	'''Mu''' (uppercase '''Μ''', lowercase '''μ'''; [[Ancient Greek]] μῦ mŷː), [[Modern Greek]] μι or μυ mi\|) is the 12th letter of the [[Greek alphabet]]. In the system of [[Greek numerals]] it has a value of 40. Mu was derived from the [[Egyptian hieroglyph]]ic symbol for water (𓈖) which had been simplified by the [[Phoenicia]]ns and named after their word for water, to become [[Mem\|𐤌]]. Letters that arose from mu include the Roman [[M]] and the Cyrillic letter [[Em (Cyrillic)\|М]].

	Μμ Mu		'''Mu''' (uppercase '''Μ''', lowercase '''μ'''; [[Ancient Greek]] {{polytonic\|μῦ}} {{IPA-el\|mŷː\|}}), [[Modern Greek]] μι or μυ {{IPA-el\|mi\|}}) is the 12th letter of the [[Greek alphabet]]. In the system of [[Greek numerals]] it has a value of 40. Mu was derived from the [[Egyptian hieroglyph]]ic symbol for water (𓈖) which had been simplified by the [[Phoenicia]]ns and named after their word for water, to become [[Mem\|𐤌]]. Letters that arose from mu include the Roman [[M]] and the Cyrillic letter [[Em (Cyrillic)\|М]].

			==Names==
			===Ancient Greek===
			In [[Ancient Greek]], the name of the letter is written {{polytonic\|μῦ}} and pronounced {{IPA-el\|mŷː\|}}.

			===Modern Greek===
			In [[Modern Greek]], the name of the letter is spelled μι and pronounced {{IPA-el\|mi\|}}. In monotonic orthography, the ancient version is written with an [[acute accent]] instead of a [[circumflex]]: μύ.

			==Symbol==
			The lower-case letter mu (μ) is used as a special symbol in many [[academic field]]s. The upper case mu is not used, since it is normally identical to Latin [[M]].

			===Mathematics===
			In [[mathematics]]:
			*the µ-roots of a [[complex number]] ''z = a + bi''
			*the [[Möbius function]] in [[number theory]]
			*the [[integrating factor]] in [[ordinary differential equations]]
			*the population [[mean]] or [[expected value]] in [[probability]] and [[statistics]]
			*a [[measure (mathematics)\|measure]] in [[measure theory]]
			*[[Mu operator\|minimalization]] in [[Computability theory (computer science)\|computability theory]] and [[Recursion theory]]
			*the learning rate as used in [[artificial neural networks]]

			===Measurement===
			In measurement:
			*the [[SI prefix]] ''[[micro-]]'', which represents one millionth, or 10<sup>−6</sup>.
			*the micron, an old unit which corresponds to the [[micrometre]] (which is now denoted "µm")

			===Physics and engineering===
			In [[classical physics]] and [[engineering]]:
			*the [[friction#Coefficient of friction\|coefficient of friction]] (also used in aviation as braking coefficient)
			*[[reduced mass]] in the [[two-body problem]]
			*[[linear density]] or mass per unit length in strings and other one-dimensional objects.
			*[[permeability (electromagnetism)\|permeability]] in [[electromagnetism]]
			*the [[magnetic dipole moment]] of a current-carrying coil
			*[[Viscosity#Viscosity .28dynamic viscosity.29: .CE.BC\|dynamic viscosity]] in [[fluid mechanics]]
			*the [[Amplifier\|amplification]] factor of a [[triode]] [[vacuum tube]]
			*the [[electrical mobility]] of a charged particle
			*the [[airspeed]] relative to rotor tip speed, in [[rotorcraft]]

			In [[particle physics]]:
			*the [[elementary particle]]s called the [[muon]] and antimuon

			In [[thermodynamics]]:
			*the [[chemical potential]] of a system or component of a system.

			===Chemistry===
			In [[chemistry]]:
			*the prefix given in [[IUPAC]] nomenclature for a [[bridging ligand]].

			===Pharmacology===
			In [[pharmacology]]:
			*an important [[opiate receptor]]

			===Orbital mechanics===
			In [[orbital mechanics]]:
			*[[Standard gravitational parameter]] of a [[celestial body]], the product of the [[gravitational constant]] ''G'' and the [[mass]] ''M''.
			*planetary discriminant, represents an experimental measure of the actual degree of [[Clearing the neighbourhood\|cleanliness]] of the orbital zone, a [[wiktionary:criterion\|criterion]] for [[IAU definition of planet\|defining]] a [[planet]]. µ is calculated by dividing the mass of the candidate body by the total mass of the other objects that share its orbital zone.

			===Music===
			*[[Mu major chord]]

			===Software===
			In [[application software\|application]] names:
			*[[μTorrent]], a [[BitTorrent]] client

			===Cameras===
			The [[Olympus Corporation]] manufactures a series of digital cameras called Olympus µ[mju:] or Olympus Stylus.<sup>[1]</sup>

			===Linguistics===
			In [[phonology]], it often stands for [[mora (linguistics)\|mora]].

			==Computing==

			In Unicode, the upper and lower case mu are encoded at {{u+\|039C}} and {{U+\|03BC}} respectively. In [[ISO 8859-7]] they are encoded at CC<sub>[[hexadecimal\|HEX]]</sub> and EC<sub>HEX</sub>. In HTML code, the μ character is represented by "&#956;", "&#x3BC;" and the entity "&mu;".

			The [[Micro-\|'''micro sign''']] or [[micron]] is considered a distinct [[Character (word)\|character]] from the Greek alphabet letter by Unicode for historical reasons (although it is a [[homoglyph]]) and is found at U+00B5 as well as position B5<sub>HEX</sub> in [[ISO 8859]]-[[ISO-8859-1\|1]], [[ISO-8859-3\|3]], [[ISO-8859-8\|8]], [[ISO-8859-9\|9]], [[ISO-8859-13\|13]] and [[ISO-8859-15\|15]], and thus in the corresponding Windows code pages [[Windows-1252]] etc. In HTML code, the µ symbol is represented by "&#181;", "&#xB5;" and the [[HTML entity\|entity]] "&micro;". When Alt-0181 or the [[code page 437\|DOS legacy]] Alt+230 is typed into an editable field using the [[numeric keypad]] in [[Microsoft Windows]], the µ symbol appears. Also pressing AltGr + M results in a µ on some keyboard layouts.

			Because µ is the abbreviation for the [[metric system]] prefix [[micro-]], the symbol is used in many word plays about the field of micro-computing. For example, the symbol is used in the name and logo of the popular [[bittorrent client]], [[µTorrent]]. Also, the microcontrollers are commonly represented in schematics as µC. It is sometimes simply substituted with a '''u''', the most similar-looking [[ASCII]] glyph, eg. ''uTorrent''.
