A knot consist of lengths of one or several ropes, coiled through themselves in a way to produce a structural altering the characteristics of the rope. Knots may be used for fastening ropes to other structures, other ropes, or to let a rope slide along another rope.
Knots are instrumental in sailing and climbing, and many other activities.
Well known knots include:
- noose
- slip
- bowline
- sheet bend
- square
- figure eight
- overhand
- single stopper
- double stopper
- reef knot
- clove hitch
- half hitch
- italian hitch
descriptions and tying instructions should be added
In knot theory, a knot is an embedding of a circle in 3-D space, considered up to deformations (isotopies). This is basically equivalent to a conventional knot with the ends of the string tied together to prevent it from becoming undone. In higher dimensions, circles are unknotted anyways, so one considers embeddings of spheres and hyperspheres.
