  2. Writhe - Wikipedia

    en.wikipedia.org/wiki/Writhe

    In knot theory, the writhe is a property of an oriented link diagram. The writhe is the total number of positive crossings minus the total number of negative crossings. A direction is assigned to the link at a point in each component and this direction is followed all the way around each component. For each crossing one comes across while traveling in this direction, if the strand un

  3. Linking number - Wikipedia

    en.wikipedia.org/wiki/Linking_number

    However, this added condition does not change the definition of linking number (it does not matter if the curves are required to always be immersions or not), which is an example of an h-principle (homotopy-principle), meaning that geometry reduces to topology.

  4. List of kennings - Wikipedia

    en.wikipedia.org/wiki/List_of_kennings

    A kenning (Old English kenning [cʰɛnːiŋɡ], Modern Icelandic [cʰɛnːiŋk]) is a circumlocution, an ambiguous or roundabout figure of speech, used instead of an ordinary noun in Old Norse, Old English, and later Icelandic poetry.

  5. DNA supercoil - Wikipedia

    en.wikipedia.org/wiki/DNA_supercoil

    The above example illustrates that twist and writhe are interconvertible. Supercoiling can be represented mathematically by the sum of twist and writhe. The twist is the number of helical turns in the DNA and the writhe is the number of times the double helix crosses over on itself (these are the supercoils).

    [81] [16] An example of a form of qualitative cartography is a Chorochromatic map of nominal data, such as land cover or dominant language group in an area. [82] Another example is a deep map, or maps that combine geography and storytelling to produce a product with greater information than a two-dimensional image of places, names, and topography.

  8. List of musical symbols - Wikipedia

    en.wikipedia.org/wiki/List_of_musical_symbols

    Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...

  9. Witan - Wikipedia

    en.wikipedia.org/wiki/Witan

    While many modern historians avoid the terms witan and witenagemot, few would go as far as Geoffrey Hindley, who described witenagemot as an "essentially Victorian" coinage. [33] The Blackwell Encyclopaedia of Anglo-Saxon England prefers "king's council" but adds that it was known in Old English as the witan. [34]
