Theoretically predicted adatom diffusion mechanism on the fcc[100] surface of some common metals, including Copper, Aluminum, Silver, Gold, Paladium, Platinum, and Nickel. A single atom makes a knight's move across the surface via the illustrated exchange. The primary atoms are colorized for demonstration purposes. All atoms are of the same element. Credit: J.M.

The kaleidoscope was invented in 1816 by Sir David Brewster, a Scottish physicist and Christian minister. The origin of the word kaleidoscope speaks to the splendid images. Kaleidoscope finds its roots in the Greek word kalos meaning beautiful, the Indo-european eidos that means form, and scope that is Greek for to see.
See how all those images come together.
