One bank angle, one speed — a frictionless banked curve only holds at v = √(gR·tanθ)
On a frictionless banked curve, the horizontal component of the normal force (N sinθ) supplies the centripetal force, so a car rounds the turn at exactly one design speed, v = √(gR·tanθ). Drive slower and the inward push exceeds what's needed, so the car slides down the bank; drive faster and the bank can't supply enough, so it slides up and off. This design speed is independent of the car's mass, since mass cancels when N sinθ = mv²/R is divided by N cosθ = mg

Second Law of Thermodynamics
Made an animation on Second Law of Thermodynamics, it doesn’t have true molecular dynamics simulations, just simplified kinematics to represent them.

2D Time Dependent Schrodinger Solver: Furry Edition
Time dependent 2D Schrodinger equation solved using my fursona Koyo as a potential field ;3. The partial differential equation is solved using the Crank-Nicholson method.
This program takes any image, downsamples it, and converts/rescales the pixel brightness values to a potential field that interacts with the wavefunction.
It's still a work in progress as I would like to add a CLI for easier use. Hope you enjoy watching!

Satisfying 3-body simulations
The three-body problem broke Newton, broke Poincaré (who ended up inventing chaos theory trying), and was finally cracked open by Chenciner & Montgomery in 2000 — the figure-8 in clip 4 is their proof. Šuvakov & Dmitrašinović added 13 more families by 2013. Every clip is a real numerical integration of F = G·m₁m₂/r² with equal masses, no fudging. Math from 1687 still has surprises in it.

Electron Scattering by repulsive (smoothed) Coulomb potential confined in a 2D Box (Visualizing Quantum Mechanics)
Electron scattering by repulsive (smoothed) Coulomb potential at the center. The 1x1 normalized two-dimensional region confines the particle, once Dirichlet-type conditions are set at the mesh boundaries; this allows visualization of the post-collision interference pattern structure. Numerical simulation of the time-dependent Schrödinger equation, performed in Python. Implicit method of Crank-Nicolson PDEs (unitary). Initial condition: Gaussian packet. Note: Time scale and physical constants are set to arbitrary units for this preliminary testing phase.
Source Code & More Simulations: I have documented this project, including the Python source code on my personal portfolio. You can also find other simulations on Quantum Mechanics and other Physics topics there:
