Postmodern literaturePostmodern literature is a form of literature that is characterized by the use of metafiction, unreliable narration, self-reflexivity, intertextuality, and which often thematizes both historical and political issues. This style of experimental literature emerged strongly in the United States in the 1960s through the writings of authors such as Kurt Vonnegut, Thomas Pynchon, William Gaddis, Philip K. Dick, Kathy Acker, and John Barth.
Benguela CurrentThe Benguela Current bɛŋˈɡɛlə is the broad, northward flowing ocean current that forms the eastern portion of the South Atlantic Ocean gyre. The current extends from roughly Cape Point in the south, to the position of the Angola-Benguela front in the north, at around 16°S. The current is driven by the prevailing south easterly trade winds. Inshore of the Benguela Current proper, the south easterly winds drive coastal upwelling, forming the Benguela Upwelling System.
Gödel metricThe Gödel metric, also known as the Gödel solution or Gödel universe, is an exact solution of the Einstein field equations in which the stress–energy tensor contains two terms, the first representing the matter density of a homogeneous distribution of swirling dust particles (dust solution), and the second associated with a negative cosmological constant (see Lambdavacuum solution). This solution has many unusual properties—in particular, the existence of closed time-like curves that would allow time travel in a universe described by the solution.
