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

A physicist is an atom’s way of knowing about atoms. - George Wald 1906 to 1997 Neurobiologist
