Speedcubing tracker · Aug 2026 – present

A command-line speedcubing timer and solve tracker that computes official WCA averages (ao5/ao12/ao100) with DNF and +2 penalties, tracks improvement trends and personal bests, estimates the odds of beating a target time, and generates HTML progress reports with dependency-free SVG charts.

Program I & Program II

Stanford University Mathematics Camp · 2024, 2025

One of 40 students worldwide; abstract algebra & number theory (2024), algebraic topology (2025).
Presented on constructible n-gons via field theory (2024) and the Poincaré–Hopf theorem (2025), which you can play with below.

The hairy ball theorem

From my SUMaC II talk. Drag to spin the ball, or grab a glowing cowlick and push it around.

Push a cowlick anywhere you like and the hair re-combs around it, but you can never make it lie completely flat: every continuous tangent field on the sphere vanishes somewhere, so a cowlick always survives. By Poincaré–Hopf, the cowlicks' indices always add up to χ(S²) = 2.

Just for fun!

My 3x3 best: seconds

Scramble a cube, then press and hold the timer (or the space bar) and let go to start. Press again to stop.
