A human knot is a common icebreaker game or team building activity for new people to learn to work together in physical proximity.. The knot is a disentanglement puzzle in which a group of people in a circle each hold hands with two people who are not next to them, and the goal is to disentangle the limbs to get the group into a circle, without letting go of grasped hands.
The cutting of the Gordian Knot is an Ancient Greek legend associated with Alexander the Great in Gordium in Phrygia, regarding a complex knot that tied an oxcart. Reputedly, whoever could untie it would be destined to rule all of Asia. In 333 BC Alexander was challenged to untie the knot.
The knot sum of oriented knots is commutative and associative. A knot is prime if it is non-trivial and cannot be written as the knot sum of two non-trivial knots. A knot that can be written as such a sum is composite. There is a prime decomposition for knots, analogous to prime and composite numbers (Schubert 1949). For oriented knots, this ...
Some possible scenarios emerging during a human knot game by CMG Lee. 1. A solvable unknot. 2. More than one ring. 3. An unsolvable trefoil knot. 4. An unsolvable figure-eight knot. Source: Own work: Author: Cmglee
Knot theorists’ holy grail problem was an algorithm to identify if some tangled mess is truly knotted, or if it can be disentangled to nothing. The cool news is that this has been accomplished!
Disentanglement puzzles (also called entanglement puzzles, tanglement puzzles, tavern puzzles or topological puzzles) [1] are a type or group of mechanical puzzle that involves disentangling one piece or set of pieces from another piece or set of pieces.
For policymakers, denying addicts the best scientifically proven treatment carries no political cost. But there’s a human cost to maintaining a status quo in which perpetual relapse is considered a natural part of a heroin addict’s journey to recovery. Relapse for a heroin addict is no mere setback. It can be deadly.
After realizing that they were bound, they would struggle, tightening the knot. This explanation is plausible given that most cases have been found during winter and in confined spaces. [ 5 ] Emma Burns, curator of natural science at the Otago Museum, said regarding her museum's specimen, "Ship rats [black rats], according to some theories, are ...
