Notes
Choose a question to explore, or look up a detail you need now. These are different ways into the notes; there is no single reading order.
Explore a topic
- AI: start with tools, model choices, and agent workflows; use the theory chapters for the underlying concepts.
- Computing: algorithms, data structures, programming, systems, and everyday engineering tools.
- Math: calculus, linear algebra, probability, statistics, and optimization, arranged as stable subject chapters.
- Finance: returns and portfolio risk, forecasting and backtests, options, and macro scenarios.
- Misc: design, typography, music, and other interests.
For a guided introduction, use the learning paths. For a command, formula, or definition, open the Reference Shelf.
Find and return to an article
Use site search for a term or question. The note network also searches titles, summaries, aliases, and tags; select a note to explore its connections.
Follow an article link to read it; hover over or focus the link to see a read-only summary. Explore connections at the end of an article groups prerequisites, applications, and references. Previous and next chapter links follow sidebar order, not a required course.
