Second-order logic In logic and mathematics second-order logic is an extension of first-order logic, which itself is an extension of propositional logic.[1] Second-order logic is in turn extended by higher-order logic and type theory. First-order logic quantifies only variables that range over individuals (elements of the domain of discourse); second-order logic, in addition, also quantifies over relations. For example, the second-order sentence Syntax and fragments[edit] A sort of variables that range over sets of individuals. Each of the variables just defined may be universally and/or existentially quantified over, to build up formulas. It's possible to forgo the introduction of function variables in the definition given above (and some authors do this) because an n-ary function variable can be represented by a relation variable of arity n+1 and an appropriate formula for the uniqueness of the "result" in the n+1 argument of the relation. or , where is a first-order formula. , or even as ∃SO. has the form

Speed reading History[edit] Psychologists and educational specialists working on visual acuity used a tachistoscope to conclude[1] that, with training, an average person could identify minute images flashed on the screen for only one five-hundredth of a second (2 ms). Though the images used were of airplanes, the results had implications for reading. Methods[edit] Skimming[edit] Another form of skimming is commonly employed by readers on the Internet. [edit] Meta guiding is the visual guiding of the eye using a finger or pointer, such as a pen, in order for the eye to move faster along the length of a passage of text. Commercial speed reading programs[edit] Speed reading programs are available through courses, both in person or software based, and manuals. One point of difference between the various speed reading courses is the assertions concerning subvocalization. Speed reading courses and books take a variety of approaches to the concept of reading comprehension. Legentas[edit] Reading Dynamics[edit]

Psychology Psychology is an academic and applied discipline that involves the scientific study of mental functions and behaviors.[1][2] Psychology has the immediate goal of understanding individuals and groups by both establishing general principles and researching specific cases,[3][4] and by many accounts it ultimately aims to benefit society.[5][6] In this field, a professional practitioner or researcher is called a psychologist and can be classified as a social, behavioral, or cognitive scientist. Psychologists attempt to understand the role of mental functions in individual and social behavior, while also exploring the physiological and biological processes that underlie cognitive functions and behaviors. While psychological knowledge is often applied to the assessment and treatment of mental health problems, it is also directed towards understanding and solving problems in many different spheres of human activity.

Philosophy - Guide to Happiness | Top Documentary Films We tend to accept that people in authority must be right. It's this assumption that Socrates wanted us to challenge by urging us to think logically about the nonsense they often come out with, rather than being struck dumb by their aura of importance and air of suave certainty. This six part series on philosophy is presented by popular British philosopher Alain de Botton, featuring six thinkers who have influenced history, and their ideas about the pursuit of the happy life. Socrates on Self-Confidence (Part 1) - Why do so many people go along with the crowd and fail to stand up for what they truly believe? Partly because they are too easily swayed by other people's opinions and partly because they don't know when to have confidence in their own. Seneca on Anger (Part 3) - Roman philosopher Lucious Annaeus Seneca (4BCE-65CE), the most famous and popular philosopher of his day, took the subject of anger seriously enough to dedicate a whole book to the subject.
Philosophy Philosophy is the study of general and fundamental problems, such as those connected with reality, existence, knowledge, values, reason, mind, and language.[1][2] Philosophy is distinguished from other ways of addressing such problems by its critical, generally systematic approach and its reliance on rational argument.[3] In more casual speech, by extension, "philosophy" can refer to "the most basic beliefs, concepts, and attitudes of an individual or group".[4] The word "philosophy" comes from the Ancient Greek φιλοσοφία (philosophia), which literally means "love of wisdom".[5][6][7] The introduction of the terms "philosopher" and "philosophy" has been ascribed to the Greek thinker Pythagoras.[8] Areas of inquiry Philosophy is divided into many sub-fields. These include epistemology, logic, metaphysics, ethics, and aesthetics.[9][10] Some of the major areas of study are considered individually below. Epistemology Rationalism is the emphasis on reasoning as a source of knowledge. Logic
Philosophy Ideas Database the free encyclopedia Straw man A straw man, also known in the UK as an Aunt Sally,[1][2] is a common type of argument and is an informal fallacy based on the misrepresentation of the original topic of argument. To be successful, a straw man argument requires that the audience be ignorant or uninformed of the original argument. The so-called typical "attacking a straw man" implies an adversarial, polemic, or combative debate, and creates the illusion of having completely refuted or defeated an opponent's proposition by covertly replacing it with a different proposition (i.e., "stand up a straw man") and then to refute or defeat that false argument, ("knock down a straw man,") instead of the original proposition.[3][4] This technique has been used throughout history in polemical debate, particularly in arguments about highly charged emotional issues where a fiery, entertaining "battle" and the defeat of an "enemy" may be more valued than critical thinking or understanding both sides of the issue. Origin[edit]
Theory of multiple intelligences The theory of multiple intelligences is a theory of intelligence that differentiates it into specific (primarily sensory) "modalities", rather than seeing intelligence as dominated by a single general ability. This model was proposed by Howard Gardner in his 1983 book Frames of Mind: The Theory of Multiple Intelligences. Gardner articulated seven criteria for a behavior to be considered an intelligence.[1] These were that the intelligences showed: potential for brain isolation by brain damage, place in evolutionary history, presence of core operations, susceptibility to encoding (symbolic expression), a distinct developmental progression, the existence of savants, prodigies and other exceptional people, and support from experimental psychology and psychometric findings. Gardner argues intelligence is categorized into three primary or overarching categories, those of which are formulated by the abilities.

Théorie du chaos Un article de Wikipédia, l'encyclopédie libre. Pour les articles homonymes, voir Chaos. La théorie du chaos traite des systèmes dynamiques rigoureusement déterministes, mais qui présentent un phénomène fondamental d'instabilité appelé « sensibilité aux conditions initiales » qui, modulo une propriété supplémentaire de récurrence, les rend non prédictibles en pratique à « long » terme. Introduction[modifier | modifier le code] Définition heuristique d'un système chaotique[modifier | modifier le code] Un système dynamique est dit chaotique si une portion « significative » de son espace des phases présente simultanément les deux caractéristiques suivantes : La présence de ces deux propriétés entraîne un comportement extrêmement désordonné qualifié à juste titre de « chaotique ». Qu'est-ce que la « théorie du chaos » ? La théorie du chaos est-elle née dans les années 1970 ?
