Yes — completely and permanently free. Every article, simulation, and practice problem we publish will remain free forever. We believe quality physics education should not depend on your income or location.

Every article is written by a working physicist. Our core team includes Dr. James Carter (mechanics), Dr. Sarah Kim (thermodynamics), Dr. Elena Vasquez (waves), and Dr. Marcus Webb (modern physics and gravity). All content is reviewed for scientific accuracy before publishing.

Our guides are written to serve students from GCSE/high school through to first-year university level. The approach — intuition before equations — makes the content accessible to curious beginners while being rigorous enough for students preparing for university-level physics.

Join the waitlist from the homepage or any “Get Early Access” button. Early access members will be the first to receive notifications when simulations, practice problems, and new modules go live. No payment is ever required.

Please report it immediately using the contact form above and select “Report an error.” We treat accuracy as paramount — errors are reviewed and corrected as a priority, usually the same day. We genuinely appreciate every report.

Absolutely. Reader suggestions have directly led to several of our published guides. Use the contact form and select “Topic suggestion.” The more specific you are — a concept, a common misconception, a type of problem — the more useful your suggestion will be.

Yes. Teachers and tutors are welcome to share links to our articles with their students. If you’d like to use content in course materials, get in touch via the form and we’ll discuss appropriate arrangements.

We’re selectively looking for physicists and educators who share our commitment to depth and clarity. If you’d like to write, review, or help develop simulations, send us a message via the form above. Include a short note about your background and what you’d like to contribute.
