Benjamin Franklin performed a beautiful experiment using surfactants; on a pond at Clapham Common he poured a small amount of oleic acid a natural surfactant which tends to form a dense film at the water-air interface. He measured the volume required to cover all the pond. Knowing the area he then knew the height of the film something like three nanometers in our current units. ~ Pierre-Gilles de Gennes 1932 to 2007
Science is the acceptance of what works and the rejection of what does not. That needs more courage than we might think. - Jacob Bronowski 1908 to 1974 Mathematician Biologist

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
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

Trial by combat of wits in disputations has no attraction for the seeker after truth; to him the appeal to experiment is the last and only test of the merit of an opinion conjecture or hypotheses. ~ Joseph Mellor - 1869 to 1938
On the principle of successive variations not always supervening at an early age and being inherited at a corresponding not early period of life we can clearly see why the embryos of mammals birds reptiles and fishes should be so closely alike and should be so unlike the adult forms. ~ Charles Darwin 1809 to 1882 - Naturalist Evolutionary Biologist
This is an era of specialists each of whom sees his own problem and is unaware of or intolerant of the larger frame into which it fits. ~ Rachel Carson 1907 to 1964 - Marine 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
