Powers of Ten is a 1977 short ocumentary film written and directed by Charles Eames and his wife, Ray. The film depicts the relative scale of the Universe in factors of ten (see also logarithmic scale and order of magnitude). The film is a modern 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. (Boeke's original concept and visual treatment is all too often uncredited or insufficiently credited in contemporary accounts.)
