Reference excerpt

Martin von Wahrendorff (1789 – 1861) was a Swedish diplomat and inventor. His father Anders von Wahrendorff was the owner of the gun foundry at Åker. Wahrendorff was Grand Master of Ceremonies at the Royal Court of Sweden from 1828 to 1831 In 1837 Wahrendorff applied for patent on a new breech mechanism, later known as the Wahrendorff breech. The first breech loaded Wahrendorff gun was manufactured at Åker in 1840. In the 1840s the Sardinian major Giovanni Cavalli was sent to the Åker foundry to inspect guns that the Sardinian government had ordered. The two then started experimenting with pointed elongated lead-coated projectiles fired from rifled, breech loading, guns of Wahrendorff's design. In 1854 the Swedish Army adopted three different types of smooth bored breech loaded Wahrendorff guns, in calibers from 155 to 226 mm. Wahrendorff died in 1861.

Worked examples

Example 1 — a first encounter with Martin von Wahrendorff

Start with the simplest possible case. Write down what Martin von Wahrendorff 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 Martin von Wahrendorff 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 Martin von Wahrendorff 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 Martin von Wahrendorff

In research: Martin von Wahrendorff 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 Martin von Wahrendorff 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: Martin von Wahrendorff is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1789 births, 1861 deaths, 19th-century Swedish businesspeople, so understanding it makes those chapters shorter.
In everyday life: Look for Martin von Wahrendorff 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.
