Flatland、Section 15の要約
22のSection 15 · Part 2: Other Worlds “O brave new worlds, that have such people in them!” · sectionは6分で読めます
In Section 15, the narrator rejects his youngest grandson’s suggestion that cubing a number has a geometrical meaning, but a mysterious visitor appears and contradicts him. The visitor’s changing size confounds the narrator’s observations, and his request for a private conversation clears the room as the third Millennium begins.
