A point where all parallel lines meet.

A point where a measured variable reaches unmeasurable or infinite value.

The value or range of values of a function for which a derivative does not exist.

The technological singularity.

The notion of the Singularity is predicated on Moore's Law, the 1965 observation by the Intel co-founder Gordon Moore, that the number of transistors that can be etched onto a sliver of silicon doubles at roughly two year intervals.
