Did you know?

Small wonder that the oldest meaning of microcosm in our dictionary is “little world”: the word comes ultimately from the Greek phrase mikros kosmos, meaning “little universe.” That meaning can be applied to many a wee realm, as in “the microcosm of the atom,” but microcosm was originally used by medieval scholars specifically to refer to humans as miniature embodiments of the natural universe. Microcosm soon expanded to refer to places (such as neighborhoods or other communities) thought to embody at a small scale characteristics of larger places, and later to anything serving as an apt representation of something bigger—as when Arthur C. Clarke, famed author of much fiction and nonfiction set in the cosmos, noted that “a sunken ship is a microcosm of the civilization that launched it.”
