The title was suggested by a recent New Yorker poem.

(For Harlan Kane)
"Once Mr. Overbye identifies a story, he said, the work is
in putting it in terms people can understand. 'Metaphors
are very important to the way I write,' he said. The results
are vivid descriptions that surpass mere translation."
— Raillan Brooks in The New York Times on a Times
science writer, October 17, 2017. Also on that date —
"There is such a thing as a 4-set."
— Saying adapted from a 1962 young-adult novel.

"… Max Black, the Cornell philosopher, and others have pointed out
how 'perhaps every science must start with metaphor and end with
algebra, and perhaps without the metaphor there would never have
been any algebra' …."

Desiring the exhilarations of changes:
The motive for metaphor, shrinking from
The weight of primary noon,
The A B C of being,
The ruddy temper, the hammer
Of red and blue, the hard sound—
Steel against intimation—the sharp flash,
The vital, arrogant, fatal, dominant X.

not quite ready for solving anything but toy problems and
testing basic algorithms."

" 'Before I go somewhere for a story, I have a certain understanding of
what form it will take, and when I get there, it’s always far, far more
complicated,' says the journalist and poet Eliza Griswold, over lunch
in Gramercy Park. 'They begin with a neat little bow' — she pantomimes
tying it, her wide blue eyes growing wider — 'and then: kaboom.' ”
