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.

IVYJUNE

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.
