Reference excerpt

Klaas Sjoerds de Boer (16 November 1941 – 15 March 2022) was a Dutch astronomer and astrophysicist as well as Professor at the University of Bonn. His research mainly consisted of using data obtained with satellites and from Earth bound telescopes.

Education De Boer studied astronomy and physics at the University of Groningen and obtained his PhD there along with Stuart Pottasch on Interstellar Absorption Lines in the Ultraviolet.

Research and teaching career From 1974 to 1977 he was at the Institute for Space Research at the University of Groningen. From 1978 to 1981 he was a research associate at the Astronomy Department of the University of Wisconsin (USA) in Madison. Between 1981 and 1985 he was postdoc at the University of Tübingen and worked in 1985 for the University of Groningen in the collaborative project of the Netherlands and the United Kingdom of the observatory on La Palma, being based at Royal Greenwich Observatory in Herstmonceux. Research periods brought him to the Astronomy Department of the Princeton University (USA) und and the University of Canterbury in Christchurch (New Zealand). He became 1986 full Professor of Astronomie at the Sternwarte of the University of Bonn, successor of Hans Schmidt.

He authored or co-authored over 250 publications, half in refereed journals. He organised conferences and was editor of proceedings and published books. In addition, he wrote over 25 popular articles and some 30 essays for the internet.

Committees De Boer was Member and chairman of several committees, among them International Ultraviolet Explorer Programme Committee of the ESA (1986–1994), of the Gutachterausschusses Verbundforschung Astronomie und Astrophysik of the DLR (1991–1993 and 1995–2001), the Science Advisory Group of Gaia-Project (1998–2000) and of the Board of Directors of the international journal Astronomy & Astrophysics (2001–2011). He worked with his colleagues in Bonn toward a merger, in 2005, of the Sternwarte sich 2006 with Radioastronomischen Institut and the Institut für Astrophysik und extraterrestrische Forschung to form the Argelander Institute for Astronomy.

Worked examples

Example 1 — a first encounter with Klaas de Boer (astronomer)

Start with the simplest possible case. Write down what Klaas de Boer (astronomer) 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 Klaas de Boer (astronomer) 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 Klaas de Boer (astronomer) 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 Klaas de Boer (astronomer)

In research: Klaas de Boer (astronomer) 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 Klaas de Boer (astronomer) 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: Klaas de Boer (astronomer) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1941 births, 2022 deaths, Academic staff of the University of Bonn, so understanding it makes those chapters shorter.
In everyday life: Look for Klaas de Boer (astronomer) 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.
