TODO: add relevant Feynman quotes/anecdotes here.
- "I first got the idea from this method from the Nobel prize winning physicist, Richard Feynman. In his autobiography, he describes himself struggling with a hard research paper. His solution was to go meticulously through the supporting material until he understood everything that was required to understand the hard idea." 
The technique (in its modern form) seems to have been created/popularized by Scott Young around August 2011.
