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

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

Are you really sure that a floor can't also be a ceiling?

Science and art sometimes can touch one another, like two pieces of the jigsaw puzzle which is our human life, and that contact may be made across the boderline between the two respective domains.
