Reference excerpt

Johann Julius Walbaum (30 June 1724 – 21 August 1799) was a German physician, naturalist and fauna taxonomist.

Works Walbaum was from Greifswald. As an ichthyologist, he was the first to describe many previously unknown fish species from remote parts of the globe, such as the Great Barracuda (Sphyraena barracuda), the Chum salmon (Oncorhynchus keta) from the Kamchatka River in Siberia, and the curimatá-pacú (Prochilodus marggravii) from the São Francisco River in Brazil. Walbaum was one of the first to observe gloves as a preventative against infection in medical surgery. As early as 1767, he used gloves made from sheep intestines for vaginal exams.

Legacy The Natural History Museum in Lübeck, opened in 1893, was based on Walbaum's extensive scientific collection. The museum's collection was, however, destroyed during the Bombing of Lübeck.

Worked examples

Example 1 — a first encounter with Johann Julius Walbaum

Start with the simplest possible case. Write down what Johann Julius Walbaum 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 Johann Julius Walbaum 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 Johann Julius Walbaum 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 Johann Julius Walbaum

In research: Johann Julius Walbaum 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 Johann Julius Walbaum 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: Johann Julius Walbaum is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1724 births, 1799 deaths, 18th-century German male writers, so understanding it makes those chapters shorter.
In everyday life: Look for Johann Julius Walbaum 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.
