Roger Lass

Roger Lass 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 Lass rather than just read about it. In short: Roger Lass (born January 1, 1937) is a historical linguist, currently Emeritus Professor of Linguistics, University of Cape Town. He was previously an honorary professorial fellow at the University of Edinburgh.

Key takeaways

Roger Lass 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 Lass to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Roger Lass from memory before moving on to harder problems.

Reference excerpt

Roger Lass (born January 1, 1937) is a historical linguist, currently Emeritus Professor of Linguistics, University of Cape Town. He was previously an honorary professorial fellow at the University of Edinburgh.

Career Lass earned his PhD from Yale University in 1965 in Medieval English Language and Literature, and subsequently worked at Indiana University (1964–1971), the University of Edinburgh (1972–1982), and the University of Cape Town (1983–2002). He has done extensive work in the history of English, the motivation of sound change, and the history of linguistics. He was made an honorary professor at Edinburgh in 2014. He was the editor of the third volume of The Cambridge History of the English Language. A festschrift in honor of Lass was published in 1997 edited by Jacek Fisiak. A volume of the journal Language Sciences, entitled Collecting views on language change (Volume 24, Issues 3–4, May–July 2002, edited by Raymond Hickey) was dedicated to Lass on his sixty fifth birthday. Other essays in his honor were published in the book Motives for Language Change (CUP 2003).

Worked examples

Example 1 — a first encounter with Roger Lass

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

In research: Roger Lass 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 Lass 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 Lass is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1937 births, Academic staff of the University of Cape Town, Academics of the University of Edinburgh, so understanding it makes those chapters shorter.
In everyday life: Look for Roger Lass 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.
