Hello! Im working as a math teacher on an upper secondary school sweden. As a last project for the students into programming I´m giving out a exercise where they should plot the roots of first, second and third order polynomials with integer coefficients (in a given interval). Hopefully resulting in some cool pictures of the complex plane. The best picture when will be printed on a A1 paper and hung on the wall in the classroom. However! I would also like to have a nice qoute along with the image. Which is the purpose of this thread. :) The qoute should peferably adress the questions 'what is math?' or 'what is a mathematician doing?'. Something along the lines of Erdös: "A mathematician is a machine which turns coffee into theorems" but more inspiring! I know that Grothendieck has written about this in his personal but published notes. But since I can't understand french I have a hard time finding qoutes thats suits. Do you guys have any suggestions? I´m very thankful for any help.
