Ingrid van Houten-Groeneveld

Ingrid van Houten-Groeneveld is a astronomy 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 Ingrid van Houten-Groeneveld rather than just read about it. In short: Ingrid van Houten-Groeneveld (Dutch pronunciation: [ˈɪŋɡrɪt fɑn ˈɦʌutə(ŋ) ˈɣrunəˌvɛlt]; née Groeneveld; 21 October 1921 – 30 March 2015) was a Dutch astronomer. Background In a jointly credited trio with Tom Gehrels and her husband Cornelis Johannes van Houten, she was the discoverer of many thousands of asteroids (credited by the Minor Planet Center with the discovery of 4,641 numbered minor planets).

Key takeaways

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

Reference excerpt

Ingrid van Houten-Groeneveld (Dutch pronunciation: [ˈɪŋɡrɪt fɑn ˈɦʌutə(ŋ) ˈɣrunəˌvɛlt]; née Groeneveld; 21 October 1921 – 30 March 2015) was a Dutch astronomer.

Background In a jointly credited trio with Tom Gehrels and her husband Cornelis Johannes van Houten, she was the discoverer of many thousands of asteroids (credited by the Minor Planet Center with the discovery of 4,641 numbered minor planets). In the Palomar–Leiden survey, Gehrels took the images using the 48-inch Schmidt telescope at Palomar Observatory and shipped the photographic plates to the van Houtens at Leiden Observatory, who analyzed them for new asteroids. The trio are jointly credited with several thousand asteroid discoveries. Van Houten-Groeneveld died on 30 March 2015, at the age of 93, in Oegstgeest, Netherlands. The Themistian main-belt asteroid 1674 Groeneveld – discovered by Karl Reinmuth at Heidelberg and independently discovered by Finnish astronomer Yrjö Väisälä in 1938, was named in her honor (M.P.C. 2901).

Worked examples

Example 1 — a first encounter with Ingrid van Houten-Groeneveld

Start with the simplest possible case. Write down what Ingrid van Houten-Groeneveld 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 Ingrid van Houten-Groeneveld 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 Ingrid van Houten-Groeneveld 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 Ingrid van Houten-Groeneveld

In research: Ingrid van Houten-Groeneveld 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 Ingrid van Houten-Groeneveld 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: Ingrid van Houten-Groeneveld is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1921 births, 2015 deaths, 20th-century Dutch astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Ingrid van Houten-Groeneveld 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.
