For a favorite sci-fi artifact worth bringing our world, I propose “treeing” from Binti, as used in Binti:
As a fun activity to bond with your female friends - “Yet they were girls who knew what I meant when I spoke of “treeing.” We sat in my room (because, having so few travel items, mine was the emptiest) and challenged each other to look out at the stars and [do treeing]”
As a practice to calm oneself or reach a meditative state - “Before the realization hit me, I knew to drop into meditation, treeing out of desperation. I held myself in there for a moment, equations flying through my mind, like wind and sand. Around me, I heard movement and, still treeing, I saw that the soldiers were leaving the room.”
What is “treeing”?
Binti: “Imagine the most complex equation and then split it in half and then in half again and again. When you do math fractals long enough, you kick yourself into treeing just enough to get lost in the shallows of the mathematical sea.”
In this passage I saw tree fractals with a Hausdorff dimension of 2. Such as Pythagoras trees or H trees or Hilbert curves. At their higher orders, each of these fractals fill space, but they can be iteratively reduced (split in half), again and again, each time simplifying them by the same rules that built them.
