Feynman – Don’t lecture and Feynman Technique — from donaldclarkplanb.blogspot.com by Donald Clark

Excerpt from the Feynman Technique section

  1. Write down everything you think you know about the topic from the top of your head
  2. Teach it to someone much younger
  3. Identify the gaps and fill them out
  4. Simplify, clarify and use analogies

Learning this way is iterative, as you must go back to sources to fill in any gaps uncovered by your attempts to recall what you think you know. The act of writing, teaching, simplification and analogising, is a form of retrieval practice that increases understanding and retention.

The Feynman Technique Can Help You Remember Everything You Read — from medium.com by Eva Keiffenheim
How to use this simple principle for you.


Social climber Dale Carnegie used to say knowledge isn’t power until it’s applied. And to apply what you read, you must first remember what you learned.

Nobel Prize-winning physicist Richard Feynman (1918–1988) was an expert for remembering what he learned.

Most people confuse consumption with learning. They think reading, watching, or hearing information will make the information stick with them.

Unless you’ve got a photographic memory, no idea could be further from the truth.

Teaching is the most effective way to embed information in your mind. Plus, it’s an easy way to check whether you’ve remembered what you read. Because before you teach, you have to take several steps: filter relevant information, organize this information, and articulate them using your own vocabulary.
