Problem solving

Gestalt psychology Gestalt psychology or gestaltism (German: Gestalt – "shape or form") is a theory of mind of the Berlin School. The central principle of gestalt psychology is that the mind forms a global whole with self-organizing tendencies. This principle maintains that the human mind considers objects in their entirety before, or in parallel with, perception of their individual parts; suggesting the whole is other than the sum of its parts. In the domain of perception, Gestalt psychologists stipulate that perceptions are the products of complex interactions among various stimuli. Origins[edit] Both von Ehrenfels and Edmund Husserl seem to have been inspired by Mach's work Beiträge zur Analyse der Empfindungen (Contributions to the Analysis of Sensations, 1886), in formulating their very similar concepts of gestalt and figural moment, respectively. These laws took several forms, such as the grouping of similar, or proximate, objects together, within this global process. Gestalt therapy[edit] Invariance

Creative problem-solving From Wikipedia, the free encyclopedia Creative problem-solving (CPS)[1] is the mental process of searching for an original and previously unknown solution to a problem. To qualify, the solution must be novel and reached independently.[1][2] The creative problem-solving process was originally developed by Alex Osborn and Sid Parnes. Creative problem solving (CPS) is a way of using creativity to develop new ideas and solutions to problems. Creative solution types[edit] The process of creative problem-solving usually begins with defining the problem. A creative solution will often have distinct characteristics that include using only existing components, or the problematic factor, as the basis for the solution. If a creative solution has a broad application, such that the usage goes beyond the original intent, it may be referred to as an innovative solution, or an innovation (some innovations may also be considered an invention).

Leet One way to write the word "Wikipedia" in Leet Leet (or "1337"), also known as eleet or leetspeak, is an alternative alphabet for the English language that is used primarily on the Internet. It uses various combinations of ASCII characters to replace Latinate letters. For example, leet spellings of the word leet include 1337 and l33t; eleet may be spelled 31337 or 3l33t. History Leet symbols, especially the number 1337, are Internet memes that have spilled over into popular culture. Orthography One of the hallmarks of leet is its unique approach to orthography, using substitutions of other characters, letters or otherwise, to represent a letter or letters in a word.[4][5] For more casual use of leet, the primary strategy is to use homoglyphs, symbols that closely resemble (to varying degrees) the letters for which they stand. Morphology Text rendered in leet is often characterized by distinctive, recurring forms. The -xor suffix The -age suffix The -ness suffix Words ending in -ed Grammar n00b Pr0n

LEARNER INPUT Abstraction Abstraction is a process by which concepts are derived from the usage and classification of literal ("real" or "concrete") concepts, first principles, or other methods. "An abstraction" is the product of this process—a concept that acts as a super-categorical noun for all subordinate concepts, and connects any related concepts as a group, field, or category.[1] Abstractions may be formed by reducing the information content of a concept or an observable phenomenon, typically to retain only information which is relevant for a particular purpose. For example, abstracting a leather soccer ball to the more general idea of a ball retains only the information on general ball attributes and behavior, eliminating the other characteristics of that particular ball.[1] Origins[edit] Thinking in abstractions is considered[by whom?] Abstraction involves induction of ideas or the synthesis of particular facts into one general theory about something.

Claude Shannon: How a Real Genius Solves Problems It took Claude Shannon about a decade to fully formulate his seminal theory of information. He first flirted with the idea of establishing a common foundation for the many information technologies of his day (like the telephone, the radio, and the television) in graduate school. It wasn’t until 1948, however, that he published A Mathematical Theory of Communication. This wasn’t his only big contribution, though. To the average person, this may not mean much. The word genius is thrown around casually, but there are very few people who actually deserve the moniker like Claude Shannon. One of the subtle causes behind what manifested as such genius, however, was the way he attacked problems. His problems were different from many of the problems we are likely to deal with, but the template and its reasoning can be generalized to some degree, and when it is, it may just help us think sharper, too. All problems have a shape and a form. Build a Core Before Filling the Details All You Need to Know

Who Runs Wikipedia? (Aaron Swartz's Raw Thought) During Wikimania, I gave a short talk proposing some new features for Wikipedia. The audience, which consisted mostly of programmers and other high-level Wikipedians, immediately begun suggesting problems with the idea. “Won’t bad thing X happen?” At the time, I was just happy this quieted them down. It wasn’t because its programmers were so far-sighted that the software solved all the problems. No, the reason Wikipedia works is because of the community, a group of people that took the project as their own and threw themselves into making it succeed. People are constantly trying to vandalize Wikipedia, replacing articles with random text. Why does anyone do such a thing? It’s hard to imagine anyone feeling this way about Britannica. Everybody knows Wikipedia as the site anyone can edit. But what’s less well-known is that it’s also the site that anyone can run. This is so unusual, we don’t even have a word for it. But Wikipedia’s openness isn’t a mistake; it’s the source of its success.

LEARNER INPUT Symmetry Sphere symmetrical group o representing an octahedral rotational symmetry. The yellow region shows the fundamental domain. Symmetry (from Greek συμμετρία symmetria "agreement in dimensions, due proportion, arrangement")[1] has two meanings. Although these two meanings of "symmetry" can sometimes be told apart, they are related, so they are here discussed together.[3] Mathematical symmetry may be observed This article describes these notions of symmetry from four perspectives. The opposite of symmetry is asymmetry. Geometry[edit] A geometric object is typically symmetric only under a subgroup of isometries. Reflectional symmetry[edit] An isosceles triangle with mirror symmetry. A drawing of a butterfly with bilateral symmetry Reflectional symmetry, mirror symmetry, mirror-image symmetry, or bilateral symmetry is symmetry with respect to reflection. If the letter T is reflected along a vertical axis, it appears the same. Point reflection and other involutive isometries[edit] .
