Robin Allan

Robin Allan is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Robin Allan rather than just read about it. In short: Robin Sutcliffe Allan (7 September 1900 – 5 July 1966) was a New Zealand geologist and university professor. The university professor William Salmond was his grandfather.

Key takeaways

Robin Allan belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Robin Allan to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Robin Allan from memory before moving on to harder problems.

Reference excerpt

Robin Sutcliffe Allan (7 September 1900 – 5 July 1966) was a New Zealand geologist and university professor. The university professor William Salmond was his grandfather. Allan was the geologist on the 1924 Chatham Islands Expedition. In 1953, Allan was awarded the Queen Elizabeth II Coronation Medal. The Allan Hills in Antarctica, mapped by the New Zealand party (1957–58) of the Commonwealth Trans-Antarctic Expedition, were named in his honour.

Worked examples

Example 1 — a first encounter with Robin Allan

Start with the simplest possible case. Write down what Robin Allan claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Robin Allan 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 Robin Allan 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 Robin Allan

In research: Robin Allan appears in astronomy 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 Robin Allan 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: Robin Allan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1900 births, 1966 deaths, 20th-century New Zealand geologists, so understanding it makes those chapters shorter.
In everyday life: Look for Robin Allan 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.

Why does Robin Allan matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Robin Allan?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
