disconnected

In topology and related branches of mathematics, a totally disconnected space is a topological space that is maximally disconnected, in the sense that it has no non-trivial connected subsets. In every topological space, the singletons (and, when it is considered connected, the empty set) are connected; in a totally disconnected space, these are the only connected proper subsets.
An important example of a totally disconnected space is the Cantor set. Another example, playing a key role in algebraic number theory, is the field Qp of p-adic numbers.

    Hi, I recently had a new kitchen fitted and it appears that the old cold water inlet valves (one pipe with 2 blue T valves connectors for old d/w and w/m) have been left in situ without being capped off. I’m very worried that they’ll leak, especially as they don’t have a cap on them. Problem...
