Physics is a way of seeing, not a sheet of formulas.

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.

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.

If your school wants physics taught as reasoning, not memorising, I'd love to talk.

The method

Every lesson swings like a <em>pendulum</em>

Arjun's view — Demos first — models second.

  1. Open with a demo — a paradox, something that shouldn't work but does.
  2. Build the model: the simplest picture that predicts what we saw.
  3. The turn — where the equation and the world line up.
  4. Verify by prediction. If they can call the next case, they own it.

In their words

What the <em>room</em> says

"

Sir made me predict what the pendulum would do before we measured it. I was right, and physics was never scary again.

Aditya Grade 12, 2025
"

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

Parent Grade 11 program
"

He rebuilt our physics results and our lab culture at once. The department is unrecognisable.
