Today

Background: Unrelenting pressure and an “always-on” culture can leave no time for genuine rest among young adults. While playing video games has been noted to afford cognitive escapism and relaxation, critical questions remain about the influence of popular video games, such as Super Mario Bros., and their potential effects on young adults’ burnout risk.

people who fetishize east-asians are cringe… but could those people involve east-easians themselves? i talk about various topics such as aegyo, asianfishing, orientalism, and the potential positives of self-fetishization. also, i need better lighting.

A nice walk from homotopy to Lie theory to category theory to combinatorics.

the tension between the black and asian american community is complicated. with asian american immigrants being both foreigners and racial minorities, how does this position them in a black-white socioracial framework?

An animated explainer on homotopy groups. Discusses geometric intuition for π₁/π₂/π₃ using loopspaces of metric spaces. Includes an original, nonstandard visualization of the Hopf map.

Beautiful typesetting and animation. Homotopy is really weird; surprised that people turned this stuff into type theory.

Ranked #1 among over 400 entries in the 2025 Summer of Math Exposition (SoME4) competition

A series of videos covering the history of de Broglie’s famous matter wave theory. Bro is a genius, FRFR. Bro was doing unification before it even had a name. We ought to re-trear his work.

In this video, I present one of the most influential formulations of classical physics — Hamiltonian mechanics. This is a walk through the birth of Hamiltonian mechanics and how Hamilton extended Lagrange’s work into a new, elegant formulation that would go on to influence quantum theory, statistical mechanics, and dynamical systems.

In this video, I present an overview of symmetries in physics, passive vs. active transformations, and how to derive Noether’s theorem from the Euler-Lagrange equations. Different examples are presented in detail to show how the invariance under specific symmetries can be used to construct conserved quantities.

A crash course in quantum physics.   I explain states and transition probabilities between states in quantum physics, and the basic rule for computing transition probabilities.

Surprisingly straightforward.

Ben Sparks uses simulations for a new insight into Möbius loops.

Very nice video demonstating the power of using the computer when doing mathematics.

In which some very meta background music comes out of the background, and goes nuts.

You know how saying a word over and over again makes it lose all meaning? Somehow, this guy invoked the same feeling using music. This idea does make for surprisingly interesting film score, tho. Would be perfect for a psychological thriller.
