epsilon
Calculus's tiny quantity
Epsilon is the fifth letter of the Greek alphabet (Ε, ε).
In mathematics and science, epsilon typically represents a very small quantity, especially an arbitrarily small positive number approaching zero: For any epsilon greater than zero, there exists a delta...
The phrase epsilon away means infinitesimally close.
In casual use among technical people, epsilon can mean any negligibly small amount: The difference is epsilon. (Capitalized Epsilon may refer to specific stars or organizations.)
