Lawrence M. Krauss

Our understanding of ourselves and the cosmos has advanced immeasurably over the last five hundred years of modern science, yet many fundamental mysteries of existence persist. How did our Universe begin, if it even had a beginning? How big is it? What's at the bottom of a black hole? How did life on Earth arise? Are we alone? Is time travel possible?These mysteries define the threshold of the unknown. To explore that threshold is to gain a deeper understanding of just how far science has progressed. In The Known Unknowns, bestselling popular science writer Lawrence Krauss explores science's greatest known unknowns. Covering time, space, physical law, life and consciousness, Krauss introduces readers to the topics that will shape the state of science of the next few decades, and invites us to ponder and appreciate the universe in which we live.

Hur uppkom livet på jorden? Är vi ensamma i universum? Är tidsresor möjliga? Och vad döljer sig bortom det vi kan se?I den här boken ger den bästsäljande författaren och fysikern Lawrence Krauss inblick i de kvarstående mysterier som femhundra år av modern vetenskap ännu inte lyckats lösa. Med lätt hand låter han läsaren bekanta sig med kunskapens nuvarande gränstrakter. Och via de frågor om tid och materia, liv och medvetande som stakar ut forskningens riktning för överskådlig framtid öppnar sig en glipa i dörren mot det okända.

'Brilliant and fundamental, this is the necessary book about our prime global emergency' Ian McEwanThe news is full of hotly debated and divergent claims about the impacts and risks of climate change. Lawrence Krauss, one of the world’s most respected physicists and science popularizers, cuts through the confusion by succinctly presenting the underlying science of climate change.The Physics of Climate Change provides a clear, accurate and accessible perspective on climate science and the risks of global inaction. Krauss’s narrative explores the history of how scientists progressed to our current understanding of the Earth’s climate and its future. Its generous complement of informative diagrams and illustrations allows readers to assess which climate predictions are securely based on analysis of empirical data, and which are more speculative.The Physics of Climate Change is required reading for anyone interested in understanding humanity’s role in the future of our planet.

Suurin osa ilmakehänlämmittävästä vaikutuksesta perustuu infrapunasäteilynabsorboitumiseen hiilidioksidiin. Tämän perysfysiikka onmelko yksinkertaista ja se ymmärretään erittäin hyvin. Myös mittaustulokset ovat hyvin linjassa sen kanssa.Tässä kirjassa maineikas fyysikko ja tieteen kansantajuistaja Lawrence M. Krauss esittelee kasvihuoneilmiön ja ilmastonmuutoksen fysiikan ensimmäisistä periaatteista alkaen. Lopputuloksena on yleistajuinen ja johdonmukainen esitys ilmastonmuutoksen kiistattomista perusteista, jotka jokaisen pitäisi tuntea.

Lawrence Krauss explores the greatest unanswered questions at the forefront of science today, and likely for the coming century and beyond. Internationally known theoretical physicist and bestselling author Lawrence Krauss explores science's greatest unanswered questions. Three of the most important words in science are "I don't know." Not knowing implies a Universe of opportunities--the possibility of discovery and surprise. Our understanding of science has advanced immeasurably over the last five hundred years, yet many fundamental mysteries of existence persist: How did our Universe begin? How big is the Universe? Is time travel possible? What's at the center of a black hole? How did life on Earth arise? Are we alone? What is consciousness, and can we create it? These mysteries define the scientific forefront--the threshold of the unknown. To explore that threshold is to gain a deeper understanding of just how far science has progressed. Covering time, space, matter, life, and consciousness, Krauss introduces readers to topics that will shape the state of science for the next century, providing us all passport to our own journeys of exploration and discovery.

From award-winning physicist, public intellectual, and the bestselling author of A Universe from Nothing Lawrence Krauss, comes "a masterful blend of history, modern physics, and cosmic perspective that empowers the reader to not only embrace our understanding of the universe, but also revel in what remains to be discovered" (Neil deGrasse Tyson, American Museum of Natural History). In this grand poetic vision of the universe, Lawrence Krauss tells the dramatic story of the discovery of the hidden world that underlies reality--and our place within it. Reality is not what you think or sense--it's weird, wild, and counterintuitive, and its inner workings seem at least as implausible as the idea that something can come from nothing. With his trademark wit and accessible style, Krauss leads us to realms so small that they are invisible to microscopes, to the birth and rebirth of light, and into the natural forces that govern our existence. His unique blend of rigorous research and engaging storytelling invites us into the lives and minds of remarkable scientists who have helped unravel the unexpected fabric of reality with reasoning rather than superstition and dogma, and to explain how everything we see--and can't see--came about. A passionate advocate for reason, Krauss gives the rationale for the seemingly irrational--and the mysteries and apparent contradictions of quantum physics, and explores what that means for our lives here on Earth--and beyond. At its core, The Greatest Story Ever Told--So Far is about the best of what it means to be human--an epic history of our ultimately purposeless universe that addresses the question, "Why are we here?"

The first book to briefly and clearly present the science of climate change in a way that is accessible to laypeople, providing the perspective needed to understand and assess the foundations and predictions of climate change. "Brilliant and fundamental, this is the necessary book about our prime global emergency. Here you'll find the facts, the processes, the physics of our complex and changing climate, but delivered with eloquence and urgency. Lawrence Krauss writes with a clarity that transcends mere politics. Prose and poetry were never better bedfellows." --Ian McEwan, Booker Prize-winning author of Solar and Machines Like Me "Lawrence Krauss has written the ideal book for anyone interested in understanding the science of global warming. It is at once elegant, rigorous, and timely."--Elizabeth Kolbert, staff writer, The New Yorker, and Pulitzer prize-winning author of The Sixth Extinction "A brief, brilliant, and charming summary of what physicists know about climate change and how they learned it." --Sheldon Glashow, Nobel Laureate in Physics, Metcalf Distinguished Professor Emeritus, Boston University "The distinguished scientist Lawrence Krauss turns his penetrating gaze on the most pressing existential threat facing our world: climate change. It is brimming with information lucidly analysed. Such hope as there is lies in science, and a physicist of Dr. Krauss's imaginative versatility is unusually qualified to offer it." --Richard Dawkins, author of The Blind Watchmaker and Science in the Soul "Lucid and gripping, this study of the most severe challenge humans have ever faced leads the reader from the basic physics of climate change to recognition of the damage that humans have already caused and on to the prospects that lie ahead if we do not change course soon." --Noam Chomsky, Laureate Professor, University of Arizona, author of Internationalism or Extinction? "Lawrence Krauss tells the story of climate change with erudition, urgency, and passion. It is our great good luck that one of our most brilliant scientists is also such a gifted writer. This book will change the way we think about the future." --Jennifer Finney Boylan, author of Good Boy and She's Not There "Everything on climate change that I've seen is either dumbed down and bossy or written for other climate scientists. I've been looking for a book that can let me, a layperson, understand the science. This book does just what I was looking for. It is important." --Penn Jillette, Magician, author of Presto and God, No "The renowned physicist Lawrence Krauss makes the science behind one of the most important issues of our time accessible to all." --Richard C. J. Somerville, Distinguished Professor Emeritus, Scripps Institution of Oceanography, University of California, San Diego "Lawrence Krauss is a fine physicist, a talented writer, and a scientist deeply engaged with public affairs. His book deserves wide readership. The book's eloquent exposition of the science and the threats should enlighten all readers and motivate them to an urgent concern about our planet's future." --Lord Martin Rees, Astronomer Royal, former president of the Royal Society, author of On the Future: Prospects for Humanity

In this classic treatise on atheism,George H. Smith sets out to demolish what he considers the most widespread and destructive of all the myths devised by human beings - the concept of a supreme being. With painstaking scholarship and rigorous arguments, Mr. Smith examines, dissects, and refutes the myriad "proofs" offered by theists - sophisticated, professional theologians - as well as the average religious layperson. He explores the historical and psychological havoc wrought by religion in general and concludes that religious belief cannot have any place in the life of modern, rational man. "It is not my purpose to convert people to atheism . . . (but to) demonstrate that the belief in God is irrational to the point of absurdity. If a person wishes to continue believing in a god, that is his prerogative, but he can no longer excuse his belief in the name of reason and moral necessity."

"Raif Badawi's is an important voice for all of us to hear"-- Salman Rushdie Raif Badawi, a Saudi Arabian blogger, shared his thoughts on politics, religion, and liberalism online. He was sentenced to 1,000 lashes, ten years in prison, and a fine of 1 million Saudi Riyal, over a quarter of a million U.S. dollars. This politically topical polemic gathers together Badawi's pivotal texts. He expresses his opinions on life in an autocratic-Islamic state under the Sharia and his perception of freedom of expression, human and civil rights, tolerance and the necessary separation of state and religion.

Bestselling author and acclaimed physicist Lawrence Krauss offers a paradigm-shifting view of how everything that exists came to be in the first place. "Where did the universe come from? What was there before it? What will the future bring? And finally, why is there something rather than nothing?" One of the few prominent scientists today to have crossed the chasm between science and popular culture, Krauss describes the staggeringly beautiful experimental observations and mind-bending new theories that demonstrate not only can something arise from nothing, something will always arise from nothing. With a new preface about the significance of the discovery of the Higgs particle, A Universe from Nothing uses Krauss's characteristic wry humor and wonderfully clear explanations to take us back to the beginning of the beginning, presenting the most recent evidence for how our universe evolved--and the implications for how it's going to end. Provocative, challenging, and delightfully readable, this is a game-changing look at the most basic underpinning of existence and a powerful antidote to outmoded philosophical, religious, and scientific thinking.

Richard Feynmania pidetään 1900-luvun jälkipuolen tärkeimpänä fyysikkona. Feynman sai Nobelin palkinnon kvanttisähködynamiikan (QED) teorian kehittämisestä. QED selittää yhden miljardisosan tarkkuudella, miten valo ja aine vuorovaikuttavat kvanttitasolla. Feynman on tullut tunnetuksi myös kirjoina julkaistuista legendaarisista fyysikkotarinoistaan, kuten "Laskette varmaankin leikkiä, Mr. Feynman!". Kvanttimiehessä Lawrence Krauss keskittyy Richard Feynmanin tieteelliseen perintöön. Hän haluaa paljastaa ei-fyysikoille, miksi Feynman on useimpien fyysikoiden mielestä lähes myyttinen sankari ja samalla auttaa lukijoita ymmärtämään jotain keskeistä nykyfysiikasta ja Feynmanin roolista maailmankuvamme muutoksessa.

A provocative account of the astounding new answers to the most basic philosophical questions: where did the universe come from and how will it end?

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 Lawrence M. Krauss, himself a theoretical physicist and a best-selling author, offers a unique scientific biography: a rollicking narrative coupled with clear and novel expositions of science at the limits. From the death of Feynman’s childhood sweetheart during the Manhattan Project to his reluctant rise as a scientific icon, we see Feynman’s life through his science, providing a new understanding of the legacy of a man who has fascinated millions.
