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:
“When my lover came to bed,
the knot came untied
all by itself.
My dress,
held up by the strings of a loosened belt,
barely stayed on my hips.
Friend,
that’s as much as I know now.
When he touched my body,
I couldn’t at all remember
who he was,
who I was,
or how It was.”
—Amaru (c. seventh century A.D.)
“Osteopath—One who argues that all human ills are caused by the pressure of hard bone upon soft tissue. The proof of his theory is to be found in the heads of those who believe it.”
—H.L. (Henry Lewis)
