The sequel to the pyGOTM story. I pointed my Python ocean model at one real lake for twenty-two years and it failed in a way that was almost insulting. This is how I discovered the model was only half lake-aware, fixed the physics, and learned to live with an honest FAIL that is arguably more faithful than a PASS.

The honest story of pyGOTM — an open-source Python translation of GOTM that brings forty years of ocean turbulence physics into the language the next generation of scientists already uses. Ten weeks of failures, pivots, and one invented validation methodology.

A reflective look at what AI can and cannot replace in high-consequence engineering — and why the nuclear engineer doing safety analysis work is positioned for elevation, not obsolescence.

A first-person account of building htcie — a deterministic, audit-first correlation selection engine for single-phase convection heat transfer — and what I learned chasing correctness through primary sources.
