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:

    “We perceive no charms that are not sharpened, puffed out, and inflated by artifice. Those which glide along naturally and simply easily escape a sight so gross as ours.”
    —Michel de Montaigne (1533–1592)

    “With respect to a true culture and manhood, we are essentially provincial still, not metropolitan,—mere Jonathans. We are provincial, because we do not find at home our standards; because we do not worship truth, but the reflection of truth; because we are warped and narrowed by an exclusive devotion to trade and commerce and manufacturers and agriculture and the like, which are but means, and not the end.”
    —Henry David Thoreau (1817–1862)
