We cannot define anything precisely! If we attempt to we get into that paralysis of thought that comes to philosophers who sit opposite each other one saying to the other ‘You don’t know what you are talking about!’ The second one says ‘What do you mean by know? What do you mean by talking? What do you mean by you?’ and so on. ~ Richard Feynman 1918 to 1988
The ultimate truths of mathematics then cannot be established by any experimental proof that the deductions from them are true; since the supposed experimental proof takes them for granted. ~ Herbert Spencer 1885 – 1977 - Philospher

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
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
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
God created two acts of folly. First He created the Universe in a Big Bang. Second He was negligent enough to leave behind evidence for this act in the form of microwave radiation. - Paul Erdős 1913 to 1996 Mathematician
Chemistry is necessarily an experimental science: its conclusions are drawn from data and its principles supported by evidence from facts. ~ Michael Faraday - 1791 to 1867
Everything that human beings or living animals do is done by protein molecules. And therefore the kind of proteins that one has and therefore the ability one has is determined by the genes that one has. ~ Har Gobind Khorana 1922 – 2011 - Molecular Biologist
All increasing or dominant species (and it is from these that new species arise) vary considerably in all their parts organs and faculties in every generation. ~ Alfred Russel Wallace 1823 to 1913 - Zoologist Evolutionary Biologist
