Roger Kain

Roger Kain 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 Roger Kain rather than just read about it. In short: Roger James Peter Kain, (born 12 November 1944) is a British geographer and academic, who specialises in the history of maps. From 2010 to 2017 he was the Dean and Chief Executive of the School of Advanced Study of the University of London.

Key takeaways

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

Reference excerpt

Roger James Peter Kain, (born 12 November 1944) is a British geographer and academic, who specialises in the history of maps. From 2010 to 2017 he was the Dean and Chief Executive of the School of Advanced Study of the University of London. He was elected a Fellow of the British Academy in 1990.

Worked examples

Example 1 — a first encounter with Roger Kain

Start with the simplest possible case. Write down what Roger Kain 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 Roger Kain 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 Roger Kain 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 Roger Kain

In research: Roger Kain 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 Roger Kain 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: Roger Kain is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1944 births, Academics of the University of London, Alumni of the University of London, so understanding it makes those chapters shorter.
In everyday life: Look for Roger Kain 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.
