Technology, she writes, catalyzes changes not only in what we do but in how we think. First published in 1984, The Second Self is still essential reading as a primer in the psychology of computation. This twentieth anniversary edition allows us to reconsider two decades of computer culture--to (re)experience what was and is most novel in our new media culture and to view our own contemporary relationship with technology with fresh eyes. Turkle frames this classic work with a new introduction, a new epilogue, and extensive notes added to the original text.Turkle talks to children, college students, engineers, AI scientists, hackers, and personal computer owners--people confronting machines that seem to think and at the same time suggest a new way for us to think--about human thought, emotion, memory, and understanding. Her interviews reveal that we experience computers as being on the border between inanimate and animate, as both an extension of the self and part of the external world. Their special place betwixt and between traditional categories is part of what makes them compelling and evocative. (In the introduction to this edition, Turkle quotes a PDA user as saying, When my Palm crashed, it was like a death. I thought I had lost my mind.) Why we think of the workings of a machine in psychological terms--how this happens, and what it means for all of us--is the ever more timely subject of The Second Self.

    In addition to fieldwork and traditional methods, paleoanthropologists and archaeologists now draw upon genetics and other cutting-edge scientific techniques. In fifty chapters, Prehistoric Investigations tells the story of the many thought-provoking discoveries that have transformed our understanding of the distant past.

    1: Elementary Theory and Problems contains the essential material that is usually covered in required courses of strength of materials in our engineering schools. Strength of Materials - Part. 2: Advanced Theory and Problems contains the later developments that are of practical importance in the fields of strength of materials, and theory of elasticity. Complete derivations of problems of practical interest are given in most cases. The books are illustrated with a number of problems to which solutions are presented. In many cases, the problems are chosen so as to widen the field covered by the text and to illustrate the application of the theory in the solution of design problems.

    In an era when rogue nations like North Korean and Iran strive to create their own precarious weapons programs, Younger’s The Bomb provides much-needed background and insight for students, policy makers, and readers who wish to better understand the important issues involving nuclear weapons and national security.

    Fearlessly pondering life’s end, Holloway examines how doubts too often paralyze people. He explains, “A sentence is not finished till it has a full stop, and every life needs a dying to complete it … Our brief finitude is but a beautiful spark in the vast darkness of space. So we should live the fleeting day with passion and, when the night comes, depart from it with grace.” Written in the context of organized religion’s structural difficulties, Looking in the Distance is a highly personal and meditative work that helps us better understand the myriad ways in which the human search for wholeness and healing can be approached. Accessible, funny, inquisitive and ever hopeful, it will inspire all who read it.

    "A masterpiece of science."—Werner von Braun.

    In the wake of discoveries through the telescope and Copernican theory, the notion of an ordered cosmos of "fixed stars" gave way to that of a universe infinite in both time and space—with significant and far-reaching consequences for human thought. Alexandre Koyré interprets this revolution in terms of the change that occurred in our conception of the universe and our place in it and shows the primacy of this change in the development of the modern world.

    The author of "Ancient Philosophy, Mystery and Magic" has unearthed a sensational, true story of a mystical and esoteric tradition that lies hidden at the roots of Western culture--and that gave rise to the world we live in.

    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 siecle 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.

    Bernard Haisch contends that there is a purpose and an underlying intelligence behind the Universe, one that is consistent with modern science, especially the Big Bang and evolution. It is based on recent discoveries that there are numerous coincidences and fine-tunings of the laws of nature that seem extraordinarily unlikely.A more rational concept of God is called for. As astrophysicist Sir James Jeans wrote, "the Universe begins to look more like a great thought than like a great machine."Despite bestsellers by Christopher Hitchens, Richard Dawkins, and Sam Harris that have denounced the evils of religion and proclaimed that science has shown that there is no God, The Purpose-Guided Universe shows how one can believe in God and science.

    A concise look at the impact of the advent of the telescope on the way humans view the universe and their place in it focuses on the visionaries, beginning with Galileo, who created and perfected it.
