Sixth principal meridian

Sixth principal meridian is a science 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 Sixth principal meridian rather than just read about it. In short: The Sixth principal meridian at 97°22′08″W extends from the baseline coincident with the north boundary of Kansas in latitude 40°N south through the state to its south boundary in latitude 37°N and north through Nebraska to the Missouri River and governs the surveys in Kansas and Nebraska; the surveys in Wyoming except those referred to the Wind River meridian and base line, which intersect in latitude 43°01′20″N an…

Key takeaways

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

Reference excerpt

The Sixth principal meridian at 97°22′08″W extends from the baseline coincident with the north boundary of Kansas in latitude 40°N south through the state to its south boundary in latitude 37°N and north through Nebraska to the Missouri River and governs the surveys in Kansas and Nebraska; the surveys in Wyoming except those referred to the Wind River meridian and base line, which intersect in latitude 43°01′20″N and longitude 108°48′40″W from Greenwich; the surveys in Colorado except those projected from the New Mexico and Ute meridians the latter intersecting its baseline in latitude 39°06′40″N and longitude 108°33′20″W from Greenwich; and the surveys in South Dakota extended or to be extended over the tract embracing the Pine Ridge and Rosebud Indian Reservations.

Worked examples

Example 1 — a first encounter with Sixth principal meridian

Start with the simplest possible case. Write down what Sixth principal meridian 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 Sixth principal meridian 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 Sixth principal meridian 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 Sixth principal meridian

In research: Sixth principal meridian 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 Sixth principal meridian 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: Sixth principal meridian is common in secondary-school and first-year university syllabi. It links to neighbouring topics Meridians (geography), Meridians and base lines of the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Sixth principal meridian 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.
