Lee Smolin
In Three Roads to Quantum Gravity, Lee Smolin provides an accessible overview of the attempts to build a final "theory of everything." He explains in simple terms what scientists are talking about when they say the world is made from exotic entities such as loops, strings, and black holes and tells the fascinating stories behind these discoveries: the rivalries, epiphanies, and intrigues he witnessed firsthand. Written with exceptional style and clarity, Three Roads to Quantum Gravity confronts the deepest questions of the nature of the universe and provides a preview of some of the remarkable scientific developments we can look forward to in the 21st century.

Fascinating story

I had purchased this book without realising it was written prior to his 2006 book. It becomes quite evident that the author is struggling to reconcile theories which are not testable and therefore unable to be falsifiable.
Can science produce work that no one can conceive experiments for testing them. In this book Smolin is still optimistic, but what else can a person who spent most of his life think. I believe there is more hope than reality. Physicists are satisfied with mathematical theories that explain reality and less concerned with experiments at this scale.
The book explains three roads to quantum gravity, an effort to unify quantum theory with relativity, but the roads could very well be more than three, and very long indeed before any unifying theory can be experimentally tested.
The author writes well on subjects that are usually nearly impossible to understand, and for this I must give him credit. Recommended to those that want to understand today’s complicated physics without mathematical knowledge.

Looping- pun intended- and cycling through dated and sometimes plain gross analogies such as cats eating yummy or yucky mice (yuck!!) I learn nothing substantial and thought provoking after 2 hours of listening- abandoning this. Waste of a credit.
Waste of time after listening to Prof. Don Lincoln
