Zettelkasten method and math related sciences

Hello everyone,

I am an electrical engineer PhD student and I try to use my Zettelkasten effectively, but there is a thing that puzzles me. In his book "How to take smart notes", Sohren suggests taking small notes for your slip-box. In my case, many of the ideas involve mathematical equations and graphs. I currently use the Zkn3 app, which sadly does not have math notation support. I would like to hear, how the physicists, mathematicians and engineers among you, build a Zettelkasten with equations and stuff.

Is it a good idea to have figures and mathematical equations on a Zettel ?

Any advice would be welcome.

Thank you.

  • My research area is in machine learning and I deal frequently with equations and figures. For the figures, I just add them as images within the note. If it is a table from a paper, normally I just copy the relevant information into a markdown table.

    For equations, I use latex. Many programs will render latex equations within markdown. My current workflow is to use The Archive. If I am looking at a note with a significant amount of math (or figures), then I use the shortcut to open it in an external editor (Typora). So far this is working well for me, but would be interested if anyone has a better approach.

    Hey Ulver, I'm a physicist. Keeping everything simple, you could have your ZK notes in

    • one folder as LaTeX files (light-weight text files)
    • another folder with photos from the blackboard, book pages from the library, screenshots from articles. Graphs as png images.
    • a third folder with all the pdf articles you accumulate. The standard convention for the filename of articles is (Author'sLastName)(YearPublished). Remember Smith2003.pdf and you'll be set. If there are more authors then SmithJ2003 for Smith and Jones and if Smith published two papers in the same year go for Smith2003a and Smith2003b. Keeping the convention for filenames like this is great for referencing to those articles with other people, everyone will know which paper you're talking about.

    Lastly, write the equations in LaTeX in your text files. Ask faculty members for a little guidance on LaTeX if you're new to it. Then hit StackExchange or the hundreds of tutorials online. LaTeX templates are a great resource to learn from.

    Use BibDesk, Mendeley or something similar for managing your articles and books. In those reference managers your Smith2003.pdf will have the full title, year, authors, abstract, tags.

    Use structure notes as much as possible so your notes are organized and allow your ZK to be scalable.

    My workflow is much like @boxcariii's

    This screenshot shows my Latex and Mathjax workflow. The Archive is on the left, and the right is Marked 2 in the "Stream to Marked Preview" node. I haven't yet needed to delve into the latex and mathjax syntax much beyond mostly chemical formulas. There is lots of help here and all over the web on the syntax to use. You probably know all the correct markdown syntax already.

    I was surprised to learn that most markdown previewers also support HTML. I have, at times, resorted to this as a time saver for simple, quick formulas.

    How I use latex and mathjax may change and hopefully be easier when The Archive switches to Multi-Markdown as its editor. We'll see.

  • Thanks guys for your responses.

    I am using Latex for 5 years, so I am quite familiar with it. The thing is, that when you create a PDF from your tex document in Texmaker or another program, a whole bunch of files are created along with a PDF file. Doesn't it make the folder with your slip-box look cluttered ?

    With respect to literature notes, I use a folder where I store all my pdf research articles with the format [Year-Author] Title, whereas I use the same format on Joplin, an opensource alternative to Evernote that allows creating notes with support for Latex based mathematical equations.

    But with respect to the Zettelkasten, the only software that I found easy to use is the zkn3. I am on Linux, so I cannot use the Archive. Obsidian led to a very confusing slip-box and I quickly abandoned it. Is there any articles for building a Zettelkasten from tex files ?

    From what I found here https://tex.stackexchange.com/questions/11123/prevent-pdflatex-from-writing-a-bunch-of-files it seems like there's no way to prevent the extra files. If you were using macOS I'll recommend you Hazel https://www.noodlesoft.com/whats-new-in-hazel-5/. This application will filter out automatically any file inside a directory according to rules that you set up. In this case you'll filter any non pdf to be deleted or moved into another folder.
