A theory is a supposition which we hope to be true a hypothesis is a supposition which we expect to be useful; fictions belong to the realm of art; if made to intrude elsewhere they become either make-believes or mistakes. - George Johnstone Stoney 1826 to 1911 Physicist
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

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
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
Simple laws can very well describe complex structures. The miracle is not the complexity of our world but the simplicity of the equations describing that complexity. ~ Sander Bais b. 1945 - Theoretical Physicist
Surely it is not knowledge but learning; not owning but earning; not being there but getting there; that gives us the greatest pleasure. ~ Carl Friedrich Gauss 1777 – 1855 - Mathematician and Physicist
Although the alternate ‘wax and wane’ cycles are the rule rather than the exception in all fields of human endeavor in that of biological sciences the ‘wane’ is all too often indicative of a justified loss of faith in the rational and methodical approach that had at first raised so much hope. ~ Rita Levi-Montalcini 1909 to 2012 Neurobiologist
Actually everything that can be known has a number; for it is impossible to grasp anything with the mind or to recognize it without this. ~ Philolaus c. 470 – c. 385 BC - Scientist and Philosopher
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
