It is thus probable that germs of the lowest organisms known to us are continually being carried away from the earth and the other planets upon which they exist. As seeds in general so most of these spores thus carried away will no doubt meet death in the cold infinite space of the universe. Yet a small number of spores will fall on some other world and may there be able to spread life if conditions be suitable. ~ Svante Arrhenius 1859 to 1927 - Physical Chemist

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
