For en strålende enkel og lesbar bok som forklarer det komplisere så jeg nesten forstår det, og det at jeg nesten forstår er poenget: Å forstå helt er umulig, men vi nærmer oss stadig helt til det dukker opp noe nytt som gjør det vi forstår enda litt mindre forståelig. Må leses av alle, og spesielt av folk som tror de vet.

A good summary of discovery of quantum mechanics, and also, a very gentle introduction of Loop Quantum Gravity. Experienced people may see the explanations are too simple, it is very broad and abstract. However, this is actually perfect for starters like me, warming-up my brain to another bizzare theory quantum gravity.
This hurts my brain. Listened to the audiobook. I need to read this cause I missed a lot.

I feel like I'm not smart enough to understand this - the concepts in here are mindboggling and great material for an existential crisis.
Physics A-level padded the brute descent into quantum physics, I think my mind would've actually combusted if I already didn't know some of the basic theories. The middle section lost me for a minute (I still don't really GET special or general relativity) but the hopeful tone throughout kept me going. I am definitely going to read this again after my studies (hopefully older and wiser) to see how much more I'll understand.

Oh my gosh what a wonderful book. Extremely accessible, almost like a love letter to physics in some ways. I absolutely loved it.
This was totally over my head and although I enjoyed the parts I kind of understood, Rovelli’s assurance that this book is written for someone who doesn’t have a background in physics is not accurate. [b:Seven Brief Lessons on Physics|25734172|Seven Brief Lessons on Physics|Carlo Rovelli|https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1443551746l/25734172._SY75_.jpg|42912214] is by far the superior book.
I was very skeptical going into this that Loop Quantum Gravity could actually bridge the gap between General Relativity and Quantum Mechanics. And though I'm hardly qualified to evaluate whether or not that gap has been bridged, Rovelli presented a plausible and compelling case for the coherence of LQG in a field that for 80 years has valued the exotic over the intelligible. The current alternative, String Theory, suggests 10-26 dimensions for reality; LQG just the usual 3, or 4 if you consider time to be one. String Theory fiddles with infinities, an absurdity in reality; LQG needs no infinities. I'm not a believer yet, but I'm going to turn my chair Rovelli's way and grab some popcorn, because this could be good.
The book ends with a chapter beautifully written about the mysteries of discovery, of doubt, and progress, and gently but sagaciously warns against dogmatism and authoritarianism. I found it quite moving.
*Second reading
The second time through I still enjoyed this book a lot, especially Rovelli's eloquence, but I changed my rating from 5 stars to 4 because parts are unnecessarily opaque and cryptic (wtf are clouds of improbabilities but abstractions?). Still, there was so much in here that I'd forgotten, and the discussion on heat and information theory was articulate and, from my perspective and learnings over the last year, still relevant.
Here's to doubt and discovery.
*Third reading
Still a great book, much more comprehensible than many books on physics, although still unnecessarily opaque in certain areas. The last chapter is still my favourite.
