About
Understanding is something you build, not something you’re told.
Most explanations are written to be read. Ours are built to be tested. You make a prediction, run the model and find out where your intuition breaks. Then you put it back together in your own words.
“What I cannot create, I do not understand.”
Why Feynman?
Richard Feynman was famous for refusing to accept an explanation he couldn’t rebuild from scratch. His test was simple: if you can’t explain it plainly, try it on a simple case, and if you can’t make it work, you don’t understand it yet.
That’s the loop every quest follows: predict, experiment, explain, apply. We’re not affiliated with Feynman or his estate. We named the school after the way he thought.
The mark
The f is an integral sign: small steps, added up, become something whole. The gold s is the curve of learning itself, and the orbit is the loop you keep coming back around, a little further each time.
Founder
Vikash Srivastava
Vikash has taught since school and college. He founded AlmaBetter, which ran cohort courses in AI/ML and software engineering: over 1M free learners in its first three years, and more than 35K enrolled.
He spent about ten years in industry ML and large-scale software. At AlmaBetter he built hand-made interactive labs that unstuck learners where abstraction froze them, in probability, linear algebra and ML. They worked, but each one took weeks to build.
Feynman School builds that kind of lab for any question, in minutes.
What we believe about learning
Route before response
A good teacher doesn’t answer everything at once. We plan a short route of ideas, then teach the next useful step.
One shared model
Each quest keeps one scenario, with the same quantities and assumptions, so the idea builds instead of resetting.
Interaction carries the idea
Controls and diagrams have to reveal something about the model. Nothing is there just for decoration.
Honest about limits
Every model says what it simplifies and where it stops being true. We never claim you’ve mastered something.
Come and break something.
The fastest way to see what we mean is to try a lab.
