  2. Standard wire gauge - Wikipedia

    en.wikipedia.org/wiki/Standard_wire_gauge

    The British Standard Wire Gauge, often referred to as the Standard Wire Gauge or simply SWG, is a unit used to denote wire gauge (size) as defined by BS 3737:1964, a standard that has since been withdrawn. It is also known as the Imperial Wire Gauge or British Standard Gauge. Although its use has significantly declined, SWG sizes are still used ...

  3. Aleph number - Wikipedia

    en.wikipedia.org/wiki/Aleph_number

    The aleph numbers differ from the infinity commonly found in algebra and calculus, in that the alephs measure the sizes of sets, while infinity is commonly defined either as an extreme limit of the real number line (applied to a function or sequence that "diverges to infinity" or "increases without bound"), or as an extreme point of the ...

  4. Star Wars Galaxies - Wikipedia

    en.wikipedia.org/wiki/Star_Wars_Galaxies

    In 2011, after SOE announced the intention of shutting down Star Wars Galaxies, Project SWG was founded to emulate the NGE version of Star Wars Galaxies. [67] Project SWG has not been as objectively successful as SWGEmu and has undergone multiple refactors of their code since conception.

  5. HP-16C - Wikipedia

    en.wikipedia.org/wiki/HP-16C

    HP has never made another calculator specifically for programmers, [2] but has incorporated many of the HP-16C's functions in later scientific and graphing calculators, for example the HP-42S (1988) and its successors. Like many other vintage HP calculators, the HP-16C is now highly sought-after by collectors. [14]

  6. Galileo's paradox - Wikipedia

    en.wikipedia.org/wiki/Galileo's_paradox

    The relevant section of Two New Sciences is excerpted below: [2]. Simplicio: Here a difficulty presents itself which appears to me insoluble.Since it is clear that we may have one line greater than another, each containing an infinite number of points, we are forced to admit that, within one and the same class, we may have something greater than infinity, because the infinity of points in the ...

  7. Surreal number - Wikipedia

    en.wikipedia.org/wiki/Surreal_number

    A visualization of the surreal number tree. In mathematics, the surreal number system is a totally ordered proper class containing not only the real numbers but also infinite and infinitesimal numbers, respectively larger or smaller in absolute value than any positive real number.

  8. Penrose diagram - Wikipedia

    en.wikipedia.org/wiki/Penrose_diagram

    Penrose diagram of an infinite Minkowski universe, horizontal axis u, vertical axis v. In theoretical physics, a Penrose diagram (named after mathematical physicist Roger Penrose) is a two-dimensional diagram capturing the causal relations between different points in spacetime through a conformal treatment of infinity.

  9. Ramanujan summation - Wikipedia

    en.wikipedia.org/wiki/Ramanujan_summation

    Ramanujan summation is a technique invented by the mathematician Srinivasa Ramanujan for assigning a value to divergent infinite series.Although the Ramanujan summation of a divergent series is not a sum in the traditional sense, it has properties that make it mathematically useful in the study of divergent infinite series, for which conventional summation is undefined.
