Interactive long-form articles explaining GPS, mechanical watches, naval architecture, and physics — built with hand-coded simulations you can manipulate in real time.
Each article on this personal blog is a standalone technical deep dive rendered with custom interactive diagrams you can drag, adjust, and manipulate in real time. Topics include GPS signal triangulation, how mechanical watches keep time, orbital mechanics, camera optics, and the physics of sound — all explained from first principles.
Why it is useful
These are not blog posts — they are interactive textbooks produced by a single person, each taking months to build. The GPS article alone contains dozens of live simulations that let you move satellites, adjust receiver positions, and watch timing errors resolve in real time. There is genuinely nothing else on the internet at this level of explanatory craft.
