Film: Symmetry in Physical Law. (Feynman) Film Title: Symmetry in Physical Law. Level: Upper elementary-Adult. Length: 57 minutes. Black and white, with sound. Description: Explains that physical laws are symmetrical: there are things we can do to a physical law, but they leave the law unchanged in its effects. The symmetries of physical phenomena are discussed: translations in space and time, rotations in space, the right- and left-handedness of fundamental interactions and of living things, the consequence of relative motion, and the interconnections of space and time. IRREVERSIBILITY AND FLUCTUATIONS.
