To have peace with this peculiar life; to accept what we do not understand; to wait calmly for what awaits us, you have to be wiser than I am.

I came to the ... open gate of mathematics. From here, well-trodden paths lead in every direction, and since then I have often spent time there. Sometimes I think ... I have trodden all the paths ... and then I suddenly discover a new path and experience fresh delights.

What I give form to in daylight is only one per cent of what I have seen in darkness.

It has always irked me as improper that there are still so many people for whom the sky is no more than a mass of random points of light. I do not see why we should recognize a house, a tree, or a flower here below and not, for example, the red Arcturus up there in the heavens as it hangs from its constellation Bootes, like a basket hanging from a balloon.

I never got a pass mark in math ... Just imagine - mathematicians now use my prints to illustrate their books.

It is human nature to want to exchange ideas, and I believe that, at bottom, every artist wants no more than to tell the world what he has to say.

Only those who attempt the absurd will achieve the impossible. I think it's in my basement... let me go upstairs and check.
