Roger Gaudry

Roger Gaudry 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 Gaudry rather than just read about it. In short: Roger Gaudry, (December 15, 1913 – October 7, 2001) was a Canadian chemist, businessman, corporate director, and rector of the Université de Montréal. Early life and education Born in Quebec City, Quebec, he received a Bachelor of Science (B.Sc.) in chemistry in 1937 and a Doctor of Science (D.Sc.) in chemistry in 1940 from Université Laval.

Key takeaways

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

Reference excerpt

Roger Gaudry, (December 15, 1913 – October 7, 2001) was a Canadian chemist, businessman, corporate director, and rector of the Université de Montréal.

Early life and education Born in Quebec City, Quebec, he received a Bachelor of Science (B.Sc.) in chemistry in 1937 and a Doctor of Science (D.Sc.) in chemistry in 1940 from Université Laval. A Rhodes scholar, he attended the University of Oxford from 1937 to 1939.

Career From 1940 to 1945, he was assistant professor of chemistry in the Faculty of Medicine at Université Laval. He was appointed associate professor in 1945 and professor in 1950. In 1954, he became assistant director of research at Ayerst, McKenna & Harrison Ltd. in Montréal From 1957 to 1965, he was director and vice-president from 1963 to 1965. From 1965 to 1975, he served as the rector of the Université de Montréal. He was a member of the board of directors of the following companies: Connaught Laboratories Ltd., CDC Life Sciences Inc., Bank of Montreal, Alcan, Hoechst Canada, S.K.W. Canada Ltd., Bio-Recherche Ltée, Corby Distilleries Ltd, and St. Lawrence Starch Co. Ltd. From 1983 to 1995, he was president of the Fondation Jules et Paul-Emile Léger, a Canadian charity which supports groups that help restore human dignity to those who have been rejected by society. After his death in 2001, he was entombed at the Notre Dame des Neiges Cemetery in Montreal.

Honours In 1954, he was made a Fellow of the Royal Society of Canada. In 1968, he was made a Companion of the Order of Canada. In 1980, he received an honorary doctorate from Concordia University. In 1992, he was made a Grand Officer of the National Order of Quebec. In 1996, he became the recipient of the José Vasconcelos World Award of Education In 2003, the main pavilion at Université de Montréal, Roger-Gaudry Building, was renamed in his honor.

Worked examples

Example 1 — a first encounter with Roger Gaudry

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

In research: Roger Gaudry 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 Gaudry 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 Gaudry is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1913 births, 2001 deaths, Burials at Notre Dame des Neiges Cemetery, so understanding it makes those chapters shorter.
In everyday life: Look for Roger Gaudry 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.
