Progress is made by trial and failure; the failures are generally a hundred times more numerous than the successes ; yet they are usually left unchronicled. - William Ramsay 1852 to 1916 Chemist
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

Geometry inasmuch as it is concerned with real space is no longer considered a part of pure mathematics; like mechanics and physics it belongs among the applications of mathematics. ~ Hermann Weyl 1885 to 1955 - Mathematician and Theoretical Physicist
Chemistry unlike other sciences sprang originally from delusions and superstitions and was at its commencement exactly on a par with magic and astrology. ~ Thomas Thomson - 1773 to 1852
Archimedes’ finding that the crown was of gold was a discovery; but he invented the method of determining the density of solids. Indeed discoverers must generally be inventors; though inventors are not necessarily discoverers. - William Ramsay 1852 to 1916 Chemist
I believe that new mathematical schemata new systems of axioms certainly new systems of mathematical structures will be suggested by the study of the living world. ~ Stan Ulam 1909 – 1984 - Mathematician
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
Find the number such that if the whole of it is added to one-seventh of it the result will be nineteen. ~ The Ahmes Papyrus Ancient Egyptian mathematics problem from c. 2200 BC
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
