information La granularité de l’information est définie comme le plus petit niveau de détail géré par un système ou une pratique, c’est l’unité physique ou logique qui a du sens pour le type de traitement auquel est soumise l’information enregistrée sur un support (définition de document). Ce peut être le volume au service de prêt d’une bibliothèque, ou le champ dans une base de données. Pour bien gérer l’information, il faut donc non seulement séparer le bon grain de l’ivraie (l’information gérée, document ou donnée, doit être pertinente pour le système en cause et fiable pour ses utilisateurs) mais il faut encore identifier le bon bon grain, c’est-à-dire la bonne taille des grains d’information (grain, morceau, paquet, objet, unité… d’information) pour chaque type de traitement, de même que, pour le raisin, le pâtissier manipule les grains, le détaillant les grappes et le grossiste des cageots.

Standard Naming Conventions For Electronic Records: The Rules/Anne Thompson Just two weeks ago, I had the opportunity to attend the 2012 Annual Meeting of the Society of American Archivists. Sporting the theme “Beyond Borders,” I was impressed by the recent transformation in how archives and archivists “do business”—how the technological and digital border has for the most part disappeared. Five years ago, the handful of conference sessions talking about digital records focused on how to capture and preserve born-digital records. This year, most sessions touched on digitization and digital records not as a novelty topic, but as one of today’s facts of life. An 1888 image of the Lucius D. Then and now on my phone.

Hydrogen Atom Scale Model [UPDATE: Well, now that I took the page down I've been hearing from teachers who found it useful even if it is a little inaccurate. So, when I get a little time I'm going to put something back here that will hopefully please everyone. Stay tuned.] So I used to have a page here that was a demonstration of how much empty space there is inside a hydrogen atom. It was based on something called the "Bohr model" of the atom, where you imagine the atom as a nucleus with electrons orbiting around it - kind of like a tiny solar system. The Bohr model has been obsolete for ages, but they still teach it in schools because it's a simple introduction to quantum physics and you can move on to more accurate models later. Keeping it working with various web browsers was a bit of a challenge. The other thing about the page is that it wasn't, strictly speaking, correct, as people who know Real Physics would periodically write and tell me. So, I've taken the page down, at least for now.
