I asked this question to my children. It turned out that they "miss" a number of incomprehensible terms, and often they contain history, life.
I wanted to make up for this injustice without touching the author's text, which I have loved since childhood. I came up with the idea of making a layout-roll call of the times, where questions were asked by the hand of a modern child, and in the margins with footnotes - answers with small illustrations in a sketchy manner.
Screenshots of the layout layout and small illustrations are given below.
