New project: Canvi & temps Canvi & temps are two network browsing spaces built from a compilation of articles, pages, persons and links, all related with complexity in science. The research was carried out by Pau Alsina, Josep Perelló, Michele Catanzaro, Pere Monràs, Carles Tardío, Oriol Vallès, Irma Vilà and Santiago Ortiz. The project is in display at Arts Santa Mónica, in the context of a Cultures of Change exhibit. This historical (it includes citations since 1927) and transversal (it contains more than 30 categories of fields of knowledge) research offers and ample vision of the collection of aproaches, strategies and tactics, reseach methods and interests known as complexity science. Canvi & Temps offer two different ways of experiencing the contents of the network and its interrelations. Temps The interest in representing changes associated with complexity science through time (from 1927, which is the chronological reference in the field, up to date) rose from internal dialogue within our research group.
Presse - Article - Les journalistes français sur Twitter vus comme un graphe En suivant le paradigme méthodologique des Digital Methods, développé notamment par Richard Rogers à l’université d’Amsterdam (2009), nous pouvons envisager un groupe social qui s’active sur l’internet comme un graphe. Dans le cas qui nous intéresse ici, les nœuds du graphe sont les comptes des journalistes français sur Twitter et les connections entre eux sont constitués par des actions de communication comme les retweets et les mentions. Les premiers consistent à rediffuser tel quel un message d’un autre utilisateur. Les secondes consistent à inclure le nom d’un compte dans un message diffusé. Elles visent soit à s’adresser à cet utilisateur, soit à parler de lui. . Entre le 15 février et le 15 avril 2011 nous avons procédé à une cartographie de la Twittoshère journalistique française. . Carte 1 : vue d’ensemble de la Twittosphère journalistique française. Carte 2 : réseaux d’affinités à l’intérieur de la Twittosphère journalistique.
International Open Government Data Camp looks to build community There’s a growing international movement afoot worldwide to open up government data and make something useful with it. Civic apps based upon open data are emerging that genuinely serve citizens in a beneficial ways that officials may have not been able to deliver, particularly without significant time or increased expense. For every civic app, however, there’s a backstory that often involves a broad number of stakeholders. Governments have to commit to open up themselves but will in many cases need external expertise or even funding to do so. Citizens, industry and developers have to use the data, demonstrating that there’s not only demand but skill outside of government to put open data to work in the service of accountability, citizen utility and economic opportunity. Galvanizing the co-creation of civic services, policies or apps isn’t easy but the potential of the civic surplus attracted the attention of governments around the world. What will this camp change?
Canvi & Temps: An Exploration of Science Over Time Bestiario, the group behind 6pli and a number of other network projects, released their most recent project - Canvi & Temps - that explores the complexity of science since the early 1920s. The first part, Temps, is two linked charts stacked on top of each other. On top are individual articles and on bottom are tags that provide context to those articles. You'll probably be tempted to read the visualization as a stacked area chart, but that wouldn't quite work. It reminds me a lot of Bestiario's earlier Atlas of Electromagnetic Space. Then there's Canvi, which is a network view of tags and links: I'm not completely sure what I'm looking at with Canvi. The uniqueness of Canvi lays in the fact that it explores new node positioning techniques as well as their spatial relations. Yeah, I'm still not sure, but it's nice to look at. [Thanks, Jose]
The Elegant Universe: Pt 1 The Elegant Universe: Part 3 PBS Airdate: November 4, 2003 NARRATOR: Now, on NOVA, take a thrill ride into a world stranger than science fiction, where you play the game by breaking some rules, where a new view of the universe pushes you beyond the limits of your wildest imagination. This is the world of "string theory," a way of describing every force and all matter from an atom to earth, to the end of the galaxies—from the birth of time to its final tick, in a single theory, a "Theory of Everything." Our guide to this brave new world is Brian Greene, the bestselling author and physicist. BRIAN GREENE (Columbia University): And no matter how many times I come here, I never seem to get used to it. NARRATOR: Can he help us solve the greatest puzzle of modern physics—that our understanding of the universe is based on two sets of laws that don't agree? NARRATOR: Resolving that contradiction eluded even Einstein, who made it his final quest. S. BRIAN GREENE:The atmosphere was electric. S.
An Annual Report on One Man's Life Nick Bilton/The New York TimesNicholas Felton and his 2008 annual report. At the end of 2005, Nicholas Felton decided to publish a report that would chronicle his life over the previous year. He looked through his music archives to see how many songs he had listened to. He checked his airline ticket stubs to see how many miles he had flown. He aggregated the number of books read and photos taken. The following year, Mr. The tradition continues today. “I started collecting this data in 2005, and I hope to continue the collection process for at least a decade,” Mr. Although this data collection started with a simple curiosity, it also helped Mr. Each year, Mr. “I wanted to understand the bleeding edge of reporting and quantifying myself,” Mr. The works of Mr. But they also signal the kind of data collection that is becoming easier for all of us to do. It didn’t take long before strangers started asking how to create their own reports to quantify and collect information on themselves. Mr.
Analysing the water crisis in Australia's Marray-Darling Basin Here is how one might go about developing a model like this: 1. Create a model, a hypothesis - describing the problem, and consequences of attempted solutions to date 2. Elaborate the model with subject matter experts - from all walks, agriculture, industry, government, science, ... - Bring in other people's perspectives on the model 3. 4. 5. 6. 7. 8. 9. 10.
What topics science lovers link to the most Hilary Mason, chief scientist at bitly, examined links to 600 science pages and the pages that those people visited next: The results revealed which subjects were strongly and weakly associated. Chemistry was linked to almost no other science. Biology was linked to almost all of them. The interactive lets you poke around the data, looking at connections sorted from weakest (fewer links) to strongest (more links), and nodes are organized such that topics with more links between each other are closer together. Natural next step: let me click on the nodes. [Scientific American via @hmason]
La plus grande image du ciel jamais obtenue « meridianes La collaboration Sloan Digital Sky Survey-III, qui regroupe notamment des chercheurs du CNRS et du CEA, vient de mettre à la disposition de la communauté scientifique internationale le plus grand relevé du ciel jamais effectué, à l’occasion de la réunion annuelle de la Société Américaine d’Astronomie qui se tient à Seattle du 10 au 13 janvier 2011. Ce relevé a permis de construire une image dont on a extrait un catalogue de sources d’une grande partie du ciel en cinq couleurs et d’une qualité sans précédent (couverture du ciel, profondeur, précision de la mesure des luminosités). Ce catalogue, qui contient environ 470 millions d’objets (galaxies, étoiles, quasars…), fait l’objet d’une publication dans la revueAstrophysical Journal Supplements. L’image du ciel obtenue est d’une résolution d’un térapixel (mille milliards de pixels) et en cinq couleurs. Like this: J'aime chargement…
actuvisu Blog Simple Business Improvement Model This Southbeach Notation diagram illustrates some of the Southbeach Semantics in a simple model of a business. Its purpose is both to describe the situation and provide a basis from which to agree on key facts (e.g. there are insufficient sales) and priorities (e.g. marketing is the focus of attention). Southbeach models exist to support the analysis process in improving the situation. Thus, each element of a Southbeach model can provide a pivot point for improvement. Some examples are provided below. Here is how to read this diagram: Spending produces (arrow) materials which are used (small box end) by the manufacturing process to create (star) products which produce sales which produce revenue which produce profit. Note the short dashed lines across some of the effects. Here are some improvement alternatives illustrated by this diagram: All green boxes are useful, so increasing them is likely to increase the usefulness of the overall system. Blue boxes are improvement actions.
