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.

    An airliner capable of flying at more than twice the speed of sound, the Concorde had completed 25 years of successful flights, whisking wealthy passengers--from diplomats to rock stars to corporate titans--between continents on brief and glamorous flights. Yet on this fateful day, the chartered Concorde jet, en route to America, crashed and killed all 109 passengers and crew onboard and four people on the ground. Urgent questions immediately arose as investigators scrambled to discover what had gone wrong. What caused the fire? Could it have been prevented? And, most urgently, was the Concorde safe to fly? Last Days of the Concorde addresses these issues and many more, offering a fascinating insider's look at the dramatic disaster, the hunt for clues, and the systemic overhauls that followed the crash.

    Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium, and Mare Sirenum—on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science.In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.Johnson’s fascination with Mars began as a child in Kentucky, turning over rocks with her father and looking at planets in the night sky. She now conducts fieldwork in some of Earth’s most hostile environments, such as the Dry Valleys of Antarctica and the salt flats of Western Australia, developing methods for detecting life on other worlds. Here, with poetic precision, she interlaces her own personal journey—as a female scientist and a mother—with tales of other seekers, from Percival Lowell, who was convinced that a utopian society existed on Mars, to Audouin Dollfus, who tried to carry out astronomical observations from a stratospheric balloon. In the process, she shows how the story of Mars is also a story about Earth: This other world has been our mirror, our foil, a telltale reflection of our own anxieties and yearnings.Empathetic and evocative, The Sirens of Mars offers an unlikely natural history of a place where no human has ever set foot, while providing a vivid portrait of our quest to defy our isolation in the cosmos.

    What really happens at the most fundamental levels of nature?Introducing Particle Physics explores the very frontiers of our knowledge, even showing how particle physicists are now using theory and experiment to probe our very concept of what is real.From the earliest history of the atomic theory through to supersymmetry, micro-black holes, dark matter, the Higgs boson, and the possibly mythical graviton, practising physicist and CERN contributor Tom Whyntie gives us a mind-expanding tour of cutting-edge science.Featuring brilliant illustrations from Oliver Pugh, Introducing Particle Physics is a unique tour through the most astonishing and challenging science being undertaken today.

    But what will this future look like? In 2062, world-leading researcher Toby Walsh considers the impact AI will have on work, war, economics, politics, everyday life and even death. Will automation take away most jobs? Will robots become conscious and take over? Will we become immortal machines ourselves, uploading our brains to the cloud? How will politics adjust to the post-truth, post-privacy digitised world? When we have succeeded in building intelligent machines, how will life on this planet unfold?Based on a deep understanding of technology, 2062 describes the choices we need to make today to ensure that the future remains bright.‘Clarity and sanity in a world full of fog and uncertainty – a timely book about the race to remain human.’—RICHARD WATSON, author of Digital Vs. Human and futurist-in-residence at Imperial College, London‘One of the deepest questions facing humanity, pondered by a mind well and truly up to the task.’—ADAM SPENCER, broadcaster

    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.

    Now, at a moment when mathematicians are finally moving in on a proof, Dartmouth professor Dan Rockmore tells the riveting history of the hunt for a solution.In 1859 German professor Bernhard Riemann postulated a law capable of describing with an amazing degree of accuracy the occurrence of the prime numbers. Rockmore takes us all the way from Euclid to the mysteries of quantum chaos to show how the Riemann hypothesis lies at the very heart of some of the most cutting-edge research going on today in physics and mathematics.

    Birth of a Theorem is Villani’s own account of the years leading up to the award. It invites readers inside the mind of a great mathematician as he wrestles with the most important work of his career.But you don’t have to understand nonlinear Landau damping to love Birth of a Theorem. It doesn’t simplify or overexplain; rather, it invites readers into collaboration. Villani’s diaries, emails, and musings enmesh you in the process of discovery. You join him in unproductive lulls and late-night breakthroughs. You’re privy to the dining-hall conversations at the world’s greatest research institutions. Villani shares his favorite songs, his love of manga, and the imaginative stories he tells his children. In mathematics, as in any creative work, it is the thinker’s whole life that propels discovery—and with Birth of a Theorem, Cédric Villani welcomes you into his.

    Traces the history of time from Augustine's suggestion that there is no time, to the flowing time of Newton, the static time of Einstein, and then back, to the idea that there is no time in quantum gravity.

    Though he is still best known for this finding, his partnership with his sister Caroline yielded groundbreaking work, including techniques that remain in use today. The duo pioneered comprehensive surveys of the night sky, carefully categorizing every visible object in the void. Caroline wrote an influential catalogue of nebulae, and William discovered infrared radiation. Celebrated science writer Michael Lemonick guides readers through the depths of the solar system and into his protagonists' private lives: William developed bizarre theories about inhabitants of the sun; he procured an unheard-of salary for Caroline even while haggling with King George III over the funding for an enormous, forty-foot telescope; the siblings feuded over William's marriage and eventually reconciled. Erudite and accessible, The Georgian Star is a lively portrait of the pair who invented modern astronomy.
