  2. Longitude of the ascending node - Wikipedia

    en.wikipedia.org/wiki/Longitude_of_the_ascending...

    Denoted with the symbol Ω, it is the angle from a specified reference direction, called the origin of longitude, to the direction of the ascending node (☊), as measured in a specified reference plane. [1] The ascending node is the point where the orbit of the object passes through the plane of reference, as seen in the adjacent image.

  3. Lunar node - Wikipedia

    en.wikipedia.org/wiki/Lunar_node

    The ascending node is referred to as the dragon's head with the astronomical or astrological symbol of ☊ and the descending node is known as the dragon's tail with the symbol ☋. In Hindu astronomy , the nodes are considered with the seven planets to form the nine Navagrahas ; the ascending node ☊ is called Rahu and the descending node ...

  4. Sorting - Wikipedia

    en.wikipedia.org/wiki/Sorting

    A standard order is often called ascending (corresponding to the fact that the standard order of numbers is ascending, i.e. A to Z, 0 to 9), the reverse order descending (Z to A, 9 to 0). For dates and times, ascending means that earlier values precede later ones e.g. 1/1/2000 will sort ahead of 1/1/2001.

  5. Kaprekar's routine - Wikipedia

    en.wikipedia.org/wiki/Kaprekar's_routine

    In number theory, Kaprekar's routine is an iterative algorithm named after its inventor, Indian mathematician D. R. Kaprekar. [1] [2] Each iteration starts with a number, sorts the digits into descending and ascending order, and calculates the difference between the two new numbers.

  6. Ascending chain condition - Wikipedia

    en.wikipedia.org/wiki/Ascending_chain_condition

    Assuming the axiom of dependent choice, the descending chain condition on (possibly infinite) poset P is equivalent to P being well-founded: every nonempty subset of P has a minimal element (also called the minimal condition or minimum condition).

  7. Melodic motion - Wikipedia

    en.wikipedia.org/wiki/Melodic_motion

    Melodic motion: ascending vs. descending X conjunct vs. disjunct. Melodic motion is the quality of movement of a melody, including nearness or farness of successive pitches or notes in a melody. This may be described as conjunct or disjunct, stepwise, skipwise or no movement, respectively. See also contrapuntal motion. In a conjunct melodic ...

  8. Right ascension - Wikipedia

    Right ascension and declination as seen on the inside of the celestial sphere.The primary direction of the system is the March equinox, the ascending node of the ecliptic (red) on the celestial equator (blue).

  9. Genealogical numbering systems - Wikipedia

    en.wikipedia.org/wiki/Genealogical_numbering_systems

    The most significant difference between the NGSQ and the Register Systems is in the method of numbering for children who are not carried forward into future generations: The NGSQ System assigns a number to every child, whether or not that child is known to have progeny, and the Register System does not. Other differences between the two systems ...
