What exactly is mathematics? Many have tried but nobody has really succeeded in defining mathematics; it is always something else. Roughly speaking people know that it deals with numbers figures with relations operations and that its formal procedures involving axioms proofs lemmas theorems have not changed since the time of Archimedes. ~ Stan Ulam 1909 – 1984 - Mathematician

No two electrons in the same state? That is why atoms are so unnecessarily big and why metal and stone are so bulky. (Explaining that atoms are as large as they are because of Wolfgang Pauli’s Principle.) ~ Paul Ehrenfest 1880 – 1933
The literary convention that numbers less than 10 should be given in words is often highly unsuitable in mathematics… The excessive use of the word forms is regrettably spreading at the present time. ~ J.E. Littlewood 1885 – 1977 - Mathematician
The country which is in advance of the rest of the world in chemistry will also be foremost in wealth and in general prosperity. ~ William Ramsay - 1852 to 1916
An experiment is a question which science poses to Nature and a measurement is the recording of Nature’s answer. - Max Planck 1858 to 1947 Theoretical Physicist
Trial by combat of wits in disputations has no attraction for the seeker after truth; to him the appeal to experiment is the last and only test of the merit of an opinion conjecture or hypotheses. ~ Joseph Mellor - 1869 to 1938
The invention of logarithms came to the world as a bolt from the blue. No previous work had led up to it… It stands isolated breaking in upon human thought abruptly without borrowing from the work of other intellects or following known lines of mathematical thought. ~ John Moulton 1844 – 1921 - Mathematician
There may be babblers wholly ignorant of mathematics who dare to condemn my hypothesis upon the authority of some part of the Bible twisted to suit their purpose. I value them not and scorn their unfounded judgment. ~ Nicolaus Copernicus 1473 – 1543 Mathematician and Astronomer
