Today (March 8, 1923) is the Memorial Day of Johannes van der Waals, winner of the Nobel Prize for his study of the equation of gases and liquids.
Johannes van der Waals was born on November 23, 1837 in Leiden,
Netherlands. He completed his primary education in his hometown. In his spare
time, he studied at the University of Leighton from 1862 to 1865. He then earned
a degree in mathematics and physics. From 1856 to 1864 he taught mathematics
and physics as an intermediate teacher at Deventer. In 1866 he emigrated to The
Hawk, first as a teacher and later as a director of the high schools in the
city. He received his doctorate in 1873. He also did research on the continuity
of the gas and liquid state. In his study, he proposed an "equation of
state" that embraced both the gaseous and liquid states. Van der Waals is
used in the position equation to describe the behaviour of gases and their
liquid state compression. As well as the Van der Waals force between fixed
molecules, and the small molecular clusters bound by these forces are
associated with the Van der Waals molecules and van der Waals radii.
The second major discovery was published in 1880 (The Law of
Corresponding States). By quantitative estimates of temperature, pressure, and
volume, a common form of constant equation applies to all materials. His best
research is on the van der Waals law, the Van der Waals radius, the van der
Waals surface, and the van der Waals molecule. He served as secretary of the
Royal Society from 1896 to 1912. In 1908 he retired from the University of
Amsterdam. 1910 Nobel Prize in Physics. Modern molecular physicist (molecular
theory), who passed away on March 08, 1923, in Amsterdam, the Netherlands.
