Trial by combat of wits in disputations has no attraction for the seeker after truth; to him the appeal to experiment is the last and only test of the merit of an opinion conjecture or hypotheses. - Joseph Mellor 1869 to 1938 Chemist
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

Pierre Curie voluntarily exposed his arm to the action of radium for several hours. This resulted in damage resembling a burn that developed progressively and required several months to heal. Henri Becquerel had by accident a similar burn as a result of carrying in his vest pocket a glass tube containing radium salt. He came to tell us of this evil effect of radium exclaiming in a manner at once delighted and annoyed: “I love it but I owe it a grudge.” - Marie Curie 1867 to 1934 Chemist Physicist

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
Nearly 2.5 billion years of prokaryotic cells and nothing else – two-thirds of life’s history in stasis at the lowest level of recorded complexity… Why did life remain at stage 1 for two-thirds of its history if complexity offers such benefits? ~ Stephen Jay Gould 1941 to 2002 - Paleontologist
Physics is littered with the corpses of dead unified field theories. ~ Freeman Dyson b. 1923
On the principle of successive variations not always supervening at an early age and being inherited at a corresponding not early period of life we can clearly see why the embryos of mammals birds reptiles and fishes should be so closely alike and should be so unlike the adult forms. ~ Charles Darwin 1809 to 1882 - Naturalist Evolutionary Biologist
The literary convention that numbers less than 10 should be given in words is often highly unsuitable in mathematics… The excessive use of the word forms is regrettably spreading at the present time. ~ J.E. Littlewood 1885 – 1977 - Mathematician
