Der grönländische Eisschild verliert aufgrund der globalen Erhitzung 30 Millionen Tonnen Eis pro Stunde und damit 20% mehr als bisher angenommen. Manche Forschende fürchten, dass damit das Risiko eines Kollaps des Amoc größer ist als bisher angenommen. Der Eisverlust ist außerdem relevant für die Berechnung des Energie-Ungleichgewichts der Erde durch Treibhausgas-Emissionen. https://www.theguardian.com/environment/2024/jan/17/greenland-losing-30m-tonnes-of-ice-an-hour-study-reveals

Experimenting can be interesting. I've tried using spreadsheet software like Google Sheets or Excel which can be simple and useful methods that don't lose significant functionality. I did separate sheets for zettels, sources, and the index. Each zettel had it's own row with with a number, title, contents, and a link to a source as well as the index.

Google Docs might be reasonably doable, but the linking portion may be one of the more difficult affordances to accomplish easily or in a very user-centric fashion. It is doable though: https://support.google.com/docs/answer/45893?hl=en&co=GENIE.Platform%3DDesktop, and one might even mix Google Docs with Google Sheets? I could see Sheets being useful for creating an index and or sources while Docs could be used for individual notes as well. It's all about affordances and ease of use. Text is a major portion of having and maintaining a zettelkasten, so by this logic anything that will allow that could potentially be used as a zettelkasten. However, it helps to think about how one will use it in practice on a day-to-day basis. How hard will it be to create links? Search it? How hard will it be when you've got thousands of "slips"? How much time will these things take as it scales up in size?

A paper-based example: One of the reasons that many pen and paper users only write on one side of their index cards is that it saves the time of needing to take cards out and check if they do or don't have writing on the back or remembering where something is when it was written on the back of a card. It's a lot easier to tip through your collection if they're written only on the front. If you use an alternate application/software what will all these daily functions look like compounded over time? Does the software make things simpler and easier or will it make them be more difficult or take more time? And is that difficulty and time useful or not to your particular practice? Historian and author David McCullough prefers a manual typewriter over computers with keyboards specifically because it forces him to slow down and take his time. Another affordance to consider is how much or little work one may need to put into using it from a linking (or not) perspective. Using paper forces one to create a minimum of at least one link (made by the simple fact of filing it next to another) while other methods like Obsidian allow you to too easily take notes and place them into an infinitely growing pile of orphaned notes. Is it then more work to create discrete links later when you've lost the context and threads of potential arguments you might make? Will your specific method help you to regularly review through old notes? How hard will it be to mix things up for creativity's sake? How easy/difficult will it be to use your notes for writing/creating new material, if you intend to use it for that?

Think about how and why you'd want to use it and which affordances you really want/need. Then the only way to tell is to try it out for a bit and see how one likes/doesn't like a particular method and whether or not it helps to motivate you in your work. If you don't like the look of an application and it makes you not want to use it regularly, that obviously is a deal breaker. One might also think about how difficult/easy import/export might be if they intend to hop from one application to another. Finally, switching applications every few months can be self-defeating, so beware of this potential downfall as you make what will eventually need to be your ultimate choice. Beware of shiny object syndrome or software that ceases updating in just a few years without easy export.

Revisit the question from earlier about dialectical notes and "separate sheets". See: https://hypothes.is/a/QJ-tsNKvEe20jVORiPEA0g

The authors recommend making dialectic notes on "a separate sheet (or sheets"). Presumably here, this is because the notes don't relate to just one text, but to multiple. This doesn't seem to have the same underlying cause or need as that suggested by Konrad Gessner or others to keep separate sheets for individual ideas, but we should revisit this when we get to chapter 20.

Synopsis: Maggie Delano looks at some of the affordances supplied by Tana (compared to Roam Research) in terms of providing better block-based user interface for note type creation, search, and filtering.

These sorts of tools and programmable note implementations remind me of Beatrice Webb's idea of scientific note taking or using her note cards like a database to sort and search for data to analyze it and create new results and insight.

It would seem that many of these note taking tools like Roam and Tana are using blocks and sub blocks as a means of defining atomic notes or database-like data in a way in which sub-blocks are linked to or "filed underneath" their parent blocks. In reality it would seem that they're still using a broadly defined index card type system as used in the late 1800s/early 1900s to implement a set up that otherwise would be a traditional database in the Microsoft Excel or MySQL sort of fashion, the major difference being that the user interface is cognitively easier to understand for most people.

These allow people to take a form of structured textual notes to which might be attached other smaller data or meta data chunks that can be easily searched, sorted, and filtered to allow for quicker or easier use.

Ostensibly from a mathematical (or set theoretic and even topological) point of view there should be a variety of one-to-one and onto relationships (some might even extend these to "links") between these sorts of notes and database representations such that one should be able to implement their note taking system in Excel or MySQL and do all of these sorts of things.

Cascading Idea Sheets or Cascading Idea Relationships

One might analogize these sorts of note taking interfaces to Cascading Style Sheets (CSS). While there is the perennial question about whether or not CSS is a programming language, if we presume that it is (and it is), then we can apply the same sorts of class, id, and inheritance structures to our notes and their meta data. Thus one could have an incredibly atomic word, phrase, or even number(s) which inherits a set of semantic relationships to those ideas which it sits below. These links and relationships then more clearly define and contextualize them with respect to other similar ideas that may be situated outside of or adjacent to them. Once one has done this then there is a variety of Boolean operations which might be applied to various similar sets and classes of ideas.

If one wanted to go an additional level of abstraction further, then one could apply the ideas of category theory to one's notes to generate new ideas and structures. This may allow using abstractions in one field of academic research to others much further afield.

The user interface then becomes the key differentiator when bringing these ideas to the masses. Developers and designers should be endeavoring to allow the power of complex searches, sorts, and filtering while minimizing the sorts of advanced search queries that an average person would be expected to execute for themselves while also allowing some reasonable flexibility in the sorts of ways that users might (most easily for them) add data and meta data to their ideas.

Jupyter programmable notebooks are of this sort, but do they have the same sort of hierarchical "card" type (or atomic note type) implementation?

Who is using these forms in practice? I'd love to see some examples.

This sort of set up could be used with some outlining functionality to streamline the content creation end of common note taking practices.

Is anyone using a spreadsheet program (Excel, Google Sheets) as the basis for their zettelkasten?

What scholar is being referenced here as using larger slips and suggesting others do likewise?

sheets / slips

Interesting choice of translation for "Die Kartei" by the translator. Some may have preferred the more direct "file".

Historically for this specific time period, while index cards were becoming more ubiquitous, most of the prior century researchers had been using larger sheets and frequently called them either slips or sheets based on their relative size.

Beatrice Webb in 1926 (in English) described her method and variously used the words “cards”, “slips”, “quarto”, and “sheets” to describe notes. Her preference was for quarto pages which were larger pages which were likely closer to our current 8.5 x 11” standard than they were to even larger index cards (like 4 x 6".

While I have some dissonance, this translation makes a lot of sense for the specific time period. I also tend to translate the contemporaneous French word “fiches” of that era as “sheets”.
