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.
MDCalc is a source for medical equations, algorithms, scores, and guidelines. It offers a library of calculators, including the Cockcroft-Gault creatinine clearance equation, a weight-based levothyroxine dose calculator, CKD-EPI GFR equations, mean arterial pressure, and the SpO₂/FiO₂ ratio. Tools can be browsed by specialty and filtered by calculation purpose.
Luna Multiplayer is a multiplayer mod for Kerbal Space Program. It provides servers, time synchronization over NTP, reliable UDP messaging, interpolation for vessels, NAT punchthrough, and shared career and science mode resources among players. Servers are listed within the mod, and server hosting is offered through a partner.
A blog by Matthen presenting maths and science animations, including simulations and visualizations such as waves, rolling ellipses, Borromean rings and conic sections. Some posts link to code and interactive visualizations.
Phoenix RC is an educational resource for documentaries, courses, books, reference material, or self-learning.
Half Cat Rocketry is an X account with 730 posts describing itself as lowering the barrier to entry into amateur liquid rocket engines. The account links to HalfCatRocketry.com and was joined in July 2021.
PlanetMath is a virtual community aiming to make mathematical knowledge more accessible. Its main feature is a mathematics encyclopedia with entries written and reviewed by members, contributed under the Creative Commons By/Share-Alike License and written in LaTeX.
