Time is among the universe's greatest mysteries. Why, when most laws of physics allow for it to flow forward and backward, does it only go forward? Physicists have long appealed to the second law of thermodynamics, held to predict the increase of disorder in the universe, to explain this.
In The Janus Point, physicist Julian Barbour argues that the second law has been misapplied and that the growth of order determines how we experience time. In his view, the big bang becomes the "Janus point," a moment of minimal order from which time could flow, and order increase, in two directions. The Janus Point has remarkable implications: while most physicists predict that the universe will become mired in disorder, Barbour sees the possibility that order — the stuff of life — can grow without bound.
A major new work of physics, The Janus Point will transform our understanding of the nature of existence.
I RECEIVED A DRC FROM THE PUBLISHER VIA NETGALLEY. THANK YOU.
My Review: On the Solstice, I think a lot about time. Why time's arrow only points in one direction, for example. I am always bothered by the implication inherent in the laws of physics that we presently understand that this is an observational artifact, not part of the structure of physics.
While I sit and ponder the strange dichotomies between what we observe and what theory tells us is possible, Author Barbour sets himself the task of learning the why, and questioning the how, of all the factors in physics that determine this issue's boundaries. That is an immense task.
It is also one well beyond most people's educational, vocational, and experiential capacities. The author isn't writing an academic paper in this book. He is, however, presupposing a lot of knowledge on the reader's part...if you don't know what a Boltzmann brain is, for example, this book will be lost on you...and even for those with the requisite grounding in at least the people who created the outlines of the Standard Model of particle physics, the need for frequent research breaks, aka "fallings down the many rabbit holes", is ever-present.
Very much not a Wikipedia-level treatment of an immensely important topic being argued, studied, researched, and pondered by some of the best-furnished minds in the field of physics today; yet it does not repel boarders with its case-shot loaded cannons of erudition. Author Barbour is quippy and quotable. The problem is quoting him won't help. This is someone with a very broad grasp of physics, history, cultural anthropology, etc. He lays out arguments that I suspect I only dimly grasp for his new model of endlessly repeatable order, ie creation of matter instead of its inevitable and complete decay, grounded in all the currents of thought there are.
Not, as you'd expect, a mere bagatelle to be consumed of an evening. Took me two years to read it, and I regret not a page or a minute of it. I was rewarded with a greatly expanded idea of what the science of physics is reaching for in its quest for a unified theory.
At this #Booksgiving moment, self-gifting this immensely challenging and deeply absorbing book is a great way to invest in your brain's expansion in entirely new ways and directions. It will be a Project. It is also well worth your eyeblinks.… (mais)
