Pronunciation

Noun

[edit]

glider (plural gliders)

modern glider-type swing
Glider in Conway's Life
  1. One who glides.
  2. Any heavier-than-air aircraft optimised for unpowered flight; a sailplane.
  3. A pilot of glider aircraft.
  4. Any animal with the ability to glide, such as the marsupial gliding possums of Australia.
  5. Synonym of glide (“cap affixed to base of legs of furniture”)
    • 2007, Frances Gruber Safford, American Furniture in the Metropolitan Museum of Art:
      The left drawer runner is probably replaced. Nail holes on the upper surface of the stretchers suggest the piece once had a bottom shelf. Modern metal gliders have been added under the feet.
  6. A kind of garden swing.
    • 1978, Tom Reamy, Blind Voices, published 2003, page 73:
      Francine sat in the glider on the porch, swinging lightly, her mind a thousand miles away. The chain squeaked a little, almost like a cricket.
    • 2011, Mary Biever, He Uses It For Good!, page 5:
      Then I went into the backyard, which had a flower-covered arbor, a small garden wall, and room behind it for a garden. Swings and gliders adorned the yard.
  7. (cellular automata) In the Game of Life, a particular configuration of five cells that recurs periodically at fixed offsets and appears to "walk" across the grid.
    Hypernym: spaceship
    • 1989 December 22, Norbert Roestel, “CA-LETTER”, in comp.theory.cell-automata‎[1] (Usenet):
      By the way, what happens to a beehive which is under attack by one or two gliders such as pictured:
    • 2006 September 28, Dave Greene, “Small Heisenburp device in Conway's Life”, in comp.theory.cell-automata‎[2] (Usenet):
      I believe it is indeed new -- I've gone back through everything I can find, as far back as the early 90's when Heisenburp devices were first invented, and there don't seem to be any reactions based on a glider suppressing a blinker.
    • 2008, Derek Abbott, Paul C. W. Davies, Arun Kumar Pati, Quantum Aspects Of Life, page 246:
      In Conway's Life interesting effects can be obtained by colliding gliders.
    1. (by extension) Any spaceship in a cellular automaton, especially one which exhibits glide reflection.
      • 1989 June 11, David Hiebeler, comp.theory.cell-automata (Usenet):
        It is a reversible rule, and an interesting one. Shortly after I implemented it, Chris and I were watching it run from a small random configuration of vants, when we noticed a structure consisting of 2 vants propagating away from the others -- it is a glider of sorts, consisting of 2 cooperating vants moving along, erasing each others' trail.
      • 2003 May 13, Frank Buss, “Totalistic Explorer and squirm”, in comp.theory.cell-automata (Usenet):
        I wanted to test some totalistic automaton and the glider with the B024S1 rule, which Ilmari Karonen described.
      • 2007 May 12, Dave Greene, “Wanted: 2D CA, "as complex" but "denser" than Life”, in comp.theory.cell-automata‎[3] (Usenet):
        By contrast, consider a rule like Seeds (B2/S) that has "gliders" and oscillators and so forth, so theoretically it might support universal computation somehow.
  8. A vehicle, of a usually motorised type, without a powertrain.
  9. (entomology) Any of various species of dragonfly that glide on out-held wings while flying, such as the common glider, Tramea loewii, of Australia, New Guinea, Indonesia, and the Pacific.
