The Count

“Is counting the same as knowing?”

Look

Ten stepping stones cross a small patch of floor.

Try

Count the stones. Then look around.

Notice

Try the experiment first. Then this will fill in.

What keeps this room working?

The counted pieces really belong to a larger space.

What would break this room?

If counting the visible pieces meant you understood the whole hall.

Child-sized version

For grown-upsShow me the math

Ten stones are countable. The hall around them is not made of stones. A finite sample can be exactly right and still not be the space it was drawn from.

Discrete versus continuous
Stones come one at a time. The floor between them does not.
Sample
A finite handful taken from a larger space.
Dimension
A line of stones has one direction. The hall has more.
