william zisman's contribution of what is called today as the zisman plot revolutionized the world of adhesive bonding and surface chemistry by giving a fast, effective, and quantitative way to measure the wettability or critical surface tension of a solid. this spawned the work of many others over the past few decades. this spans from dann's work in the late 1960s to david and neumann's work in 2014. the zisman plot is still used today, and it has many variations since the y-axis is unitless and can be found more easily and accurately using modern regression software packages.
