Human Knot
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. Instead, group members should step over or under arms to try to untangle the knot. Not all human knots are solvable (see unknotting problem) and can remain knots or may end up as two or more circles. An easy way to ensure that the game will end up with a single circle with no nodes is to start from a circle of people holding each other hand, looking all towards the center of the circle, and ask some of them to cross his/her arms and swap his left hand with his right hand grasping again the same neighbors. When the game is successfully completed a certain number of people will appear to be outside of the circle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Icebreaker (facilitation)
An icebreaker is a facilitation exercise intended to help members of a group begin the process of forming themselves into a team. Icebreakers are commonly presented as a game to "warm up" the group by helping the members to get to know each other. They often focus on sharing personal information such as names, hobbies, etc. Ice-breakers are also used at social gatherings such as parties in order to introduce guests to one another in situations where they may not know one another. Purpose An icebreaker should be related to the subject or the purpose of the meeting. For example, if a collaborative learning environment is needed for a training project, then an icebreaker exercise that promotes collaboration could be chosen. If the subject of the meeting is literature, then the subject of the meeting could be introduced through an exercise that revolves around a participant's favourite books. Icebreakers should be relaxing and non-threatening. For example, icebreakers in a profes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disentanglement Puzzle
Disentanglement puzzles (also called entanglement puzzles, tanglement puzzles, tavern puzzles or topological puzzles) are a type or group of mechanical puzzle that involves disentangling one piece or set of pieces from another piece or set of pieces. Several subtypes are included under this category, the names of which are sometimes used synonymously for the group: wire puzzles; nail puzzles; ring-and-string puzzles; ''et al''. Although the initial object is disentanglement, the reverse problem of reassembling the puzzle can be as hard as—or even harder than—disentanglement. There are several different kinds of disentanglement puzzles, though a single puzzle may incorporate several of these features. Wire-and-string puzzles upright=1.2, A complex ''Baguenaudier'' puzzle. The goal is to free the string. Wire-and-string puzzles usually consist of: * one piece of string, ribbon or similar, which may form a closed loop or which may have other pieces like balls fixed t ...

Knot
A knot is an intentional complication in cordage which may be practical or decorative, or both. Practical knots are classified by function, including hitches, bends, loop knots, and splices: a ''hitch'' fastens a rope to another object; a ''bend'' fastens two ends of a rope to each another; a ''loop knot'' is any knot creating a loop; and ''splice'' denotes any multi-strand knot, including bends and loops. A knot may also refer, in the strictest sense, to a stopper or knob at the end of a rope to keep that end from slipping through a grommet or eye. Knots have excited interest since ancient times for their practical uses, as well as their topological intricacy, studied in the area of mathematics known as knot theory. History Knots and knotting have been used and studied throughout history. For example, Chinese knotting is a decorative handicraft art that began as a form of Chinese folk art in the Tang and Song Dynasty (960–1279 AD) in China, later popularized in t ...

Unknotting Problem
In mathematics, the unknotting problem is the problem of algorithmically recognizing the unknot, given some representation of a knot, e.g., a knot diagram. There are several types of unknotting algorithms. A major unresolved challenge is to determine if the problem admits a polynomial time algorithm; that is, whether the problem lies in the complexity class P. Computational complexity First steps toward determining the computational complexity were undertaken in proving that the problem is in larger complexity classes, which contain the class P. By using normal surfaces to describe the Seifert surfaces of a given knot, showed that the unknotting problem is in the complexity class NP. claimed the weaker result that unknotting is in AM ∩ co-AM; however, later they retracted this claim. In 2011, Greg Kuperberg proved that (assuming the generalized Riemann hypothesis) the unknotting problem is in co-NP, and in 2016, Marc Lackenby provided an unconditional proof ...

Team Building
Team building is a collective term for various types of activities used to enhance social relations and define roles within teams, often involving collaborative tasks. It is distinct from team training, which is designed by a combine of business managers, learning and development/OD (Internal or external) and an HR Business Partner (if the role exists) to improve the efficiency, rather than interpersonal relations. Many team-building exercises aim to expose and address interpersonal problems within the group. Over time, these activities are intended to improve performance in a team-based environment. Team building is one of the foundations of organizational development that can be applied to groups such as sports teams, school classes, military units or flight crews. The formal definition of team-building includes: * aligning around goals * building effective working relationships * reducing team members' role ambiguity * finding solutions to team problems Team building is one o ...

Communication
Communication (from la, communicare, meaning "to share" or "to be in relation with") is usually defined as the transmission of information. The term may also refer to the message communicated through such transmissions or the field of inquiry studying them. There are many disagreements about its precise definition. John Peters argues that the difficulty of defining communication emerges from the fact that communication is both a Universality (philosophy), universal phenomenon and a Communication studies, specific discipline of institutional academic study. One definitional strategy involves limiting what can be included in the category of communication (for example, requiring a "conscious intent" to persuade). By this logic, one possible definition of communication is the act of developing Semantics, meaning among Subject (philosophy), entities or Organization, groups through the use of sufficiently mutually understood signs, symbols, and Semiosis, semiotic conventions.
