In Carrying the Fire, his account of his voyages into space and the years of training that led up to them, Collins reveals the human tensions, the physical realities, and the personal emotions surrounding the early years of the space race. Collins provides readers with an insider's view of the space program and conveys the excitement and wonder of his journey to the moon. As skilled at writing as he is at piloting a spacecraft, Collins explains the clash of personalities at NASA and technical aspects of flight with clear, engaging prose, withholding nothing in his candid assessments of fellow astronauts Neil Armstrong, John Glenn, and Buzz Aldrin, and officials within NASA. A fascinating memoir of mankind's greatest journey told in familiar, human terms, Carrying the Fire is by turns thrilling, humorous, and thought-provoking, a unique work by a remarkable man.

    Some system of authority is a requirement of all communal living, and it is only the man dwelling in isolation who is not forced to respond, through defiance or submission, to the commands of others. Obedience, as a determinant of behavior is of particular relevance to our time. It has been reliably established that from 1933 to 1945 millions of innocent people were systematically slaughtered on command. Gas chambers were built, death camps were guarded, daily quotas of corpses were produced with the same efficiency as the manufacture of appliances. These inhumane policies may have originated in the mind of a single person, but they could only have been carried out on a massive scale if a very large number of people obeyed orders.Obedience is the psychological mechanism that links individual action to political purpose. It is the dispositional cement that binds men to systems of authority. Facts of recent history and observation in daily life suggest that for many people obedience may be a deeply ingrained behavior tendency, indeed, a prepotent impulse overriding training in ethics, sympathy, and moral conduct. C. P. Snow (1961) points to its importance when he writes:When you think of the long and gloomy history of man, you will find more hideous crimes have been committed in the name of obedience than have ever been committed in the name of rebellion. If you doubt that, read William Sbirer's 'Rise and Fall of the Third Reich.' The German Officer Corps were brought up in the most rigorous code of obedience . . . in the name of obedience they were party to, andassisted in, the most wicked large scale actions in the history of the world. (p. 24)The Nazi extermination of European Jews is the most extremeinstance of abhorrent immoral acts carried out by thousands ofpeople in the name of obedience. Yet in lesser degree this type ofthing is constantly recurring: ordinary citizens are ordered todestroy other people, and they do so because they consider ittheir duty to obey orders. Thus, obedience to authority, longpraised as a virtue, takes on a new aspect when it serves amalevolent cause; far from appearing as a virtue, it is transformedinto a heinous sin. Or is it?The moral question of whether one should obey when commands conflict with conscience was argued by Plato, dramatized in "Antigone," and treated to philosophic analysis in every historical epoch Conservative philosophers argue that the very fabric of society is threatened by disobedience, and even when the act prescribed by an authority is an evil one, it is better to carry out the act than to wrench at the structure of authority. Hobbes stated further that an act so executed is in no sense the responsibility of the person who carries it out but only of the authority that orders it. But humanists argue for the primacy of individual conscience in such matters, insisting that the moral judgments of the individual must override authority when the two are in conflict.The legal and philosophic aspects of obedience are of enormous import, but an empirically grounded scientist eventually comes to the point where he wishes to move from abstract discourse to the careful observation of concrete instances. In order to take a close look at the act of obeying, I set up a simple experimentat Yale University. Eventually, the experiment was to involve more than a thousand participants and would be repeated at several universities, but at the beginning, the conception was simple. A person comes to a psychological laboratory and is told to carry out a series of acts that come increasingly into conflict with conscience. The main question is how far the participant will comply with the experimenter's instructions before refusing to carry out the actions required of him.But the reader needs to know a little more detail about the experiment. Two people come to a psychology laboratory to take part in a study of memory and learning. One of them is designated as a "teacher" and the other a "learner." The experimenter explains that the study is concerned with the effects of punishment on learning. The learner is conducted into a room, seated in a chair, his arms strapped to prevent excessive movement, and an electrode attached to his wrist. He is told that he is to learn a list of word pairs; whenever he makes an error, be will receive electric shocks of increasing intensity.The real focus of the experiment is the teacher. After watching the learner being strapped into place, he is taken into the main experimental room and seated before an impressive shock generator. Its main feature is a horizontal line of thirty switches, ranging from 15 volts to 450 volts, in 15-volt increments. There are also verbal designations which range from Slight SHOCK to Danger--Severe SHOCK. The teacher is told that he is to administer the learning test to the man in the other room. When the learner responds correctly, the teacher moves on to the next item; when the other man gives an incorrectanswer, the teacher is to give him an electric shock. He is to start at the lowest shock level ( 15 volts) and to increase the level each time the man makes an error, going through 30 volts, 45 volts, and so on.The "teacher" is a genuinely naive subject who has come to the laboratory to participate in an experiment. The learner, or victim, is an actor who actually receives no shock at all. The point of the experiment is to see how far a person will proceed in a concrete and measurable situation in which he is ordered to inflict increasing pain on a protesting victim.

    This volume highlights the research and findings of this natural scientist. Powerful modern microscopes have confirmed the accuracy of Haeckel's prints, which even in their day, became world famous. Haeckel's portfolio, first published between 1899 and 1904 in separate installments, is described in the opening essays. The plates illustrate Haeckel's fundamental monistic notion of the -unity of all living things- and the wide variety of forms are executed with utmost delicacy. Incipient microscopic organisms are juxtaposed with highly developed plants and animals. The pages, ordered according to geometric and -constructive- aspects, document the oness of the world in its most diversified forms. This collection of plates was not only well-received by scientists, but by artists and architects as well. Rene Binet, a pioneer of glass and iron constructions, Emile Galle, a renowned Art Nouveau designer, and the photographer Karl Blossfeld all make explicit reference to Haeckel in their work.

    Taylor, a theoretical physicist who has been one of the most inventive nuclear scientists of our time.Taylor was one of the most brilliant engineers of the nuclear age, but in his later years he became concerned with the possibility of an individual being able to construct a weapon of mass destruction on their own.

    Griffin marshals the evidence that cancer is a deficiency disease like scurvy or pellagra aggravated by the lack of an essential food compound in modem mans diet. That substance is vitamin B17. In its purified form developed for cancer therapy, it is known as Laetrile. It is the most complete and authoritative treatise ever produced on Laetrile. It explains the theory by which Laetrile is believed to work. Case histories are includedWhy has orthodox medicine waged war against this non drug approach? The author contends that the answer is to be found, not in science, but in politics and is based upon the hidden economic and power agenda of those who dominate the medical establishment.

    His writing is as much art as it is science. He is the most viable system I know." Dr Russell L Ackoff, The Institute for Interactive Management, Pennsylvania, USA. "If anyone can make it [Operations Research] understandably readable and positively interesting it is Stafford Beer everyone in management should be grateful to him for using clear and at times elegant English and even elegant diagrams." The Economist Based on the Massey Lectures, this book examines the reasons why the institutions of our society may well be failing, and opens a discussion as to what could be done. Drawing on the science of effective organization, which is his definition of cybernetics, Stafford Beer explains key cybernetic principles in words and pictures that all can understand. He concludes that our society commits more and more resources to plastering over the cracks in the system which simply reappear while freedom itself is increasingly eroded. The institutions must be redesigned, and returned to the people, to whom the scientific tools for doing this ought to belong.

    With an unrivaled grasp of his subject, Professor von Frisch unfolds the marvels of instinct and inventiveness among insects, fish, birds, and mammals. Much earlier than human technicians, termites created systems of air conditioning, dug wells to a depth of 120 feet, and built central cities with satellite suburbs. Wasps may have shown the Chinese how to make paper. Bowerbirds decorate their nests with the aesthetic sense of a painter. Animals have ingeniously used stone, wood, reeds, clay, and wax as building material. They have devised hinged doors, traps, shelters with overhanging roofs, cells with waterproof lining. The precision of their architecture frequently surpasses that of humans.Magnificently illustrated with 150 drawings and 132 photographs (84 in color), Animal Architecture is a book that will fascinate anyone interested in the world of nature.

    She plunges the reader into the Cetacea family with great, great power. Her contributors include leading scientists in whale brain studies, neurology, societal habits; Arctic naturalist Farley Mowatt & dolphinologist John Lilly; poets D.H. Lawrence, Pablo Neruda, Michael McClure etc.; & scholars of whale myths in world literatures. Brain analysis indicates that whales perceive in all their senses at once; i.e., where human motor controls are in varied areas of the brain, the whale's overlap & apparently are cross-stimulated, with results we can only imagine. Whales have very long lives (nobody knows for sure how long) & have been in the oceans for 30 million years. This extraordinary collection goes beyond any studies yet published & will appeal to a reader's imagination, intuition & heart, & should satisfy the scientific mind as well. Royalties from this thickly illustrated book will go to Project Jonah, a campaign for a world moratorium on the commercial killing of whales & dolphins.--Kirkus (edited)

    The conference was a gathering of specialists working in a wide variety of fields--astronomy, physics, radiophysics, computer science and technology, chemistry, biology, linguistics, archaeology, anthropology, sociology, and history--and included many scientists whose reputations are worldwide. For example, Freeman Dyson, Philip Morrison, and Charles Townes were among the American participants; their Russian counterparts were of comparable distinction. The conference was jointly organized by the U.S. National Academy of Sciences (with assistance from the U.S. National Science Foundation) and the U.S.S.R. Academy of Sciences. Scientists from several other countries also participated.Many aspects of the problem of extraterrestrial civilizations were discussed in detail, and these discussions are fully presented in this book. Particular attention is devoted to the following questions: the plurality of planetary systems in the universe, the origin of life on Earth, the possibility of life arising on cosmic bodies, the origin and evolution of intelligence, the origin and development of technological civilizations, problems in searching for intelligent signals or for evidence of astroengineering activities, and the problems and possible consequences of establishing contact with extraterrestrial civilizations.

    In The Curves of Life, Sir Theodore A. Cook (1867–1928), English author and editor, finds that the spiral or helix may lie at the core of life's first principle — that of growth. The spiral is fundamental to the structure of plants, shells, and the human body; to the periodicity of atomic elements and to an animal's horns; to microscopic DNA (the double helix) and to the Andromeda nebula.The Curves of Life portrays the significance of the spiral in 426 illustrations, from a Narwhal's tusk to Dürer's plan for a cylindrical helix. From the spiral in nature, science, and art, the author suggests ideas on the essence of beauty and man's response to it. "One of the chief beauties of the spiral as an imaginative conception is that it is always growing, yet never covering the same ground, so that it is not merely an explanation of the past, but is also a prophecy of the future."Martin Gardner, mathematician and author, said of The Curves of Life, "This is the classic reference on how the golden ratio applies to spirals and helices in nature."

    From the late 17th century until the end of the 19th, almost all educated people believed that the stars are suns surrounded by inhabited planets--a belief that was expressed not in science fiction, but in serious speculation, both scientific and religious, as well as in poetry. Only during the first half of the 20th century was it thought that life-bearing exoplanets planets are rare.This is not a science book--rather, it belongs to the category known as History of Ideas. First published by Atheneum in 1974, it tells the story of the rise, fall, and eventual renewal of widespread conviction that we are not alone in the universe. In this updated edition the chapters dealing with modern views have been revised to reflect the progress science has made during the past 40 years, including the actual detection of planets orbiting other stars.More poetry from past centuries, source notes, and an extensive bibliography have been added to this edition. In addition it contains a new Afterword, "Confronting the Universe in the Twenty-First Century," discussing the relevance of past upheavals in human thought to an understanding of the hiatus in space exploration that has followed the Apollo moon landings.From the published reviews:"Engdahl has marshalled an impressive and fascinating selection of primary sources--including a roster of believers that includes Newton, Ben Franklin, Walt Whitman, and rocket pioneer Robert Goddard; and . . . reminded us that our ancestors entertained a view of the universe that was larger and more imaginative than the history books lead us to believe. Challenging and original." --Kirkus Reviews"In a brisk, engrossing account Engdahl traces the theories and speculations concerning the possibility of extraterrestrial intelligent life throughout history. . . . This [book] is based on original research in primary sources and smoothly incorporates many quotations from scientists, philosophers, poets and theologians." --ALA Booklist"The Planet-Girded Suns is a beautiful example of what the disciplined imagination can do. . . . It is a fine, carefully done history of the ideas about other worlds--nicely balanced in its presentation of the informational and mystical elements of the subject." --Horn Book"The substantial treatment of the history of the idea of other solar systems, based largely on research in primary documents, should make it of use to scholars." --Isis One Hundred Second Critical Bibliography of the History of Science and Its Cultural Implications"Easy to read and on a timely subject approached from an original point of view, this also serves as a model to show how an idea is researched and documented." --School Library Journal"By carefully reconstructing her story from voluminous notes on many writers, both well-known and obscure, Engdahl has given vitality and dimension to the idea of extraterrestrial intelligence." --Cosmic Search"This is an important and interesting book. . . . The author's thought-provoking presentation on the subject should provide some fascinating reading." --National Space Society, 2012"Engdahl has crated a well-crafted, well-researched and unique view on exoplanets, and is a must-read for those who want a different view on space than the usual technical one." --Readers’ Favorites, 2012

    We cannot really comprehend what it means to say that a galaxy is exploding, yet that is the nature of some of the distant radio sources in the furthest reaches of space. Closer to home, in the Milky Way galaxy, radio astronomers listen patiently to the ticking of pulsars that tell of star death and states of matter of awesome densities. And between the stars, radio emission from a host of over 120 complex molecules radiate outward to reveal a tale about chemical processes that produce the very stuff of life. And all of this happens out there in the universe hidden from our eyes, even when aided by the Hubble Space Telescope.This is the story of radio astronomy, of how radio waves are generated by stars, supernova, quasars, colliding galaxies, and by the very beginnings of the universe itself. In The Invisible Universe, you learn what astronomers are doing with those huge dishes in the New Mexico desert, in a remote valley in Puerto Rico, in the green Pocahontas Valley in West Virginia, as well as dozens of other remote sites around the world. With each of these observatories, the scientists collect and analyze their data, "listening" to the radio signals from space, in order to learn what is out there, and perhaps even if someone else may be listening as well.From the reviews of the first edition -"All in all, it's a grand and glorious story and Verschuur tells it with panache. The illustrations are superb, up to date, well done, and most of them are unfamiliar . . . Radio photos of Cygnus A and Cassiopeia A are wonderful . . . the book is strong in stressing the human aspects of astronomy . . . a good summary of what the radio universe contains and an interesting perspective on our understanding of it."" Astronomy"Every college and public library, and many high school libraries, should acquire a copy of this one-of-a-kind work by a radio astronomer who has shaped the field." 21st Century" . . . a thoroughly up-to-date account of the radio sky . . . lavishly illustrated with dramatic images . . . very complete and readable." Sky and Telescope"Verschuur's contribution will [also] be enjoyed by his scientific colleagues; we can also commend it to the the Councils of our funding agencies and to those who regulate the use of the radio spectrum." Journal of the British Astronomical Association"This is a most fascinating book . . . a book where the text is a pleasure to read and the illustrations . . . of the highest quality." Space Science Reviews

    Of the four books published in English during his lifetime, it is the only one to include contributions from his three primary areas of achievement: philosophical reflection on gnosticism, on biology, and on technology - hence the subtitle, "From Ancient Creed to Technological Man." The three sections of the book are, however, given in reverse order with essays on "Science, Technology, and Ethics" preceding papers on "Organism, Mind, and History" and "Religious Thought of the First Christian Centuries." The temporally ultimate project is that which Jonas sees as having philosophical priority. This collection of 18 essays originally published between 1965 and 1974 - that is, after completion of The Phenomenon of Life (1966) but before The Imperative of Responsibility (1984) - manifests the most intensive integration of Jonas's three projects. As such, this volume provides special witness to the inherent unity of what might otherwise be seen as more episodic work. In the Introduction Jonas himself argues for both a biographical and a philosophical unity, the latter of which is emphasized in a new foreword by Carl Mitcham of the European Graduate School.

    A brief introduction to the history and characteristics of prehistoric mammals in general, and specific descriptions of twelve different kinds.

    During this period bacteria which cause disease and death were identified and soon cures or vaccines against them were developed. Medicine was revolutionised. Many men of prodigious talent took part in this momentous transformation. The story shifts from country to country - from Jenner's rural practice in England to Pasteur's laboratories in the breweries and silk farms of France, and on to Koch's surgery in Prussia. It is a narrative as exciting as any novel. But it is more than just that. Robert Reid is able to use the germ theory as a case-study in the methods and responsibilities of scientists. A great discovery may turn out to be a double-edged sword, yet the process of discovering ways to control nature must go on if a world saved from disease is not to see, instead, men dying of starvation.
