Needs a Newer Update

Revisado: 07-13-19

Good investment advice from 1960s to early 2000s. Needs an update as last update was almost 20 years ago, pre-financial crisis.

Not His Best Book

Revisado: 08-23-18

I've read all of Rovelli's books, and this is his not his best book. Much like his description that details are blurred to create time, the different topics are blurred to create this book. A blurring of philosophy, quantum physics, relativity, thermodynamics, and psychology. Cumberbatch's reading is good, but the story is not clear and brief like Rovelli's usual work. The use of footnotes is particularly annoying. If it is pertinent, say it in the body of the material, if it isn't, leave it out.

Fundamentally Strong

Revisado: 01-20-18

Backed by research that meets common sense. Stress + Rest = Growth. Good details on how to do both and WHY. The goals and purpose part could have been left out, as this book met the objective of tactics. Inspiration is important motivator, but there are lots of books about motivation.

Appendix is best

Revisado: 01-01-18

Good life and work principles that most people try to follow. The tools in the appendix (dot collector, baseball cards, process diagrams, problem list) are specific things for implementation. The 5 step goal setting process is also good, as well as the delve into high level neuroscience and plasticity and habits. Book will probably be more educational for those who are distractible or lack structure, while those who are already detail oriented will find it a good refreshing review of a top down approach. Nothing really new in this book that people haven't heard already, but it is a good collection of practical principles in detailed outline and put to use.

Good Start, Stumbling Finish

Revisado: 11-26-17

Enjoyed the message, but a lot of lecture and "preachiness" at end. Action scenes are entertaining, but unnecessary.

Great synopsis

Revisado: 11-10-17

Great summary of our species' mental concoctions, achievements whether by luck happenstance or force, deficiencies , and potential.

Advertised as controversial, and I'm sure there are some bigots in the world who would say so, but I found nothing controversial, only truth and fact.

Best Physics Book of Last 5 Years

Revisado: 02-14-17

Great book, presented in very simplified understandable terms of complex subjects. Really liked his humble dialog, and suggestion that merging of quantum mechanics, relativity, and entropy will be needed to make a complete model of the nature of the universe and matter.

Good Start, Fast Finish

Revisado: 12-29-16

The first 3/4 of the book do a good job of explaining and developing conceptualization of the quantum world and the quantum wave function. Then it started moving fast when talking about tunneling and entanglement to the point that last few chapters were not nearly as comprehensible. I probably need to listen to last half of book again.

A Lot of Philosophy

Revisado: 12-09-16

Comprehensive integration of numerous fields. I found it informative but also forgetful. For someone who has never taken a formal course in philosophy, I found it too much. It seemed to drone on about philosophical history and arguments. Even though he argues probabilities, it seems to present some physical theories as almost certain, even though there are more recent discoveries that suggest it isn't so. For instance, the Big Bang and Cosmic Microwave background. A recent statistical analysis of the data suggests that the universe is not expanding at an accelerating rate, nor was there a Big Bang. For an atheist to accept a creationistic Big Bang theory so readily is concerning. Maybe the universe is already at equilibrium as Hoyle and Einstein argued, and there are other theories for the continual creation and destruction of matter and apparent expansion of the universe that meet the conservation laws of physics. I would have liked him to address Penrose's theory on the cycles of time and entropy a little more thoroughly, as Penrose has difficulty explaining things in layman's terms like Carroll does so well.

I need someone to explain inflation to me in understandable terms, because I just don't see how space can expand faster than the speed of light, nor do I see what drove inflation If the theory is true. This book didn't answer that clearly for me.
