Reference excerpt

Lionel Jack Dumbleton (1905 – 25 September 1976) was a New Zealand entomologist. He was born in Hampden, New Zealand and was a founding member of the Entomological Society of New Zealand. Dumbleton was one of the entomologists studying insects on the 1949 New Zealand American Fiordland Expedition. One of his most remarkable biological discoveries was a new genus of caddis-fly-like primitive moths that he described as Agathiphaga and which has been subsequently raised to superfamily level as the second most primitive known living lineage of moths, Agathiphagoidea. Shortly before retiring, Dumbleton survived a stroke. In 1998 a new genus of hepialid moths was named Dumbletonius in his honour, and Hort Research has a building in Auckland named after him.

Worked examples

Example 1 — a first encounter with Lionel Jack Dumbleton

Start with the simplest possible case. Write down what Lionel Jack Dumbleton claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Lionel Jack Dumbleton 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 Lionel Jack Dumbleton 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 Lionel Jack Dumbleton

In research: Lionel Jack Dumbleton appears in biology 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 Lionel Jack Dumbleton 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: Lionel Jack Dumbleton is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1905 births, 1976 deaths, 20th-century New Zealand zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Lionel Jack Dumbleton 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.
