Henning Illies

Henning Illies 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 Henning Illies rather than just read about it. In short: Jürgen Henning Illies (14 March 1924 – 2 August 1982) was a German geologist, an expert in taphrogenesis (rift formation). Apart from his work on rifts, including the Rhine Rift Valley, he is known for his contributions to Chilean geology.

Key takeaways

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

Reference excerpt

Jürgen Henning Illies (14 March 1924 – 2 August 1982) was a German geologist, an expert in taphrogenesis (rift formation). Apart from his work on rifts, including the Rhine Rift Valley, he is known for his contributions to Chilean geology. Illies was active at the Austral University of Chile in Valdivia where he mapped the geology of the Old Valdivia Province in 1956–1957. After the mapping was done he studied more specific geologic problems in Chile the years of 1958–59. Illies is currently regarded as a "founding father" of the geology department of the Austral University of Chile. From 1973 onwards he was a member of the German Academy of Sciences Leopoldina.

Notable publications 1960. Geologie der Gegend von Valdivia/Chile. Neues Jahrbuch fur Geologie u. Palaontlogie, Abhandlungen Bd. 111, S. 30–110. Stuttgart. 1981. Mechanism of graben formation. Tectonophysics, 73(1), 249–266.

Worked examples

Example 1 — a first encounter with Henning Illies

Start with the simplest possible case. Write down what Henning Illies 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 Henning Illies 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 Henning Illies 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 Henning Illies

In research: Henning Illies 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 Henning Illies 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: Henning Illies is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1924 births, 1982 deaths, 20th-century Chilean geologists, so understanding it makes those chapters shorter.
In everyday life: Look for Henning Illies 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.
