“If physics feels hard,
it just means you didn’t have a good teacher.”
Hi! 👋
I’m Hassan Bagheri — a physics MSc and a teaching enthusiast. I started teaching in 1998, at every level of schooling, and for about a decade taught high-school physics continuously.
There’s also a hard truth: teaching, at least for me, was never particularly rewarding financially. So for years my main job has been software — a passion I first fell in love with in an “Introduction to Numerical Computing” course at university. I currently work as a programmer, right now on web applications. But if I score physics at 100, computers come in at 50 — and there is nothing else between them. 🤓
This site is, honestly, a way to return some of my time to that first love — physics.
International experience 🏆
Since 2009, I’ve had the honor of working with the International Young Physicists’ Tournament (IYPT), both as a coach and as a juror. If you’re unfamiliar with IYPT: it’s one of the most prestigious student physics competitions in the world — but nothing like fast-paced multiple-choice tests. In IYPT, students work on an open, real-world problem for months, run experiments, build theory, and finally take the stage to defend it verbally and field tough questions from the opposing team.
That experience deeply changed how I think about physics education — I learned that the most important thing in physics isn’t “knowing” but thinking. And that’s what I try to bring to every lesson, every problem, and every flashcard on this site.
My philosophy 🎨
Physics is like poetry. Physics problems are like paintings and poems — you just have to learn their language. 🖼️
I’m not going to turn you into a physicist. My goal is to make you love physics. If you leave this site and only one thing sticks — that physics can be beautiful — my job is done. The rest you’ll pursue on your own, driven by curiosity.
Something similar about programming: a programmer is someone who writes poetry in a different language. Learning a computer language is easier than learning a foreign one — but skill comes with practice and love. If you want to be a good programmer, you have to be the kind of person who sits down at the computer in the morning and then realizes wait, it’s night — I haven’t even had breakfast! ☕
Who is this site for? 🎯
- High-school students — if you’re studying grade 10/11/12 physics and want, alongside the textbook, a warmer narrative and living examples
- University-entrance-exam candidates — if you want to understand concepts deeply rather than memorize them, and practice problem-solving with step-by-step guidance
- Olympiad candidates (IYPT, IJSO, etc.) — articles and analyses aimed at students who want to work seriously
- Engineering and science undergraduates — a quick, clear review of the fundamentals
- Any physics enthusiast — even if you’re not a student, physics is a beautiful way to understand the world
What goes on this site? 📚
What’s here and what’s coming:
- ✅ Lessons from the high-school physics textbook — step by step, in a tone you won’t find in the book (chapters 1–5 of grade 10 are ready; grade 11 and 12 in progress)
- ✅ End-of-chapter problem solutions — step-by-step, with guidance and an answer checker
- ✅ Flashcards and games — review with points and challenges
- 🔜 Exam questions from past years — analyzed, not just answered
- 🔜 IYPT and IJSO articles — open problems, experiments, physics thinking
- 🔜 Videos and physics experiments — with full explanations
- 🔜 University introductory physics — for first-year undergraduates
- 🤔 Maybe… a corner of the site for programming — if I find the time. Because that too is a poetic language.
A promise 🤝
No question is “stupid” to me. If you didn’t understand something, it’s probably not your fault — it’s on whoever didn’t explain it well. Ask your question in the comments below any page, and I’ll get back to you as soon as possible. Even if you say “this text is confusing”, I’d love to hear it — so I can make it better.
Coming soon… 🤖
I’m working on something exciting: an AI assistant trained on my lessons and my teaching style, so you can ask your questions any time of the day or night and get quick answers — in my own voice and approach. Stay tuned! 🚀
