Léo Marion

Léo Marion is a chemistry 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 Léo Marion rather than just read about it. In short: Léo Edmond Marion, (March 22, 1899 – July 16, 1979) was a Canadian organic chemist and academic administrator. He was Vice-President of the National Research Council of Canada.

Key takeaways

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

Reference excerpt

Léo Edmond Marion, (March 22, 1899 – July 16, 1979) was a Canadian organic chemist and academic administrator. He was Vice-President of the National Research Council of Canada. From 1964 until 1965 he was President of the Royal Society of Canada. From 1965 until 1969, he was Dean of Faculty of Pure and Applied Science at the University of Ottawa.

Honours In 1963 he was awarded an Honorary Doctor of Science from the University of British Columbia. In 1965 he was awarded an Honorary Doctor of Science from Carleton University. In 1967 he was made a Companion of the Order of Canada. In 1968 he was awarded an Honorary Doctor of Laws from the University of Saskatchewan.

Worked examples

Example 1 — a first encounter with Léo Marion

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

In research: Léo Marion appears in chemistry 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 Léo Marion 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: Léo Marion is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1899 births, 1979 deaths, 20th-century Canadian chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Léo Marion 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.
