More than tutoring, videos, or generic AI. This is the method behind Physics Sensei.

Meet Your Sensei

Hi, I’m Raul Barrea, a physics professor, lifelong learner, and black belt in karate.

I was not always good at physics. I struggled when I studied the way most students do, memorizing formulas, hoping things would click, and relying on explanation after explanation. It did not work.

Everything changed when I stopped treating physics like something to cram and started treating it like something to train. Structure. Repetition. Feedback. That shift became Physics Sensei.

Why students train with me

30+ years teaching college physics
PhD in physics
Black belt in karate
Creator of the Physics Sensei method
Focused on clarity, correction, and performance, not homework completion

How Physics Sensei was born

Karate taught me something school did not: you do not rise to the level of your goals, you fall to the level of your training. Repetition. Feedback. A coach.

That is how athletes improve, and it is how physics students improve too.

I saw the same thing in physics. Many students were not failing because they were incapable. They were failing because they had no real way to train.

So I built Physics Sensei as a place to train, not cram. Small wins. Daily rhythm. Clear correction. A coach in your corner.
