- In physics, the n-body problem is the problem of predicting the individual motions of a group of celestial objects interacting with each other gravitationally. Solving this problem has been motivated by the desire to understand the motions of the Sun, Moon, planets, and visible stars. In the 20th century, understanding the dynamics of globular cluster star systems became an important n-body problem. The n-body problem in general relativity is considerably more difficult to solve due to additional factors like time and space distortions.
- Book of Revelation (Wikipedia)
The Book of Revelation, also erroneously called the Book of Revelations, is the final book of the New Testament (and therefore the final book of the Christian Bible). Written in Koine Greek, its title is derived from the first word of the text: apokalypsis, meaning ‘unveiling’ or ‘revelation’. The Book of Revelation is the only apocalyptic book in the New Testament canon. It occupies a central place in Christian eschatology.
