Hi, I'm Yunhao. I'm currently taking a break from my Master's in Physics at the University of Amsterdam and exploring different possibilities for what comes next.

This is my personal website, where I take notes, develop ideas, document projects, and share my works.

Here you'll find ideas, observations, and things I've made that may be valuable and worth your attention.
