The Two Windows
“Can two views share something real?”
Ivy and June stand in different rooms and look outside.
Try
Bring the two windows together.
What Ivy sees
- a tree
- a pond
- half of a bridge
What June sees
- half of a bridge
- a garden
- a birdhouse
Notice
Try the experiment first. Then this will fill in.
Different views
They do not need the same view to share something real.
Where they meet
Shared truth can live in the overlap.
And still
Neither window has to replace the other.
Child-sized version
“We can see different things and still meet somewhere real.”
For grown-upsShow me the math
Two local charts overlap. On the overlap they must agree. Neither chart is the atlas.
- Local chart
- One window's view.
- Overlap
- The part both windows show.
- Compatibility
- On the overlap, the two views agree.
