A figure used in many Asian cultures to symbolize the unity of the two "opposite" female and male elements, the "yin" and "yang." The solid and hollow parts composing the symbol are similar and combine to make a circle. Each part consists of two equal oppositely oriented semicircles of radius 1/2 joined at their edges, plus a semicircle of radius 1 joining the other edges.
