01 Meaning
What does kaleidoscope mean?
Inside a kaleidoscope, two or more mirrors are set at an angle to each other. Loose pieces of colored glass at one end are reflected into a symmetrical pattern that you see from the other end, and rotating the end of the tube changes the pattern.
Wikipedia credits David Brewster with first noticing the effect in 1814, while studying the polarization of light, and records a British patent granted in July 1817. The word also works as a verb: to kaleidoscope is to move in shifting, colorful patterns.
02 Word origin
Where does it come from?
Scottish scientist David Brewster coined the word for the device he invented in 1816 and introduced in 1817. It combines the ancient Greek words kalos, "beautiful", and eidos, "form", with the ending -scope, for an instrument used to look. Wikipedia glosses the result as roughly "observation of beautiful forms".
kaloseidos-scope
"beautiful" + "form" + an instrument for viewing
