Roger Penrose Knihy

Presents a series of lectures delivered in 1994 by Hawking and Penrose, renowned professors at Cambridge and Oxford, respectively, on the general topic of how mathematical physics might best represent the realities of the universe.

From the best-selling author of The Emperor’s New Mind and The Road to Reality, a groundbreaking book that provides new views on three of cosmology’s most profound questions: What, if anything, came before the Big Bang? What is the source of order in our universe? What is its ultimate future?Current understanding of our universe dictates that all matter will eventually thin out to zero density, with huge black holes finally evaporating away into massless energy. Roger Penrose—one of the most innovative mathematicians of our time—turns around this predominant picture of the universe’s “heat death,” arguing how the expected ultimate fate of our accelerating, expanding universe can actually be reinterpreted as the “Big Bang” of a new one.Along the way to this remarkable cosmological picture, Penrose sheds new light on basic principles that underlie the behavior of our universe, describing various standard and nonstandard cosmological models, the fundamental role of the cosmic microwave background, and the key status of black holes. Ideal for both the amateur astronomer and the advanced physicist—with plenty of exciting insights for each—Cycles of Time is certain to provoke and challenge.Intellectually thrilling and accessible, this is another essential guide to the universe from one of our preeminent thinkers.

In this book, Roger Penrose presents a masterly summary of those areas of physics in which he feels there are major unsolved problems. These ideas are then challenged by three distinguished experts from different backgrounds - Abner Shimony and Nancy Cartwright as Philosophers of science and Stephen Hawking as a theoretical physicist and cosmologist. Finally, Roger Penrose responds to their thought-provoking criticisms. This paperback edition has been updated to include a striking and easily accessible example of Gödel's theorem, and a ground-breaking proposal for a physical experiment designed to test some of Penrose's most novel ideas about quantum mechanics. Penrose's enthusiasm, insight and good humour shine through this accessible, illuminating, and brilliant account of 21st-century theoretical physics.

Ve chvíli, kdy krach nadnárodní společnosti Eupacus rozpoutá totální kolaps pozemské ekonomiky, zůstane na Marsu pět tisíc vědců, techniků i obyčejných turistů, odříznutých od zbytku lidstva. Žádné vesmírné lodě s turisty a materiálem již nepřiletí, televize přestala vysílat, pozemské komunikační stanice jsou mimo provoz. Osazenstvo několika kopulí je na nehostinné planetě odkázáno jen samo na sebe a rozhodne se nejen bojovat o přežití, ale také se pokusit vybudovat lepší, spravedlivější společnost, v níž by katastrofy, jaká právě postihla Zemi, neměly místo. Vyprávění několika hlavních protagonistů nám přiblíží první hektické období utváření nové společnosti a seznámí nás s těžko pochopitelnými výzkumy skupiny vědců, pátrajících po prchavé skvrně Omega, základní stavebnice hmoty. A kromě toho všeho je tu Mars. Nehybná, mlčící planeta, která však promlouvá k těm, kdo jsou schopni ji uslyšet.

Focusing on the theory of twistors and 2-spinors, this book explores their application to space-time geometry, highlighting their growing significance in understanding physical laws. It offers an in-depth examination of the conformal approach to space-time infinity, discussing general-relativistic mass and angular momentum. Additionally, the text provides a thorough spinorial classification of the full space-time curvature tensor and delves into the geometry of null geodesics, making it a valuable resource for those studying advanced concepts in physics and mathematics.
