- The Gospel of Thomas (also known as the Coptic Gospel of Thomas) is a non-canonical sayings gospel. The Gospel differs in tone and structure from other New Testament apocrypha and the canonical Gospels. It is not a narrative account of Jesus’ life but consists of logia (sayings) attributed to Jesus, sometimes stand-alone, sometimes embedded in short dialogues or parables; 13 of its 16 parables are also found in the Synoptic Gospels. The text contains a possible allusion to the death of Jesus in logion 65 (Parable of the Wicked Husbandmen), but does not mention his crucifixion, his resurrection, or the Last Judgment; nor does it mention a messianic understanding of Jesus.
- n-body problem (Wikipedia)
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.
