Mathematical beauty Mathematical beauty describes the notion that some mathematicians may derive aesthetic pleasure from their work, and from mathematics in general. They express this pleasure by describing mathematics (or, at least, some aspect of mathematics) as beautiful. Sometimes mathematicians describe mathematics as an art form or, at a minimum, as a creative activity. Comparisons are often made with music and poetry. Bertrand Russell expressed his sense of mathematical beauty in these words: Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. Beauty in method[edit] Mathematicians describe an especially pleasing method of proof as elegant. Beauty in results[edit] The opposite of deep is trivial. Perhaps ironically, Monastyrsky writes:

Bibliobs - Actualité littéraire par L'Obs Contrasting and categorization of emotions The contrasting and categorisation of emotions describes how emotions are thought to relate to each other. Various recent proposals of such groupings are described in the following sections. Contrasting basic emotions[edit] The following table,[1] based on a wide review of current theories, identifies and contrasts the fundamental emotions according to a set of definite criteria. The three key criteria used include mental experiences that: have a strongly motivating subjective quality like pleasure or pain;are in response to some event or object that is either real or imagined;motivate particular kinds of behaviour. The combination of these attributes distinguish the emotions from sensations, feelings and moods. HUMAINE's proposal for EARL (Emotion Annotation and Representation Language)[edit] The emotion annotation and representation language (EARL) proposed by the Human-Machine Interaction Network on Emotion (HUMAINE) classifies 48 emotions.[2] Parrott's emotions by groups[edit]

Dunning–Kruger effect The Dunning–Kruger effect is a cognitive bias in which low-ability individuals suffer from illusory superiority, mistakenly assessing their ability as much higher than it really is. Psychologists David Dunning and Justin Kruger attributed this bias to a metacognitive incapacity, on the part of those with low ability, to recognize their ineptitude and evaluate their competence accurately. Their research also suggests corollaries: high-ability individuals may underestimate their relative competence and may erroneously assume that tasks which are easy for them are also easy for others.[1] Dunning and Kruger have postulated that the effect is the result of internal illusion in those of low ability and external misperception in those of high ability: "The miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others Original study[edit] Supporting studies[edit] Studies focusing on other cultures[edit]

The Unreasonable Effectiveness of Mathematics in the Natural Sciences The Unreasonable Effectiveness of Mathematics in the Natural Sciences is the title of an article published in 1960 by the physicist Eugene Wigner.[1] In the paper, Wigner observed that the mathematical structure of a physical theory often points the way to further advances in that theory and even to empirical predictions. The miracle of mathematics in the natural sciences[edit] Wigner begins his paper with the belief, common to all those familiar with mathematics, that mathematical concepts have applicability far beyond the context in which they were originally developed. Based on his experience, he says "it is important to point out that the mathematical formulation of the physicist’s often crude experience leads in an uncanny number of cases to an amazingly accurate description of a large class of phenomena." He then invokes the fundamental law of gravitation as an example. The deep connection between science and mathematics[edit] Responses to Wigner's original paper[edit] 1. 3. 4.
