Reference excerpt

Haaken Christian Mathiesen (9 October 1896 – 30 July 1975) was a Norwegian businessperson, who founded the Norwegian branch of Texaco.

Personal life He was born in Trondhjem as a son of landowner and politician Christian Pierre Mathiesen (1870–1953) and Celina Ihlen (1874–1948). On the paternal side he was a grandson of Haaken C. Mathiesen, a nephew of Haaken L. Mathiesen and a first cousin of Jørgen Mathiesen. On the maternal side he was a grandson of Jacob Thurmann Ihlen and Belgian citizen Ambrosine Pauline Rouquet. Through his mother's sisters he was a nephew of Arthur Knagenhjelm and Jens Gran Gleditsch and a second cousin of Kai Knagenhjelm. Through his grandfather's brothers Niels and Wincentz Thurmann Ihlen he was a second cousin of Nils, Joakim and Alf Ihlen. In 1931 he married Magdalene Bull Wilhelmsen, a daughter of Finn Wilhelmsen and Magdalene Fredrikke Bull.

Career He finished his secondary education in 1914. He attended Harvard University and studied elsewhere in France and Germany. He was the founder of Texaco Norway, and chaired Texaco Norway and Norsk Texaco Oil. After mergers and acquisitions through history, the company is now known as YX Energi. He was a member of the board or supervisory council of many companies, including Wilh. Wilhelmsen, Fred. Olsen & Co, Forsikringsselskapet Norden, Den norske Creditbank, Arthur Mathiesen & Co, Elkem, Norsk Elektrisk & Brown Boveri, Tønsberg Margarinfabrik and Farmand Fabriker. He died in July 1975 and was buried in Gamle Aker.

Worked examples

Example 1 — a first encounter with Haaken C. Mathiesen Jr.

Start with the simplest possible case. Write down what Haaken C. Mathiesen Jr. claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Haaken C. Mathiesen Jr. 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 Haaken C. Mathiesen Jr. 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 Haaken C. Mathiesen Jr.

In research: Haaken C. Mathiesen Jr. appears in mathematics 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 Haaken C. Mathiesen Jr. 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: Haaken C. Mathiesen Jr. is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1896 births, 1975 deaths, 20th-century Norwegian businesspeople, so understanding it makes those chapters shorter.
In everyday life: Look for Haaken C. Mathiesen Jr. 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.
