Twelfth letter of the Greek alphabet
Mu (;[1] [2] uppercase Μ , lowercase μ ; Ancient Greek μῦ [mŷː] , Greek : μι or μυ—both [mi] ) is the twelfth letter of the Greek alphabet , representing the voiced bilabial nasal IPA: [m] . In the system of Greek numerals it has a value of 40.[3] Mu was derived from the Egyptian hieroglyphic symbol for water, which had been simplified by the Phoenicians and named after their word for water, to become 𐤌 img (mem). Letters that derive from mu include the Roman M and the Cyrillic М , though the lowercase resembles a small Latin U (u ).
Greek letter mu
Names
[ edit ]
Ancient Greek
[ edit ]
In Greek, the name of the letter was written μῦ and pronounced [mŷː] .
Modern Greek
[ edit ]
In Modern Greek , the letter is spelled μι and pronounced [mi] . In polytonic orthography, it is written with an acute accent : μί .[4] [5]
Use as symbol
[ edit ]
The lowercase letter mu (μ) is used as a special symbol in many academic fields . Uppercase mu is not used, because it appears identical to Latin M .
Prefix for units of measurement
[ edit ]
"μ" is used as a unit prefix denoting a factor of 10−6 (one millionth ), in this context, the symbol's name is "micro ".
Mathematics
[ edit ]
"μ" is conventionally used to denote certain things; however, any Greek letter or other symbol may be used freely as a variable name.
Physics and engineering
[ edit ]
In classical physics and engineering :
In particle physics :
In thermodynamics :
Computer science
[ edit ]
In evolutionary algorithms :
μ, population size from which in each generation λ offspring will generate (the terms μ and λ originate from evolution strategy notation)
In type theory :
Used to introduce a recursive data type . For example,
list
(
τ
)
=
μ
α
.1
+
τ
α
{\displaystyle {\text{list}}(\tau )=\mu {}\alpha {}.1+\tau {}\alpha }
is the type of lists with elements of type
τ
{\displaystyle \tau }
(a type variable ): a sum of unit , representing nil , with a pair of a
τ
{\displaystyle \tau }
and another
list
(
τ
)
{\displaystyle {\text{list}}(\tau )}
(represented by
α
{\displaystyle \alpha }
). In this notation,
μ
{\displaystyle \mu }
is a binding form, where the variable (
α
{\displaystyle \alpha }
) introduced by
μ
{\displaystyle \mu }
is bound within the following term (
1
+
τ
α
{\displaystyle 1+\tau {}\alpha }
) to the term itself. Via substitution and arithmetic, the type expands to
1
+
τ
+
τ
2
+
τ
3
+
⋯
{\displaystyle 1+\tau +\tau ^{2}+\tau ^{3}+\cdots }
, an infinite sum of ever-increasing products of
τ
{\displaystyle \tau }
(that is, a
τ
list
{\displaystyle \tau {}{\text{ list}}}
is any
k
{\displaystyle k}
-tuple of values of type
τ
{\displaystyle \tau }
for any
k
≥
0
{\displaystyle k\geq 0}
). Another way to express the same type is
list
(
τ
)
=
1
+
τ
list
(
τ
)
{\displaystyle {\text{list}}(\tau )=1+\tau {}{\text{list}}(\tau )}
.

Mu chord
Electronic musician Mike Paradinas runs the label Planet Mu which utilizes the letter as its logo, and releases music under the pseudonym μ-Ziq, pronounced "music"
Used as the name of the school idol group μ's, pronounced "muse", consisting of nine singing idols in the anime Love Live! School Idol Project
Official fandom name of Kpop group f(x ) , appearing as either MeU or 'μ'
Hip-hop artist Muonboy has taken inspiration from the particle for his stage name and his first EP named Mu uses the letter as its title.
Cameras
[ edit ]
The Olympus Corporation manufactures a series of digital cameras called Olympus μ [mju:] [9] (known as Olympus Stylus in North America).
Linguistics

In syntax :
μP (mu phrase) can be used as the name for a functional projection.[10]
