Book excerpt: Stephen Hawking avrebbe dovuto passare più tempo ad aiutare la scienza medica a risolvere i problemi, compreso il suo, anziché cercare buchi neri nelle profondità della sua "mente brillante", criticando aspramente quella che lo ha creato. Il dramma che lo ha reso disabile avrebbe potuto spingerlo a usare la sua "mente brillante" per aiutare gli altri sulla terra, invece di cercare buchi neri e inseguire l'infinitesimo, lasciando che se ne occupino quelli che non sono in condizioni fisiche come la sua. Avrebbe potuto divertirsi con un telescopio a casa sua, come facevo io quando abitavo a Miami, North Miami Beach, e poi a Oakland Park, mentre lo scorrere del tempo scandiva la mia vita. A quanto ne so, l'orgoglio di essere l'uomo dei buchi neri non lo sta aiutando, perché avrebbe dovuto spiegarci come difenderci da questi mostri anti Dio. Se uno di loro va fuori orbita e ci viene addosso, lui e la sua famiglia diventano cibo per buchi neri, poiché non hanno un Dio che li difende.

Download or read book Hawking on the Big Bang and Black Holes written by Stephen W. Hawking and published by World Scientific. This book was released on 1993 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stephen Hawking, the Lucasian Professor of Mathematics at Cambridge University, has made important theoretical contributions to gravitational theory and has played a major role in the development of cosmology and black hole physics. Hawking's early work, partly in collaboration with Roger Penrose, showed the significance of spacetime singularities for the big bang and black holes. His later work has been concerned with a deeper understanding of these two issues. The work required extensive use of the two great intellectual achievements of the first half of the Twentieth Century: general relativity and quantum mechanics; and these are reflected in the reprinted articles. Hawking's key contributions on black hole radiation and the no-boundary condition on the origin of the universe are included. The present compilation of Stephen Hawking's most important work also includes an introduction by him, which guides the reader though the major highlights of the volume. This volume is thus an essentialitem in any library and will be an important reference source for those interested in theoretical physics and applied mathematics. It is an excellent thing to have so many of Professor Hawking's most important contributions to the theory of black holes and space-time singularities all collected together in one handy volume. I am very glad to have them". Roger Penrose (Oxford) "This was an excellent idea to put the best papers by Stephen Hawking together. Even his papers written many years ago remain extremely useful for those who study classical and quantum gravity. By watching the evolution of his ideas one can get a very clear picture of the development of quantum cosmology during thelast quarter of this century". Andrei Linde (Stanford) "This review could have been quite short: 'The book contains a selection of 21 of Stephen Hawking's most significant papers with an overview written by the author'. This w
Download or read book Black Holes written by Stephen Hawking and published by Bantam. This book was released on 2016-08-23 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The legendary physicist explores his favorite subject in a pair of enlightening, accessible, and cleverly illustrated essays for curious readers, originally delivered as BBC lectures. “It is said that fact is sometimes stranger than fiction, and nowhere is that more true than in the case of black holes. Black holes are stranger than anything dreamed up by science-fiction writers, but they are firmly matters of science fact.” For decades, Stephen Hawking has been fascinated by black holes. He believes that if we understood the challenges they pose to the very nature of space and time, we could unlock the secrets of the universe. In these conversational pieces, Hawking’s sense of wonder is infectious as he holds forth on what we know about black holes, what we still don’t know, and theoretical answers to more specific questions, such as: What would happen if you ever got sucked into one? Annotated and with an introduction by BBC News science editor David Shukman, featuring whimsical and illuminating illustrations, Black Holes offers a candid peek into one of the great scientific mysteries of all time. Praise for Stephen Hawking “[Hawking] can explain the complexities of cosmological physics with an engaging combination of clarity and wit. . . . His is a brain of extraordinary power.”—The New York Review of Books “Hawking clearly possesses a natural teacher’s gifts—easy, good-natured humor and an ability to illustrate highly complex propositions with analogies plucked from daily life.”—The New York Times “A high priest of physics, one of a handful of theorists who may be on the verge of reading God’s mind.”—Los Angeles Times

Book excerpt: NEW YORK TIMES BESTSELLER • Stephen Hawking’s closest collaborator offers the intellectual superstar’s final thoughts on the cosmos—a dramatic revision of the theory he put forward in A Brief History of Time. “This superbly written book offers insight into an extraordinary individual, the creative process, and the scope and limits of our current understanding of the cosmos.”—Lord Martin Rees Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. In order to solve this mystery, Hawking studied the big bang origin of the universe, but his early work ran into a crisis when the math predicted many big bangs producing a multiverse—countless different universes, most of which would be far too bizarre to harbor life. Holed up in the theoretical physics department at Cambridge, Stephen Hawking and his friend and collaborator Thomas Hertog worked on this problem for twenty years, developing a new theory of the cosmos that could account for the emergence of life. Peering into the extreme quantum physics of cosmic holograms and venturing far back in time to our deepest roots, they were startled to find a deeper level of evolution in which the physical laws themselves transform and simplify until particles, forces, and even time itself fades away. This discovery led them to a revolutionary idea: The laws of physics are not set in stone but are born and co-evolve as the universe they govern takes shape. As Hawking’s final days drew near, the two collaborators published their theory, which proposed a radical new Darwinian perspective on the origins of our universe. On the Origin of Time offers a striking new vision of the universe’s birth that will profoundly transform the way we think about our place in the order of the cosmos and may ultimately prove to be Hawking’s greatest legacy.

Available in PDF, EPUB and Kindle. Book excerpt: #1 NEW YORK TIMES BESTSELLER • The world-famous cosmologist and author of A Brief History of Time leaves us with his final thoughts on the biggest questions facing humankind. “Hawking’s parting gift to humanity . . . a book every thinking person worried about humanity’s future should read.”—NPR NAMED ONE OF THE BEST BOOKS OF THE YEAR BY Forbes • The Guardian • Wired Stephen Hawking was the most renowned scientist since Einstein, known both for his groundbreaking work in physics and cosmology and for his mischievous sense of humor. He educated millions of readers about the origins of the universe and the nature of black holes, and inspired millions more by defying a terrifying early prognosis of ALS, which originally gave him only two years to live. In later life he could communicate only by using a few facial muscles, but he continued to advance his field and serve as a revered voice on social and humanitarian issues. Hawking not only unraveled some of the universe’s greatest mysteries but also believed science plays a critical role in fixing problems here on Earth. Now, as we face immense challenges on our planet—including climate change, the threat of nuclear war, and the development of artificial intelligence—he turns his attention to the most urgent issues facing us. Will humanity survive? Should we colonize space? Does God exist? These are just a few of the questions Hawking addresses in this wide-ranging, passionately argued final book from one of the greatest minds in history. Featuring a foreword by Eddie Redmayne, who won an Oscar playing Stephen Hawking, an introduction by Nobel Laureate Kip Thorne, and an afterword from Hawking’s daughter, Lucy, Brief Answers to the Big Questions is a brilliant last message to the world. Praise for Brief Answers to the Big Questions “[Hawking is] a symbol of the soaring power of the human mind.”—The Washington Post “Hawking’s final message to readers . . . is a hopeful one.”—CNN “Brisk, lucid peeks into the future of science and of humanity.”—The Wall Street Journal “Hawking pulls no punches on subjects like machines taking over, the biggest threat to Earth, and the possibilities of intelligent life in space.”—Quartz “Effortlessly instructive, absorbing, up to the minute and—where it matters—witty.”—The Guardian “This beautiful little book is a fitting last twinkle from a new star in the firmament above.”—The Telegraph

Book excerpt: Author William Moreira has spent decades studying and seeking Godsometimes while flying high above the clouds in his Cessna. In that time, he has discovered that God is everywhere. Now, in this new study, he takes issue with Stephen Hawking and other scientists and individuals who argue against Gods existence. He seeks to disprove their theories and contemplates ways you can use your brain to discover the true nature of the universe; live in a manner that will lead to a happy place in eternity; and argue against the theories of Hawking and his constituents. While some aspects of the universe will remain a mystery, its clear that God exists. Whats more, its up to you to find the right path to moral evolution. You must look at the infinity of the illuminated dark matter encrusted within the stars and, in exaltation, accept that there is a super power and that God is everywhere. Join Moreira as he takes on various foolish views about the universe and existence.

Download or read book Stephen Hawking s Universe written by David Filkin and published by Basic Books. This book was released on 1998-10-09 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stephen Hawking's A Brief History of Time has sold over 9 million copies worldwide. Now, in everyday language, Stephen Hawking's Universe reveals step-by-step how we can all share his understanding of the cosmos, and our own place within it. Stargazing has never been the same since cosmologists discovered that galaxies are moving away from each other at an extraordinary speed. It was this understanding of the movement of galaxies that allowed scientists to develop a theory of how the universe was created—the Big Bang theory. Working with this theory, Stephen Hawking and other physicists felt challenged to come up with a scientific picture that would tackle the fundamental question: what is the nature of the universe? Stephen Hawking's Universe charts this work and provides simple explanations for phenomena that arouse our curiosity. This work is a voyage of discovery with an astonishing set of conclusions that will enable us to understand how matter can be produced from nothing at all and will provide us with an explanation for the basis of our existence and that of everything around us.
Download or read book Space Black Holes and Time written by Stephen Hawking and published by . This book was released on 2017-12-11 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: To understand how a black hole might be formed, we first need an understanding of the life cycle of a star. A star is formed when a large amount of gas (mostly hydrogen) starts to collapse in on itself due to its gravitational attraction. As it contracts, the atoms of the gas collide with each other more and more frequently and at greater and greater speeds ¿the gas heats up. Eventually, the gas will be so hot that when the hydrogen atoms collide they no longer bounce off each other, but instead coalesce to form helium. The heat released in this reaction, which is like a controlled hydrogen bomb explosion, is what makes the star shine. This additional heat also increases the pressure of the gas until it is sufficient to balance the gravitational attraction, and the gas stops contracting. It is a bit like a balloon ¿ there is a balance between the pressure of the air inside, which is trying to make the balloon expand, and the tension in the rubber, which is trying to make the balloon smaller. Stars will remain stable like this for a long time, with heat from the nuclear reactions balancing the gravitational attraction. Eventually, however, the star will run out of its hydrogen and other nuclear fuels. Paradoxically, the more fuel a star starts off with, the sooner it runs out. This is because the more massive the star is, the hotter it needs to be to balance its gravitational attraction. And the hotter it is, the faster it will use up its fuel. Our sun has probably got enough fuel for another five thousand million years or so, but more massive stars can use up their fuel in as little as one hundred million years, much less than the age of the universe. When a star runs out of fuel, it starts to cool off and so to contract.

Book excerpt: Collector s Edition with Audiobook read by the AuthorStephen Hawking is widely believed to be one of the world s greatest minds: a brilliant theoretical physicist whose work helped to reconfigure models of the universe and to redefine what s in it. Imagine sitting in a room listening to Hawking discuss these achievements and place them in historical context. It would be like hearing Christopher Columbus on the New World.Hawking presents a series of seven lec-tures covering everything from big bang to black holes to string theory that capture not only the brilliance of Hawking s mind but his characteristic wit as well. Of his research on black holes, which absorbed him for more than a decade, he says, It might seem a bit like looking for a black cat in a coal cellar. Hawking begins with a history of ideas about the universe, from Aristotle s determination that the Earth is round to Hubble s discovery, over 2000 years later, that the universe is expanding. Using that as a launching pad, he explores the reaches of modern physics, including theories on the origin of the universe (e.g., the big bang), the nature of black holes, and space-time.
