Quirin Vrehen

Quirin Vrehen is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Quirin Vrehen rather than just read about it. In short: Quirinus Henricus Franciscus "Quirin" Vrehen (25 February 1932 – 5 February 2023) was a Dutch physicist. He served as head physicist of the Philips Natuurkundig Laboratorium.

Key takeaways

Quirin Vrehen belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Quirin Vrehen to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Quirin Vrehen from memory before moving on to harder problems.

Reference excerpt

Quirinus Henricus Franciscus "Quirin" Vrehen (25 February 1932 – 5 February 2023) was a Dutch physicist. He served as head physicist of the Philips Natuurkundig Laboratorium.

Life Vrehen was born on 25 February 1932 in 's-Hertogenbosch. He obtained a PhD in physics from Utrecht University in 1963 under professor Volger with a thesis on electron spin resonance and optical studies of solids. From 1963 to 1966 he worked in the United States at the MIT National Magnetic Laboratory. At the institute he worked on magneto-optical experiments on semiconductors. Vrehen then returned to the Netherlands and started working at the Philips Natuurkundig Laboratorium. At the laboratorium he served as leader of the spectroscopy group. From 1980 to 1985 he focused on laser spectroscopy. He later became head physicist at the laboratorium. Vrehen was elected member of the Royal Netherlands Academy of Arts and Sciences in 1988. He died on 5 February 2023 in Eindhoven.

Worked examples

Example 1 — a first encounter with Quirin Vrehen

Start with the simplest possible case. Write down what Quirin Vrehen claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Quirin Vrehen 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 Quirin Vrehen 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 Quirin Vrehen

In research: Quirin Vrehen appears in physics 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 Quirin Vrehen 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: Quirin Vrehen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1932 births, 2023 deaths, 20th-century Dutch physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Quirin Vrehen 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.
