In mathematics and science, the lowercase psi is widely employed as a symbol for wave functions in quantum mechanics, for the digamma function in number theory, and for the psi angle in trigonometry. It also appears in psychology, where it is associated with parapsychology and the study of psychic phenomena, as well as in biochemistry to denote the pseudouridine nucleoside.
