Pike's Mile Markers

Pike's Mile Markers is a engineering 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 Pike's Mile Markers rather than just read about it. In short: Pike's Mile Markers are a series of twelve stone mileposts along United States Route 1 in Robbinston and Calais in far eastern Washington County, Maine. The stones were placed by James Shepherd Pike, owner of The Mansion House which stands near the 12-mile mark.

Key takeaways

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

Reference excerpt

Pike's Mile Markers are a series of twelve stone mileposts along United States Route 1 in Robbinston and Calais in far eastern Washington County, Maine. The stones were placed by James Shepherd Pike, owner of The Mansion House which stands near the 12-mile mark. The measure the distance from his house to the center of Calais, and were supposedly used by Pike to assess the quality of his horses. The markers, unique in the state of Maine, were listed on the National Register of Historic Places in 1995.

History James Shepherd Pike (1811–82) was born in Calais, and achieved a nationwide reputation as a journalist with a strong anti-slavery voice prior to the American Civil War. During the war he served as United States Ambassador to the Netherlands. Upon his return from that posting, he purchased the Mansion House, a large Federal-style mansion in Robbinston, where he lived in semi-retirement. He continued to write on subjects related to African-American civil rights, but became bitterly opposed to the corruption and mismanagement of the Reconstruction Era. Pike is said to have carefully measured the route from his house to Calais, and then placed these stones sometime between his purchase of the Mansion House and his death in 1882. He is also said to have used them as a means to gauge the performance of his horses.

List of markers There are twelve markers in all, of which eleven are those originally placed by Pike. Marker #6 was destroyed during road works on US 1 shortly after World War II, and was replaced by a similar marker fashioned out of red granite; Pike's original markers are all gray granite, with inscriptions painted in red on a white background. All of the markers are located on the east side of US 1.

Worked examples

Example 1 — a first encounter with Pike's Mile Markers

Start with the simplest possible case. Write down what Pike's Mile Markers 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 Pike's Mile Markers 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 Pike's Mile Markers 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 Pike's Mile Markers

In research: Pike's Mile Markers 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 Pike's Mile Markers 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: Pike's Mile Markers is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1866 establishments in Maine, Buildings and structures completed in 1866, Historic districts on the National Register of Historic Places in Maine, so understanding it makes those chapters shorter.
In everyday life: Look for Pike's Mile Markers 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.
