Olav Liestøl

Olav Liestøl is a earth science 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 Olav Liestøl rather than just read about it. In short: Olav Liestøl (24 February 1916 – 3 April 2002) was a Norwegian glaciologist. He was born in Kristiania (now Oslo) to the folklorist and politician Knut Liestøl, but grew up in Blommenholm.

Key takeaways

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

Reference excerpt

Olav Liestøl (24 February 1916 – 3 April 2002) was a Norwegian glaciologist. He was born in Kristiania (now Oslo) to the folklorist and politician Knut Liestøl, but grew up in Blommenholm. He was a member of Milorg during the occupation of Norway by Nazi Germany, and took the cand.real. degree at the University of Oslo in 1945. From 1948 to his retirement in 1986 he worked as a glaciologist at the Norwegian Polar Institute, and was described as "Norway's most recognized glaciologist". He mainly studied the geology of Svalbard, but also Antarctica and elsewhere. From 1985 he was also an adjunct professor at the University of Oslo. He resided at Blommenholm. He died in April 2002.

Legacy The glacier of Liestølbreen in Torell Land at Spitsbergen, Svalbard is named after him.

Worked examples

Example 1 — a first encounter with Olav Liestøl

Start with the simplest possible case. Write down what Olav Liestøl claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, 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 Olav Liestøl 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 Olav Liestøl 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 Olav Liestøl

In research: Olav Liestøl appears in earth science 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 Olav Liestøl 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: Olav Liestøl is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1916 births, 2002 deaths, 20th-century Norwegian geologists, so understanding it makes those chapters shorter.
In everyday life: Look for Olav Liestøl 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.
