adjoint VS obsidian-excalidraw-plugin

This idea shows up in essentially all scientific fields. It’s the idea of adjointness. Together with norm, they give you the idea of fixed points, (invariants, spectra, embeddings, braids etc).I'm

Lawvere's fixed point theorem is I think the best formulation of the idea

I've been putting together a brain dump on the topic

I’ve always thought that the completeness theorem was more interesting.

Also I really like approaching this from Lawvere’s fixed point theorem. https://ncatlab.org/nlab/show/Lawvere's+fixed+point+theorem

I have been thinking about some of this stuff

Yeah I have been realizing this lately as well. I have written up a bit on this

https://github.com/adamnemecek/adjoint/

Check the raw source there’s a bunch of links.

Fixed points, diagonalizations and eigenshit are all the same thing.

I think that there are like three concepts in math or the world, the concepts being the adjoint, norm and fixed point.

The concept of a fixed point is so ubiquitous.

Game theory, just liek essentially everything in math, physics and probability, and cs is about adjoints, norms, and fixed points https://github.com/adamnemecek/adjoint/

Nash equilibrium is a fixed point.

For me it was the idea of adjoint functors which is the central idea of category theory.

I wrote up a bit on it here https://github.com/adamnemecek/adjoint

I think I have somewhere around 1k notes. Startup time is not my concern as I keep it open all the time. It seems like I bumped into https://github.com/zsviczian/obsidian-excalidraw-plugin/issu... tl;dr: Minimal theme doesn't get along with Excalidraw.

I use excalidraw for almost everything. Brilliant tool. I already mentioned it in another response in this thread but using excalidraw inside obsidian via https://github.com/zsviczian/obsidian-excalidraw-plugin has been a game changer for me.

For those using Obsidian, the Excalidraw plugin plays really well within it.

Plug for Excalidraw:

Which, FWIW, supports Apple Pencil and iPad quite well since 2022:

As well as a seemingly evergreen release of the Obsidian plugin that gets people Doge levels of Such Wow:

The team based real time collaboration in Excalidraw+ is just fantastic. Glad to have a way to compensate the author:

I love my setup, and if you are going to spend money on an S8 (I have mine with paperfeel screenprotecor). Make sure to donate to the maintainer of the excalidraw plugin, he is doing awesome stuff: https://github.com/zsviczian/obsidian-excalidraw-plugin

For embedded drawings you can use Excalidraw for Obisidian.

As for community plugins, I currently have only the Excalidraw enabled on my Tab Ultra, but I haven't used it much so far.

The Obsidian Excalidraw plugin allows you to draw and write https://github.com/zsviczian/obsidian-excalidraw-plugin
