The ultimate truths of mathematics then cannot be established by any experimental proof that the deductions from them are true; since the supposed experimental proof takes them for granted. ~ Herbert Spencer 1885 – 1977 - Philospher
I believe that new mathematical schemata new systems of axioms certainly new systems of mathematical structures will be suggested by the study of the living world. ~ Stan Ulam 1909 – 1984 - Mathematician

Everything that human beings or living animals do is done by protein molecules. And therefore the kind of proteins that one has and therefore the ability one has is determined by the genes that one has. ~ Har Gobind Khorana 1922 – 2011 - Molecular Biologist
In our work we are always between Scylla and Charybdis; we may fail to abstract enough and miss important physics or we may abstract too much and end up with fictitious objects in our models turning into real monsters that devour us. ~ Murray Gell-Mann b. 1929
In my experience most mathematicians are intellectually lazy and especially dislike reading experimental papers. ~ Francis Crick 1916 – 2004 - Molecular Biologist
I accept no principles of physics which are not also accepted in mathematics. ~ René Descartes 1596 to 1650
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?
