32893 van der Waals           Discovered 1994 Mar. 9 by E. W. Elst at Caussols.
Johannes Diderik van der Waals (1837-1923), a Dutch physicist and thermodynamicist at Leiden University, is known for his equation of state for the merging of liquid and gas phases of the same substance in a continuous manner. In 1910 he received the Nobel prize for physics.
