With monads and diads and pentads and triads My brain has been addled completely; And what’s really meant by ‘something-valent ’ Is a question I give up discretely. ~ John Cargill Brough - 1834 to 1872
The finding of the double helix thus brought us not only joy but great relief. It was unbelievably interesting and immediately allowed us to make a serious proposal for the mechanism of gene duplication. ~ James Watson 1928 – Present - Geneticist

I am not insensible of the advantage which accrues to Applied Mathematics from the co-operation of the Pure Mathematician and this co-operation is not infrequently called forth by the very imperfections of writers on Applied Mathematics. ~ Ronald Fisher 1890 – 1962 - Mathematician Statistician Evolutionary 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
