About this book

Astrolabe: The Universe in the Palm of Your Hand! Astronomy through the eyes of the ancient observers: You will be astonished at the detail and subtle complexity that Hipparchus and Ptolemy can still teach us about the solar system. This knowledge is preserved for us in the book rightly known to the Arabs of antiquity as “The Greatest” (al-majisti), from which we get the modern title, “Almagest.” Learn its secrets here! Use inexpensive, modern software to draw an astrolabe: Learn to use the geometric construction methods of Ptolemy. Once you’ve mastered the 2000 year–old principles behind the stereographic projection, and made a working astrolabe yourself, you will truly have a conceptual grasp of the workings of the universe. With your working astrolabe, and an understanding of its power and use, you will literally have the universe in the palm of your hand! Acid etch your astrolabe for posterity: This book teaches how to use your drawings to manufacture a working metal astrolabe, safely etched in an acid bath in your back yard. Wooden and paper astrolabes are discussed too. Learn to use your masterwork: Follow examples that guide you through the myriad of problems that may be solved with your astrolabe. Tell the time from the sun or the stars and impress your friends!
