Haavard Martinsen

Haavard Martinsen is a chemistry 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 Haavard Martinsen rather than just read about it. In short: Haavard Martinsen (6 February 1879 – 2 August 1967) was a Norwegian chemist and industrial leader. He was born in Nedre Eiker to Gustav Martinsen and Johanna Jeremiassen.

Key takeaways

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

Reference excerpt

Haavard Martinsen (6 February 1879 – 2 August 1967) was a Norwegian chemist and industrial leader. He was born in Nedre Eiker to Gustav Martinsen and Johanna Jeremiassen. He graduated as chemist from the University of Dresden in 1902. From 1918 to 1949 he was director of the mill Bjølsen Valsemølle. He served as mayor of Kristiania from 1920 to 1922. He was decorated Knight, First Class of the Order of St. Olav in 1939, was Commander of the French Legion of Honour, Grand Officer of the Order of Orange-Nassau, and was awarded the Order of the British Empire.

Worked examples

Example 1 — a first encounter with Haavard Martinsen

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

In research: Haavard Martinsen appears in chemistry 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 Haavard Martinsen 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: Haavard Martinsen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1879 births, 1967 deaths, Commanders of the Legion of Honour, so understanding it makes those chapters shorter.
In everyday life: Look for Haavard Martinsen 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.
