PDF-(EBOOK)-Just Six Numbers: The Deep Forces That Shape The Universe

How did a single genesis event create billions of galaxies black holes stars and planets How did atoms assemble here on earth and perhaps on other worlds into living beings intricate enough to ponder their origins What fundamental laws govern our universeThis book describes new discoveries and offers remarkable insights into these fundamental questions There are deep connections between stars and atoms between the cosmos and the microworld Just six numbers imprinted in the big bang determine the essential features of our entire physical world Moreover cosmic evolution is astonishingly sensitive to the values of these numbers If any one of them were untuned there could be no stars and no life This realization offers a radically new perspective on our universe our place in it and the nature of physical laws.

The quality of the deep-sky images is outstanding--a tribute to the various photographers as well as the book\'s printer. But it\'s the written word that will make or break a book like this, and Sue\'s writing is superb... [For] an occasional stargazer, a serious observer, or anyone in between, you won\'t go wrong with Deep-Sky Wonders. This is a great introduction to deep-sky stargazing for novice and experienced amateur astronomers alike. --Mercury, publication of the Astronomical Society of the PacificSue French writes the popular column Deep-Sky Wonders for Sky and Telescope magazine and also teaches deep sky observation. She has earned a loyal following among enthusiasts and is welcomed by beginners for her skill at presenting astronomy in an understandable way. After selling 10,000 copies of Deep-Sky Wonders in hardcover, we expect a good response for this paperback edition at an accessible price.Deep-Sky Wonders is a collection of 100 of French\'s best Deep-Sky Wonders columns originally published in Sky and Telescope, which has a monthly readership exceeding 100,000. The book is organized by season and subdivided into months for a total of 100 in-depth tours of the deep sky. Each deep sky tour illuminates little-known seasonal wonders that lie off the beaten path.Features include:Full-color photographs and detailed sketches of each deep sky tour Descriptions of double and variable stars, star clusters, nebulae, galaxies and exotics Historical and scientific background of particular interest A tabular listing of the deep-sky sites Color charts showing the position of each target in the night sky An index to all of the deep-sky objects covered. Deep-Sky Wonders also features a variety of challenging objects that encourage observers to test the limits of their equipment and skills. Suitable for beginner and intermediate small-scope astronomers as well as large-scope viewers and astrophotographers, this book will be greeted enthusiastically by all Sky and Telescope readers. It is also an outstanding introduction to deep-sky viewing for novice observers. Don delivers pint bottles of milk to two streets.
