Olaf Rogstad

Olaf Rogstad is a 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 Olaf Rogstad rather than just read about it. In short: Olaf Rogstad (4 April 1877 – 7 July 1969) was a Norwegian engineer and civil servant. He was also a glaciologist.

Key takeaways

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

Reference excerpt

Olaf Rogstad (4 April 1877 – 7 July 1969) was a Norwegian engineer and civil servant. He was also a glaciologist. He was decorated as a Knight, First Class of Order of St. Olav.

Personal life Rogstad was born in Elverum, a son of farmer Ole Rogstad and Petronelle Marthea Grøtting. He was married to Hildur Louise Møystad from 1903.

Career Rogstad finished his secondary education in 1895 and graduated from the Trondhjems Tekniske Læreanstalt in 1898. He was hired in the Canal Agency in 1898, and the Water Agency in 1907 as head of the hydrographic department. He was promoted to chief engineer in 1920 and director in 1920. From 1925 to 1947 he was the director-general of the Norwegian Water Resources and Electricity Agency, except for the period 1942 to 1945 when he was removed by the German occupiers. Hans Skarphagen was the one who took over in 1942.

Worked examples

Example 1 — a first encounter with Olaf Rogstad

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

In research: Olaf Rogstad appears in 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 Olaf Rogstad 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: Olaf Rogstad is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1877 births, 1969 deaths, Directors of government agencies of Norway, so understanding it makes those chapters shorter.
In everyday life: Look for Olaf Rogstad 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.
