In fact, it became a sort of dual brain for me. Thanks for producing such a great piece of software. Today I read a Wired article about SuperMemo: http://www.wired.com/medtech/health/magazine/16-05/ff_wozniak?currentPage=1 SuperMemo is a flashcard program that calculates the best time to show you a piece of information in order to optimise its retention. Apparently, the methodology is very useful to load lots of information into the brain. I think that memory is very important, because when the information is within the brain, it is much easier to make connections and see the whole picture. While reading the article, I thought that the supermemo algorithm should be implemented within org-mode. After all, all my information is in .org files. My *Org-Agenda* could show me, everyday, the items I should to check again in order to retain them in my brain. In fact, watching SuperMemo's screenshots, I saw that this program has many features that are similar to org-mode. For example, look at this: http://www.supermemo.com/help/images/thumb/9/9b/Contents_window.jpg/528px-Contents_window.jpg I'm not a programmer at all, therefore I cannot implement this myself. Do you know if somebody already started such a project? Are there any plans to do so?

That would be a good idea. The other thing that supermemo implements is incremental reading http://en.wikipedia.org/wiki/Incremental_reading I don't know much about it, as apparently only supermemo implemented it. But I guess it would be also well adapted to org-mode. Did you ever try it?

As the Wikipedia article explains, incremental reading (IR) is a mechanism that eases the input of new material that is to be processed at various stages, incrementally. First, you read an article's content normally; when you think you've come across an interesting portion of text (say, a sentence, paragraph, or section), you extract it (think highlighting); these extracts will be new sub-documents (in SM parlance, topics) that will be shown at a later date, as scheduled by the spaced repetition algorithm. When these topics come to your screen, you will re-process them (e.g. by shortening and rephrasing of sentences) to finally convert them into typical question/answer items that are common to most SR products (SM, anki, mnemosyne, etc). You can think of it as an integrated pre-processing step to build Q/A material. Its incremental nature helps tackle difficult material, as it is possible to postpone topics that require supporting data or better explanations before coming back to them, as well as counter factors such as frustration and boredom. On the other hand, the fact it is fed to a scheduling process (spaced repetition) is quite beneficial as you know it will come back to you, and because each exposure to the material aids in establishing the memory trace, making future recall easier. For this reason, incremental reading techniques seem to benefit the most from a spaced repetition algorithm (a la Supermemo). For org-mode to support IR techniques in a rudimentary way, a notion of document and sub-documents/extracts seems vital; if these could be separate sections in an org-file (corresponding to a single article), then to support the flow of information in IR there could be a mechanism to make copies of the highlighted material (say, the active region) into a new subsection: ==== file: ATitle.org ==== * Article: A Title :article: Lorem ipsum [mark]dolor sit amet[point], consectetur adipisicing elit ==== M-x org-make-extract ==== file: ATitle.org ==== * Article: A Title... :article: ** A Title: Lorem ipsum :topic: dolor [mark]sit[point] amet ==== M-x org-make-cloze-deletion M-x org-dismiss-section ==== file: ATitle.org ==== * DISMISSED Article: A Title... :article: ** DISMISSED A Title: Lorem ipsum... :topic: *** A Title: dolor :item: **** QUESTION dolor [...] amet **** ANSWER sit ==== M-x org-drill ==== ** A Title: dolor :item: *** QUESTION dolor [...] amet *** ANSWER... ==== More ideas: Topics with memorized/dismissed states could be worked around TODO states or tags, which should not propagate to children (memorized means "in the learning process"). Categories (as in a knowledge tree) could be implemented with #+CATEGORY or tags. Encoding of parameters in items (such as next repetition date, repetition history, A-factor, forgetting index, etc.) could be worked around drawers (though some of this data perhaps shouldn't be user-editable). An old version of the SM algorithm (SM-2, current is SM-11): http://www.supermemo.com/english/ol/sm2.htm (Incidentally, anki and mnemosyne are based on SM-2, therefore some source code should be available) Addendum: to experience incremental reading in Supermemo, keep in mind the only IR-enabled versions are Supermemo 2000 or later for Windows. There are trial versions available for download. Also, note that the knowledge management abilities related to IR take a bit of time and focused practice to develop.
