Education Douglas was awarded a Manly B.

Key takeaways

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

Reference excerpt

Robert John Wilson Douglas (1920–1979) was a Canadian geologist who made contributions in the fields of structure stratigraphy, sedimentation, and petroleum geology.

Education Douglas was awarded a Manly B. Baker Scholarship and graduated from Queen's University in geology and mineralogy. He obtained a Ph.D. degree in geology from Columbia University.

Career Douglas worked as a student assistant for the Geological Survey of Canada. He left the Survey for three years to serve as a navigator with the Royal Canadian Air Force. Douglas has contributed to our understanding of the structure of the Canadian Rocky Mountains and northern Canada. His exposition of the mechanics of bedding plane thrusts, of back-limb thrust faults and folding of the thrusts forms the basis for the later work carried out in these areas. Douglas also studied the stratigraphy of the Mississippian system in southern Alberta. These studies provided a detailed description and classification of carbonate rocks and theories on the formation of oil and gas reservoirs.

Personal life Douglas and his wife Winnifred lived in Ottawa, Ontario with their three children, Isabel, Robert and Gordon. He died of a heart attack in 1979.

Positions held 1961-1963, member of the Canadian National Committee, 6th World Petroleum Congress 1962-1964, member of the program committee of the American Association of Petroleum Geologists 1962-1965, served as associate editor of the Geological Society of America Member of the Geological Survey of Canada Committees on Stable Isotopes and Age Determination, and on Library, Stratigraphic Nomenclature Committee member on the Geology Advisory Committee of the Alberta Research Council

Worked examples

Example 1 — a first encounter with R. J. W. Douglas

Start with the simplest possible case. Write down what R. J. W. Douglas claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, 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 R. J. W. Douglas 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 R. J. W. Douglas 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 R. J. W. Douglas

In research: R. J. W. Douglas appears in earth science 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 R. J. W. Douglas 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: R. J. W. Douglas is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1920 births, 1979 deaths, 20th-century Canadian geologists, so understanding it makes those chapters shorter.
In everyday life: Look for R. J. W. Douglas 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.
