With clear explanations of some of the most complex scientific endeavors in history, Mahaffey's new book looks back at the atom's wild, secretive past and then toward its potentially bright future.Mahaffey unearths lost reactors on far flung Pacific islands and trees that were exposed to active fission that changed gender or bloomed in the dead of winter. He explains why we have nuclear submarines but not nuclear aircraft and why cold fusion doesn't exist. And who knew that radiation counting was once a fashionable trend? Though parts of the nuclear history might seem like a fiction mash-up, where cowboys somehow got a hold of a reactor, Mahaffey's vivid prose holds the reader in thrall of the infectious energy of scientific curiosity and ingenuity that may one day hold the key to solving our energy crisis or sending us to Mars.

    

    It is the way of direct experience of Truth. It is the way of the heart.It may be astonishing to hear that there is a continuation of A Course in Miracles, but it is true. Forty years ago Jesus dictated ACIM to the scribe Helen Schucman. More recently, over three years, he similarly dictated A Course of Love to Mari Perron. Students of ACIM will recognize the Voice. Students of truth, whatever their background, will find that ACOL resonates with the heart.In A Course of Love Jesus says: "This time we take a direct approach, an approach that seems at first to leave behind abstract learning and the complex mechanisms of the mind that so betray you. We take a step away from intellect, the pride of the ego, and approach this final learning through the realm of the heart. This is why, to end confusion, we call this course A Course of Love." (Prelude.44)ACIM and ACOL are complementary. The same Voice, more accessible. The same thought system, expanded.Like all non-dual teachings, ACOL is not about adding to one s life but about un-doing the ties that bind us to what it calls the "house of illusion." In ACOL we are gently guided to awaken, step by loving step. We find ourselves in the unlimited, eternal field of our own awareness, laughing and crying at the glory of what is.

    With this concise book, you will quickly gain working knowledge of Sinatra and its minimalist approach to building both standalone and modular web applications. Sinatra serves as a lightweight wrapper around Rack middleware, with syntax that maps closely to functions exposed by HTTP verbs, which makes it ideal for web services and APIs. If you have experience building applications with Ruby, you’ll quickly learn language fundamentals and see under-the-hood techniques, with the help of several practical examples. Then you’ll get hands-on experience with Sinatra by building your own blog engine. Learn Sinatra’s core concepts, and get started by building a simple application Create views, manage sessions, and work with Sinatra route definitions Become familiar with the language’s internals, and take a closer look at Rack Use different subclass methods for building flexible and robust architectures Put Sinatra to work: build a blog that takes advantage of service hooks provided by the GitHub API

    Barry's set of experiences with these legends of humour is unique, and will delight all who made PIGS CAN FLY a runaway porcine bestseller. In this completely new, organically grown book, old Baz recalls, reminisces, recounts and other words beginning with 'R', on a trip down Memory Lane, pausing only for tea and macaroons at the Stannah Stairlift Cafe. What memories - if only he can remember them. Currently 74, a third of his life has already passed and he invites you to enjoy this wonderfully funny account of it, a decorous orgy of nostalgia.

    In this spirit, the team at NASA set about developing the Space Shuttle, arguably the most complex piece of machinery ever created. The world’s first reusable spacecraft, it launched like a rocket, landed like a glider, and carried out complicated missions in between.  Bold They Rise tells the story of the Space Shuttle through the personal experiences of the astronauts, engineers, and scientists who made it happen—in space and on the ground, from the days of research and design through the heroic accomplishments of the program to the tragic last minutes of the Challenger disaster. In the participants’ own voices, we learn what so few are privy to: what it was like to create a new form of spacecraft, to risk one’s life testing that craft, to float freely in the vacuum of space as a one-man satellite, to witness a friend’s death. A “guided tour” of the Shuttle—in historical, scientific, and personal terms—this book provides a fascinating, richly informed, and deeply personal view of a feat without parallel in the human story.

    Astronomy: A Beginner's Guide to the Universe.

    His controversial contention is that the Universe itself can be regarded as a living entity which, rather than being unique, has evolved through Darwinian selection among a multitude of rival universes, competing for existence in spacetime. This vision of the Universe as a product of evolution by natural selection echoes and extends the idea that all the living things on Earth may form an interlocking web which can be regarded as a single living organism, Gaia. On scales intermediate between that of a single planet and that of the entire Universe, whole galaxies of stars, like our Milky Way system, also show properties usually associated with living systems, and evidence of evolution. Along the way we learn why the laws of physics should be as they are, and whether human beings have a special place in the living Universe. In the Beginning is Dr Gribbin’s tour de force – science writing at its best. Praise for John Gribbin: ‘One of the finest and most prolific writers of popular science around’ – The Spectator John Gribbin is an award-winning science writer best known for his book In Search of Schrodinger's Cat. He studied astrophysics under Fred Hoyle in Cambridge, before working as a science journalist for Nature and later the New Scientist, and is now a Visiting Fellow in Astronomy at the University of Sussex.

    Belknap's Waterproof Grand Canyon River Guide (All New Color Edition)

    Assuming no prior knowledge of C, this introductory-level book demonstrates and explains how to write useful and marketable programs in Turbo C on the IBM PC, XT, AT, and PC/Z computers.

    This discovery dramatically reshaped how humans understood their place in the cosmos, and once and for all laid to rest the idea that the Milky Way galaxy was alone in the universe. Six years later, continuing research by Hubble and others forced Albert Einstein to renounce his own cosmic model and finally accept the astonishing fact that the universe was not immobile but instead expanding. The fascinating story of these interwoven discoveries includes battles of will, clever insights, and wrong turns made by the early investigators in this great twentieth-century pursuit. It is a story of science in the making that shows how these discoveries were not the work of a lone genius but the combined efforts of many talented scientists and researchers toiling away behind the scenes. The intriguing characters include Henrietta Leavitt, who discovered the means to measure the vast dimensions of the cosmos . . . Vesto Slipher, the first and unheralded discoverer of the universe’s expansion . . . Georges Lemaître, the Jesuit priest who correctly interpreted Einstein’s theories in relation to the universe . . . Milton Humason, who, with only an eighth-grade education, became a world-renowned expert on galaxy motions . . . and Harlow Shapley, Hubble’s nemesis, whose flawed vision of the universe delayed the discovery of its true nature and startling size for more than a decade.Here is a watershed moment in the history of astronomy, brought about by the exceptional combination of human curiosity, intelligence, and enterprise, and vividly told by acclaimed science writer Marcia Bartusiak.
