Find some pictures of amoebas and other organisms that live in a
virtually planar environment. What kinds of sense impressions do they
receive that are different from ours? What would correspond to an eye for
an amoeba?
In what ways is the amoeba world not really two-dimensional? What would
happen if we picked an amoeba up and held it vertical?
Would an amoeba have any sense of gravity? How would it be diffferent
from our notions of weight or mass?
We speak naturally of height, a distinguished direction. What would it
be like to live as an amoeba? Would there be anything in its world
corresponding to height?

Study the cover of the first edition of "Flatland" and not the numbers
hidden in he cloud at the top. How many dimensions is the author inviting

There are two quotations on the front page, both by the same author.
Can you find out where they came from?

Make up a "dimensional story", where someone becomes conscious of
dimensional limitation and wishes for more dimensional freedom.
Collect some data from family members, such as the hat size, or
distance from the elbow to the end of the fingers, or the span measured

How does an oculist view a patient? What numbers does a cardiologist care about?
Given two views of a tool or a building, under what circumstances can
