It's been nearly a decade since Roger Penrose wrote "The Road to Reality." This weekend, I finally finished the book. (I had read individual chapters here and there, but I finally found the time to sit down and read the whole book.) The reason that I finally forced myself to read the whole book is that I wanted to see how many of his speculations in 2004 are still valid today. Also, Roger Penrose has some very interesting ways of describing mathematical theories, and he recognizes the ad hoc and incomplete nature of the current "Standard Model," but doesn't shy away from stating his negative opinions about supersymmetry and string theory.
The book is a breath-taking overview of fundamental physics and geometry from the perspective of a Platonist. What's refreshing about the book is the fact that it's a history of physics and mathematics from the view point of a Platonist (i.e. somebody who believes that mathematics...and perhaps beauty and morality...are eternal, unchanging, and exist eternal to the material and mental world.)
Three worlds, Three mysteries p20&1029 "The Road to Reality."
What makes the book so refreshing to read is that, in the decade since this book was published, the "physics media" (i.e. Sean Carroll, Lawrence Krauss, Brian Greene, Martin Rees. Leonard Susskind, and others) have attempted to dismantle neo-Platonism and a belief in an unchanging, external world of absolutes. Post-modernism infected most of the social sciences in the 50s-70s, but physics and mathematics were still holding strong against post-modernism and relativism until the 2000s, at which point in time, the "physics media" began hyping string theory, supersymmetry, multi-verses, universes from nothing, randomness, inflation, time symmetric laws of physics, and the quantum randomness. Luckily, as "natural" string theories and supersymmetries have faced an timely demise due to falsification by high-energy particle collider experiments, it's easier to see that the emperor has no clothes.
