Powers of Ten is a 1977 American documentary short film written and directed by Ray Eames and her husband, Charles Eames. The film depicts the relative scale of the Universe in factors of ten (see also logarithmic scale and order of magnitude). The film is an adaptation of the 1957 book Cosmic View by Kees Boeke, and more recently is the basis of a new book version. Both adaptations, film and book, follow the form of the Boeke original, adding color and photography to the black and white drawings employed by Boeke in his seminal work.
In 1998, "Powers of Ten" was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
