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

Before the Copernican revolution it was natural to suppose that God’s purposes were specifically concerned with the earth but now this has become an unplausible hypothesis. If it is the purpose of the Cosmos to evolve mind we must regard it as rather incompetent in having produced so little in such a long time. ~ Bertrand Russell 1872 – 1970 - Mathematician and Philosopher
The development of biology is going to destroy to some extent our traditional grounds for ethical belief and it is not easy to see what to put in their place. ~ Francis Crick 1916 – 2004 Molecular Biologist
In practical applications we are concerned only with comparatively small numbers; only stellar astronomy and atomic physics deal with ‘large’ numbers and they have very little more practical importance as yet than the most abstract pure mathematics. ~ G. H. Hardy 1877 – 1947 - Mathematician
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
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
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
