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

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
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
Physicists being in no way different from the rest of the population have short memories for what is inconvenient. ~ Anthony Standen 1907 – 1993
There is no law except the law that there is no law. - John Archibald Wheeler 1911 to 2008 Theoretical Physicist
It does not help that some politicians and journalists assume the public is interested only in those aspects of science that promise immediate practical applications to technology or medicine. - Steven Weinberg 1933 to present Theoretical Physicist
Instead of being the biological center of the Universe I believe our planet is just an assembly station but one with a major advantage over most other places. The constant presence of liquid water almost everywhere on the Earth is a huge advantage for life especially for assembling life into complex forms by the process we call ‘evolution.’ ~ Fred Hoyle 1915 to 2001 - Astrophysicist
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
