But though the professed aim of all scientific work is to unravel the secrets of nature it has another effect not less valuable on the mind of the worker. It leaves him in possession of methods which nothing but scientific work could have led him to invent. ~ James Clerk Maxwell 1831 to 1879
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 Astronomer Mathematician

Outstanding examples of genius – a Mozart a Shakespeare or a Carl Friedrich Gauss – are markers on the path along which our species appears destined to tread. - Fred Hoyle 1915 to 2001 Astrophysicist
Falsity in intellectual action is intellectual immorality. - Thomas Chrowder Chamberlin 1843 to 1928 Geologist
The time however has arrived when biology must like the other sciences make a fresh start in a purely speculative direction free from all entanglement with medical or any other art. ~ Auguste Compte 1798 to 1857 - Philosopher of Science
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 Chemist
I see some parallels between the shifts of fashion in mathematics and in music. In music the popular new styles of jazz and rock became fashionable a little earlier than the new mathematical styles of chaos and complexity theory. Jazz and rock were long despised by classical musicians but have emerged as art-forms more accessible than classical music to a wide section of the public. Jazz and rock are no longer to be despised as passing fads. Neither are chaos and complexity theory. But still classical music and classical mathematics are not dead. Mozart lives and so does Euler. When the wheel of fashion turns once more quantum mechanics and hard analysis will once again be in style. ~ Freeman Dyson b. 1923 - Mathematician and Physicist
This is an era of specialists each of whom sees his own problem and is unaware of or intolerant of the larger frame into which it fits. ~ Rachel Carson 1907 to 1964 - Marine Biologist
