Roger Penrose Ordine dei libri (cronologico)

Komputery grają już w szachy na poziomie arcymistrzowskim, ale czy rozumieją tę grę tak samo jak my? Czy komputer może kiedykolwiek działać identycznie jak ludzki umysł? W tej pasjonującej i w wielu miejscach kontrowersyjnej książce Roger Penrose – wybitny fizyk i zdobywca Nagrody Nobla w 2020 roku - przedstawia pogląd, że istnieją pewne aspekty ludzkiego myślenia, których maszyna nigdy nie będzie mogła naśladować. Penrose bada, co fizyka i matematyka mogą, a czego nie mogą nam powiedzieć o sposobie funkcjonowania umysłu, i co musimy wiedzieć, aby zrozumieć fizyczne procesy leżące u podstaw świadomości. Autor dochodzi do wniosku, że do wyjaśnienia działania umysłu konieczne są jeszcze głębsze prawa niż mechanika kwantowa. Aby wesprzeć tę tezę, Penrose zabiera czytelnika w cudowną podróż, która obejmuje takie tematy jak liczby zespolone, maszyny Turinga, teoria złożoności, mechanika kwantowa, przestrzenie fazowe, czarne dziury, białe dziury, promieniowanie Hawkinga, entropia, quasi-kryształy, struktura mózgu i dziesiątki innych pasjonujących zagadnień. Nowy umysł cesarza to książka dla wszystkich, którzy poważnie interesują się współczesną fizyką i jej związkiem z kwestiami filozoficznymi, jak również ważny głos w debacie nad przyszłością sztucznej inteligencji.

Da oltre un secolo, la fisica teorica ha registrato trionfi, dalle rivoluzioni della relatività einsteiniana alla meccanica quantistica. La ricerca di una Teoria del Tutto ha portato a risultati significativi, come il modello cosmologico standard, che descrive l'evoluzione dell'universo dal Big Bang e le sue possibili destinazioni, e la teoria delle stringhe, che propone una visione elegante della materia e dello spaziotempo. Tuttavia, Roger Penrose, con la sua consueta incisività, mette in discussione questa narrativa. Si chiede se l'eleganza della teoria delle stringhe e la sua popolarità stiano distogliendo l'attenzione da ipotesi meno spettacolari ma più solide. Inoltre, solleva interrogativi sulla validità delle attuali teorie cosmologiche, basate sul dogma del modello inflazionario, e sulla fiducia riposta nei fondamenti concettuali della meccanica quantistica, nonostante la loro fragilità. Con il suo sguardo critico e la sua originalità, Penrose offre un'analisi profonda e sorprendente delle forze e delle debolezze della scienza fondamentale contemporanea, invitando a riflettere sulla direzione della ricerca scientifica.

This book offers a radical new theory of the origin, and ultimate end, of the Universe.

Fearful Symmetry brings the incredible discoveries of contemporary physics within everyone's grasp. A. Zee, a distinguished physicist and skillful expositor, tells the exciting story of how today's theoretical physicists are following Einstein in their search for the beauty and simplicity of Nature. Animated by a sense of reverence and whimsy, the book describes the majestic sweep and accomplishments of twentieth-century physics. In the end, we stand in awe before the grand vision of modern physics--one of the greatest chapters in the intellectual history of humankind.

Roger Penrose, one of the most accomplished scientists of our time, presents the only comprehensive and comprehensible account of the physics of the universe. From the very first attempts by the Greeks to grapple with the complexities of our known world to the latest application of infinity in physics, The Road to Reality carefully explores the movement of the smallest atomic particles and reaches into the vastness of intergalactic space. Here, Penrose examines the mathematical foundations of the physical universe, exposing the underlying beauty of physics and giving us one the most important works in modern science writing.

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.

WHITE MARS is Brian Aldiss' Utopian vision of mankind's future in space, written in collaboration with distinguished physicist Roger Penrose. Halfway through the next century, an organisation called EUPACUS, consisting of all the leading industrialised nations, has found a way to colonise Mars. They have, however, decided to protect the planet for scientific research. Human beings will live in great, self- perpetuating domes, producing their own food and oxygen, while drawing water from the planet's core. The option of terraforming the planet, bombarding it with CFCs in order to give it an atmosphere, has been discontinued. Owing to economic collapse on earth the martian colony is cut off from the mother planet ('Downstairs' as they call it). The head of the colony, Tim Jefferies, sets out to create a perfect society. Some, however, only want to get home, and think that the Utopian ideals (which are all broadcast back to Earth) will only hamper their rescue. An arresting novel of ideals and conflicts WHITE MARS contrasts the warmth of community in the domes with the icy wastes of Mars.

An accessible, illuminating and stimulating introduction to Roger Penrose's vision of theoretical physics for the twenty-first century. Includes incisive contributions from Abner Shimony, Nancy Cartwright and Stephen Hawking. This is a fascinating account of the problems of modern physics, ranging from small-scale quantum physics to the physics of the Universe. schovat popis

Einstein noted the paradox of the universe's comprehensibility, prompting the question of whether quantum theory and general relativity can be unified in a single quantum theory of gravity. This work features two renowned physicists, Stephen Hawking and Roger Penrose, who present their contrasting views based on six lectures followed by a debate, originally held at the Isaac Newton Institute for Mathematical Sciences, Cambridge. They explore the construction of a quantum gravity theory that could elucidate the early moments of the big bang and the nature of black holes. Key questions arise: Why does the universe conform to Einstein's predictions without visible quantum effects? What quantum processes lead to black hole evaporation, and where does the swallowed information go? Why does time move forward? Penrose, echoing Einstein, doubts that quantum mechanics is a final theory, while Hawking argues that general relativity fails to explain the universe's origin. He advocates for a quantum theory of gravity and the no-boundary hypothesis. Penrose, the realist, believes in an eternally expanding universe, using geometry and twistor theory to explain it. Their final debate reveals the profound differences in their approaches to merging quantum mechanics and relativity, highlighting their distinct perspectives on understanding the universe's complexities.

Nel cervello succedono cose che un computer non può fare. Da questa semplice constatazione Roger Penrose prende le mosse per comporre il mosaico di un'indagine a cavallo tra scienza e filosofia, il cui oggetto è: esiste la coscienza? Cosa significa pensare? La fisica che conosciamo basta a spiegare il funzionamento della nostra mente? E se è vero che pensare significa essere, cosa ci rende umani?

The proponents of artificial intelligence want to prove that it is only a matter of time before computers will be doing everything that a human mind can do. The author reacts against this view, by saying there is some facet of human thinking that can never be emulated by a machine.
