Polymath
A deployed learning graph that is becoming the public reading layer for course notes and blog posts, with a deliberate public/private data boundary.
Dong YaoZe · research · engineering · open learning
I research difficult questions, build useful tools, and turn what I learn into durable public notes.
Mathematics, research notebooks, software projects, study notes, writing, and selected downloads — organized so you can start with a few representative pieces or explore the full archive.
Selected
Starting points
A small, hand-picked set that spans the different kinds of work here. Representative rather than newest, and deliberately kept short.
ProjectsTranslation
Linear Algebra Done Wrong — Chinese translation
A maintained Chinese translation of an open linear-algebra textbook, re-aligned against the author's 2026 edition.
ResearchResearch notebook
Beyond Slater — research notebook
A research notebook that re-frames an early effective-nuclear-charge project as a falsifiable model search. No new rule is claimed yet.
ProjectsAgent infrastructure
TeXPage Bridge and DeepSeek Harness plugin
A broker that lets editing agents compile LaTeX in the cloud without ever holding browser sessions, Git credentials, or signed URLs.
ProjectsInteractive science
VisualChem
Twelve bilingual, scroll-driven chemistry stories in which the diagrams, animations, and equations are one computed state.
These are starting points, not the full archive.

Choose a section
Six permanent sections hold everything that is public. Each index is complete for its kind of work.
- Projects Public software, tools, and long-lived project stories, plus a catalog of every public repository. Open index →
- Research Questions, models, evidence, revisions, negative results, and open uncertainty. Open index →
- Writings Essays, poetry, fiction, and other writing, presented in the original language. Open index →
- Study Notes Reusable explanations; the graph-connected course notes are read in Polymath. Open index →
- Downloads Deliberately public artifacts that are safe and useful to redistribute. Open index →
- About Who this is, how the site is organized, and the publishing principles behind it. Open index →
Also: Education, a secondary catalog of books, solution sets, and translations, each with its rights status stated plainly.
Build with context
Projects explain what problem they solve, where their boundary is, and where the code lives. GitHub holds the current state; this site holds the story.
Research with a trail
Questions, evidence, revisions, negative results, and open uncertainty stay visible. Project status and scientific conclusion are kept apart.
Publish deliberately
Public pages and downloads are selected on purpose, not mirrored from working folders. Rights-sensitive material stays out until it is cleared.
