Do not worry about your difficulties in Mathematics. I can assure you mine are still greater.
I went off to college planning to major in math or philosophy - of course, both those ideas are really the same idea.
Mathematics is the queen of the sciences.
Carl Friedrich Gauss, from Sartorius von Waltershausen, "Gauss zum Gedachtniss" (1856)
Mathematics, rightly viewed, possesses not only truth, but supreme beauty - a beauty cold and austere, like that of sculpture.
I have hardly ever known a mathematician who was capable of reasoning.
Plato, from The Republic
As far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality.
Albert Einstein, "Geometry and Experience", January 27, (1921)
We used to think that if we knew one, we knew two, because one and one are two. We are finding that we must learn a great deal more about 'and'.
Sir Arthur Eddington, The Harvest of a Quiet Eye (A. L. Mackay), 1977
Mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true.
Bertrand Russell, Mysticism and Logic (1917) ch. 4
