Mapping Social Networks. The growth of social networks such as Facebook and MySpace has introduced the idea of the 'social graph' into common parlance. the social graph is Watch this short video describing the proof of concept Vizter social network browser visualisation: Vizter explanatory video. How does vizter allow you to identify friends you have in common with other people?

How does vizter help the user identify possible communities in the social graph? If you have a Facebook account, there are several tools that you can use to visualise your friends network on there (requires adding the visulisation as a Facebook application). Here are some of the tools that I'm aware of: Touchgraph frinds'n'photos browser;Nexus social graph browser;FriendwheelFacebook Mutual Friend Network Visualization in FlashFriends visulisation in Many Eyes: this application will mine your friends network and produce a data output that will let you visualise your friends network using the Many Eyes network visualisation tool.

The Best Tools for Visualization. Visualization is a technique to graphically represent sets of data. When data is large or abstract, visualization can help make the data easier to read or understand. There are visualization tools for search, music, networks, online communities, and almost anything else you can think of. Whether you want a desktop application or a web-based tool, there are many specific tools are available on the web that let you visualize all kinds of data. Here are some of the best: Visualize Social Networks Last.Forward: Thanks to's new widget gallery, you can now explore a wide selection of extras to extend your experience.

Designers Giorgia Lupi (New York) and Stefanie Posavec (London) recently launched a fascinating postcard project called Dear Data. Each week the two data artists measure one aspect of their daily lives and then represent that information with a drawing on a postcard. Every Monday they put their postcards into the mail to journey across the ocean to the other and begin collecting data for the next postcard. Having only met twice in person, this project is as much about the two of them getting to know one another as it is about finding creative ways to record details of their own lives.

There are so many interesting details in the notes they make for each other; instructions on how to decode the often extremely abstract ways they’ve represented their findings, as well as little tidbits about their day. I love the analog and imperfect nature of the project; I think it makes the idea of data visualisation more accessible. Dear Data Project Website. 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. 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. 14. 13. 12. eyePlorer 11.

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 : On considère que l'on peut découpler le mouvement des électrons de celui des noyaux, en estimant que leur mouvement est beaucoup plus lent que celui des électrons : on les considère comme fixes dans l'étude du mouvement des électrons de la molécule. On traite alors les distances internucléaires comme des paramètres. Elle a une conséquence calculatoire immédiate, qu'on appelle hypothèse adiabatique. Pour fixer le contexte de cette méthode, considérons l'interaction coulombienne d'un proton et d'un électron. De l'ordre de kg). . Et , de numéro atomique . . Où, avec. Approximation de Born-Oppenheimer. The Joke’s on You | Steve Almond.

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.

The Onion, once a satirical broadsheet published by starving college students, is now a mini-empire with its own news channel. Stewart and Colbert, in particular, have assumed the role of secular saints whose nightly shtick restores sanity to a world gone mad. 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. Fans will find this assessment offensive. You got that? The Essayification of Everything. The Stone is a forum for contemporary philosophers and other thinkers on issues both timely and timeless. 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. It seems that, even in the proliferation of new forms of writing and communication before us, the essay has become a talisman of our times. What do I mean with this lofty expression? Let’s start with form’s beginning. The possibilitarian is a virtuoso of the hypothetical. How to Live Without Irony.

Falling Men: On Don DeLillo and Terror, Chris Cumming. New York Police officers are seen under a news ticker in Times Square in New York, April 16, 2013. (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. The worst one came in late December, when a package of dynamite exploded in the baggage-claim area at LaGuardia Airport, killing eleven. DeLillo’s fictional treatments of terrorism and mass shootings are extensive. Texas again. 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. What linguists and anthropologists object to are pronouncements about good and bad language which are founded in aesthetics, fashion, or prejudice, but served up as objective truths with a side order of superiority. Less important (but still irritating) is the way many prescriptivists get wound up in inane controversies about punctuation, which has nothing to do with spoken language, but still will be filed under "proper grammar.

" Prescriptivists can be purposefully obtuse and more than bellicose when arguing a position. Sociocultural linguists are actually interested in prescriptivism. 1. 2. 3. 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. Legendary design duo Charles and Ray Eames shaped the mid-century modern aesthetic and influenced the voice of design for decades to come. They were also prolific filmmakers, perhaps best known for the iconic Powers of Ten film. In this fantastic Q&A from 1972, found on the excellent compilation The Films of Charles & Ray Eames and reproduced here in House Industries’ typography journal, Madame L’Amic of the Musee des Art s Decoratifs in Paris asks Charles Eames 29 questions about design, covering everything from the balance between form and function to the role of computers in creativity to the impact of influences.

I’m particularly taken with this bit affirming remix culture and combinatorial creativity: [Is design] a creation of an individual? You can also listen to the full audio of the interview in this Japanese video of questionable legality: William Burroughs at 100: Thurston Moore on seeing him watch Patti Smith at CBGB, his response to Kurt Cobain’s suicide and ‘cut-up’ songwriting | The Collected Works of Kevin EG Perry. “Panorama of the City of Interzone. Opening bars of East St. Louis Toodleoo … at times loud and clear then faint and intermittent like music down a windy street…. The room seems to shake and vibrate with motion…” That was how William S Burroughs introduced the world to the ‘Interzone’ in his heroin-and-hashish-soaked 1959 novel ‘Naked Lunch’.

Those few bars of Duke Ellington were just the beginning. Rarely has a writer had as much of an impact on rock’n’roll as Burroughs, who was born 100 years ago today on 5 February 1914. Kurt Cobain was such a big fan that he played discordant guitar on a spoken-word performance called ‘The “Priest” They Called Him’. While Burroughs lived all over the world, including in London and in Tangier, in north Morocco, the city that inspired ‘Interzone’, he is perhaps most associated with the New York scene that he inhabited with fellow poets and writers like Allen Ginsberg and Jack Kerouac.

What was your first impression of Burroughs? Did you meet him? A Gravity's Rainbow Companion: Sources and Contexts for Pynchon's Novel - Steven C. Weisenburger. Behavioral economics. There are three prevalent themes in behavioral finances:[3] Issues in behavioral economics[edit] Behavioral finance[edit] The central issue in behavioral finance is explaining why market participants make systematic errors contrary to assumption of rational market participants.[1] Such errors affect prices and returns, creating market inefficiencies. It also investigates how other participants take advantage (arbitrage) of such market inefficiencies.

Behavioral finance highlights inefficiencies such as under- or over-reactions to information as causes of market trends (and in extreme cases of bubbles and crashes). Other key observations include the asymmetry between decisions to acquire or keep resources, known as the "bird in the bush" paradox, and loss aversion, the unwillingness to let go of a valued possession. Quantitative behavioral finance[edit] Quantitative behavioral finance uses mathematical and statistical methodology to understand behavioral biases.

Thoroughly Conscious Ignorance: How the Power of Not-Knowing Drives Progress and Why Certainty Stymies the Evolution of Knowledge. Philosophy Karl Popper: Discussion Popper's Problem of Induction. Quotes Karl Popper. Discussion of Metaphysics / Philosophy of Karl Popper's Problem of Induction & the Evolution of Absolute Truth Karl Popper Pictures, Quotes 'Objective Knowledge' In my opinion, the greatest scandal of philosophy is that, while all around us the world of nature perishes - and not the world of nature alone - philosophers continue to talk, sometimes cleverly and sometimes not, about the question of whether this world exists.

They get involved in scholasticism, in linguistic puzzles such as, for example, whether or not there are differences between 'being' and 'existing'. (Popper, 1975) Introduction to Karl Popper The philosophy of Karl Popper and Thomas Kuhn are very similar - they argue that truth is evolving and can never be absolutely known. As it turns out they were wrong, thus ultimately harmful for the evolution of Human Knowledge. I apologise if this is abrupt - but we can now deduce what reality is without opinion, so this is stated absolutely simply because it is true. References. Nietzsche: Beyond Good and Evil. A brilliant young man, he was appointed professor at the University of Basel aged 24 having not even finished his degree. His evanescent philosophical life ended 20 years later when he went insane and died shortly afterwards. Nietzsche's argued that the Christian system of faith and worship was not only incorrect, but harmful to society because it allowed the weak to rule the strong - it suppressed the will to power which was the driving force of human character.

Nietzsche wanted people to throw of the shackles of our misguided Christian morality and become supermen - free and titanic. However, without God he felt that the future of man might spiral into a society of nihilism, devoid of any meaning; his aim was for man to realise the lack of divine purpose and create his own values.

The core of Nietzsche's work, including Thus Spake Zarathustra (1883-92), Beyond Good and Evil (1886), The Birth of Tragedy (1872) was to find a meaning and morality in the absence of God. The Century of the Self. 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. Freud's daughter Anna Freud, a pioneer of child psychology, is mentioned in the second part, as well as Wilhelm Reich, one of the main opponents of Freud's theories.
