Knot Theory
Knot theory is a branch of topology. It deals with the mathematical analysis of knots, their structure and properties, and with the relationships between different knots. In topology, a knot is a figure consisting of a single loop, abstracted from any physical rope or line, with any number of crossing or "knotted" elements. As such, it has no proper ends, and cannot be undone or untied. Various mathematical techniques are used to classify and distinguish knots. For instance, the Alexander polynomial can be used to distinguish the trefoil knot from the figure-eight knot and the unknot (a simple loop).

Famous quotes containing the words knot and/or theory:
“Separation’s fire
can be borne
when there’s a knot of hope,
but Mother,
when my love leaves home
and stays in the same village,
it’s far worse than death.”
—Hla Stavhana (c. 50 A.D.)
“A theory if you hold it hard enough
And long enough gets rated as a creed....”
