Knut S. Heier

Knut S. Heier 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 Knut S. Heier rather than just read about it. In short: Knut Sigurdsøn Heier (20 April 1929 – 14 September 2008) was a Norwegian geochemist. He was a professor at the University of Oslo and the Norwegian Institute of Technology between 1968 and 1989, and was also director of the Norwegian Geological Survey.

Key takeaways

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

Reference excerpt

Knut Sigurdsøn Heier (20 April 1929 – 14 September 2008) was a Norwegian geochemist. He was a professor at the University of Oslo and the Norwegian Institute of Technology between 1968 and 1989, and was also director of the Norwegian Geological Survey. Heier also spent parts of his research abroad, and was a member of the Apollo Project.

Education He was born in Bærum Municipality as the son of an engineer. He graduated from the University of Oslo with the cand.real. degree in 1954, with a paper on tungsten. He subsequently turned down a job offer from the private sector to work on a doctoral thesis. He started with a year of field work at Bø i Vesterålen, from 1955, and then went to Oxford to conduct laboratory work. He finally took the dr.philos. degree in 1960. He then did postdoctoral research for two years at Rice University. He was offered a senior fellowship at the Australian National University, but instead returned to Norway.

Later career He was a professor of geochemistry at the University of Oslo from 1968 to 1979 and in geology at the Norwegian Institute of Technology from 1979 to 1989. In addition to these two fields, he published scientific works in petrology, mineralogy and geophysics—130 works in total. He also participated with neutron activation analysis in the Apollo Project. During his time, Norway was an emerging petroleum power. Heier helped ensure that research positions relevant to petroleum were funded. This has been considered as a necessary renewal of the focus of geology in Norway. From 1974 to 1994 he presided over the Norwegian Geological Survey. He was also an adjunct professor at the Norwegian University of Science and Technology, and a member of Norway's three learned societies; the Royal Norwegian Society of Sciences and Letters, the Norwegian Academy of Science and Letters and the Norwegian Academy of Technological Sciences. He received the Brøgger Prize, named for Waldemar Christofer Brøgger, in 2007. Heier was married and had children. They resided at Stabekkåsen. He died in September 2008, at 79 years of age.

Worked examples

Example 1 — a first encounter with Knut S. Heier

Start with the simplest possible case. Write down what Knut S. Heier 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 Knut S. Heier 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 Knut S. Heier 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 Knut S. Heier

In research: Knut S. Heier 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 Knut S. Heier 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: Knut S. Heier is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1929 births, 2008 deaths, Academic staff of the Norwegian Institute of Technology, so understanding it makes those chapters shorter.
In everyday life: Look for Knut S. Heier 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.
