Mu
Zen's negating answer
Mu is the twelfth letter of the Greek alphabet (Μ, μ), used in English primarily in scientific and technical contexts.
In physics, μ represents the coefficient of friction or magnetic permeability.
In statistics, μ denotes the population mean.
In Zen Buddhism, mu is a response to unanswerable questions—neither yes nor no, but a rejection of the question's premise: The master answered only "mu."
