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
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

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.

An experiment is a question which science poses to Nature and a measurement is the recording of Nature’s answer. - Max Planck 1858 to 1947 Theoretical Physicist
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
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
Physics is littered with the corpses of dead unified field theories. ~ Freeman Dyson b. 1923
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
