Geometry inasmuch as it is concerned with real space is no longer considered a part of pure mathematics; like mechanics and physics it belongs among the applications of mathematics. ~ Hermann Weyl 1885 to 1955 - Mathematician and Theoretical Physicist
I am not insensible of the advantage which accrues to Applied Mathematics from the co-operation of the Pure Mathematician and this co-operation is not infrequently called forth by the very imperfections of writers on Applied Mathematics. ~ Ronald Fisher 1890 – 1962 - Mathematician Statistician Evolutionary Biologist

The chemists are a strange class of mortals impelled by an almost insane impulse to seek their pleasures amid smoke and vapor soot and flame poisons and poverty; yet among all these evils I seem to live so sweetly that may I die if I were to change places with the Persian king. ~ Johann Joachim Becher - 1635 to 1682
