Bayes’ Theorem: The Probabilistic Thinking Tool Behind Better Decisions Last year I was building a customer churn model. I hadn’t internalized Bayes’ theorem at all, and the predictions were a disaster. After I finally worked through the math, something clicked. This formula is not just a textbook exercise. It’s a mental model. Bayes’ theorem answers […]
Nature Does Not Waste: Circular Economy, Doughnut Economics, and the Ecological Bottom Line There is no word for ‘waste’ in most natural systems. Water, carbon, nitrogen move through soil, plants and microbes; one organism’s effluent becomes another one’s meal. Industry, by contrast, runs on a ‘take, make, dispose’ one-way track. Years ago, while working on
Molecular Dynamics Simulations: A Computational Engine from Atomic Motion to Drug Design Molecular dynamics (MD) simulation sounds like a purely theoretical craft, but once you actually dive in, it feels intensely practical. You feed in an initial set of coordinates and velocities, define the force field that describes how atoms interact, and then integrate the
