15 Effective Tools for Visual Knowledge Management. Since I started my quest a few years ago searching for the ultimate knowledge management tool, I’ve discovered a number of interesting applications that help people efficiently organize information.

15 Effective Tools for Visual Knowledge Management

There certainly is no shortage of solutions for this problem domain. Many tools exist that offer the ability to discover, save, organize, search, and retrieve information. However, I’ve noticed a trend in recent years, and some newer applications are focusing more on the visual representation and relationship of knowledge. I believe this is in part due to the wider adoption of mind mapping (and concept mapping), and leveraging concepts and advances in the semantic web community. Most traditional personal knowledge management (PKM) or personal information management (PIM) applications offer the same basic set of features: These are essential features, however don’t offer too much to the more visually-inclined knowledge junkies. 15.

Approximation de Born-Oppenheimer

En chimie quantique, le calcul des niveaux d'énergie et des fonctions d'onde d'une molécule (même de taille modeste) est une tâche extrêmement lourde. L'approximation de Born-Oppenheimer (BO) permet de la soulager grandement. Cette méthode a été publiée en 1927 par Born et Oppenheimer et est toujours utilisée en chimie quantique.

L'hypothèse de Born et Oppenheimer peut s'exprimer ainsi : Approximation de Born-Oppenheimer. The Joke’s on You. Steve Almond [from The Baffler No. 20, 2012] Among the hacks who staff our factories of conventional wisdom, evidence abounds that we are living in a golden age of political comedy. The New York Times nominates Jon Stewart, beloved host of Comedy Central’s Daily Show, as the “most trusted man in America.” His protégé, Stephen Colbert, enjoys the sort of slavish media coverage reserved for philanthropic rock stars. Bill Maher does double duty as HBO’s resident provocateur and a regular on the cable news circuit. But their sanctification is not evidence of a world gone mad so much as an audience gone to lard morally, ignorant of the comic impulse’s more radical virtues.

Our lazy embrace of Stewart and Colbert is a testament to our own impoverished comic standards. The Essayification of Everything. The Stone is a forum for contemporary philosophers and other thinkers on issues both timely and timeless.

The Essayification of Everything

Lately, you may have noticed the spate of articles and books that take interest in the essay as a flexible and very human literary form. These include “The Wayward Essay” and Phillip Lopate’s reflections on the relationship between essay and doubt, and books such as “How to Live,” Sarah Bakewell’s elegant portrait of Montaigne, the 16th-century patriarch of the genre, and an edited volume by Carl H. Klaus and Ned Stuckey-French called “Essayists on the Essay: Montaigne to Our Time.” The essayist samples more than a D.J.: a loop of the epic here, a little lyric replay there, all with a signature scratch on top.

(REUTERS/Brendan McDermid) Some terrorist attacks become cultural obsessions, while others are forgotten completely. There were three bombings in New York City in 1975, none of which I’ve ever heard talked about, each of which would probably shut down the city if it happened now. In January, Puerto Rican separatists set off dynamite in Fraunces Tavern in downtown Manhattan, killing four businessmen—the same number of fatalities, incidentally, that led us to close the airspace over Boston last week. In April, four separate bombs went off in midtown Manhattan on one afternoon, damaging a diner and the offices of several finance firms. These were underground disturbances, moments of disorder that helped warp the culture, even if they weren’t absorbed or even remembered. American Anthropological Association: English As She Is Spoke. Written by Rosina Lippi Green In discussions about language, prescriptive types generally scorn academic linguists; they see us as language anarchists who reject the very idea of rules.

In fact, any linguist will tell you that all human language is structured and rule governed. Charles Eames on Design: Rare and Wonderful Q&A from 1972. By Maria Popova A lucid reflection on the role and culture of design by one of the most iconic and influential designers of all time.

This series is about how those in power have used Freud's theories to try and control the dangerous crowd in an age of mass democracy. Sigmund Freud, the founder of psychoanalysis, changed the perception of the human mind and its workings profoundly.

His influence on the 20th century is widely regarded as massive. The documentary describes the impact of Freud's theories on the perception of the human mind, and the ways public relations agencies and politicians have used this during the last 100 years for their engineering of consent. Among the main characters are Freud himself and his nephew Edward Bernays, who was the first to use psychological techniques in advertising. He is often seen as the father of the public relations industry. Heidegger: Thinking the Unthinkable. German philosopher Martin Heidegger addressed the central question of human existence full on, by examining how human self-awareness depends on concepts of time and death. His preoccupation with ontology - the form of metaphysical inquiry concerned with the study of existence itself - dominated his work.
