mu

Friction coefficient symbol

Mu is the twelfth letter of the Greek alphabet (Μ, μ), used in English primarily as a scientific symbol.

In physics, μ represents the coefficient of friction or magnetic permeability.

In statistics, μ denotes a population mean.

The prefix micro- is abbreviated μ, as in μg for microgram.

In Zen Buddhism, mu is a response to koans indicating that a question itself is flawed—neither yes nor no applies.

The master answered only "mu."
