Reference excerpt

Terkel Nissen Rosenqvist (2 October 1921 – 1 April 2011) was a Norwegian chemist and metallurgist.

Biography He was born in Aker. His parents were businessman Einar Rosenqvist (1892–1962) and Julia (Mulka) Marija Kos (1893–1939). His brother was Ivan Th. Rosenqvist. From 1945 to 1963 he was married to Tone Barth (January 25, 1924 – October 10, 1980), the sister of Professor of Social Anthropology Fredrik Barth (born 1928). He later married Siri Sverdrup Lunden (1920–2003). He finished his secondary education in 1938 and graduated from the University of Oslo with the cand.real. degree in 1943. He was a research assistant at the university, and also worked as a chemist and metallurgist for Elektrokemisk and Christiania Spigerverk. He was appointed at the Norwegian Institute of Technology in 1945, before being an instructor from 1947 and assistant professor from 1950 at the University of Chicago. He was appointed as an acting docent at the Norwegian Institute of Technology in 1952, and after taking his dr.techn. degree in 1954 he was promoted to professor in 1955. He was a member of the Royal Norwegian Society of Sciences and Letters, the Norwegian Academy of Technological Sciences, and the Norwegian Academy of Science and Letters. He was a visiting scholar at the Massachusetts Institute of Technology from 1959 to 1960, the University of Wisconsin in 1964 and the Middle East Technical University (for UNESCO) from 1966 to 1968. He has chaired regional branches of the Norwegian Chemical Society and the Riksmål Society. He resided in Trondheim until his death 1 April 2011.

Worked examples

Example 1 — a first encounter with Terkel Rosenqvist

Start with the simplest possible case. Write down what Terkel Rosenqvist 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 Terkel Rosenqvist 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 Terkel Rosenqvist 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 Terkel Rosenqvist

In research: Terkel Rosenqvist 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 Terkel Rosenqvist 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: Terkel Rosenqvist is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1921 births, 2011 deaths, Academic staff of the Norwegian Institute of Technology, so understanding it makes those chapters shorter.
In everyday life: Look for Terkel Rosenqvist 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.
