GitHub Exposé
A few repositories that show how I combine mathematical modeling, programming, and modern LLM-assisted research workflows.
Series Dash
Repository: Calvin1127XD/series-dash
An interactive Calc II teaching game that gamifies series-test practice and helps students visually decide which convergence test fits each series.
DiffuseDomainHelmholtz
Repository: Calvin1127XD/DiffuseDomainHelmholtz
A MATLAB package for cell-centered multigrid solvers of Helmholtz-type PDEs, including diffuse-domain/interface formulations in 1D and 2D with signed-distance/eikonal geometry handling.
CatFourierEmailSignature
Repository: Calvin1127XD/CatFourierEmailSignature
A playful signal-processing project: extract contours from an image, represent them with Fourier components, and produce an animated cat-style signature effect.
Benford_Testing
Repository: Calvin1127XD/Benford_Testing
A scientific-popularization project that demonstrates Benford's law on real datasets (including PDF-extracted values and election-style datasets), with visualization and testing scripts for exploratory analysis.
