What is Bartosz Ciechanowski?
Bartosz Ciechanowski writes long, hand-built articles that explain how everyday things and physics work. Each one is packed with interactive 3D demos you can drag, rotate and adjust with sliders, so you see the idea move instead of just reading about it.
Topics include the Moon, airfoils, bicycles, sound, mechanical watches, GPS, curves and surfaces, internal combustion engines, cameras and lenses, gears and color spaces. New articles come out slowly because each one takes a long time to make. The articles are free to read, and a Patreon membership supports the work and unlocks extra posts.
