Origin Story
A kaleidoscope endlessly shifts its colorful patterns with every turn. Its English name elegantly holds three Greek words: kalos, meaning "beautiful"; eidos, meaning "shape" or "form"; and skopein, meaning "to look." Together they mean "an instrument for viewing beautiful shapes." In 1817, the Scottish scientist David Brewster invented the device using mirrors and bits of colored glass, then chose a Greek name that fit its principle perfectly. With three concepts — beauty, shape, and sight — packed into a single word, the name is as intricate as the kaleidoscope's own mystery.
The element -scope ("an instrument for viewing") also appears in telescope and microscope. They all belong to one family, descended from the Greek skopein ("to look").
