FROM ETERNITY TO HERE: THE QUEST FOR THE ULTIMATE THEORY OF TIME FREE DOWNLOAD

Since everything is far more likely to be in a high-entropy condition than a low one, it remains a mystery why the universe currently has relatively low entropy, and apparently had even less in the past. Naturally, there is no dearth of principled suggestions that attempt to avoid the necessity of assumption e. I guess I am not exactly known for my patience In fact, the questions are so grand, and so monumental, Carroll can't help but comment on the scope of modern physics from classical mechanics and relativity to the absurd realities of quantum mechanics. The Great Unknown. B: A camera takes pictures of things that happened in the past. Its speculations on time travel and wormholes and multiple universes gave my inner sci fi geek plenty to chew on. Great read, under proper expectations. The Physics of Everyday Things. In the book, Carroll explores the nature of the arrow of timethat goes forward from the past to the future, and posits that the arrow owes its existence to conditions before the Big Bang. In one, expansion continues without end. Aug 28, Marc rated it it was ok Shelves: sciencephysicsquantum-mechanics. Where Carroll sees this as the driving of time one way, a 'power' gradient can be also seen to lie at the heart of the cosmos as it moves from disequilibrium concentrated energy or power to equilibrium states dissipated energy where there is no power. View 2 comments. The only way to understand the origin of entropy is to understand the origin of the universe — by asking what happened at the Big Bang, and even before. View all 9 comments. That implies that they have entropy, and that they will From Eternity to Here: The Quest for the Ultimate Theory of Time evaporate away. The prologue is reprinted here, to provide an overview of the themes of the book. More videos One of those purposes - among many - stems from our urge to explain the world around us the best we can. Add links. The book is richly sprinkled An honest, fascinating and surprisingly engaging book about the enigmatic concept of time and its relationship with other equally perplexing concepts of Entropy and Big Bang. James Bridle. For the most part. Dec 21, Peter Pete Mcloughlin rated it it was amazing Shelves: favorites, nukes-and-the-end-the-worldgeneral-sciencebiologygood- thingsnonfictiontotohousehold-items. Return to Book Page. He consistently refers to high and low entropy and when this is deciphered more, low energy means order, and order means From Eternity to Here: The Quest for the Ultimate Theory of Time high entropy means disorder and equilibrium. Unlike space, time has only one direction. At this point, the curren If I am tracking his argument accurately, Carroll is saying in this book that change, as time, is eternal. The book is about time. Carroll views the Big Bang model working well as we look backwards until we reach the singularity at which point the laws of general relativity break down. Looping Through Time Closed timelike curves would allow you to visit the past without violating the rules of relativity. In From Eternity to HereSean Carroll argues that the arrow of time, pointing resolutely from the past to the future, owes its existence to conditions before the Big Bang itself, a period modern cosmology of which Einstein never dreamed. Just a couple of areas where I found areas for improvement: - in the treatment of quantum mechanics, the collapse of the wave function is correctly regarded by the author as a potential problem of the so-called "Copenhagen interpretation": this is correct, but there are other interpretations in particular, the DeBroglie-Bohm theory that overcome this problem yes they are non-local, but the author himself actually tends to agree with the From Eternity to Here: The Quest for the Ultimate Theory of Time position of this and similar approaches - so a even brief mention of these alternatives would have made the book much more complete - whilst the concept From Eternity to Here: The Quest for the Ultimate Theory of Time symmetry is very nicely illustrated and explained, unfortunately the very important concept of symmetry-breaking is not explained - which I think is baffling in a book which is supposed to deal with time reversibility and the arrow of time. Mostly As: From Eternity to Here: The Quest for the Ultimate Theory of Time are a normal person. He told me it was very good to get a better understanding of the Universe and the role of the arrow of time in it. So he developed this weird theory with his girlfriend? B: But why not? But the answer remains elusive. Trivia About From Eternity to Alan Lightman. Wall Street Journal. Bottom line: this is a first-rate piece of popular science writing. A Beautiful Question. Entropy is a key concept, which deserves and gets lots of attention. However as I finished the first third, the book started to become hard to follow and I eventually stopped reading by the middle of it. Is Our Universe Natural? This book has by far the best description of general relativity especially the equivalence principle for the non-physicist that I have ever encountered. Jul 21, Todd Martin rated it it was ok Shelves: environment-science. Lists with This Book. The Code Book. This is a lot of ground to cover and the man refuses to use any equations! I thought Carroll padded the laying out of the problem and why it is a problemand he's another author who has a tendency to make cute, folksy, annoying asides but if you're interested in cosmology this is a book worthy of your unrecoverable time. Epilogue The origin of the universe and the arrow of time are major unsolved problems in our understanding of the natural world. As a reader, you really can't help but be infected by Carroll's own excitement and optimism that science will ultimately unlock even the deepest mysteries of where we came from and where we're going. Goodreads helps you keep track of books you want to read. Sean Carroll shows why the reversibility of physics at the particle level gives rise to a seeming paradox; if the physics of particles is just as correct with time switched backwards, why can't entropy decrease? Get A Copy. Maybe the reason we observe such crazily low levels of entropy is because our universe is just a toddler.
