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
Euclid’s work ought to have been any educationist’s nightmare… it never offers any “motivations ” it has no illuminating “asides ” it does not attempt to make anything “intuitive ” and it avoids “applications” to a fault. It is so “humorless” in its mathematical purism that… …it should have been spurned by students and “progressive” teachers in every generation. But it nevertheless survived intact all the turmoils ravages and illiteracies of the dissolving Roman Empire of the early Dark Ages of the Crusades and of the plagues and famines of the later Middle Ages. ~ Salomon Bochner 1899 – 1982 - Mathematician

The condition of matter I have dignified by the term Electronic THE ELECTRONIC STATE. What do you think of that? Am I not a bold man ignorant as I am to coin words? ~ Michael Faraday 1791 – 1867
It is a platitude that pure mathematics can have unexpected consequences and affect even daily life. ~ J.E. Littlewood 1885 – 1977 - Mathematician
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 Mathematician and Astronomer
It is thus probable that germs of the lowest organisms known to us are continually being carried away from the earth and the other planets upon which they exist. As seeds in general so most of these spores thus carried away will no doubt meet death in the cold infinite space of the universe. Yet a small number of spores will fall on some other world and may there be able to spread life if conditions be suitable. ~ Svante Arrhenius 1859 to 1927 - Physical Chemist
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
