Editing Singularity (section)

==Science, technology, and mathematics==
===Mathematics===
* [[Mathematical singularity]], a point at which a given mathematical object is not defined or not "well-behaved", for example infinite or not differentiable

====Geometry====
* [[Singular point of a curve]], where the curve is not given by a smooth embedding of a parameter
* [[Singular point of an algebraic variety]], a point where an algebraic variety is not locally flat
* [[Rational singularity]]

===Natural sciences===
* [[Singularity (system theory)]], in dynamical and social systems, a context in which a small change can cause a large effect
* [[Gravitational singularity]], in general relativity, a point in which gravity is so intense that spacetime itself becomes ill-defined
** [[Initial singularity]], a hypothesized singularity of infinite density before quantum fluctuations caused the Big Bang and subsequent inflation that created the Universe
* [[Penrose–Hawking singularity theorems]], in general relativity theory, theorems about how gravitation produces singularities such as in black holes
* [[Prandtl–Glauert singularity]], the point at which a sudden drop in air pressure occurs
* [[Singularity (climate)]], a weather phenomenon associated with a specific calendar date
* [[Van Hove singularity]] in the density of states of a material

===Technology===
* [[Singularity (operating system)]], an experimental operating system developed by Microsoft Research
* [[Mechanical singularity]], a position or configuration of a mechanism or a machine where the subsequent behavior cannot be predicted
* [[Singularity (software)]], a container technology that does not require root permissions to run

===Futurology===
* [[Technological singularity]], a hypothetical point in time when technological growth becomes uncontrollable and irreversible
