The German word Zettelkasten translates to “slip box,” but it’s really a philosophy about how knowledge grows.

In the 20th century, sociologist Niklas Luhmann filled wooden boxes with thousands of index cards, each containing a single idea. But here’s the magic: every card was linked to others through a simple numbering system. Over decades, these connections compounded into a vast web of thought that produced 70 books and 400+ scholarly articles.

I’ve adapted this system for the digital age. Instead of index cards, I maintain living notes. Documents that evolve as I learn, research, and encounter new insights. Topics connect. Ideas compound. Understanding deepens.

These notes are my version of it: a growing archive of interconnected thoughts on sound, perception, data, and the messy process of making sense of it all.


Living Books

Comprehensive, book-length guides that grow over time. These are deep dives into topics I’m actively researching and refining.


Living Notes

Shorter, focused notes on specific topics. Quick references, frameworks, and insights that I refine as I learn more.


These documents are never "finished." They evolve as my understanding deepens, connections emerge, and new insights arrive.
