Nu (uppercase/lowercase Ν ν) is a letter of the Greek alphabet used to represent the "n" sound in Ancient and Modern Greek. In the system of Greek numerals, it has a value of 50. Letters that came from it include the Roman N and Cyrillic Н.
In statistics, the lowercase can be used to represent degrees of freedom. In physics, the same letter can also used to represent kinematic viscosity and the frequency of a wave.
