Half a century later, only robots have been to the Red Planet and our astronauts rarely venture beyond Earth orbit.Now Mars is back With everyone from Elon Musk to Ridley Scott and Donald Trump talking about it, interplanetary exploration is back on the agenda and Mars is once again the prime destination for future human expansion and colonisation. In Destination Mars, astrophysicist and science writer Andrew May traces the history of our fascination with the Red Planet and explores the science upon which a crewed mission would be based, from assembling a spacecraft in Earth orbit to surviving solar storms. With expert insight, he analyses the new space race and assesses what the future holds for human life on Mars.

    Counterfactuals is David Lewis' forceful presentation of and sustained argument for a particular view about propositions which express contrary to fact conditionals, including his famous defense of realism about possible worlds.

    Whether they've arrived via rocket, flying saucer, or plain old teleportation, they've been invading, infiltrating, or inspiring us for decades, and they've fascinated moviegoers and television watchers for more than fifty years. About half of us believe that aliens really exist, and millions are convinced they've visited Earth. For twenty-five years, SETI has been looking for the proof, and as the program's senior astronomer, Seth Shostak explains in this engrossing book, it's entirely possible that before long conclusive evidence will be found. His informative, entertaining report offers an insider's view of what we might realistically expect to discover light-years away among the stars. Neither humanoids nor monsters, says Shostak; in fact, biological intelligence is probably just a precursor to machine beings, enormously advanced artificial sentients whose capabilities and accomplishments may have developed over billions of years and far exceed our own. As he explores what, if anything, they would tell us and what their existence would portend for humankind and the cosmos, he introduces a colorful cast of characters and provides a vivid, state-of-the-art account of the past, present, and future of our search for extraterrestrial intelligence.

    In Gravity, he takes an enlightening look at three of the towering figures of science who unlocked many of the mysteries behind the laws of physics: Galileo, the first to take a close look at the process of free and restricted fall; Newton, originator of the concept of gravity as a universal force; and Einstein, who proposed that gravity is no more than the curvature of the four-dimensional space-time continuum.Graced with the author's own drawings, both technical and fanciful, this remarkably reader-friendly book focuses particularly on Newton, who developed the mathematical system known today as the differential and integral calculus. Readers averse to equations can skip the discussion of the elementary principles of calculus and still achieve a highly satisfactory grasp of a fascinating subject.Starting with a chapter on Galileo’s pioneering work, this volume devotes six chapters to Newton's ideas and other subsequent developments and one chapter to Einstein, with a concluding chapter on post-Einsteinian speculations concerning the relationship between gravity and other physical phenomena, such as electromagnetic fields.

    His simple but staggering theory of quantum evolution shows how quantum mechanics gives living organisms the ability to initiate specific actions, including new mutations. As Paul Davies exclaims, "if these ideas are right, they will transform our understanding of the relationship between physics and biology" and may radically revise the notion of random evolution and the debate over consciousness and free will.

    Finding this natural basis of life has proved elusive, but in the eloquent and creative Into the Cool, Eric D. Schneider and Dorion Sagan look for answers in a surprising place: the second law of thermodynamics. This second law refers to energy's inevitable tendency to change from being concentrated in one place to becoming spread out over time. In this scientific tour de force, Schneider and Sagan show how the second law is behind evolution, ecology,economics, and even life's origin.Working from the precept that "nature abhors a gradient," Into the Cool details how complex systems emerge, enlarge, and reproduce in a world tending toward disorder. From hurricanes here to life on other worlds, from human evolution to the systems humans have created, this pervasive pull toward equilibrium governs life at its molecular base and at its peak in the elaborate structures of living complex systems. Schneider and Sagan organize their argument in a highly accessible manner, moving from descriptions of the basic physics behind energy flow to the organization of complex systems to the role of energy in life to the final section, which applies their concept of energy flow to politics, economics, and even human health.A book that needs to be grappled with by all those who wonder at the organizing principles of existence, Into the Cool will appeal to both humanists and scientists. If Charles Darwin shook the world by showing the common ancestry of all life, so Into the Cool has a similar power to disturb—and delight—by showing the common roots in energy flow of all complex, organized, and naturally functioning systems.“Whether one is considering the difference between heat and cold or between inflated prices and market values, Schneider and Sagan argue, we can apply insights from thermodynamics and entropy to understand how systems tend toward equilibrium. The result is an impressive work that ranges across disciplinary boundaries and draws from disparate literatures without blinking.”—Publishers Weekly

    We do not know much about the scientific achievements of our ancestors. Is it possible that there were highly advanced civilizations in past, whose technological achievements have been completely forgotten? Now there can be an objective verification, because Rigveda has been remarkably well preserved. Ancient Indians went to extreme lengths to preserve the Vedas. They are in the same form today, that they have been several thousand years earlier. The question is why? Why did generations of Indians go through so much trouble to preserve the Vedas, while the apparent meaning seems to be so mundane. The reason is that Vedas are coded, and once you understand that code, it has such a powerful message that is going to transform your perception of humanity. This book describes the scientific meaning of Vedas and other Hindu scriptures and compares them with currently accepted scientific wisdom.

    Aravamudan narrates the gripping story of the people who built India s space research programme and how they did it from the rocket engineers who laid the foundation to the savvy young engineers who keep Indian spaceships flying today. It is the tale of an Indian organisation that defied international bans and embargos, worked with laughably meagre resources, evolved its own technology and grew into a major space power. Today, ISRO creates, builds and launches gigantic rockets which carry the complex spacecraft that form the neural network not just of our own country but those of other countries too.This is a made-in-India story like no other.

    This ninth edition covers both analytical and empirical approaches to the subject. The examples and templates provide students with resources for computer-numerical solutions.

    The book is intended to be used in a one-semester course covering modern physics for students who have already had basic physics and calculus courses. The balance of the book leans more toward ideas than toward experimental methods and practical applications because the beginning student is better served by a conceptual framework than by a mass of details. The sequence of topics follows a logical, rather than strictly historical, order. Relativity and quantum ideas are considered first to provide a framework for understanding the physics of atoms and nuclei. The theory of the atom is then developed, and followed by a discussion of the properties of aggregates of atoms, which includes a look at statistical mechanics. Finally atomic nuclei and elementary particles are examined.

    The army blamed “human error†and a sordid love triangle. Though overshadowed by Three Mile Island, SL-1 remains the only fatal nuclear reactor incident in American history. Todd Tucker, who first heard the rumors about the Idaho Falls explosion as a trainee in the navy’s nuclear program, suspected there was more to the accident than rumors suggested. Poring over hundreds of pages of primary sources and interviewing survivors revealed that the army and its contractors had deliberately obscured the true cause of the accident, which resulted from poor engineering as much as uncontrolled passions. The National Reactor Testing Station, where the meltdown occurred, had been a proving ground where engineers, generals, and admirals attempted to realize the Atomic Age dream of unlimited power—amid the frantic race for nuclear power between the army, the navy, and the air force. The fruit of those ambitious plans included that of the nation’s unofficial nuclear patriarch, Admiral Rickover, whose “true submarine,†the USS Nautilus, would forever change naval warfare. But with the meltdown in Idaho came the end of the army’s program and the beginning of the navy’s long-standing monopoly on military nuclear power. Atomic America provides a fast-paced narrative history, advocating caution and accountability in harnessing nuclear energy.
