Descrição da editora
From two of the world's great physicists—Stephen Hawking and Nobel laureate Roger Penrose—a lively debate about the nature of space and time
Einstein said that the most incomprehensible thing about the universe is that it is comprehensible. But was he right? Can the quantum theory of fields and Einstein's general theory of relativity, the two most accurate and successful theories in all of physics, be united into a single quantum theory of gravity? Can quantum and cosmos ever be combined? In The Nature of Space and Time, two of the world’s most famous physicists—Stephen Hawking (A Brief History of Time) and Roger Penrose (The Road to Reality)—debate these questions.
The authors outline how their positions have further diverged on a number of key issues, including the spatial geometry of the universe, inflationary versus cyclic theories of the cosmos, and the black-hole information-loss paradox. Though much progress has been made, Hawking and Penrose stress that physicists still have further to go in their quest for a quantum theory of gravity.
PUBLISHERS WEEKLY
This volume contains a series of lectures delivered in 1994 by Hawking (A Brief History of Time) and Penrose (The Emperor's New Mind), renowned professors at Cambridge and Oxford, respectively. The overall topic is how mathematical physics might best represent the realities of the universe. The lectures assume a rather sophisticated knowledge of physics and mathematics. The authors present alternative views on approaching a formulation that fully accommodates both quantum and gravitational (general relativity) theories in physics. One question, for example, is whether parameters in a quantum description of matter can have definite ("real") values before they are measured. The issues extend to cosmological implications and have intriguing philosophical as well as technical aspects. Although well done, the treatment in this book is not for the general reader.
