Knot

 

in navigation, a unit used to define the speed of a vessel. One knot is equal to 1 nautical mile per hr, 1.852 km per hr, or 0.5144 m per sec. The term “knot” originated in the days of sailing fleets, when a ship’s speed was determined by how quickly a log line played out from a log reel. The log line was divided into segments of 50 feet 8 inches (1/120 of a nautical mile), and the segments were marked by knots in the line. The rate at which the line unreeled was measured for 30 seconds (1/120 of an hour). The number of knots (segments) unreeled in 30 seconds corresponded to the ship’s speed in nautical miles per hour, that is, in knots.


Knot

 

a temporary connection made between two ropes or between a rope and some object. Knots are tied in such a way that they become more secure as tension on the rope increases. The loops of a knot loose their grip when tension on the rope is decreased, which makes it easier to untie the knot. Different types of knots are used for different purposes, for example, to tie together two ropes of the same or different thickness, to fasten ropes to moorings, or to hoist long, smooth objects.

What does it mean when you dream about a knot?

A knot is an obvious symbol of constraints and restrictions on one’s freedom of thought, feelings, or actions, indicating a difficult situation that needs to be untied. Anxieties about getting married (“tying the knot”) are sometimes denoted by this dream symbol. More positively, a knot can symbolize control, and having something “all wrapped up.” (See also Necktie).
