Reference excerpt

William H. Casselman (July 26, 1868 – July 2, 1941) was an Ontario farmer and political figure. He represented Dundas as a United Farmers of Ontario member from 1919 to 1923. He was born in Chesterville, Ontario, the son of James C. Casselman, and was educated in Chesterville and Morrisburg. In 1897, he married Flora Carlyle. He was defeated in the 1923 general election by Aaron Sweet. From 1931 until his death, he served as Reeve of the Village of Chesterville. He died in an accident on the farm while unloading hay. His half-brother Orren D. Casselman served in the House of Commons.

Worked examples

Example 1 — a first encounter with William H. Casselman

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

In research: William H. Casselman appears in 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 William H. Casselman 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: William H. Casselman is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1868 births, 1941 deaths, 20th-century mayors of places in Ontario, so understanding it makes those chapters shorter.
In everyday life: Look for William H. Casselman 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.
