Reference excerpt

Sofie Rostrup (née Jacobsen) (7 August 1857 - 25 January 1940) was a Danish entomologist and teacher. She has been described as the founder of agricultural entomology in Denmark. She was the first Danish woman to gain a Magisterkonferens degree in natural history, and worked as a manager of the zoological department of the Danish Farmer's Association. She was an honorary member of both the Stockholm Entomological Association and the Copenhagen Entomological Society. She was awarded the gold Medal of Merit for her services to Danish agriculture when she retired in 1927.

Career Rostrup was born on 7 August 1857 in North Jutland. Her father was a parish minister, and her mother came from a well-regarded family that included the poet Steen Steensen Blicher. Rostrup learned Latin and Greek from her father, and then initially trained as a teacher, qualifying in 1879, before attending the University of Copenhagen in 1884. When she was awarded her Magisterkonferens in natural history, majoring in zoology, in 1889 she became the first Danish woman to graduate from this degree. Rostrup has been described as the founder of agricultural entomology in Denmark. From 1896 she travelled the country to assess agricultural pest infestations and to recommend controls. This resulted in her influential 1900 treatise on the subject Vort Landbrugs Skadedyr blandt Insekter og andre lavere Dyr. From 1907 she worked with the Danish Farmer's Association on a series of agricultural experiments, and continued as an affiliated zoologist to this scheme when it was taken over by the state in 1913. In 1919 Rostrup was appointed manager of its zoological department. The Stockholm Entomological Association made her an honorary member in 1927. The Copenhagen Entomological Society, which she had joined in 1906 and regularly contributed towards, awarded Rostrup an honorary membership on her 80th birthday in 1937. When she retired in 1927, she was awarded the gold Medal of Merit for her services to Danish agriculture.

Personal life Rostrup married twice: first to zoologist Hans Jacob Hansen from 1883 to 1890, which ended in divorce, and latterly to the botanist Ove Georg Frederik Rostrup in 1892. Sofie and Ove had a single daughter, Ellen.

Worked examples

Example 1 — a first encounter with Sofie Rostrup

Start with the simplest possible case. Write down what Sofie Rostrup 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 Sofie Rostrup 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 Sofie Rostrup 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 Sofie Rostrup

In research: Sofie Rostrup 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 Sofie Rostrup 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: Sofie Rostrup is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1857 births, 1940 deaths, Danish entomologists, so understanding it makes those chapters shorter.
In everyday life: Look for Sofie Rostrup 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.
