4.0 out of 5 stars A Piece of Scientific History, December 14, 2002

By	John Vickery (Memphis, TN United States) - See all my reviews (REAL NAME)

Galileo's Dialogue Concerning the Two Chief World Systems has long had its place in the history books. The work consists of a dialogue between three characters, Salviati, Sagredo, and Simplicio. They gather together over the course of four days to discuss the Ptolemaic and Copernican views of the universe. Ptolemy's system is that of an earth centered universe that aligns with the views of Aristotle, the more popular conception. Copernicus's system is heliocentric. This is a radical opinion of the time and incidentally is the correct one. Salviati supports the Copernican system and Simplicio adheres to the Ptolemaic view. These two refute the ideas of the other and argue for their own. Sagredo is somewhat caught in the middle. However, he ultimately aligns with Salviati on every point. The translator, Stillman Drake, in his introduction, goes over the climate and political forces of Galileo's day along with Galileo's reason's for writing this book. As Drake points out, Galileo is appealing to the public here. It seems that this is Galileo getting in the last word on the argument for a heliocentric universe. This book is also what largely does him in with the Vatican. Galileo dose not directly argue against the church in this book but only against the Aristotelian opinion while showing reverence for divine power.

The best was to describe this book is verbose. It fills 465 pages with small print. Because it is written in conversational tone, perhaps Galileo felt that the extra wording was necessary. It does take some time to read. Drake does an excellent job of making important notes throughout the work. Some of these are geared more for an academic study, but others give needed explanation. Just like we do not have all the answers today, Galileo makes some scientific mistakes. These are few and Drake gives explanations for them. This book is worth the read for its place in history. A brief background in astronomy and even Aristotelian philosophy will benefit the reader. I would also recommend Discoveries and Opinions of Galileo, also translated and compiled by Drake.

5.0 out of 5 stars a lovely book, April 11, 2003

By	Glenn Becker (Arlington, MA USA) - See all my reviews (REAL NAME)

To read this book is to see the Western Mind open to light and fresh air after centuries of stale darkness. This is not to snub the monumental work of Aristotle or Ptolemy but to rue the fact that their writings were clung to as doctrine for so long.

Even in translation, Galileo is a lively, robust, even funny writer. His fiery spirit is especially welcome in these troubled opening years of the 21st century: I kept marking pages for later reference. Some parts of this great book will require work on the reader's part, but the work is so eminently worth it. This edition has copious, interesting notes, too, which make the adventure an even more colorful and full one.

This is no "great grey classic" to be endured, but a living bronco of a book: relevant, ferocious, and of great historical and scientific interest.

5.0 out of 5 stars Excellent Edition, April 14, 2001

By	eric zazie (Yabadabadoo) - See all my reviews

The book is well done, I like the type, the notes are informative, the preface by Einstein is by Einstein, and Drake inserts the Italian phrase at the right moments. The book itself is not read as much as it should be--it is an excellent introduction to the history of science and cosmological thought, and an informative specimen of the rhetoric of science at the very moment that rhetoric is derogated by Galileo. For instance, Galileo borrows the valorization of circular motion from Plato and Aristotle (Galileo sides with Plato against Aristotle) and argues that all motion is circular, even freefall, but not circular precisely, but spiral. He is relying in part on the geometry of spirals by--Apollonius?--a good example, to my mind, of the "geometrization of space." The equation of freefall is also demonstrated geometrically in a way that is very elegant. It should also be noted that Simplicio is hardly the fool that he is made out to be--his objections are far more acute than this reader could come up with on his own. The enormous prestige of physics and science is in my opinion one of the greatest obstacles to thinking, and reading Galileo goes a long way towards an appreciation of what mathematical physics is not.
