The Feynman Technique & Cognitive Load

True learning occurs when you can explain a difficult concept in simple terms, identifying your own knowledge gaps along the way.

This process reduces intrinsic cognitive load, allowing your working memory to function at maximum efficiency.

By organizing your notes effectively, you build a "second brain" that accelerates your intellectual growth over time.
