Ginjaar worked as a researcher at the Organisation for Applied Scientific Research from August 1956 until December 1977 and served as Director of the department of Climatology from February 1970 until December 1977. Ginjaar served on the Provincial-Council of South Holland from July 1971 until December 1977.

After the election of 1977 Ginjaar was appointed as Minister of Health and Environment in the Cabinet Van Agt-Wiegel, taking office on 19 December 1977. Ginjaar served as acting Minister for Science Policy from 1 April 1979 until 3 May 1979 following the death of Rinus Peijnenburg. In December 1980, Ginjaar announced that he wouldn't stand for the election of 1981 but wanted to run for the Senate. Ginjaar was elected as a Member of the Senate after the Senate election of 1981, taking office on 25 August 1981 serving as a frontbencher chairing the parliamentary committee for Higher Education and Science Policy and the parliamentary committee for Housing and Spatial Planning and spokesperson for the Environment, Higher Education and Agriculture. The Cabinet Van Agt–Wiegel was replaced by the Cabinet Van Agt II following the cabinet formation of 1981 on 11 September 1981. Ginjaar also served as Chairmen of the People's Party for Freedom and Democracy from 29 November 1986 until 4 October 1991. Ginjaar served as a distinguished professor of Medical ethics at the Utrecht University from 1 September 1982 until 1 January 1986 and also served as Chairman of the Education board of the Utrecht University from 10 September 1982 until 1 January 1986 and a distinguished professor of Climatology and Medical research at the State University of Limburg from 1 March 1990 until 1 September 1994. Ginjaar was selected as Parliamentary leader of the People's Party for Freedom and Democracy in the Senate following the election of Frits Korthals Altes as President of the Senate, serving from 11 March 1997 until 14 September 1999. In November 2002 Ginjaar announced his retirement from national politics and that he wouldn't stand for the Senate election of 2003 and continued to serve until the end of the parliamentary term on 10 June 2003. Ginjaar was known for his abilities as a manager and policy wonk. Ginjaar continued to comment on political affairs until his death four months later at the age of 75. His wife Nell was also a politician who served as State Secretary for Education and Sciences from 5 November 1982 until 7 November 1989.

Worked examples

Example 1 — a first encounter with Leendert Ginjaar

Start with the simplest possible case. Write down what Leendert Ginjaar claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Leendert Ginjaar before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Leendert Ginjaar ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Leendert Ginjaar

In research: Leendert Ginjaar appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Leendert Ginjaar in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Leendert Ginjaar is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1928 births, 2003 deaths, 20th-century Dutch chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Leendert Ginjaar outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
