Feynman technique to learn things

Any concept should be explainable to a child. If it is not, then the concept is not fully understood.


  1. Choose a concept to learn about
  2. Pretend to teach it to a child in plain language
  3. Identify gabs in the explanation and fill the gaps, repeat step 1
  4. Rewrite complex sections in simpler language

Note taking

Applied to note taking, the notes can be written like they are addressed to a child. By reading the notes (reviewing) the gaps in knowledge can be found. After filling in the gaps, the note can be changed until a concept is explained in a simple way with plain language.

Ask why

Think of questions a child might have. Why is a concept like that? This helps to test if a concept is fully understood.

Richard Feynman

"Feynman" technique is named after Richard Feynman. A Nobel Prize winning theoretical physicist.

These notes are unpolished collections of thoughts, unfinished ideas, and things I want to remember later. In the spirit of learning in public, I'm sharing them here. Have fun exploring, if you want!
