Ciechanow.ski is an extraordinary personal blog by Polish engineer Bartosz Ciechanowski, dedicated to interactive explanations of physical and technical phenomena. The site features a growing collection of in-depth articles exploring topics such as internal combustion engines, gears, watches, orbital mechanics, magnetism, and more — all illustrated with real-time WebGL-based animations and simulations.
What makes the site stand out is its commitment to learning by interaction. Readers don’t just passively read — they manipulate diagrams, change parameters, and explore how systems work in real time. The level of precision and pedagogical clarity is exceptional, rivaling academic textbooks while remaining fully accessible and visually engaging.
Although many articles are available in English, the site’s primary language is Polish. Regardless of language, the visuals speak universally and invite exploration by learners of all backgrounds.
🔗 ciechanow.ski is a brilliant example of how the open web can be used to share knowledge, curiosity, and technical insight — free of ads, tracking, or commercial noise.
