Scharf Caleb Bücher

A New Scientist Top Ten Books of 2012. We have long understood black holes to be where the universe as we know it comes to an end - huge bodies so destructive that not even light can escape their deadly power. In Gravity's Engines, however, renowned astrophysicist Caleb Scharf reveals an entirely new, and crucially important, side to these mysterious chasms. The latest research has located super-sized black holes, often billions of times more massive than the Sun, which have the power to rearrange the cosmos and control entire galaxies of stars. Engaging with our deepest questions about our origins, Scharf shows how, without these black holes, life in the universe could not exist. 'This book should be on your shelf if you want to know why our Universe is the way it is.' Focus 'Caleb Scharf is a lively and eloquent writer as well as a fine scientist. Gravity's Engines presents topics at the frontiers of our understanding which have not hitherto been presented so clearly to a general readership.' Sir Martin Rees 'Using rich language and a brilliant command of metaphor, Scharf weaves a wonderfully detailed tapestry of what modern astronomy is all about.' Nature 'Scharf serves as an appealing tour guide to the eerie, infinite corridors of the cosmos in which we reside.' Prospect

In The Zoomable Universe, the award-winning astrobiologist Caleb Scharf and the acclaimed artist Ron Miller take us on an epic tour through all known scales of reality, from the largest possible magnitude to the smallest. Drawing on cutting-edge science, they begin at the limits of the observable universe, a scale spanning 10 27 metersabout 93 billion light-years. And they end in the subatomic realm, at 10 -35 meters, where the fabric of space-time itself confounds all known rules of physics. In between are galaxies, stars and planets, oceans and continents, plants and animals, microorganisms, atoms, and much, much more.

When Copernicus proposed that the Earth was not the fixed point at the center of the known universe (and therefore we are not unique), he set in motion a colossal scientific juggernaut, forever changing our vision of nature.

A groundbreaking revision of the Copernican Principle which is that the Earth was not the fixed point at the center of the known universe (and therefore we are not unique). Renowned astrophysicist and author Caleb Scharf argues that the principle has never been entirely true and therefore requires that we put aside our Copernican worldview and embrace the possibility that we are in a delicate balance between mediocrity and significance, order and chaos

"Your information has a life of its own, and it's using you to get what it wants. One of the most peculiar and possibly unique features of humans is the vast amount of information we carry outside our biological selves. But in our rush to build the infrastructure for the 20 quintillion bits we create every day, we've failed to ask exactly why we're expending ever-increasing amounts of energy, resources, and human effort to maintain all this data. Drawing on deep ideas and frontier thinking in evolutionary biology, computer science, information theory, and astrobiology, Caleb Scharf argues that information is, in a very real sense, alive. All the data we create-all of our emails, tweets, selfies, A.I.-generated text and funny cat videos-amounts to an aggregate lifeform. It has goals and needs. It can control our behavior and influence our well-being. And it's an organism that has evolved right alongside us. This symbiotic relationship with information offers a startling new lens for looking at the world. Data isn't just something we produce; it's the reason we exist. This powerful idea has the potential to upend the way we think about our technology, our role as humans, and the fundamental nature of life. The Ascent of Information offers a humbling vision of a universe built of and for information. Scharf explores how our relationship with data will affect our ongoing evolution as a species. Understanding this relationship will be crucial to preventing our data from becoming more of a burden than an asset, and to preserving the possibility of a human future"-- Provided by publisher

Kompleks Kopernika Caleba Scharfa to książka o poszukiwaniu odpowiedzi na pytania, kt�re ludzkość zadaje sobie niemal od zarania dziej�w. Jakie jest miejsce Ziemi we Wszechświecie? Czy jesteśmy w kosmosie sami? Czy jesteśmy ważni i wyjątkowi, czy całkiem nieistotni? Rozpoczynając od kopernikańskiej wizji Wszechświata, zgodnie z kt�rą Ziemia i zamieszkujący ją ludzie nie zajmują uprzywilejowanej pozycji w przestrzeni kosmicznej, autor konsekwentnie kreśli obraz przemian, jakim podlegały poglądy na budowę Wszechświata. W błyskotliwy i przekonujący spos�b opisuje ewolucję świadomości człowieka na temat jego miejsca w kosmosie
