Reference excerpt

Phineas Cook Dummer (October 28, 1797 – September 14, 1875) was the sixth mayor of Jersey City in New Jersey. He succeeded Peter Bentley, Sr. A Whig politician, he served four one-year terms from April 1844 to April 20, 1848. He was succeeded by Henry C. Taylor.

Biography Born in New Haven, Connecticut, in 1787, he served in the New York Militia during the War of 1812. Dummer married Eliza Dobbs Holt, daughter of New London, Connecticut, newspaper editor Charles Holt, on September 21, 1821, and they moved to Jersey City in 1824. Dummer joined his brother George Dummer's Jersey Glass Company on Washington Street between Essex Street and the Morris Canal in Paulus Hook (later became incorporated as Jersey City). He later obtained a patent for the manufacture of pressed glass by a process called "Dummer's scallop or coverplate." By the 1840s, the glass company was known as P.C. Dummer & Company and was selling glassware for home, decorative and commercial use. The company went out of business after the economic downturn following the Civil War. After serving as mayor, Dummer served as Chief of the Fire Department in 1850. After his company went out of business, Dummer was elected City Collector of Taxes, and afterwards appointed Deputy collector of customs of the Port of New York, by Abraham Lincoln and re-appointed under Ulysses S. Grant. He held the position until his death on September 14, 1875, in Jersey City, New Jersey.

Worked examples

Example 1 — a first encounter with Phineas C. Dummer

Start with the simplest possible case. Write down what Phineas C. Dummer 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 Phineas C. Dummer 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 Phineas C. Dummer 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 Phineas C. Dummer

In research: Phineas C. Dummer 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 Phineas C. Dummer 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: Phineas C. Dummer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1797 births, 1875 deaths, 19th-century mayors of places in New Jersey, so understanding it makes those chapters shorter.
In everyday life: Look for Phineas C. Dummer 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.
