Who we are
About TRYE.org
TRYE.org brings together the subjects and practical skills that shape science, engineering and modern technology. Our goal is to make useful learning resources easier to discover, understand and apply—whether someone is studying a first principle or exploring a more advanced technical topic.
Practical learning
Connect concepts with calculations, visual demonstrations, coding exercises and project ideas that help learners build confidence through practice.
Who we serve
Support students, teachers, engineers, researchers, developers and lifelong learners at different stages of their education and careers.

STEM Tools, Calculators & Project Directory
The directory below outlines the tools and learning projects we plan to develop across mathematics, engineering, science, programming and education. These entries describe our roadmap; they are not a claim that every tool is already available.
Availability notice
Every tool is treated as planned unless its matching PHP page exists in the same directory as this About Us page. Existing pages are linked; pages that have not yet been created are shown as planned and are not clickable. A file's presence only confirms that the page exists, not that every feature has been fully tested.

Our vision for accessible STEM learning
We envision TRYE.org as a useful online destination where learners can move from curiosity to understanding and from theory to practice. Over time, the platform aims to expand its educational articles, engineering references, calculators, interactive simulations, programming utilities and responsible AI-assisted learning features.
Our roadmap will evolve based on usefulness, accuracy, accessibility and feedback. Tools involving engineering, science or academic calculations should clearly explain their assumptions and limitations so visitors can use results thoughtfully and verify important work with authoritative references or qualified professionals.
