"E psilon" ("simple e") was coined to distinguish the letter from αι, which by the medieval period was pronounced the same way.

Symbol


The upper-case Epsilon is not a very often used symbol outside of the Greek language because of its similarity to the Roman letter E.

The lower-case letter ε is used as the symbol for:

  • In mathematics (particularly calculus), a small positive quantity, usually denoted ε; see limit.
    • By analogy with this, the late mathematician Paul Erdős also used the term "epsilons" to refer to children (Hoffman 1998, p. 4).
  • In set theory, the limit ordinal of the sequence \omega,\omega^{\omega},\omega^{\omega^{\omega}},\dots.
  • In computing, the precision of a numeric data type.
  • In computer science, the empty string, though different writers use a variety of other symbols for the empty string as well, including the lower case Greek letter lambda.
  • In mathematics, the Levi-Civita symbol.
  • In mathematics, set membership (often written ∈ instead of ε).
  • In physics, the permittivity of a medium.
  • In physics/electronics, the EMF of a circuit
  • In automata theory, a transition that involves no shifting of an input symbol.
  • In astronomy, the fifth brightest (usually) star in a constellation. See Bayer designation.
  • In phonetics, the open or lax mid-front vowel, as in the English word "pet" (/pεt/)
