The things of this world can not be known without the knowledge of mathematics.
Hermann Broch (1886-1951)
Mathematics is a kind of desperate act of the human spirit … in and of itself it we must not, of course, but it’s kind of honesty island.
Eugene Wigner (1902-1995)
The language of mathematics is effective unreasonably in the natural sciences […] a wonderful gift which we neither understand nor deserve.
Antonio Ambrosetti (1944-)
Even in mathematics it takes place a gradual development of knowledge that takes research to make strides. But there is always some results that escapes us and that will be proven in the future probably.
