The notion of a critical exponent was first used by Van der Waals in 1893 for describing the critical behavior of the surface tension. He also noticed in the early 1890's that experimental data on capillarity indicated a nonclassical value for the surface tension exponent. Verschaffelt found that this was due to the fact that the coexistence curve exponent beta was nonclassical. In 1900, he established precise nonclassical values for the exponents beta and delta. Even though from this time onwards the "cubic law" for fluid coexistence curves was accepted, the true implication of Verschaffelt's results, namely the failure of classical theory, was not appreciated. Some '''reasonsfor this lack of impact will be given.

If I weren't on the outside of the paywall, I might have checked out the reasons then added a sentence to this biography, which is extremely light on V's specific accomplishments. &mdash; MaxEnt 01:37, 28 January 2020 (UTC)
