Johannes Diderik van der Waals
Johannes Diderik van der Waals (23 November 1837 – 8 March 1923) was a Dutch theoretical physicist and thermodynamicist famous for his work on an equation of state for gases and liquids.
His name is primarily associated with the van der Waals equation of state that describes the behavior of gases and their condensation to the liquid phase.
His name is also associated with van der Waals forces (forces between stable molecules), with van der Waals molecules (small molecular clusters bound by van der Waals forces), and with van der Waals radii (sizes of molecules).
As James Clerk Maxwell said about Van der Waals, "there can be no doubt that the name of Van der Waals will soon be among the foremost in molecular science."
In his 1873 thesis, van der Waals noted the non-ideality of real gases and attributed it to the existence of intermolecular interactions.
He introduced the first equation of state derived by the assumption of a finite volume occupied by the constituent molecules.
Spearheaded by Ernst Mach and Wilhelm Ostwald, a strong philosophical current that denied the existence of molecules arose towards the end of the 19th century.
The molecular existence was considered unproven and the molecular hypothesis unnecessary.
At the time van der Waals' thesis was written (1873), the molecular structure of fluids had not been accepted by most physicists, and liquid and vapor were often considered as chemically distinct.
But van der Waals's work affirmed the reality of molecules and allowed an assessment of their size and attractive strength.
His new formula revolutionized the study of equations of state.
By comparing his equation of state with experimental data, Van der Waals was able to obtain estimates for the actual size of molecules and the strength of their mutual attraction.
The effect of Van der Waals's work on molecular physics in the 20th century was direct and fundamental.
By introducing parameters characterizing molecular size and attraction in constructing his equation of state, Van der Waals set the tone for modern molecular science.
That molecular aspects such as size, shape, attraction, and multipolar interactions should form the basis for mathematical formulations of the thermodynamic and transport properties of fluids is presently considered an axiom.
With the help of the van der Waals's equation of state, the critical-point parameters of gases could be accurately predicted from thermodynamic measurements made at much higher temperatures.
Nitrogen, oxygen, hydrogen, and helium subsequently succumbed to liquefaction.
Heike Kamerlingh Onnes was significantly influenced by the pioneering work of van der Waals.
In 1908, Onnes became the first to make liquid helium; this led directly to his 1911 discovery of superconductivity.
Van der Waals started his career as a school teacher.
He became the first physics professor of the University of Amsterdam when in 1877 the old Athenaeum was upgraded to Municipal University.
Van der Waals won the 1910 Nobel Prize in physics for his work on the equation of state for gases and liquids.
Tilly van der Zwaard
Tilly van der Zwaard( 18 January 1938 – 6 February 2019) was a middle distance runner from the Netherlands.
At the 1962 European Athletics Championships in Belgrade she won a bronze medal in the 400 m event, behind Maria Itkina of the Soviet Union and Joy Grieveson of Great Britain.
Van der Zwaard twice represented her native country in the 400 m event at the Summer Olympics, in 1964 and 1968.
Her best achievement was sixth place in 1964.
She was born Mathilda Catrina van der Zwaard.
On 25 November 1964 she married Ger van der Made and changed her name to van der Made -van der Zwaard.
After divorce she dropped van der Made from her name.
She died in February 2019.

Dirk van den Broek
Dirk van den Broek( born 27 March 1924) is a Dutch businessman, founder of the" Samenwerkende Dirk van den Broek Bedrijven", one of the largest family- owned businesses in the Netherlands.
The company includes grocery stores, travel agencies, drug stores, liquor stores and various other ventures.
Born in Amsterdam in 1924, Dirk van den Broek was the son of a farmer.
Inspired by his mother who ran her own milk production and delivery operation from their farm, he and his wife Joukje started a small grocery store.
Dirk van den Broek is a family owned and operated business with a rich history.
Starting with door- to- door milk cart business in Amsterdam and the first brick- and- mortar milk store in 1942, Dirk van den Broek is one of the most recognized brands in the Netherlands.
Currently, there are 120 stores in the chain and the unique selling proposition is excellent prices and quality with strong customer centric special offers.
Dirk van den Broek was made Officer in the Order of Orange Nassau in 1990 by Queen Beatrix of the Netherlands.
Dirk van den Broek is married and has five children, all of whom are still active in the family business.
