1. Diffraction

    Diffraction is normally taken to refer to various phenomena which occur when a wave encounters an obstacle. It is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings.[2] Very similar effects are observed when there is an alteration in the properties of the medium in which the wave is travelling, for example a variation in refractive index for light waves or in acoustic impedance for sound waves and these can also be referred to as diffraction effects. Diffraction occurs with all waves, including sound waves, water waves, and electromagnetic waves such as visible light, x-rays and radio waves. As physical objects have wave-like properties, diffraction also occurs with matter and can be studied according to the principles of quantum mechanics.

  2. Some notes on experimenting with the economics

    A few weeks ago, we launched the &AMP, Ampersand Make Production, a project in which people are supporting the production of cultural products.


    This is an experiment in the economics of production. Our first issue is a poster and a text: AMP001. The content is clearly influenced by the practice we developped to maintain and develop R-Echos (http://r-echos.net) and we called the issue “R-Echos issue 1”.

    * Recently Charlotte from Manystuff asked us to give more details about the ideas around &AMP - below I’m translating in english our answer to her request:

    Financing and the notion of Crowd Sourcing
    Instead of using a single source of finance, grant or sponsoring -we are seeking to establish a principle of distributed funding, like a p2p network. This principle is applied as well to the distribution since each share-holder/participant own a certain percentage of the real thing produced, and each of them is able to decide individually or collectivelly of the future of his or her share of the production.
    A series of economic experiments
    This project is for us a laboratory. The poster and the text of AMP001 (the first issue) are a first test tube. We are just starting to be able to draw early conclusions, it is for us a little bit like a reduced scale LHC: we are launching something and looking at the results depending on the parameters of the launch.
    An extension of R-echos (http://r-echos.net)
    R-Echos is a website, a selection of whatever we find, see, read and collect online, it is our daily best picks; it is a reblog that we have been maintaining for some years now. The poster of this first issue shows tangible objects that belongs to our every day life ans surround us: things on our desks, books in the shelves, visuals references that inspired us for some reasons - we consider those objects as being the sources of the project we develop and realise (like in programmation); we really consider R-Echos like being one of the source-code of Electronest.

    french version:
    le financement et la notion de crowd sourcing
    au lieu de s’en remettre à une seule source de financement, ou à un principe de sponsoring - nous cherchons à mettre en place un financement distribuée comme un réseau p2p. Ce principe s’applique également à la distribution, puisque chaque Share Holder possede un certain pourcentage de notre production et est en mesure de decider individuellement (ou cellectiveemnt) du futur de sa part de la production.
    une serie d’expériences économiques
    ce projet est un laboratoire pour nous. Le poster et le texte de AMP001, c’est une première éprouvette. On commence tout juste à pouvoir tirer des conclusions. c’est un peu comme un micro-LHC pour nous: on lance un truc, et on regarde ce que ça produit en fonction des paramètres de lancement
    une extension de R-Echos — http://r-echos.net
    R-Echos est un site internet, une sélection de ce que l’on lis/trouve online, nos “best picks” quotidien; c’est un reblog que l’on fait depuis quelques années déjà. Ce poster contient les objets qui nos entourent et nous inspirent — c’est un peu comme un code-source des choses que l’on fait, on considère le site de R-Echos comme étant un des codes-source de Electronest.

    * Here is also a short text I put on the facebook group a little while ago, it links the ideas of &AMP and the ones of etoy.SHARE:

    obviously, there’s some sort of inspiration taken from etoy.SHARE.
    In the & Make Production project, shares are project based and they determine if the project is interesting enough to make it to the production step. if not shareholders will be able to decide how they want the money to be used: refund, re-investment in the next publication or in the structure itself, etc.
    Shareholders are sharing the destiny of the project which we don’t control anymore.



  3. Nice reading this morning

    ● I quite like the final take on this matter; it emphasize a side of the  often criticised web2.0 not that often underlined: the recommandation principle where you trust your friend.

    Do we get the blogs we deserve? We vote by click, after all. Perhaps we shouldnt look at all those top 10 lists and Britney Spears photos. Successful blogs, such as Zen Habits, tend to balance the more fast-food type posts with longer, more complex ideas that will presumably keep readers coming back—although there are plenty of people who make a living posting dubious crap. Perhaps the escape route out of a hit-driven blogosphere is all of our newfound “friends.” The Internet has always been very good at counting page views but not so great at assigning value to whats actually in those pages. Facebook, FriendFeed, StumbleUpon, and the sharing feature of Google Reader have their annoying, nudgy aspects, but they allow us to rely on one another to sort out what is interesting and worthy. Put it on a T-shirt: Friends Dont Let Friends Read Bad Content.

  4. Laboratoire, a collection of recipes to produce culture, art and design with computers

    * This small edition is using a japanese binding - on one side of the paper sheet you have the content one can access normally through the pages, on the other side there’s a sort of diagram map of the project I did spatialised by keywords, where each keyword has its own coordinates and the project are placed in the middle of those points.
