What exactly is mathematics? Many have tried but nobody has really succeeded in defining mathematics; it is always something else. Roughly speaking people know that it deals with numbers figures with relations operations and that its formal procedures involving axioms proofs lemmas theorems have not changed since the time of Archimedes. ~ Stan Ulam 1909 – 1984 - Mathematician
I accept no principles of physics which are not also accepted in mathematics. ~ René Descartes 1596 to 1650

Although Nature needs thousands or millions of years to create a new species man needs only a few dozen years to destroy one. - Victor Scheffer 1906 to 2011 Biologist
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
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
Chemistry is necessarily an experimental science: its conclusions are drawn from data and its principles supported by evidence from facts. ~ Michael Faraday - 1791 to 1867
Did the genome of our cave-dwelling predecessors contain a set or sets of genes which enable modern man to compose music of infinite complexity and write novels with profound meaning? …It looks as though the early Homo was already provided with the intellectual potential which was in great excess of what was needed to cope with the environment of his time.” - Susumu Ohno 1928 to 2000 Geneticist
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
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
