Nov 18, Michael Connolly rated it it smllin amazing Shelves: Now, in Time RebornSmolin attempts to chip away at basic theories of modern physics. I thought this was one of the most interesting ideas in the book, since it seems to provide a way around one of the main roadblocks to the reality of time, namely the relativity of simultaneity.
Time Reborn by Lee Smolin – review
A Caltech archive has the text of what Feynman says there: Buddhism seems to acknowledge the play of opposites I’ If you’re into stuff like this, you can read the full review.
At rebotn end of Time Rebornthe reader will not have a pet cosmological theory or an answer to why quantum mechanics fails to scale up past the microcosmic level.
Sep 10, Christy added it Shelves: CDT has a preferred time smooin at least a preferred foliation, and is built up in layers with a certain thickness. So the main idea is not to reject timeless law, expressed in partly mathematical language, it is to find more elegant description and more economical explanation. Recognising the yin-yang nature of the universe, in order to claim there is constant ‘flux’ fluidity, rather than change; a subtle difference – or for argument’s sake, change – Buddhists balance that revorn asserting a ‘greater’ reality – the one, eternal, stable, whole a supposed ‘deeper’ reality.
April 29, at 7: That’s why, Smolin goes on to say, time appears simply as one optional parameter in physical calculations based on math that is time-reversible–whereas everyday experience and the Second Law of Thermodynamics tell us that time is both real and irreversible. On a universal scale there is a constant ler.
To add to this the idea that we might live in the universe in which there is no space, just a network of interactions, with everything potentially connected to everything else – this makes the whole book an enticing journey of new discoveries and the universe a very interesting place to live in. In essence physics is in trouble. Jul 02, Zoe Jackson rated it it was ok.
Smolin has an awesome idea, first printed in his excellent book The Life of the Cosmos. Hardcoverpages.
I thoroughly enjoyed Time Reborn, and have a lengthy gime of other books to investigate thanks to the endnotes and bibliography.
He really brought me back to my high school days when my physics teacher just kept mumbling to himself, writing on the blackboard.
Time Reborn – Wikipedia
The one area that really raises questions for me is precedence: Some of the most interesting chapters in this book are those in which Smolin traces the history of what the philosopher Edmund Husserl called the “mathematisation of Nature”. Quantum mechanics cannot be taken as universal, because it only applies to the small subsystems we experiment on.
But, mathematical laws need not be physically lying outside of the universe — they are mental products, and thus of a different category from the physical universe. Plato’s timeless mathematical world. Here in the real world, it is always some time, some present moment.
It’s a point that people should take seriously, whether they’re thinking about physics or some other field. Some quotes Smolin begins with on p. Compare a two dimensional neighborhood of houses with a three-dimensional apartment building: A message for Lee: How does a particle know what laws apply to it or how to follow them? Conservation laws, such as the conservation of energy, are fundamental to physics. The problem, of course, is that it ignores the basic premise of the anthropic argument: Smolin ends with a vision that is pretty much the exact opposite of mine, one with a vastly diminished role for mathematics in understanding the nature of reality: Where was the editor when they were needed?
