Turning questions into things you can test.

More about me

I explore how physics, computation, and design can turn abstract questions—and everyday constraints—into things people can test and use.

Selected work

Four ways of turning questions into practice.

A model, a product, a mechanism, and a community question—each shaped by a constraint worth understanding.

Letter World

Overview

A focused vocabulary-practice platform. An owner-reported 45-day snapshot records 308 students and 310,692 practice responses.

When Is a Two-State Tunneling Model Reliable?

Overview

An independent computational study of how numerical reliability and approximation error change across a controlled parameter grid.

Freeing the Handlebar

Overview

A frame-mounted shifter I designed and tested, now installed on my bike using the bottle-cage mounting points to move the control off the handlebar.

Rural Physics Initiative

Overview

An in-progress effort to design low-cost, engaging physics experiments for schools with limited laboratory access.

Model / Product / Mechanism / Community

One habit of mind, applied in different places.

Each project begins by making a question specific enough to test—and by being honest about what the current evidence can support.

  1. 01

    Model

    Understand physical systems

    Test where a simplified model remains reliable, and preserve the regions it cannot yet resolve.
  2. 02

    Product

    Build usable learning tools

    Turn a learning gap into a repeatable system, then revise it through real feedback.
  3. 03

    Mechanism

    Redesign a physical constraint

    Use the bike frame itself to rethink a control-routing problem encountered while riding.
  4. 04

    Community

    Widen access to experiments

    Build local evidence, teacher input, safety review, and a responsible path toward a pilot.

Briefly

Ideas become more useful when their limits are visible.

I am a high school student based in Xiamen, China. I notice where a model, product, mechanism, or educational system meets a constraint—and try to develop a testable response. That might mean checking a quantum approximation, revising a vocabulary game, moving a bicycle control, or finding out what a teacher needs before designing an experiment kit.
