revolution

1. Most commonly referred to in the form of an uprising. Usually by the people who are doing the revolt, the high powers consider it a rebellion. 2. Also a full orbit around a planet (for satellites/moons) or star (for planets). The origin is interesting: Copernicus published a book in 1543 (apparently it's title is contraversial) Called something to the effect of: "On the Revolution of Heavenly Spheres". The Heavenly spheres is the part in question: some say it's Heavenly Orbs, celestial spheres, Heavenly bodies... but I went with the most common theory. This book caused such an uprising, that the word revolution gained it's new and now common meeting.
