    1. “It is from the attempt of expressing themselves thatunderstanding evolves, rather than the other way around,” he maintains.

      —Woff-Michael Roth

      Actively attempting to express oneself is one of the best methods of evolving one's understanding.

      Link this to the ideas related to being forced to actively manufacture the answer to a question is one of the best ways to learn.

    2. A simple request to “move your handsas you explain that” may be all it takes. For children in elementary school, forexample, encouraging them to gesture as they work on math problems leadsthem to discover new problem-solving strategies—expressed first in their handmovements—and to learn more successfully the mathematical concept understudy.

      Given the benefits of gesturing, teachers can improve their pedagogy simply by encouraging their students to move their hands while explaining things or working on problems.

      Studies with elementary school children have shown that if they gesture while solving math problems led them to discover and understand new concepts and problem solving strategies.

      link this with prior idea of handwriting out annotations/notes as well as drawing and sketchnoting ideas from lectures

      Students reviewing over Cornell notes also be encouraged to use their hands while answering their written review questions.

    1. That number has been drastically reduced to hundreds but police are expecting more people to arrive this weekend.

      Is this true? If so, why not act then?

    1. Purple Numbers are a clever hack because you can work them into many existing kinds of systems. You don’t have to reinvent the document format, or cut it up into many pieces. You just stick a few ID tags in useful places. It’s like dog-earing the page of a book to find your way back.

      As permanently identified paragraph level locations, purple numbers might allow one to combinatorically rearrange sets of notes or facts in a variety of different ways.

      This pattern might be seen in earlier instantiations of note taking tools like the German zettelkasten.

      Documents might be generated by creating playlists of purple numbers in particular (useful) orders.

      An interesting perspective. Worth comparing the ideas of learning and remembering and what relationship they have to each other.

    1. In the early chapters Ahrens outlines the general form and method for taking notes for a zettelkasten, though he's not overly descriptive of the method and provides no direct examples.

      In the middle chapters he talks broadly about learning research and how the zettelkasten method dovetails with these methods.

      He does this almost as if he's a good teacher showing the student an outline of what to do and why, but leaving it up to them to actually do the work and experimentation to come up with their own specific methods of use to best suit their purposes. This allows them to do the work themselves so that they have a better chance of following a simple, but easy set of rules, but in a way that will allow them to potentially more quickly become an expert at the practice.

      “The one who does the work does the learning,” writes Doyle (2008, 63) [Section 10.5]

      In some sense, he's actively practicing what he preaches as a teaching device within his own book!

      I think that this point may be actively missed by those readers who aren't actively engaging with and converting his ideas into their own and doing the work which he's actively suggesting.

    2. he best-researched and mostsuccessful learning method is elaboration. It is very similar to whatwe do when we take smart notes and combine them with others,which is the opposite of mere re-viewing (Stein et al. 1984)Elaboration means nothing other than really thinking about themeaning of what we read, how it could inform different questions andtopics and how it could be combined with other knowledge

      Elaboration is thinking deeply about the meaning of what we've read, how it could inform or answer different questions, and how it can be linked or combined with other knowledge. It is one of the best-researched and most successful learning methods. While it seems to have some subtle differences, it sounds broadly similar to the Feynman technique and is related to the idea of writing questions based on one's notes in the Cornell note taking method.

    3. While it is obvious that familiarity is not understanding, we have nochance of knowing whether we understand something or just believewe understand something until we test ourselves in some form.

      The Cornell notes practice of writing questions in the empty left column as a means of testing knowledge can be an effective tool after taking notes to ensure that one has actually learned and understood the broad concepts. They can also be used for spaced repetition purposes as well.

      Valuable though they may be as teaching and learning tools, they don't figure directly into the idea of permanent notes from a zettelkasten perspective.

    4. Reading with a pen in yourhand is the small-scale equivalent of a lecture.

      Active reading with a pen in your hand and the creation of smart notes is a small-scale equivalent of a full introductory lecture from the perspective of Richard Feynman's technique for testing understanding.

      Active reading is roughly equivalent to the idea of reading with a pen in your hand or showing evidence of a mind at play.

    5. Taking smart notes is the deliberate practice ofthese skills. Mere reading, underlining sentences and hoping toremember the content is not.

      Some of the lighter and more passive (and common) forms of reading, highlighting, underlining sentences and hoping to understand or even remember the content and contexts is far less valuable than active reading, progressive summarization, comparing and contrasting, and extracting smart or permanent notes from one's texts.

    6. Project-related notes can be: · comments in the manuscript· collections of project-related literature· outlines· snippets of drafts· reminders· to-do lists· and of course the draft itself.

      Project notes can be kept in folders either inside or outside of the zettelkasten itself, but they technically shouldn't be a permanent part of it. Perhaps it's better to think of them as a workbench or play space for ideas as they're forming into a finished piece of writing. Once the piece is done, the play space has served its purpose and can be cleaned up.

    7. Permanent notes, on the other hand, are written in a way that canstill be understood even when you have forgotten the context theyare taken from.

      Integrate this into the definition of permanent notes.

      Fleeting notes are context collapse (context apocalypse?) just waiting to happen.

    8. These kinds of notes are just reminders of athought, which you haven’t had the time to elaborate on yet.

      Integrate this into the definition of fleeting notes.

    9. Just collecting unprocessedfleeting notes inevitably leads to chaos.

      Collecting fleeting notes and not processing them into something more useful and permanent will eventually end in abject failure.

      An example can be seen in the note taking of Joachim Jungius in 1657. He compiled approximately 150,000 slips (also known as scraps) with excerpts and ideas without any sort of order, arrangement, index or reference system. Following his death his students and heirs could make nothing of the massive "scrap heap". As a result, Vincent Placcius in De Arte Excerpendi (1689) specifically warns against this practice (p. 72).

    10. Students should not only learn to write papers, butalso learn facts, be able to discuss their ideas in seminars and listencarefully to lectures

      I wonder if there are any labs which not only have journal clubs, but have a shared note taking system or zettelkasten as well to keep as a community resource.

      I'm sure there are probably a few lab wikis in existence.

      Are professors keeping public note collections that they share with students or fellow researchers?

    11. Academic writing in itself is not a complicated process thatrequires a variety of complicated tools, but is in constant danger ofbeing clogged with unnecessary distractions. Unfortunately, moststudents collect and embrace over time a variety of learning andnote-taking techniques, each promising to make something easier,but combined have the opposite effect.

      Not highlighted in this context but it bears thinking about, Ahrens is looking at writing in particular while many note taking techniques (Cornell notes, SQ3R, SQ4R, etc.) and methods geared at students are specific to capturing basic facts which may need to be learned, by which I mean memorized or at least highly familiar, so that they can later be used in future analysis.

      Many of these note taking concepts are geared toward basic factual acquisition, repetition, and memorization and not future generative thought or writing applications.

      It's important to separate these ideas so that one can focus on one or the other. Perhaps there are contexts within which both may be valuable, but typically they're not. Within the zettelkasten context the difference between the two may be subtly seen in the conception of "literature notes" and "permanent notes".

      Literature notes are progressive summarizations which one may use to strengthen and aid in understanding and later recall. These may include basic facts which one might wish to create question/answer pairs for use in spaced repetition programs.

      Permanent notes have a higher level of importance, particularly for generative writing. These are the primary substance one wants to work with while the literature notes may be the "packing peanuts" or filler that can be used to provide background context to support one's more permanent notes.

      Compare this with: https://boffosocko.com/2021/12/22/different-types-of-notes-and-use-cases/

    12. Make literature notes.

      Related to literature notes, but a small level down are the sorts of basic highlights that one makes in their books/reading. For pedagogy's sake they're a sort of fleeting note that might be better rewritten in a progressive summarization form. Too often they're not, but sit there on the page in a limbo between the lowest form of fleeting note and a literature note.


      Hierarchy of annotations and notes: - fleeting notes - highlights - marginalia marks: ?, !, ⁕, †, ‡, ⁂, ⊙, doodles, phatic marks, tags, categories, topic headings, etc., - very brief annotations - literature notes (progressive summaries) - permanent notes

    13. Make permanent notes.

      The important part of permanent notes are generating your own ideas and connecting (linking them densely) into your note system. The linking part is important and can be the part that most using digital systems forget to do. In paper zettelkasten, one was forced to create the first link by placing the note into the system for the first time. This can specifically be seen in Niklas Luhmann's example where a note became a new area of its own or, far more likely, it was linked to prior ideas.

      By linking the idea to others within the system, it becomes more likely that the idea can have additional multiple contexts where it might be used and improve the fact that context shifts will prove more insight in the future.

      Additional links to subject headings, tags, categories, or other forms of taxonomy will also help to make sure the note isn't lost completely into the system. Links to the bibliographical references within the system are helpful as well, especially for later citation. Keep in mind that these categories and reference links aren't nearly as valuable as the other primary idea links.

      One can surely collect ideas and facts into their system, but these aren't as important or as interesting as one's own ideas and the things that are sparked and generated by them.

      Asking questions in permanent notes can be valuable as they can become the context for new research, projects, and writing. Open questions can be incredibly valuable for one's thinking and explorations.

    14. Make literature notes. Whenever you read something, make notesabout the content. Write down what you don’t want to forget or thinkyou might use in your own thinking or writing. Keep it very short, beextremely selective, and use your own words.

      Literature notes could also be considered progressive summaries of what one has read. They are also a form of practicing the Feynman technique where one explains what one knows as a means of embracing an idea and better understanding it.

    15. Make fleeting notes. Always have something at hand to write withto capture every idea that pops into your mind.

      Fleeting notes are similar to the sorts of things one would have traditionally kept in a waste book.


      Francesco Sacchini recommended the use of two notebooks:

      “Not unlike attentive merchants... [who] keep two books, one small, the other large: the first you would call adversaria or a daybook (ephemerides), the second an account book (calendarium) and ledger (codex).” —Francesco Sacchini "Chapter 13". De ratione libros cum profectu legendi libellus. Wurzburg. p. 91. (1614).

      (See also Blair, Ann M. (2004). "Note taking as an art of transmission". Critical Inquiry. 31 (1): 91. doi:10.1086/427303.)

      The root word ephemeral in this context is highly suggestive of the use and function of fleeting notes.


      The Latin word "ephemerides" can also be translated as "newspaper", useful for only a short period of time.


      Recall also that in a general sense Cicero contrasted the short-lived memoranda of the merchant with the more carefully kept account book designed as a permanent record.

      Reference: Cicero (1930). Pro Quinto Roscio comoedo oratio,"The Speeches". Translated by Freese, John Henry. Cambridge, Massachusetts. pp. 278–81.

    16. Every intellectual endeavour starts with a note.

      I like the framing of the idea that "Every intellectual endeavour starts with a note." as the idea of a note could potentially transcend literacy to include oral cultures as well.

    1. No bound to riches has been fixed for man

      He refutes, bound is what you put in

    2. The master is only the master of the slave; he does not belong to him, whereas the slave is not only the slave of his master, but wholly belongs to him.

      Tie to state - you belong to the state, but the state does not belong to you

    3. Thus the state is by nature clearly prior to the family and to the individual

      Could be discussing importance

    4. As in other departments of science, so in politics, the compound should always be resolved into the simple elements or least parts of the whole. We must therefore look at the elements of which the state is composed, in order that we may see in what they differ from one another, and whether any scientific distinction can be drawn between the different kinds of rule

      Argues against Plato's idea of household rank, but also on board with idea tht happiness comes from life in society

    5. THE POLITICS

      General notes: how men relate to the state & how personal relations reflect that relationship - Community over family

    1. 1

      Note: 1. Eighty-four percent of autocracies from 1946 to 2010 had a ruling party (Cheibub, Gandhi, and Vreeland 2010), and 57 percent of these parties failed to outlive the founding leader (Meng 2019).

    2. 2

      Note: 2. I use the terms “authoritarian regime” and “dictatorship” synonymously. I also use the terms “dictator,” “authoritarian leader,” and “president” interchangeably.

      Mostly a review of the prior article with little new.

    2. Its design allows you to jump between moving fast and slow through your notes and has the benefits of active recall built-in, making your memories stickier.

      This method also presupposes that one is taking notes solely for memorizing facts and helping to support basic understanding.

      What about for analysis, comparison, synthesis, generation of entirely new ideas?

    1. https://words.jamoe.org/highlight-question-and-answer/

      A somewhat disingenuous reframing of the Cornell notes method. They've given it a different name potentially for marketing purposes to sell in a book. At least HQ&A is a reasonable mnemonic for what the process is.

      They do highlight the value of modality shift from reading to thinking about how to formulate a question and answer as a means of learning. They don't seem to know the name or broader value of the technique however.

      This question technique is also highlighted in the work of Andy Matuschak and Michael Nielsen. Cross reference: https://andymatuschak.org/prompts/ and their quantum mechanics course experiments.

    1. And if gender identity is self-created, why must other people accept it as reality? If we should be free to choose our own gender reality, why can some people impose their idea of reality on others just because they identify as transgender?

      Why should we respect people?

    2. What does it even mean to have an internal sense of gender? What does gender feel like? What meaning can we give to the concept of sex or gender—and thus what internal “sense” can we have of gender—apart from having a body of a particular sex?

      It's hard to describe, espacially if you're not trans to understand what it is. But you're not trying and it shows

    3. Transgender Catechism

      Relating being trans to being in a religion

    4. This is a remarkable claim, not least because the argument recently was that gender is only a social construct, while sex is a biological reality. Now, activists claim that gender identity is destiny, while biological sex is the social construct.

      A better way to word the changes in attitude towards gender and sex is, With more information from Transgender people as well as genetic tests showing that chromosomes don't always equal sex, in addition to intersex people existing, the lines between sexes are shown to be less clear than previously thought. So, Gender identity is the best way for someone to be referred to.

    5. Many of those who feel distress over their bodily sex know that they aren’t really the opposite sex, and do not wish to “transition.” They wish to receive help in coming to identify with and accept their bodily self. They don’t think their feelings of gender dysphoria define reality.

      Appeal to incredulity (Difficult to understand) Confirmation bias

      This is true but for the wrong reasons. Many trans people, myself included deal with not only Gender dysphoria, but imposter syndrome. This is only made worse by people like the author telling us things like these. Learning I am a boy and accepting that for myself took a long time, and coming out to others who reacted positivly has helped me tremendously. I am happier in myself and that's improved my relationships. I can't accept my body the way it is because it is objectivly female. I want my chest to be flat and it is objectivly not. I want to have a deep voice beecause I know and as you hear it you can hear, it is objectively high pitched. The person writing this article has clearly never spoken to an out trans person or tried to show compassion to them before coming to this conclusion.

    6. Most people who suffer from gender dysphoria are not activists, and many of them reject the activists’ claims

      True, but this is because we are gaining better language to describe ourselves and our identities as time goes on.

    7. But even this one violates current dogma. Some activists have complained that the Genderbread Person looks overly male.

      Being very nitpicky.Definitely check for something here. Maybe relevance?

    8. Does the proper dosage of medicine depend on the patient’s sex or gender identity?

      Loaded question.

      Also the answer is a person's hormone levels.

    1. Moving my (web) reading list to sticky notes because I never remember to check it on my computer.

      Wall with stickie note sized print outs taped to it. They contain a QR code, presumably linking to the thing they want to read with a Title and author below it.

    1. https://jamesg.blog/2022/01/04/simple-taxonomies/

      Keeping things simple is a useful thing, particularly when there aren't any consuming applications that use that sort of complexity. A simple note with some tags can be incredibly versatile.

    1. In this spirit he castigated Alexander Harden as "an enemy of the spirit that was fed by a small mind with a large card index," taking up what appears to have been a common criticism of the author, who because of his style that relied overly much on quotations [Die Fackel, Heft 360-62 (1912)].

      Some of this critique relates to my classification about the sorts of notes that one takes. Some are more important or valuable than others.

      Some are for recall and later memory, some may be collection of ideas, but the highest seems to be linking different ideas and contexts together to create completely new and innovative ideas. If one is simply collecting sententiae and spewing them back out in reasonable contexts, this isn't as powerful as nurturing one's ideas to have sex.

    1. The margins, after all, are harrowingly thin for a .500 team that’s seen four of its six losses come by one score.

      Special teams played a role in 3 of those four games.

    1. I think smaller projects that are faster to build are better for research in this space. Building many smaller projects rather than large ambitious ones have helped me because I avoid getting too attached to one particular idea or product, and with smaller-scoped prototypes I can try many more iterations against the same question or problem. It also lowers the barrier to entry to try more risky ideas – “I’ll try this for a weekend” is much easier than “I’ll have to shift my schedule the next couple weeks to fit this in; is it worth that?” A culture of shorter, more atomic projects will also encourage everyone to break down large ideas into smaller ones that are individually testable, which I think is a good practice regardless of whether those ideas are for a product or an experiment. On the other hand, cycles that are too short obviously run the risk of keeping us from trying more ambitious or complex ideas.

      Atomizing projects and research ideas is very similar to the idea of the atomic note.

      If useful things can be turned into re-usable building blocks, then it can be easier to build and design larger and more complex systems out of them.

    1. Though firmly rooted in Renaissance culture, Knight's carefully calibrated arguments also push forward to the digital present—engaging with the modern library archives where these works were rebound and remade, and showing how the custodianship of literary artifacts shapes our canons, chronologies, and contemporary interpretative practices.

      This passage reminds me of a conversation on 2021-11-16 at Liquid Margins with Will T. Monroe (@willtmonroe) about using Sönke Ahrens' book Smart Notes and Hypothes.is as a structure for getting groups of people (compared to Ahrens' focus on a single person) to do collection, curation, and creation of open education resources (OER).

      Here Jeffrey Todd Knight sounds like he's looking at it from the perspective of one (or maybe two) creators in conjunction (curator and binder/publisher) while I'm thinking about expanding behond

      This sort of pattern can also be seen in Mortimer J. Adler's group zettelkasten used to create The Great Books of the Western World series as well in larger wiki-based efforts like Wikipedia, so it's not new, but the question is how a teacher (or other leader) can help to better organize a community of creators around making larger works from smaller pieces. Robin DeRosa's example of using OER in the classroom is another example, but there, the process sounded much more difficult and manual.

      This is the sort of piece that Vannevar Bush completely missed as a mode of creation and research in his conceptualization of the Memex. Perhaps we need the "Inventiex" as a mode of larger group means of "inventio" using these methods in a digital setting?

    1. Because of its geography, Australia is a neighbor and an observer of authoritarian countries as varied as China and Singapore. But its own fate, too, may turn on whether its people crave the feeling of safety and security that orders from the top confer, or whether they want to be free.

      This thought gets at an idea worth paying attention to.

    1. https://kimberlyhirsh.com/2019/04/01/dissertating-in-the.html

      A description of some of Kimiberly Hirsh's workflow in keeping a public research notebook (or commonplace book).

      I'd be curious to know what type of readership and response she's gotten from this work in the past. For some it'll bet it's possibly too niche for a lot of direct feedback, but some pieces may be more interesting than others.

      Did it help her organize her thoughts and reuse the material later on?

    1. Sketchnoting forces students to take ideas from a lesson and turn them into their own ideas. It also forces modality shifts.

      Reviewing over a lecture after the fact to create sketchnotes is incredibly similar to some of the point and purpose of Cornell Notes.

      While watching: https://www.youtube.com/watch?v=UOHcWhdguIY

    1. Another theoretician of the index card system, the German sociologist Niklas Luhman, whose so-called "Zettelkasten" (slip-box) has achieved independent fame in Germany, used to talk about this first analytic step as "reduction for the sake of [building] complexity." [9]

      Luhmann used the idea of "one card, one fact" as the first step of "reduction for the sake of [building] complexity."

      Historically reducing things to their smallest essential form or building blocks makes it much easier to build up new complex things from them.

      Examples of this include:

      • Reducing numbers to binary 1 and 0
      • tk

    1. One thing expected from the note-taking tools, makes me particularly skeptical: their collaborative/ public use. I think the lifecycle of notes cannot be continuous from capturing to communication, unless I forgo the possibility of cryptic, sloppy, abbreviated shorthand meant just for the “me later” that Magdalena Böttger depicted so aptly in 2005.

      Some of the value of notes being done and readable in public means that one typically puts a bit more effort into them at the start. This can make them much more useful and valuable later on. It also means that they usually have more substance and context for use by others in collaboration or other reuses.

      Short notes are often called fleeting notes which may or may not be processed into something more substantive. The ones that do become more substantive can more easily be reused in other future settings.

      Sonke Ahrens' book How to Take Smart Notes is one of the better arguments for the why and how of note taking.

    1. These all look interesting, but my primary worry is the ability to do cross-platform note taking with them. Perhaps worth delving into some more custom reviews, but the price points of these compared to my laptop versus the functionality and flexibility needs to improve greatly.

      They used transistors with a floating gate embedded in hybrid dielectrics at a nanoscale of size, and created a flexible array of these floating gate transistors. They coupled this with a pressure sensitive rubber sheet, and the result was a matrix that was able to read mechanical pressure and store it as an image.

      They test a high density, hemispherical image sensor array comprised of an atomically small MoS2 heterostructure that has the capability of releasing strain. They deem this device to be capable of being a soft retinal implant capable of various imaging elements.

      An elastomeric camera was created in the likeness of ant and beetle eyes. These cameras have close to full hemispherical shapes, at around 160 degrees. This hopes to copy arthropods who have wide-angle field of view, low aberrations, high acuity to motion and an infinite depth of field which are all difficult to replicate.

      first note

    1. I try to keep a note of what I read, which I probably would not do if I was not writing a blog

      I've recently shifted into a frame of mind where I think that, if I'm reading something (something that isn't obviously news or entertainment), I should be making notes. If I'm not making notes, then I'm probably wasting my time reading that particular piece of content.

    1. Fully integrated wearable sensor arrays for multiplexed in situ perspiration analysis

      A flexible sensor device was created with the ability to analyze different elements/compounds found within sweat such as glucose and sodium while also monitoring skin temperature. All of this is fully integrated within the system so no outside analysis is needed.

    1. One can now picture a future investigator in his laboratory. His hands are free, and he is not anchored. As he moves about and observes, he photographs and comments. Time is automatically recorded to tie the two records together. If he goes into the field, he may be connected by radio to his recorder. As he ponders over his notes in the evening, he again talks his comments into the record. His typed record, as well as his photographs, may both be in miniature, so that he projects them for examination.

      This is one of the most important aspects of the essay. Noting that he is continuously talking about the work of a scientist, he stresses the act of recording, of looking at reality. This is radically different from what Ahrens claims in his book "How to take Smart Notes", in which there is not a single hint to the fact that you must look through the window and not just into previous works.

    1. Preparatory remarks on the concept of an invisible hand: 1. The concept of an invisible hand plays a vital role in Karl’s analysis, even though Smith refers to it explicitly only twice in his two major books, once in The Wealth of Nations, and once in The Theory of Moral Sentiments(2005 [1759]). 2. While there is no generally agreed-upon definition of what is meant by an invisible hand, we shall employ the approach of Ullmann-Margalit (1978), which even Samuels (2011, 291) appears to regard as above reproach.

    2. more positive-sounding term spontaneous order than the more mystical-sounding invisible hand. Others, however, prefer to use another term. ‘I prefer the term “unintended order” to the more familiar “spontaneous order” because the former conveys that the system of order was not anyone’s intentional design without suggesting, as “spontaneous” might, that there is no way to account for the creation of the system’ (Otteson 2002, 6; see also Otteson 2007, 21).

      The importance of accountability is implied by introducing the term - "unintended order".

    3. Hayek is thus informing us that the framework of our analysis should include institutions that are ‘The results of Human Action but not of Human Design’.
    4. Hayek notes that if we confine our arguments to the natural and artificial realms confusion is bound to ensure: ‘... one would describe a social institution as “natural” because it had never been deliberately designed, while another would describe the same institution as “artificial” because it resulted from human action’ (Hayek 1967, 130)
    5. Preparatory remarks on the concept of an invisible hand: Suppose we identify an order in human affairs. On further investigation we ascertain that although the regularity came about as a result of human action, it did not arise from human deliberation. In other words, the order did not arise from human design. Under such conditions, says Ullmann-Margalit (1978, 263), we have an invisible hand explanation. She refers to this realm of things that results from human action but not from human design as a middle realm (1978, footnote 2) and cites Hayek (1966 and 1960) as her source. An example that comes most readily to the fore as an invisible hand explanation is the one associated with the creation of money (Ullmann-Margalit 1978, 264) or the emergence of language.

    1. Long before there was the Internet, there was the commonplace book — a creative and intellectual ledger of fragmentary inspirations, which a writer would collect from other books and copy into a notebook, often alongside his or her reflections and riffs. These borrowed ideas are in dialogue with the writer’s own imagination and foment it into original thinking. Over long enough a period of time — years, decades, often a lifetime — the commonplace book, while composed primarily of copied passages, comes to radiate the singular sensibility of its keeper: beliefs are refined, ideas incubated, intellectual fixations fleshed out, and the outlines of a personhood revealed. (Brain Pickings is, in an unshakable sense, a commonplace book.)

    1. Notions, Notes, Ideas and work notes

      My equivalent, as best as I can tell, is:

      • Permanent notes (atomic, linked concepts) = Notions
      • Temporary notes (half-formed thoughts, links, snippets, etc.) = Notes
      • Temporary notes initially, which later become permanent notes = Ideas (see later comment about why)
      • Admin notes (projects, tasks, meetings, etc.) = Work notes
    2. resources written down with the context added of how I found them and why I was interested

      I might also use Zotero to capture the original resource, with a few notes alongside it to explain why I kept it.

    3. They can be linked to Ideas, Notes or Notions, or may give rise to them, but they serve a purpose firmly rooted in ongoing work. They are always placed within the context, and folder, of a specific project

      Similar to how I've come to think of my "admin" or "operational" notes. They're instrumental in that they serve a purpose that is usually about moving some project forward.

    1. We encourage people to use the daily notes and to brainstorm and brain dump, and just write all the things they’re thinking. I think that the first thing that we’re interested in is, how do you build systems so that it’s easy for you to take those and gradually refine them?

      Conor is asking himself, how do you get people to take (daily) notes, and how do you get them to refine them.

    1. One major advantage of Lotus Notes is that it allows all the major information organization techniques to be used in one information space: outlines, graphics, hypertext links, relational databases, free (rich) text, expanding/collapsing reports, collapsi ng rich text sections, tabbed notebooks (like wizards) and tables. In other words, Lotus Notes is a hodgepodge of every information organization technique Lotus could think of, all thrown into one quirky product. As such, it is phenomenally satisfying a nd phenomenally frustrating at the same time.

      John Redmood claims that the advantage of Lotus Notes was that it brought together a wide range of information organization techniques: outlines, graphics, hypertext links, relational database, expanding/collapsing reports, collapsing rich text sections, tabbed notebooks and tables.

    2. With Lotus Notes, I can combine a hierarchically organized outline view of the documents, with full text searching, hypertext links and traditiona l relational database like reports (for example, a sorted view of items to do).

      What Lotus Notes allowed you to do is to combine a hierarchical organized overview, achieved through an outliner, with search, hyperlinks and relational-database-like reports. Lotus Notes also allowed you to organized different document formats (Word, emails, etc.)

      Provide trainees with a long period here to look at ucsc and play with it (time permitting)

    2. Recovering exon info

      So we have the original exon list, and we have a list of exon IDs, and the exon IDs on their own aren't very useful, so, let's find the exons in the original file which match these exon IDs

    3. ount the number

      Q: Ok, given last file, how would we figure this out? anyone know it in excel?

    4. fall into that exon?

      Again, numbers may be diff, compare with students

    5. Find exons with the most SNPs

      Q: What datasets do you have? How would you could about figuring this out? what information would you use?

    6. Again open the UCSC Main - table brows

      go back and do it again! It's the same thing over again

    7. When the dataset is green

      I usually just open the dataset and discuss what an exon is (genomic region w/ annotation.)

    8. Now set the following parameters:

      i'll read the parameters, but, they can check against the tutorial to be sure they're doing the right variables.

    9. Rename your history

      This is such an important step! So easy for students to get lost in their histories, remind them that it's normal, it happens to us, and life will be so much easier if they name things well.

    1. Le rapport demande d’anonymiser le lycée d’origine et de lui substituer une mesure de l’écart entre les résultats du bac et la notation au contrôle continu, dispositif testé cette année pour le bac.

    1. In Roam, each note becomes a node in your mind map, and there’s no central concept you have to start with. The map is fluid, with no hierarchy, no stacking, no linearity. It’s a giant knowledge web representing your notes and the connections between them.

      Just like the brain works.

    1. You should construct evergreen (permanent) notes based on concepts, not related to a source (e.g. a book) or an author.

      Your mental models are compression functions. You make them more powerful by trying to use them on new information. Are you able to compress the new information with an already acquired function? Yes, then you've discovered an analogous concept across two different sources. Sort of? Then maybe there's an important difference, or maybe it's a clue that your compression function needs updating. And finally, no? Then perhaps this is an indication that you need to construct a new mental model – a new compression function.

    1. Annotations—even inline marginalia which include your own writing—have very little informational value. They’re atomized; they don’t relate to each other; they don’t add up to anything; they’re ultra-compressed; they’re largely unedited. That’s fine: think of them as just a reminder. They say “hey, look at this passage,” with a few words of context to jog your memory about what the passage was about.Since you’re going to write lasting notes anyway, annotations need carry just enough information to recreate your mental context in that moment of reading. You wouldn’t want to rely on that long-term, since then you’d just have a huge pile of hooks you’d have to “follow” anytime you wanted to think about your experience with that book.

      Classical marginalia in books, according to Andy Matuschok, have little informational value. They are not interlinked, they're very compressed and usually unedited. But that's okay.

      Their purpose is to help you get back to the mental context you were in when you thought the passage was worth returning to.

    1. Update 2020-01-14: I now store my outlines as Structure Zettel. For more information what a Structure Zettel is see this post.

      An important update to this piece as Sascha's method evolved. Instead of using outlines to capture new notes, he started using structured notes.

      I suspect the reason for this is that a system with atomic notes and structured notes is more clear cut than a system that relies on work-in-progress outlines. The main difference being that a structured note will contain only notes and not some floating, un-evolved ideas.

    1. Instead of having a task like “write an outline of the first chapter,” you have a task like “find notes which seem relevant.” Each step feels doable. This is an executable strategy (see Executable strategy).

      Whereas Dr. Sönke Ahrens in How to Make Smart Notes seemed to be saying that the writing of a permanent note (~evergreen note) is a unit of knowledge work with predictable effort & time investment (as well as searching for relevant notes), Andy emphasizes only the note searching activity in this context.

    1. Ericsson claims (2016, p. 98) that there is no deliberate practice possible for knowledge work because there are no objective criteria (so, poor feedback), because the skills aren’t clearly defined, and because techniques for focused skill improvement in these domains aren’t known.

      According to Ericsson deliberate practice for knowledge work is not possible because the criteria are not objective (you don't know if you're doing well).

      This collides with Dr. Sönke Ahrens' contention that note taking, specifically elaboration, instantiates two feedback loop. One feedback loop in that you can see whether you're capturing the essence of what you're trying to make a note on and a second feedback loop in that you can see whether your note is not only an accurate description of the original idea, but also a complete one.

      Put differently, note taking instantiates two feedback loops. One for precision and one for recall.

    1. By contrast, when we’re working on a large work-in-progress manuscript, we’re juggling many ideas in various states of completion. Different parts of the document are at different levels of fidelity. The document is large enough that it’s easy to lose one’s place or to forget where other relevant points are when one returns. Starting and stopping work for the day feel like heavy tasks, drawing heavily on working memory.

      One key difference between working with atomic, evergreen notes compared to a draft manuscript is that the ideas in the manuscript are at different levels of evolution / fidelity. The ideas in the evergreen notes are all evolved components.

    1. Instead, nurture the wild idea and let it develop over time by incrementally writing Evergreen notes about small facets of the idea.

      If you cannot tackle a subject head on, tackle it obliquely by writing evergreen notes about facets of the idea.

      This is an interesting way of reducing the scope of, say, an essay, without sacrificing quality. Instead of writing the whole thing, just write an atomic piece about one of the concepts you need for the larger piece.

    1. The issue of the different layers is similar. If you chose software that doesn’t deal with those layers in a sophisticated way, you will not reap the benefits in the long term. Your archive will note work as a whole. I think that this is one of the reasons why many retreat to project-centered solutions, curating one set of notes for each book, for example. The problems that come with big and organic (= dynamic and living) systems is avoided. But so is the opportunity to create something that is greater than you.

      Interesting point where the author compares the barrier that is created between the editing and the writing mode in a wiki (which makes it more cumbersome to continue lines of thought) to the barriers that appear when you're not using the right software or conventions to structure your knowledge items, as well as to structure your knowledge items' structure.

    2. After a while, I did not only have structure notes that structure content notes, I also had structure notes that mainly structured sets of structure notes. They became my top level structure notes because they began to float on the top of my archive, so to say.

      After the need for a layer of Hub Notes a new need may emerge: to better organize the Hub Notes themselves. At this point you may want to introduce structure notes that structure sets of structured notes.

    3. Structure notes share a similarity to tags: Both point to sets of notes. Structure notes just add another element. They are sets with added structure. This added structure provides a better overview and adds to the utility of the archive.

      Structure notes or Hub Notes are similar to tags (or pages in Roam) in that they point to a collection of other notes (or pages in Roam). The only difference being that structure notes contain within themselves a structure which provides hierarchy and context.

    4. But after a while, you won’t be able to keep up. When I search for tags I get a couple hundred of notes. I have to review them to connect a note to some of them, or get a grasp of what I wrote and thought about a specific topic. Naturally, a need to organize the archive arises at this point. I can’t remember how many notes I had when I experienced this. I introduced hub-like notes when I had between 500 and 700 notes.1 I gave myself an overview of the most important notes on that topic.

      There seems to be an inflection point where your initial approach to organizing your Zettelkasten starts to fail (perhaps 500-700 notes). You'll simply have too many tags to choose from.

      At this point hub-like notes will be the next stage in the evolution of your Zettelkasten organization.

      The timing of activity for two predators (rockcod and dottyback, both reef fishes), and their common prey (the lemon damselfish) was compared. The behavior of the prey fish was determined to be a compromise between ideal times for efficient food capture and predator avoidance, with a particularly strong avoidance of the rockcod.

      For the present study on blacktip reef sharks, considering the influence of prey activity allowed researchers to explore if factors other than temperature were driving the behavior of sharks.

      This previous study of temperature-related shark behavior sought to study the feeding movements of dogfish: a relatively small shark that lives on the bottom of shallow marine environments. Researchers found that dogfish "avoided warmer water even when it was associated with greater food availability" showing a strong preference for colder waters when given the chance.

      The similar title of this paper ("Hunt warm, rest cool...") with that of the present study (."..Hunt Warm, Rest Warmer?) suggests that Dr. Papastamatiou and colleagues used the dogfish study as an important source of inspiration for their own study on blacktip reef sharks.

    1. 4 kinds of notes

      • Fleeting Notes
      • Literature Notes
      • Permanent Notes
      • Project Notes

      Organizing them are critical in notes. To do so you need a central system. So far, this is how it works with me:

      Literature Notes - Use either Kindle (while reading a book)

      Fleeting Notes - Custom Shortcuts (while on the phone) , custom Keyboard Maestro script (while on the mac). Also RoamResearch to see connection between ideas!

      Permanent Notes - Not yet made... Maybe I can use TiddlyWiki? or Notion?

      Project Notes - Devonthink

      And I sync all of them to the central notes folder present in document folder in the mac which is indexed by Devonthink.

      I guess this annotation itself is a literature notes.

    1. I am an avid reader, but I’m always struggling to memorize my learnings. I guess, that's why I started to write down my notes of books I enjoyed to read.
    1. Context notes are used as a map to a series of notes. A context note that outlines a more complex concept or broader subject, using links to other notes in the process. For example, while I’m reading a book, I build an outline of the things I find relevant, based on my highlights and notes of the book. Each of the outline’s items links to a separate note explaining the idea in more detail, and usually contains the highlighted text of the book.
    2. Each note is also given tags for classification. Good tagging helps with accuracy when searching. The method’s recommendation is to use tags for objects, and not for subjects4. In the same note, I write down the ideas I had in mind when highlighting the paragraph, or any connection that comes to mind during this process.

    1. La prise de notes est essentielle à la mémorisation et nécessite un entrainement régulier. Dans le cadre de l'enseignement à distance cela peut être un avantage

    2. Il n’est pas possible d’entraîner la mémoire de travail pour en améliorer la performance. En revanche, les autres aptitudes concernées peuvent faire l’objet d’un entraînement.

      A défaut de muscler la mémoire, on peut s'entrainer à prendre des notes.

    3. Toutefois avec la popularité croissante des cours en ligne, l’apprenant peut faire une pause à tout moment pour prendre des notes.

      Le fait de suivre des cours en ligne peut être un avantage.

    1. they are not meant to be substituted for a recollection that may fail. They constitute, rather, a material and a framework for exercises to be carried out frequently: reading, rereading, meditating, conversing with oneself and with others.

      Looking at one's academic notes in this sense, what if students were taught from a young age to view their notes and note taking as a continuous process which required frequent study and conversation? Even in college, students often only refer to notes as a means of remembering a specific fact, statement or concept.

    1. followed by failure to interbreed when partial connection between the oceans was reestablished

      Because of the long separation from one another, when some connection was established between either sides of the Isthmus, the shrimp pairs no longer had preferences to each other. Their extended sexual isolation probably had them adapted into altering their breeding behavior. ~J.D.A.

    2. Hence, pairs P5-C5 and P6-C6 probably separated during the period of marked shoaling and environmental divergence preceding final closure.

      P5-P6 pair were isolated from each other just before the final closing of the Panama seaway. This was due to shoaling of water and the environmental change that came with it. ~S.Z.

    8. Genetic divergence before final closure may have been facilitated by changing oceanographic conditions

      Genetic divergence was observed to have occured at different moments when oceanic changes like the haulting of certain currents across the Panama seaway and the shallowing of certain areas. (DV)

    9. Increasing species richness from 1 to 10 had twice the economic value of increasing species richness from 1 to 2.

      Each additional degree of species richness is worth less than the previous degree of richness in terms of economic value. Therefore, the economic value does not increase in direct proportion with the species richness, although they are correlated.

    1. predicted secondary structure

      Villordo and peers (2015) studied the cycle of how mosquito viruses could quickly adapt to different human host environments. The changes in RNA structures were examined in the dengue virus during host adaptation. The researchers discovered that the 3’UTR of RNA is modified during host adaptation, such as duplicating the structure to accommodate for beneficial mutations.

    2. Musashi-1

      Sakakibara and peers studied the Musashi-1 protein within a mouse and associated the protein with neural development. Musashi-1 was found to be highly enriched within the central nervous system of mammalian cells, regulate stem cell translation, and can differentiate into neurons through regulation.

      Li and others (2016) hypothesized that ZIKV can infect not only developing neuronal stem cells, but also adult brain cells. The results seen were that adults can be affected by the ZIKV. The adult would need to be triply deficient in the regulatory factor for interferon to allow the virus to take hold of the stem cells in the brain.

    5. effect on fetal neurodevelopment

      Cugola et al., (2016) found that ZIKV infects fetuses, causes intrauterine growth restriction (IUGR), and causes signs of microcephaly in mice. Data demonstrated that the infection of ZIKV into human brain organoids reduced proliferation and disrupted cortical layers. This indicates that ZIKV is able to cross the placenta and cause microcephaly by inducing apoptosis in cortical progenitor cells.
