ChemSpider is an educational resource for documentaries, courses, books, reference material, or self-learning.
Red Blob Games publishes interactive visual explanations of math and algorithms, using examples from computer games and other projects. Topics include pathfinding, map generation from noise, hexagonal grids, Voronoi diagrams, graph theory and 2D visibility. Articles are free, with no signup and no ads, aimed mainly at independent, student and hobbyist software developers. The site also hosts demos such as map generators.
MadAsMaths is a mathematics resources site offering free materials for students and teachers. It provides mathematical booklets classified by topic with questions and full solutions, practice papers with solutions, and Project Maths PowerPoint presentations. The site is static with no further updates and its contact form deactivated.
SmartCockpit is a free online aviation library offering aircraft-type specific quizzes and information on flight operations and safety. Since 2000 it has aimed to serve professional pilots worldwide, covering topics such as human factors and type rating preparation.
SeligSIM is a free RC flight simulator for Windows that also runs on Mac and Linux. It offers over 140 airplanes and 35 flying sites, with aerodynamics and physics modeling. It has been in continuous development since 2003 and was originally known as FS One.
Physclips is a multimedia education project offering physics animations and video film clips for introductory physics at different levels. Its current topics include kinematics, mechanics, special relativity, waves, sound, electricity and magnetism. Resources may be freely used by teachers, and students may use the whole package, including interactive tutorials and support pages.
Spider ID is an online community of amateur and professional spider enthusiasts. Registered members submit spider pictures and educational information and help identify spiders. The site displays counts of pictures, species and members, and lists popular spiders and spiders by location.
