"It may be said that studies of the coagulation resistance of colloids have been responsible for the creation of a new science - the science of surface forces and their manifestations in the properties of thin (but polymolecular) layers. In turn, research in this new field of knowledge has contributed to neighboring sciences: studies of molecular forces, liquid crystals, electrochemistry, mass transport theory, certain branches of nonequilibrium thermodynamics, biophysics, hydraulic engineering, and soil science and the science of the earth's crust. It is natural, therefore, to combine in one book the problems of colloid stability and the stability of thin films."
