The physical chemists never use their eyes and are most lamentably lacking in chemical culture. It is essential to cast out from our midst root and branch this physical element and return to our laboratories. ~ Henry Edward Armstrong 1848 to 1937

Falsity in intellectual action is intellectual immorality. - Thomas Chrowder Chamberlin 1843 to 1928 Geologist
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
Macroscopic objects as we see them all around us are governed by a variety of forces derived from a variety of approximations to a variety of physical theories. In contrast the only elements in the construction of black holes are our basic concepts of space and time. They are thus almost by definition the most perfect macroscopic objects there are in the universe. ~ Subrahmanyan Chandrasekhar 1910 to 1995
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
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
But though the professed aim of all scientific work is to unravel the secrets of nature it has another effect not less valuable on the mind of the worker. It leaves him in possession of methods which nothing but scientific work could have led him to invent. ~ James Clerk Maxwell 1831 to 1879
All of physics is either impossible or trivial. It is impossible until you understand it and then it becomes trivial. ~ Ernest Rutherford 1871 to 1937
