Norman R. Legge

Norman R. Legge 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 Norman R. Legge rather than just read about it. In short: Norman Reginald Legge (20 April 1919 – 28 March 2004) was a Canadian researcher for the Shell Oil Company and pioneer of thermoplastic elastomers, Kraton in particular. Personal Legge was born on 20 April 1919 in Edmonton, Alberta, Canada.

Key takeaways

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

Reference excerpt

Norman Reginald Legge (20 April 1919 – 28 March 2004) was a Canadian researcher for the Shell Oil Company and pioneer of thermoplastic elastomers, Kraton in particular.

Personal Legge was born on 20 April 1919 in Edmonton, Alberta, Canada. He died on 28 March 2004 in Livermore, California.

Education 1942 BSC, Chemistry, University of Alberta 1943 MSC, Chemistry, University of Alberta 1945 Ph.D., McGill University, explosives research during World War II.

Career Legge worked as a research chemist for Polymer Corporation (formerly Polysar Corp.) in Sarnia, Ontario (1945-1951). Later, he moved to Kentucky Synthetic Rubber Corporation as Director of Research in Louisville. He then moved to Shell Chemical until his retirement. He was a Fellow of the American Association for the Advancement of Science and a member of the American Chemical Society, Rubber Division.

Awards and Recognitions 1987 - Charles Goodyear Medal from the ACS Rubber Division 1992 - IISRP Technical Award from the International Institute of Synthetic Rubber Producers

Worked examples

Example 1 — a first encounter with Norman R. Legge

Start with the simplest possible case. Write down what Norman R. Legge 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 Norman R. Legge 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 Norman R. Legge 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 Norman R. Legge

In research: Norman R. Legge 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 Norman R. Legge 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: Norman R. Legge is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1919 births, 2004 deaths, McGill University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Norman R. Legge 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.
