Surely it is not knowledge but learning; not owning but earning; not being there but getting there; that gives us the greatest pleasure. ~ Carl Friedrich Gauss 1777 – 1855 - Mathematician and Physicist
Euclid’s work ought to have been any educationist’s nightmare… it never offers any “motivations ” it has no illuminating “asides ” it does not attempt to make anything “intuitive ” and it avoids “applications” to a fault. It is so “humorless” in its mathematical purism that… …it should have been spurned by students and “progressive” teachers in every generation. But it nevertheless survived intact all the turmoils ravages and illiteracies of the dissolving Roman Empire of the early Dark Ages of the Crusades and of the plagues and famines of the later Middle Ages. ~ Salomon Bochner 1899 – 1982 - Mathematician
Although Nature needs thousands or millions of years to create a new species man needs only a few dozen years to destroy one. ~ Victor Scheffer 1906 to 2011 - Biologist
