Physics is actually too hard for physicists. ~ David Hilbert 1862 to 1943 (Mathematician)
Suppose we have an unknown number of objects. When counted in threes 2 are left over when counted in fives 3 are left over and when counted in sevens 2 are left over. How many objects are there? ~ Sunzi The Mathematical Classic of Sunzi - Chinese mathematics problem from c. 450 AD

In my experience most mathematicians are intellectually lazy and especially dislike reading experimental papers. ~ Francis Crick 1916 – 2004 - Molecular Biologist
Nearly 2.5 billion years of prokaryotic cells and nothing else – two-thirds of life’s history in stasis at the lowest level of recorded complexity… Why did life remain at stage 1 for two-thirds of its history if complexity offers such benefits? ~ Stephen Jay Gould 1941 to 2002 - Paleontologist
The condition of matter I have dignified by the term Electronic THE ELECTRONIC STATE. What do you think of that? Am I not a bold man ignorant as I am to coin words? ~ Michael Faraday 1791 – 1867
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
A physicist is an atom’s way of knowing about atoms. - George Wald 1906 to 1997 Neurobiologist
Science is vastly more stimulating to the imagination than the classics. - J. B. S. Haldane 1892 to 1964 Biologist
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
