Examines recent scientific discoveries that suggest there may be other life forms in the universe

"Robert Zubrin is a true engineering genius like the heroic engineers of the past." -- Frederick Turner, American Enterprise Using nuts-and-bolts engineering and a unique grasp of human history, Robert Zubrin takes us to the not-very-distant future, when our global society will branch out into the universe. From the current-day prospect of lunar bases and Mars settlements to the outer reaches of other galaxies, Zubrin delivers the most important and forward-looking work on space and the true possibilities of human exploration since Carl Sagan's Cosmos. Sagan himself said of Zubrin's humans-to-Mars plan, " Bob Zubrin really, nearly alone, changed our thinking on this issue." With Entering Space , he takes us further, into the prospect of human expansion to the outer planets of our own solar system--and beyond.

"Here is the story of how two people most influenced Feynman's early years-his father, who taught him to think, and his first wife Arlene who taught him to love, even as she lay dying in an Albuquerque hospital while Feynman worked nearby, on the atomic bomb at Los Alamos. And here are lighter moments, some told through letters, as Feynman reports from Geneva, Trinidad, Greece, and Japan on the effects this curious character has had on the locals. The second half of the book...is Feynman's behind-the-scenes account of the investigation that followed the space shuttle Challenger's explosion in January 1986"--Jacket.

This invaluable book presents most of the important papers of Emil Wolf, published over half-a-century. It covers chiefly diffraction theory (especially the analysis of the focal region), the theory of direct and inverse scattering, phase-space methods in quantum mechanics, the foundation of radiometry, phase conjugation and coherence theory. Several papers which have become classics of the optical literature are included, such as those on Wolf's rigorous formulation of the theory of partial coherence and partial polarization, the introduction of diffraction tomography, and his discovery of correlation-induced shifts of spectral lines (often called the Wolf effect). There are also papers dealing with the historical development of optics and some review articles.

In the spring of 1919, two British solar eclipse expeditions confirmed the correctness of general relativity theory and propelled Albert Einstein to instant celebrity. Before this major turning point, the majority of Einstein's writings published in this volume dealt with the clarification of general relativistic problems, such as the status of the metric field, the character of gravitational waves, the problem of energy-momentum conservation, and questions of cosmology, such as the nature and size of the universe and the distribution of matter within it. After his rise to international fame, Einstein's publications changed markedly. He faced an increasing demand for popular articles and lectures on relativity, its development and meaning. He also felt compelled to respond to a host of commentators, ranging from skeptical physicists to philosophers trying to reconcile his revolutionary theory with their views. For the first time, he also responded in print to outspoken anti-relativists, some of them fueled by cultural conservatism and, frequently, anti-Semitism. Einstein used his newly won fame to lend prestige to political causes, especially to the reconciliation among European nations and to Zionism. In the early years of Weimar Germany, Einstein spoke out vigorously for the young republic, emphasizing the rights of the individual. He agonized over the misery of the Central Europeans in the grip of starvation and economic collapse, praised the support of individuals and groups such as the Quakers, and championed the cause of Eastern European Jews. His rejection of assimilation, combined with a fierce defense of the right of Jews to higher education, led Einstein to campaign for the establishment of a university in Palestine, the land which he conceived of as a cultural center for all Jews.

Bohm presents the theory of relativity as a unified whole, making clear the reasons which led to its adoption and explaining its basic meaning. He also reveals the limited truth of some of the assumptions which stop us appreciating it.

Endeavors to explain Einstein's general theory of relativity, beginning with the equivalence principle and covering the necessary mathematics of Riemannian spaces and tensor calculus, offering readers a deeper understanding of the universe's real structure.

"If you really want to understand human nature, you must observe people as they are before they are corrupted by language and culture, by MTV and Hebrew school. You must look at babies." So contends psychologist Paul Bloom-whom Steven Pinker calls "the wunderkind of cognitive science"-in this fascinating account of how we learn to make sense of reality. All humans see the world in two fundamentally different ways: Even babies have a rich understanding of both the physical and social worlds. They expect objects to obey principles of physics, and they're startled when things disappear or defy gravity. Yet they can also read emotions and respond with anger, sympathy, and joy.In Descartes' Baby, Bloom draws on a wealth of scientific discoveries to show how these two ways of knowing give rise to such uniquely human traits as humor, disgust, religion, art, and morality. The myriad ways that our dualist perspectives, born in infancy, undergo development throughout our lives and profoundly influence our thoughts, feelings, and actions is the subject of this richly rewarding book.

Perhaps the greatest physicist of the second half of the twentieth century, Richard Feynman changed the way we think about quantum mechanics, the most perplexing of all physical theories. Here the author, himself a theoretical physicist, offers a scientific biography: a narrative coupled with clear and novel expositions of science at the limits. An immensely colorful persona in and out of the office, Feynman revolutionized our understanding of nature amid a turbulent life. The author presents that life, from the death of Feynman's childhood sweetheart during the Manhattan Project to his reluctant rise as a scientific icon, seen through the science, providing a new understanding of the legacy of a man who has fascinated millions. A reflection on the issues that drive physics today, this work captures the story of a man who was willing to break all the rules to tame a theory that broke all the rules.

In this original study, noted scholar and theologian David Hartman discusses the relation between Maimonides’ halakhic writings and The Guide of the Perplexed—the connection is much closer than is generally supposed. Maimonides: Torah and Philosophic Quest demonstrates that Maimonides’ total philosophic endeavor was an attempt to show how the free search for truth, established through the study of logic, physics, and metaphysics, can live harmoniously with a way of life defined by the normative traditions of Judaism.

For David Deutsch, a young physicist of unusual originality, quantum theory contains our most fundamental knowledge of the physical world. Taken literally, it implies that there are many universes “parallel” to the one we see around us. This multiplicity of universes, according to Deutsch, turns out to be the key to achieving a new worldview, one which synthesizes the theories of evolution, computation, and knowledge with quantum physics. Considered jointly, these four strands of explanation reveal a unified fabric of reality that is both objective and comprehensible, the subject of this daring, challenging book. The Fabric of Reality explains and connects many topics at the leading edge of current research and thinking, such as quantum computers (which work by effectively collaborating with their counterparts in other universes), the physics of time travel, the comprehensibility of nature and the physical limits of virtual reality, the significance of human life, and the ultimate fate of the universe. Here, for scientist and layperson alike, for philosopher, science-fiction reader, biologist, and computer expert, is a startlingly complete and rational synthesis of disciplines, and a new, optimistic message about existence.
