"Simply astounding. . . . Gloriously variegated. . . . Pure delight. . . . It is shocking that so much can be explained so well. . . . Penrose gives us something that has been missing from the public discourse on science lately-a reason to live, something to look forward to." --American Scientist

"A remarkable book . . . teeming with delights." --Nature

"This is his magnum opus, the culmination of an already stellar career and a comprehensive summary of the current state of physics and cosmology. It should be read by anyone entering the field and referenced by everyone working in it." --The New York Sun

"Extremely comprehensive. . . . The Road to Reality unscores the fact that Penrose is one of the world's most original thinkers." --Tucson Citizen

"What a joy it is to read a book that doesn't simplify, doesn't dodge the difficult questions, and doesn't always pretend to have answers. . . . Penrose's appetite is heroic, his knowledge encyclopedic, his modesty a reminder that not all physicists claim to be able to explain the world in 250 pages."
--The Times (London)

"For physics fans, the high point of the year will undoubtedly be The Road to Reality."
--The Guardian

"A truly remarkable book...Penrose does much to reveal the beauty and subtlety that connects nature and the human imagination, demonstrating that the quest to understand the reality of our physical world, and the extent and limits of our mental capacities, is an awesome, never-ending journey rather than a one-way cul-de-sac."--London Sunday Times

"Penrose's work is genuinely magnificent, and the most stimulating book I have read in a long time."--Scotland on Sunday

"Science needs more people like Penrose, willing and able to point out the flaws in fashionable models from a position of authority and to signpost alternative roads to follow."--The Independent
