Measuring The Surface Energy of A Liquid
As first described by Thomas Young in 1805 in the Philosophical Transactions of the Royal Society of London, it is the interaction between the forces of cohesion and the forces of adhesion which determines whether or not wetting, the spreading of a liquid over a surface, occurs. If complete wetting does not occur, then a bead of liquid will form, with a contact angle which is a function of the surface energies of the system.
Surface energy is most commonly quantified using a contact angle goniometer and a number of different methods.

“... there is no way of measuring the damage to a society when a whole texture of humanity is kept from realizing its own power, when the woman architect who might have reinvented our cities sits barely literate in a semilegal sweatshop on the Texas- Mexican border, when women who should be founding colleges must work their entire lives as domestics ...”

—Emile Durkheim (1858–1917)
