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
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

Before the Copernican revolution it was natural to suppose that God’s purposes were specifically concerned with the earth but now this has become an unplausible hypothesis. If it is the purpose of the Cosmos to evolve mind we must regard it as rather incompetent in having produced so little in such a long time. ~ Bertrand Russell 1872 – 1970 - Mathematician and Philosopher
In practical applications we are concerned only with comparatively small numbers; only stellar astronomy and atomic physics deal with ‘large’ numbers and they have very little more practical importance as yet than the most abstract pure mathematics. ~ G. H. Hardy 1877 – 1947 - Mathematician
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
I saw that people trying to synthesize gold and silver were working in ignorance and by false methods; I then perceived that they belonged to two classes the dupers and the duped. I pitied both of them. ~ Geber c. 712 – c. 815 AD
Actually everything that can be known has a number; for it is impossible to grasp anything with the mind or to recognize it without this. ~ Philolaus c. 470 – c. 385 BC - Scientist and Philosopher
In its efforts to learn as much as possible about nature modern physics has found that certain things can never be “known” with certainty. Much of our knowledge must always remain uncertain. The most we can know is in terms of probabilities. ~ Richard Feynman 1918 to 1988
The time however has arrived when biology must like the other sciences make a fresh start in a purely speculative direction free from all entanglement with medical or any other art. ~ Auguste Compte 1798 to 1857 - Philosopher of Science
