stemformulas.com is a website focused on STEM formula lookup, aiming to become a centralized database for finding formulas in science, technology, engineering, and mathematics. According to the site’s description, it was created by several engineering students who were dissatisfied with the online formula search experience, so the product focuses on “finding formulas quickly” and making them easy to copy and share. It is worth noting that this is not a traditional online course platform, nor does it offer structured courses, video lessons, homework assessment, or a certificate system.
The site’s core functionality revolves around formula search: after the page loads, the search box is automatically focused so users can start typing immediately; the “/” key can be used to open search from any page; and LaTeX on formula pages can be clicked to copy, which is very practical for users writing papers, doing assignments, or taking Markdown/LaTeX notes. Formula pages also generate preview images when shared on social media, and mobile-friendliness is another design point the site explicitly emphasizes.
The main content does not mention any fees, subscriptions, or paid services. The site states that it is open source on GitHub, uses the Hugo static site framework and the Congo theme, and is hosted via GitHub Pages with deployment through GitHub Actions. Users can submit formulas through the suggestion page or directly submit Pull Requests to the GitHub repository.
Its strengths are clear positioning, a lightweight and fast experience, good support for LaTeX users, and an open-source mechanism that helps the community contribute content. Its weaknesses are also obvious: the site acknowledges that it still has a long way to go before becoming a complete formula database; there is no visible information about formula coverage, review standards, or update frequency; and it does not provide course explanations, learning paths, practice problems, teacher Q&A, or certification.
It is suitable for STEM students, engineering learners, teachers, research writers, and users who need to quickly copy formulas in LaTeX. If the goal is to systematically study mathematics, physics, or engineering courses, it should only be used as an auxiliary lookup tool rather than a replacement for textbooks, courses, or computational software.
The crawled content does not provide information about access from mainland China. Since it is hosted on GitHub Pages, actual access may be affected by the network environment, but this alone is not enough to determine whether it is directly accessible or restricted, so its status is marked as unknown.
