Lamp waiting

Look

The last room is nearly empty. A door stands open. Light comes through it.

Try

Walk to the door.

Notice

Try the experiment first. Then this will fill in.

What keeps this room working?

The atlas stays incomplete. There is always an outside.

An atlas is a collection of local charts. For the Hopf fibration no single chart covers everything, so the collection stays open. The house is a rigorous example, not a claim about what the world is made of.

Atlas: A collection of local charts. None of them is the whole.
Open cover: Overlapping patches that cover a space without one patch doing it all.
No universal chart: No one map can be promoted into the map of everything.
