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.
Example:
1.
Viva la revolution! (The revolution lives!)
2. It takes 365.24 days
for the Earth to make a full revolution around the sun (according to the
atomic clock), which is why our leap year adds another day every four years-- to make it reach 365.25. Because these numbers don't match exactly, our years are actually inaccurate, moreso as time goes on.
