Doc Brown's School Science Revision Notes and Quizzes is a science revision website that began in 2000 as a chemistry site and has since expanded. It offers revision notes and quizzes for biology, chemistry and physics at lower secondary, GCSE, IGCSE and advanced level, keyed to UK exam boards including AQA, Edexcel, OCR, WJEC and CCEA.
Wokwi is an IoT and embedded system simulator for ESP32, STM32, Arduino, Raspberry Pi Pico, displays, sensors, motors and WiFi, run online in the browser. It also offers options for VS Code, CI and JetBrains, plus a classroom offering used by universities and organizations.
OpenVSP is an educational resource for documentaries, courses, books, reference material, or self-learning.
Physics Forums is an online community of scientists, mathematicians, engineers and students. It hosts discussions across physics, math and engineering, with members able to post threads and replies. The site offers guidance on homework help with a required posting structure and lists subscription perks for gold members.
NumberFields@home is a research project that uses Internet-connected computers to do research in number theory, with participants downloading and running a free program. It searches for fields with special properties, with the primary application in algebraic number theory. It is based at the school of mathematics at Arizona State University and uses BOINC.
Corca is a collaborative math editor. It lets users type mathematical expressions without syntax or coding, with input behaving like search. Multiple people can work on math together in real time, and equations export to LaTeX for copying or document download.
A three-part curriculum aimed to help beginners self-study mathematics, covering core undergraduate subjects, electives, and possible study tracks. It assumes a modest background, mostly high school mathematics, and emphasizes solving exercises and problems.
