Reference excerpt

Colonel Lacey Robert Johnson (1855–1915) was a Canadian Pacific Railway pioneer.

Early life and education Lacey Johnson was born 22 June 1855, in Abingdon-on-Thames, the son of James Lacey Johnson, draper, of Market Place, Abingdon, Oxfordshire, England. He was educated at Abingdon School from 1865 to 1868.

Career He entered the Great Western Railway works at Swindon (1870), then was chief engineer of paper mills and worked at Woolwich Royal Arsenal (1875). He first went to India, and then to Canada, where he joined the Grand Trunk Railway (1882) and became chief engineer to the Canadian Pacific Railway. He was photographed in the Press with Lord Strathcona driving the last spike at Craigellachie (November 1885) for the CPR. He was general superintendent of shipping and superintendent of rolling stock at Montreal (1901). A member of the Canadian Society of Civil Engineers, he became president of the Canadian Railway Club, Squire of the Order of St John of Jerusalem and Grand Master of the Grand Lodge of British Columbia and the Yukon (1895–96). Lacey Johnson served in the First World War as Colonel, Canadian Heavy Artillery and was responsible for the munitions output of Canada. He died in Montreal in 1915.

Worked examples

Example 1 — a first encounter with Lacey Robert Johnson

Start with the simplest possible case. Write down what Lacey Robert Johnson claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Lacey Robert Johnson 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 Lacey Robert Johnson 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 Lacey Robert Johnson

In research: Lacey Robert Johnson appears in engineering 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 Lacey Robert Johnson 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: Lacey Robert Johnson is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1855 births, 1915 deaths, 19th-century American businesspeople, so understanding it makes those chapters shorter.
In everyday life: Look for Lacey Robert Johnson 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.
