Product Description

In Time Reborn, Lee Smolin, one of our foremost physicists and thinkers offers a radical new view of the nature of time and the cosmos

Nothing seems more real than time passing. We experience life itself as a succession of moments. Yet throughout history, the idea that time is an illusion has been a religious and philosophical commonplace. We identify certain truths as 'eternal' constants, from moral principles to the laws of mathematics and nature: these are laws that exist not inside time, but outside it. From Newton and Einstein to today's string theorists and quantum physicists, the widest consensus is that the universe is governed by absolute, timeless laws.

In Time Reborn, Lee Smolin argues that this denial of time is holding back both physics, and our understanding of the universe. We need a major revolution in scientific thought: one that embraces the reality of time and places it at the centre of our thinking. E may equal mc squared now, but that wasn't always the case. Similarly, as our understanding of the universe develops, Newton's fundamental laws might not remain so fundamental. Time, Smolin concludes, is not an illusion: it is the best clue we have to fundamental reality. Time Reborn explains how the true nature of time impacts on us, our world, and our universe.

'The strongest dose of clarity in written form to have come along in decades. The implications go far beyond physics, to economics, politics, and personal philosophy. Time Reborn places reality above theory in stronger and clearer terms than ever before, and the result is a path to better theory and potentially to a better society as well. Will no doubt be remembered as one of the essential books of the 21st century' Jaron Lanier

Lee Smolin is a theoretical physicist who has made important contributions to the search for quantum gravity. Born in New York City, he was educated at Hampshire College and Harvard University. Since 2001 he is a founding faculty member at Perimeter Institute for Theoretical Physics. His three earlier books explore philosophical issues raised by contemporary physics and cosmology. They are Life of the Cosmos (1997), Three Roads to Quantum Gravity (2001) and The Trouble with Physics (2006). He lives in Toronto.

5.0 out of 5 stars Real eye-opening science speculation 2 Jun 2013
By B. M. Clegg TOP 1000 REVIEWER
Lee Smolin's book is largely accessible (more on this later) and simply mind-boggling in its scope. What he does here is take on time, and specifically the position of time in physics. Even taken as a simple book on time this is brilliant. The fact is, the majority of books that claim to be about time tell you nothing. It's striking that A Brief History of Time tells us that amongst a list of deep scientific questions that have answers suggested by `Recent breakthroughs in physics, made possible in part by fantastic new technologies', is `What is the nature of time?' But you can search the book from end to end for any suggestion of what time is or how it works. There is plenty on how we observe time, and how interaction with matter can change these observations, but nothing deeper.

Smolin gives what is, for me, the best analysis of the nature of time from a physics viewpoint in a popular science book I have ever seen. He goes on to describe how most physicists consider that `time does not exist', and comes up with an approach where time becomes real in physics. Now I do have one issue with Smolin here. He says that amongst his non-scientific friends `the idea that time is an illusion is a... commonplace.' This is garbage (or at least his friends are non-representative). The vast majority of people who aren't physicists or philosophers would say `Of course time exists.' However, Smolin sets off to first persuade us it doesn't, using the most common arguments of current physics, and then to show how this is a mistake.

In fact, I think the reason most people wouldn't agree is because it isn't really true that modern physics says time doesn't exist.

4.0 out of 5 stars Provocative and brave 24 May 2013
Lee Smolin has truly made a book that does make you think very differently about time. His arguments are provocative and perhaps controversial but that is a good thing. I love that his emphasis is always on making his theories as amenable to experiment as possible. Having read the book I am especially swayed by his arguments about trying to build a cosmological theory that is not based on what he calls the "physics in a box" theories which always involve boundary conditions. The most important thing about this book is that it is easy to read and engaging. Another reviewer was horrified that he was promoting a nonlocal hidden variables theory, but at least he has made a justification for it and his focus is always in trying to build such a justification for a new theory that will be experimentally falsifiable. I also rather like his ensemble-interpretation of quantum physics because it at least is trying to make the theory based on real-ensembles. Almost throughout the book this falsifiability is his main commitment, and if it was throughout the whole book then I would have given it 5 stars. However, he recapitulates in the epilogue and claims that there are things that are probably "intrinsic" and "essence-like" and seems to hark back to dualist and unfalsifiable theories of consciousness. Though this is a tiny section of the book it scares me that he would build such a wonderful relational justification for the universe and then discard it because he can't "see" how consciousness would fit into it. He drives a difficult path through the mire and then seems to jump on an easy one at the end for a bit of light relief! Read more ›

4.0 out of 5 stars A radical new view of time. 22 Jan 2014
Format:Hardcover|Verified Purchase
The aim of the book is to restore time to its `rightful' place as a `real' quantity in the description of the universe. For most readers, and also most scientists (despite what Smolin says) time is already `real'; we observe its passage daily as things, including ourselves, decay. On the other hand, there is the paradox that although we live `in time' we commonly judge our activities by timeless standards; Smolin gives `truth' and `justice' as examples. In the scientific context, what he means is not that the laws of nature don't contain a time variable, because some of them obviously do, rather the form of the laws themselves are timeless. Newton's laws of motion are the same now as when he discovered them and will remain so indefinitely; that is the assumption on which physical science at present is based. Progress within this framework is made by making improvements to experiments and treating the outcomes as timeless. Smolin starts by reviewing how this has become the orthodox view.

Smolin believes that the orthodox view is an illusion that stems from a common belief (the Newtonian paradigm) which assumes we can predict the future state of any system from its initial conditions and the laws acting on it and, crucially, that this can be extended to the universe as a whole. One consequence of this is that the universe would ultimately reach equilibrium where entropy is maximized and a universe such as ours could occur only briefly as a random fluctuation, which leads to some very weird predictions and essentially renders scientific research pointless. Smolin believes the Newton paradigm is a fallacy, because in practice physics deals with closed systems, and we have to accept that the laws as we know them are approximations.
