  Science tidbit

Kaleidoscope image.
Kaleidoscope Optics

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.
