Chemistry begins in the stars. The stars are the source of the chemical elements which are the building blocks of matter and the core of our subject. ~ Peter Atkins - 1940 to present
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
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
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
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
Science is the acceptance of what works and the rejection of what does not. That needs more courage than we might think. - Jacob Bronowski 1908 to 1974 Mathematician Biologist
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
