These relate to physics/modeling. I am going to hand wave a bunch.
If a system has to operate the same way under rotation/reflection, that strongly constrains what the system can be doing. Think crystals or isotropic forces or, in the day job, what should happen if you negate a feature going into a neutral network then retrain. Should it matter from which perspective you look at a thing?
If a system is continuous then smooth changes to inputs should cause smooth changes to outputs. The system probably will be robust to small perturbations because they will result in small output changes.
Not the author of the comment, but I can give an example of how it's used in physics. The first law of thermodynamics states (in a simplified form) that the energy into a system is equal to the energy out. So it's a symmetrical process. This means a lot of times we can calculate half of a thermodynamic process, (i.e the heat flow into a system), and know that, over a long enough period of time, the heat flow out of the system will be equivalent.
2. Collate all the interesting and useful information into one location
3. Condense this information into a blog post/article(optional: publish it in a 1. learning in public system - there might be errors in this)
4. Create a plan to use this knowledge in a project
5. Do a retrospective after using the knowledge and seeing results - What worked, what didn't work, what can be improved.
6. Add these points to your article
7. Use the knowledge in another project(ideally, in a different contexts) and do the last 3 steps. You might have to do it 3-4 times before you have a decent understanding of it.
So true! This has bugged me enough to create a introduction to Zettelkasten myself - just one page - https://binnyva.com/zettelkasten/ (wanted to keep it under 500 - but it went to 700 words).
Too many my friends are getting the idea Zettelkasten is complicated. When anyone express interest, I make it a point to tell them its a very simple concept. The complication is more in creating the behavior of taking notes rather than in using the system.
I use Obsidian - just markdown files. I use a Gatsby tool to convert it to a static site and upload it to my Digital Garden - https://notes.binnyva.com/
> Obsidian is adding features that most editors don't support which is kind of a vendor lock in
I'm assuming you mean block level referencing? Or Frontmatter at the beginning of the Markdown?
I haven't found this to be an issue - but worst case, you can choose not to use it.
Learning about Personal Knowledge Management systems. This includes Zettelkasten, PARA, Building a Second Brain and other systems. On the look out for more frameworks in this space.
