singularity(sing-gyŭ-la -ră-tee) A mathematical point at which space and time are infinitely distorted. Calculations predict that every black hole must contain a singularity: matter falling into a black hole will ultimately be compressed to infinite densities at a single point, and in such conditions our laws of physics, including quantum mechanics, must break down. One black-hole theorem – the principle of cosmic censorship – states that singularities are always concealed by an event horizon so that they cannot communicate their existence to an observer in our Universe. However, if a naked singularity – a singularity without an event horizon – is found, then some of our physical concepts will need reexamination.
A point where a function of real or complex variables is not differentiable or analytic. Also known as singular point of a function.
A characteristic meteorological condition which tends to occur on or near a specific calendar date more frequently than chance would indicate; an example is the January thaw.
A region of space-time where one or more components of the Riemann curvature tensor becomes infinite.

(2) (Singularity) An experimental operating system from Microsoft for the x86 platform written almost entirely in C#, a .NET managed code language. Released in 2007, Singularity is a non-Windows research project.
Like Windows, there is only one address space, but for security and crash protection, it runs each OS or application process in an environment called a "software-isolated process" (SIP). Unlike other OS architectures, SIPs and the interprocess communications between them are analyzed for compliance at compile time. In addition, when a program is installed, it must include a manifest of its actions that comply with certain rules. For more information, visit http://research.microsoft.com/os/singularity.
