Atomic is an educational resource for learning science, history, language, geography, or general knowledge.
Seeing Theory is an archived site offering a visual introduction to probability and statistics through interactive visualizations. It covers six chapters: basic probability, compound probability, probability distributions, frequentist inference, Bayesian inference and regression analysis. It was created by Daniel Kunin while an undergraduate at Brown University.
PassMedicine provides free UCAT revision with over 3,000 practice questions covering Verbal Reasoning, Quantitative Reasoning, Decision Making and Situational Judgement. The interface is designed to mirror the real exam, and users can compare their scores with others and discuss individual questions. A six-month subscription option is listed as free.
Horizon EDA is a free and open source electronic design automation package for printed circuit board design. It allows users to maintain and share a pool of parts, draw schematics, and design, 3D-preview and export PCB layouts for manufacturing. It runs on Linux and Windows.
Evan Chen's homepage collects course notes, olympiad materials, writings and a CV. The site states that Evan completed a number theory PhD at MIT and coaches math olympiads, and it links to handouts, past problems and solutions for high school students.
Algebrica is a free, open, and distributed mathematical knowledge base with content openly distributed on GitHub under the CC BY-NC 4.0 license. It offers publications in print and digital formats and accepts community contributions through a supervised review process.
A site that serves the version 5 KiCad libraries, providing schematic symbol libraries, PCB footprint libraries and 3D model data. The archived libraries are described as old, out-of-date and no longer maintained, with newer versions available from the KiCad website and GitLab. Users can clone the libraries with Git or SVN to receive updates.
