Field notes
The site organizes its material as manipulable experiments rather than static explanations: users alter orbital shape, move through lunar phases, model an exoplanet transit, or calculate telescope viewing parameters. Its FAQ distinguishes standard equations from simplified educational models and notes that planet positions are not a live sky map. The homepage also presents an SVG download option for lessons and links to related interactive tools for chemistry, geometry, biology, and coding.
