Visuals

A place to house striking visual demonstrations of real physics and engineering — CFD simulations, flow visualizations, diagrams, photos, and video that make an effect visible in a way words alone don’t. Each entry carries the original source (embedded where possible, saved as a static image as a fallback) alongside a plain-language explanation of what it’s actually showing. As with Field Notes, not every entry connects to Pressure-Based Theory directly — some are just real physics worth seeing clearly. Where a genuine connection to PBT exists, it’s called out explicitly rather than implied. See the Catalog for how the underlying physics in each entry is classified.
