Every page in this book asks the same four things, in the same order: name the concept, explain it as if to somebody who has never heard of it, mark the exact point where that explanation ran out of words, then try again, shorter. The third box is the one that does the work. It is easy to reread a chapter fluently and mistake the fluency for understanding; it is much harder to write a plain explanation of the same chapter and notice exactly where it stops.
One hundred twenty pages hold that shape. A further run of plain ruled pages sits behind them for whatever does not fit inside four boxes: a diagram, a worked example, a question for someone who actually knows.
It does not grade the explanation. It does not know the subject either. It only keeps asking until the third box runs out of room, and what goes in that gap is the reader's problem, not the page's.

In every book
The same six pages open every book: your details, who to call, the signs to point at when you have no shared language, and the map. They sit at the front because the moment you need them is not the moment to be flicking through.
- This book belongs to
- One page for your name and number, so a book that goes missing can come back.
- My details
- Blood group, allergies, who to call. Written once, carried everywhere.
- Emergency numbers
- Forty countries, taken from Wikidata property P2852 (CC0), agreed across two sources, every row carrying its QID. Numbers change and a book does not — verify locally on arrival.
- Point at this
- A pictogram grid captioned in English above and Indonesian below, for when there is no shared language.
- World map
- Natural Earth 110m, public domain, equirectangular, with UTC hour meridians computed from the projection rather than from a timezone database. For orientation and for pointing at, not a navigation chart.
- Conversion tables
- Computed from definitions — 25.4 mm to the inch — and not copied from anywhere, so every row can be checked by anyone holding the book.
- Pen test leaf
- The last page, printed for it on purpose. Every notebook is used this way; printing it deliberately is cheaper than losing the last leaf to it by accident.

Questions
What are the four boxes on each page?
A line for the concept, a box to explain it as if to a beginner, a box for where the explanation broke down, and a box to say it again, shorter.
How big is it?
A5, 148 x 210 mm, 140 pages, 8.01 mm across the spine.
Is it ruled or blank?
Neither. Each page is divided into the four boxes and nothing else; the ruled pages at the back are separate.
Is it dated?
No.
Does it teach the Feynman technique?
No. It gives the technique room to happen on paper. Learning it is still the reader's work.
What youthful philosophers and experimentalists we are!
