Technical writing on science and engineering.

These articles explore topics I find interesting. My current focus is on data-driven science and engineering. I combine explanations with interactive explorations.

Learning a Basis from Heartbeats

Learn a basis from thousands of recorded heartbeats with the SVD, then use it to compress beats and to flag the ones that do not fit.

Compression Playground

Load a photograph, pick a basis, and throw coefficients away to see what survives.
