I don't teach equations. I teach why the world obeys them.
13 years teaching physics across Grades 9–12 — mechanics, fields, and modern physics, taught as a way of thinking rather than a formula sheet. Demos first, models second, and never an answer without its units.

The Observer
Physics is a way of seeing, not a sheet of formulas.
I was the kid who took the ceiling fan apart to see why it slowed down. By Grade 10 I'd blown two fuses and read every popular-science book the library had — but nobody could tell me why any of it actually worked. So I became the teacher I'd wanted: one who treats a fifteen-year-old's 'but why?' as the most important question in the room.
Thirteen years on, I still teach for that kid, and just as hard for the one who's convinced they're 'bad at physics.' They're not — they've just been handed formulas before pictures. Intuition first, a clear mental model, then the mathematics that makes it precise. Never the reverse.
If your school wants physics taught as reasoning, not memorising, I'd love to talk.

The method
Every lesson swings like a pendulum
A good physics class is an experiment with a shape. You open with a question — a demo that shouldn't work but does — let the puzzle build, reach the turn where the equation and the world finally line up, then make them predict the next case on their own. Understanding isn't recall; it's the power to predict something you've never seen.
Open with a demo — a paradox, something that shouldn't work but does.
Build the model: the simplest picture that predicts what we saw.
The turn — where the equation and the world line up.
Verify by prediction. If they can call the next case, they own it.

Rajagiri Public School, Kochi
Lead a 6-teacher department; built the school's inquiry-lab program from scratch. Board physics distinctions rose from 38% to 74% of the cohort, with nine national-olympiad medallists.
2012 — 2016
Senior Physics Faculty
Choice School, Kochi
Grades 9–12 mechanics and modern physics; coached the Science Olympiad squad to three state podiums; started the low-cost demo-cart now used across the school.
2008 — 2012
Physics Teacher
Bhavan's Vidya Mandir, Kochi
Grades 9–10; built the hands-on lab-first program that turned 'I'm bad at physics' students into a cohort with the school's best practical scores.

Things I keep writing down

Nobody is actually bad at physics
Only students handed formulas before pictures. The intuition-first sequence I use to rebuild confidence.

Units are a lie detector, not bookkeeping
Teach dimensional analysis as a habit and careless answers vanish before they're written.

In their words
What the room says
"
Sir made me predict what the pendulum would do before we measured it. I was right, and physics was never scary again.

My daughter went from dreading physics to topping the olympiad screening. I still don't fully believe it.
