Do you and I see alike?

"We do not know what we see, wee see what we know" Goethe

The optic nerve contains over 1 million fibers, compared to 50 000 in the auditory nerve.
Visualization offers a method of seeing the unseen.
The visual display of information enables us to see the story, to envision some cause-effect relationships, and possibly to remember it vividly.
Visualization can have a powerful complementary role in math :
:) support on illustration of essentially symbolic results
:) a possible way of resolving conflict between symbolic (correct) solution and (incorrect) intuitions
:) as a way to help us re-engage with and recover conceptual underpinnings which may be easily bypassed by formal solutions
