Key takeaways

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

Reference excerpt

John Larkin Kerwin (June 22, 1924 – May 1, 2004) was a Canadian physicist. Born in Quebec City, he studied physics at St. Francis Xavier University and obtained his master's degree in physics at the Massachusetts Institute of Technology. He received his D.Sc. from Université Laval. He was Chairman of the Department of Physics from 1961 to 1967. He was the first lay Rector of Université Laval, holding this position from 1972 to 1977. From 1954 to 1955 he was the president of the Canadian Association of Physicists. From 1980 to 1989 he was President of the National Research Council of Canada and was the first president of the Canadian Space Agency and coined the term Canadarm. In 1982 he received the Gold Medal from the Canadian Council of Professional Engineers. In 1987 he was awarded the Outstanding Achievement Award of the Public Service of Canada. In 1989 he was president of the Canadian Academy of Engineering. Kerwin also served at an international level, he was president of the International Union of Pure and Applied Physics (IUPAP) from 1987–1990. In 1976, he received an honorary doctorate from Concordia University, one of 15 from various universities. In 1978 he was made an Officer of the Order of Canada and was promoted to Companion in 1980. In 1988 he was made an Officer of the National Order of Quebec. He was elected Fellow of the Royal Society of Canada and was president from 1976 to 1977. He was made an Officer of the Légion d'honneur de France. He died in Quebec City, Quebec, Canada. He was married to Maria G. Turcot and had 8 children.

Worked examples

Example 1 — a first encounter with Larkin Kerwin

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

In research: Larkin Kerwin appears in physics 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 Larkin Kerwin 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: Larkin Kerwin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1924 births, 2004 deaths, Academic staff of Université Laval, so understanding it makes those chapters shorter.
In everyday life: Look for Larkin Kerwin 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.
