Publisher's Summary

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.

Beautiful narration. Tough subject matter!

Beautiful narration. A very well-written history of some of the most intellectually challenging concepts related to Quantum Theory and Einstein's General Theory of Relativity. Full of drama and anecdotes from a life in the quest for the elusive theory of Quantum Gravity. Makes you wish that you had a degree in science and then come to this, and not a literature student!

A great overview.

I really enjoyed my first run through. The overview of current thinking is accessible and informative. It also left me with a sense of progress that the field of quantum cosmology is making. We are at an exciting point and Smolin conveys this excitement very well.
I will listen to this a few times, I imagine, and glean more from it on each occasion.
Highly recommended!

Physics still in trouble

I first came across the author Lee Smolin through his 2006 book, The Trouble with, which I thought deserved merit, because it highlighted the detachment of modern particle physics from reality and criticising the ever elusive and continuously evolving mathematical hypothesis of string theory.

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.

Rambling

I found this too rambling for my taste. I only listened for 2 hours, maybe it became more focused.

The actual publication date is 2001

The publication date is misleading, there is only about 45 minutes of content at the end of the book in the form of a post script that is within the last year of 2018, most of the book was published over 15 years ago

Fascinating story

very balanced portrayal of several research paths. Altuogh he is very clear about which path he feels is best. Great book overall
