A Brilliant Look at Real Science

Some very good books on science focus mainly on detailing a particular scientific discovery or discoveries. Some very good science books do their best to communicate with a general audience concerning ideas that can be highly technical. What is rarer is a science book that does both of these within the framework of what it is really like to live and work as a scientist. The amazing book The Double Helix by James Watson which describes the quest for the structure of DNA is one of these. So is this book by Alan Guth on the development of the inflationary universe theory as a "correction" to Big Bang theory.In this book Guth takes us through the basics of the Big Bang theory and then into the idea of inflation--what it is and how it goes along with Big Bang theory. He takes a wonderful historically-developed approach and he does this without the help of (at least as far as I can recall) a single equation in the body of the text. Instead, he uses basic numerical analysis and the help of a number of graphs and illustrations to develop these complex ideas into a very readable explanation. He is also very frank in warning the reader of difficult concepts and directing the less detail-minded to skipping around.All of this makes for a good science read; however, what I really enjoyed about this book is how he brings out the things that really drive real science, particularly when he reaches those investigations into which he was personally involved. He points out how theory and experiment drive each other. He isn't afraid to show the fights for priority and reputation that often push scientists. He lets us see how the desperation for a secure job, the cockiness of the young researcher and the ego of established names is often the engine for discovery.Anyone interested in the current state of research into the origins of our universe would be remiss in not reading this book. Many people get the gist of Big Bang theory but fewer understand what Big Bang theory is really about and fewer still understand why the inflationary universe has become so important in recent years. This book will clear away all the fog; in particular, Guth is very clear in explaining the problems with Big Bang theory (the horizon problem, magnetic monopoles, etc.) that are cleared-up with the inflation approach.More than this, however, the reader will gain real insight into what it is like to be a working scientist. It offers a peak at its excitements and disappoints, even a glimpse at the clashes and in-fighting. Many people often get the idea that science makes grand pronouncements of fact from on high. This book shows that science is, in reality, a continuing struggle for a more and more accurate picture of our universe and how it works. It is a view worth seeing.

Another example that simplicity is beauty

Dr. Guth has written a beautiful account of seperate stories. The first story is the tale of how he discovered the theory of "universal inflation." The second story is the brief history of particle physics. The two seperate story lines converge in his explaination of the theory of inflation. While some concepts may be difficult for the layman to visualize, Guth's easy tone and coherent style will pull the reader past worries and into "quantum" understanding. While some people still question inflation, I believe the true beauty of this theory proves that it must be at least close to the truth. Often, the correct theory seems impossible at first, but once it starts solving problems it never dealt with, simplifying the truth, it becomes that much more persausive an argument. Give it a try even if you don't think you can read it all. And even if you want to quit, skip ahead and skim the last two chapters - the titles alone will make you want to read.

Origins of the Universe

I always enjoy reading books about scientific discoveries by authors who were there. Alan H. Guth's book "The Inflationary Universe" not only provides a revealing look at the development of inflationary theories of the universe, it is by far the best explanation on the subject that I've seen for the general scientifically literate public.Guth starts almost at the beginning of modern science by laying a foundation of understanding in conservation laws and fields. His explanation (supported by further information in an appendix) of the negative energy of gravitational fields is clear and intuitive. So clear are his explanations that one hardly seems surprised when Guth introduces Edward Tryon's early speculation that the universe may have originated from a quantum vacuum fluctuation. Next, Guth develops the idea of an expanding universe, and the flatness problem. His explanation of why the flatness problem is a problem at all is concise and wonderfully illustrated. Throughout all of this, Guth offers a rare glimpse into the workings of science by showing the chaotic effects of unpredictable chance occurrences that lead to that rare insight with its attendant "ahhhh" at the end of discovery. I particularly enjoyed the photographs he included of many key players in the developments of modern cosmology, with a singular exception. There is no photograph of Guth himself [this is my only complaint about the book].Leading up to the discussion of inflation proper, Guth offers clear and insightful discussions of the discovery of the microwave background radiation. He offers rare insights into the extraordinarily difficult measurements that led to the first discovery, culminating with the superb measurements and confirmation provided by COBE in 1990. As further preparatory information, Guth offers one of the best general-purpose science explanations I've seen for the particles in the standard model, including some very good descriptions of the Higgs particle, which plays a central role in the theory of inflation. Guth is proof that complicated theories can be reduced to simple ideas without losing the essential logical constructs that make them work.The second half of the book deals with inflation proper. Here, Guth explains how inflation solves the flatness problem, and deals with such things as monopoles, and the nearly uniform background radiation. The end of the book deals with the aftermath of discovery, and the problems with inflation yet to be ironed out. The author discusses many esoteric possibilities, including percolation of false-vacuum bubbles, event horizons, and pocket universes.If the origins of the universe excite your intellectual fancy, I highly recommend "The Inflationary Universe."

The best and deepest popular book on cosmology available

Wow! What a great book. This is the clearest and deepest book on cosmology for the layman that I have ever read, and I've read a lot of them. I don't know whether previous books I've read just didn't explain it right or what, but before I reading this book, I was always disgruntled by inflationary theories of the universe, thinking for some reason that they were ad hoc, devised out of the blue to explain the flatness problem. This is the first book on the subject that I've ever read that showed me that inflationary theories are actually derived from more basic theories, and that they just HAPPEN to explain several different problems associated with the classical big bang theory. I was also very intrigued by Guth's explanation of how there is probably a fractal pattern of universes similar to our own that emerges out of the decay of the false vacuum. This is also the first time I've understood that the "multi-universe" proposals really ARE based on scientific theories, and weren't simply pulled out of thin air. A wonderful book that make a host of other books on cosmology look amateurish by comparison
