Powers of Ten is a 1977 short documentary 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.The film begins with an aerial image of a man reclining on a blanket; the view is that of one meter across. The viewpoint, accompanied by expository voiceover by Philip Morrison, then slowly zooms out to a view ten meters across (or 101 m in standard form), revealing that the man is picnicking in a park with a female companion. The zoom-out continues (at a rate of one power of ten per 10 seconds), to a view of 100 meters (10² m), then 1 kilometre (10³ m), and so on, increasing the perspective—the picnic is revealed to be taking place near Soldier Field on Chicago‘s lakefront—and continuing to zoom out to a field of view of 1024 meters, or the size of the observable universe. The camera then zooms back in at a rate of a power of ten per 2 seconds to the picnic, and then slows back down to its original rate to views of negative powers of ten—10-1 m (10 centimeters), and so forth, until carbon nucleus is visible inside the man’s hand at a range of 10-16 meter.
