Generating Hypotheses
Why do you think Leonardo wrote backwards.
Post these hypotheses where they are visible

Feel free to come up with ideas for experiments
to test some of these hypotheses.

Further Thought
Not all languages are normally written from left
to right. Hebrew is normally written from right to
left. Traditional Japanese and Chinese are
written from top to bottom starting at the right
side of the page. Do you know of any other
languages that are not written left to right?
If you were given the task of inventing an
entirely new written language, which direction
would you want it to be written in?
Why?
