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
No two electrons in the same state? That is why atoms are so unnecessarily big and why metal and stone are so bulky. (Explaining that atoms are as large as they are because of Wolfgang Pauli’s Principle.) ~ Paul Ehrenfest 1880 – 1933

With monads and diads and pentads and triads My brain has been addled completely; And what’s really meant by ‘something-valent ’ Is a question I give up discretely. ~ John Cargill Brough - 1834 to 1872
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

Although the alternate ‘wax and wane’ cycles are the rule rather than the exception in all fields of human endeavor in that of biological sciences the ‘wane’ is all too often indicative of a justified loss of faith in the rational and methodical approach that had at first raised so much hope. ~ Rita Levi-Montalcini 1909 to 2012 Neurobiologist
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
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
