Who would set a limit to the mind of man? Who would dare assert that we know all there is to be known?
We must say that there are as many squares as there are numbers.

If I were again beginning my studies, I would follow the advice of Plato and start with mathematics.
I give infinite thanks to God, who has been pleased to make me the first observer of marvelous things.
