The Powers of Ten films are two short American documentary films written and directed by Charles and Ray Eames. Both works depict the relative scale of the Universe according to an order of magnitude (or logarithmic scale) based on a factor of ten, first expanding out from the Earth until the entire universe is surveyed, then reducing inward until a single atom and its quarks are observed.
