• <Tragedy of Faust by Johann Wolfgang von Goethe> "Unlock'd the spirit - world doth lie, thy sense is shut, thy heart is dead! Up scholar, lave, with courage high, thine earthly breast in the morning - red!"

  • <Eloge de M. Euler par le Marquis de Condorcet> "Mathematics is the science that yields the best opportunity to observe the working of the mind. Its study is the best training of our abilities as it develops the power and the precision of our thinking. Mathematics is valuable on account of the number and variety of its applications. And it is equally valuable in another respect: By cultivating it, we acquire the habit of a method of reasoning which can be applied afterwards to the study of any subject and can guide us in life's great and little problems."

  • <Karlin, Samuel (11th R. A. Fisher Memorial Lecture, Royal Society 20, April 1983)> "The purpose of models is not to fit the data but to sharpen the questions."

  • <Eigen, Manfred> "A theory has only the alternative of being right or wrong. A model has a third possibility: it may be right, but irrelevant."

  • <Russell, Bertrand> "Although this may seem a paradox, all exact science is dominated by the idea of approximation."
