A concept list and 60 concept pages that walk the four steps of the Feynman technique, with a spaced review log so it stays learned. 86 hyperlinked pages, undated.
Reading a thing twice feels like knowing it. Explaining it on a blank page shows you where you do not. Each concept page makes you write the simple version, mark the gaps, go back to the source and try again.
A filled guide sits at the front, one worked page per section, so you see each page in use before you write in it. It sits well beside the Zettelkasten and Commonplace Book systems.
The concept list, two concept pages, the review log and notes. Tap a thumbnail to look closer.































































































Name it, explain it simply, find the gaps and go back to the source, then simplify it with an analogy and one line.



















Every concept you take on, numbered, with each row opening its own page.



















Day 1, day 3, week 1 and month 1: explain it again from memory and note what slipped.
