Nothing can be more certain than this: that we are just beginning to learn something of the wonders of the world on which we live and move and have our being. ~ William Ramsay - 1852 to 1916
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

Still I had a lurking question. Would it not be better if one could really ‘see’ whether molecules as complicated as the sterols or strychnine were just as experiment suggested? ~ Dorothy Hodgkin - 1910 to 1984

A detective with his murder mystery a chemist seeking the structure of a new compound use little of the formal and logical modes of reasoning. Through a series of intuitions surmises fancies they stumble upon the right explanation and have a knack of seizing it when it once comes within reach. ~ Gilbert Lewis 1875 – 1946
