements, movie stills, pulp magazine and dime novel covers and paraphernalia, In the Arms of Morpheus continues the history of opium's emergence as an omnipresent and sometimes devastating influence.

    Astronomy: A Beginner's Guide to the Universe.

    Now Lost Star of Myth and Time shows evidence the Ancients were not just weaving fanciful tales - science is on the verge of an amazing discovery - our Sun has a companion star carrying us through a great cycle of stellar influences. If true, it means the Ancients were right and our views of space and time and the history of civilization will never be the same. More than that, it would mean we are now at the dawn of a new age in human development and world conditions.

    The book traces the history of astronomy, from the earliest human civilizations to the present day, plus a description of what the interested person can see in the night sky.

    astronomers, and Aristotle. G. E. R. Lloyd also investigates the relationships between science and philosophy and science and medicine; he discusses the social and economic setting of early Greek science; and he analyzes the motives and incentives of the different groups of writers.

    Attracting hundreds of thousands of readers and stimulating vast debate, it influenced generations of people including countless scientists who went on to do serious work in their fields, and numerous science-fiction writers. It is a measure of the power of the Atlantis myth that, despite all the evidence to the contrary, the idea of a submerged Atlantic Ocean continent remains vigorous today, long after Donnelly's work first appeared.A lawyer and politician before he turned to writing, Ignatius Donnelly (1831‒1901) spent many years amassing evidence for his book on Atlantis. Displaying an immense knowledge of Platonic and Biblical material, comparative archeological discoveries, folk traditions of deluges, and geological data supporting catastrophic volcanic activity, Donnelly staggered his readers with "facts" and overwhelmed them with his many brilliant arguments. Despite the many more recent discoveries that have proved many of his "facts" to be false, his arguments still dazzle and his central myth continues to fascinate. The highly appealing idea of a lost continent with a high civilization, one that was the mother of all other civilizations, is one of the most enduring of all human myths and shows no signs of disappearing.A seminal work on Atlantis and a classic in the history of culture, this book is the starting point for anyone sincerely interested in the Atlantis myth. Still the most readable and imaginative of the books on Atlantis, it is a work that will long outlive most of the more recent accounts. As a study of the golden past, it is an enormously intriguing and enjoyable book.

    Inspired by and expanding on a series of lectures presented by Leonard Peikoff, David Harriman presents a fascinating answer to the problem of induction-the epistemological question of how we can know the truth of inductive generalizations.Ayn Rand presented her revolutionary theory of concepts in her book Introduction to Objectivist Epistemology. As Dr. Peikoff subsequently explored the concept of induction, he sought out David Harriman, a physicist who had taught philosophy, for his expert knowledge of the scientific discovery process.Here, Harriman presents the result of a collaboration between scientist and philosopher. Beginning with a detailed discussion of the role of mathematics and experimentation in validating generalizations in physics-looking closely at the reasoning of scientists such as Galileo, Kepler, Newton, Lavoisier, and Maxwell-Harriman skillfully argues that the inductive method used in philosophy is in principle indistinguishable from the method used in physics.

    Volume 1 looks at the discipline's origins in Babylon and Egypt, the creation of geometry and trigonometry by the Greeks, and the role of mathematics in the medieval and early modern periods.
