Mathematician Roger Penrose’s book “ The Road to Reality: A Complete Guide to the Laws of the Universe” (2004) ISBN 0-679-45443-8; OFL Library location: QC20.P366 2005 is a blast! There is so much to say about this magnificent encyclopedic account of the history and philosophy behind the most important discoveries of humankind. So much that I will not try.

To get a taste of the one-thousand-page book you have to only look at the content.

1. The Roots of Science

2. An Ancient Theorem and a Modern Question

3. Kinds of Numbers in the Physical World

4. Magical Complex Numbers

5. Geometry of Logarithms, Powers, and Roots

6. Real-Number Calculus

7. Complex-Number Calculus

8. Riemann Surfaces and Complex Mappings

9. Fourier Decomposition and Hyperfunctions

10. Surfaces

11. Hypercomplex Numbers

12. Manifolds of n-Dimensions

13. Symmetry Groups

14. Calculus on Manifolds

15. Fibre Bundles and Gauge Connections

16. The Ladder of Infinity

17. Spacetime

18. Minkoiskian Geometry

19. The Classical Fields of Maxwell and Einstein

20. Lagragians and Hamiltonians

21. The Quantum Particle

22. Quantum Algebra, Geometry, and Spin

23. The Entangled Quantum World

24. Dirac’s Electron and Antiparticles

25. The Standard Model of Particle Physics

26. Quantum Field Theory

27. The Big Bang and its Thermodynamic Legacy

28. Speculative Theories of the Early Universe

29. The Measurement Paradox

30. Gravity’s Role in Quantum State Reduction

31. Super-symmetry, Supra-Dimensionality, and Strings

32. Einstein’s Narrower-path; Loop Variables

33. More Radical Perspectives; Twistor Theory

And finally

34. Where Lies the Road to Reality.

If you are interested in paradox, language, ontology or semantics this is the book for you! It looks like it is only about mathematics but it is not. Written for the general public, it doesn’t require you to be proficient in math even though formulas are used in order to clarify the semantic connection of reality with concept. In fact I recommend this reading to those who have had bad experiences with math. Penrose is one of the clearest minds alive today and his writings in Mathematical Physics directed to specialists, as well as his writings directed to the general public have become classics.

### No Time at All

As I try to write at least once a day. It shows that I have not been successful, It is more like once a month. Time is scarce. No writing but a lot of reading! One book: Yourgrau's "A World Without Time" is an account of the friendship between Godel and Einstein comes to my point about not having time as Godel's hypothesis is that "time doesn't exist."
