Glide Reflection - Glide Reflection in Cellular Automata

Glide Reflection in Cellular Automata

Glide reflection is common in Conway's Game of Life. The four most common spaceships: the glider, LWSS, MWSS and HWSS all move using glide reflection. Every two iterations these spaceships appear to have been glide reflected to their new positions. Here is the evolution of the lightweight spaceship:

This then carries on glide reflecting in a similar manner.

Famous quotes containing the words glide and/or reflection:

    “All things change, nothing is extinguished.... There is nothing in the whole world which is permanent. Everything flows onward; all things are brought into being with a changing nature; the ages themselves glide by in constant movement.”
    —Ovid (Publius Ovidius Naso)

    “Public morning diversions were the last dissipating habit she obtained; but when that was accomplished, her time was squandered away, the power of reflection was lost, [and] her ideas were all centered in dress, drums, routs, operas, masquerades, and every kind of public diversion. Visionary schemes of pleasure were continually present to her imagination, and her brain was whirled about by such a dizziness that she might properly be said to labor under the distemper called the vertigo.”
    —Sarah Fielding (1710–1768)
