We cannot define anything precisely! If we attempt to we get into that paralysis of thought that comes to philosophers who sit opposite each other one saying to the other ‘You don’t know what you are talking about!’ The second one says ‘What do you mean by know? What do you mean by talking? What do you mean by you?’ and so on. ~ Richard Feynman 1918 to 1988
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

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
All increasing or dominant species (and it is from these that new species arise) vary considerably in all their parts organs and faculties in every generation. ~ Alfred Russel Wallace 1823 to 1913 - Zoologist Evolutionary Biologist
