Indian meridian

Indian 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 Indian meridian rather than just read about it. In short: The Indian meridian, in longitude 97° 14′ 30″ west from Greenwich, extends from Red River to the south boundary of Kansas, and, with the base line in latitude 34° 30′ north, governs the surveys in Oklahoma east of 100° west longitude from Greenwich (all of Oklahoma except the Oklahoma panhandle). This line was chosen arbitrarily as part of the land survey of 1870 conducted by E.

Key takeaways

Indian 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 Indian meridian to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Indian meridian from memory before moving on to harder problems.

Reference excerpt

The Indian meridian, in longitude 97° 14′ 30″ west from Greenwich, extends from Red River to the south boundary of Kansas, and, with the base line in latitude 34° 30′ north, governs the surveys in Oklahoma east of 100° west longitude from Greenwich (all of Oklahoma except the Oklahoma panhandle). This line was chosen arbitrarily as part of the land survey of 1870 conducted by E. N. Darling and Thomas H. Barrett, at an arbitrary point about one mile south of Fort Arbuckle (about six miles west of present Davis, Oklahoma). From this initial point, the north–south line was designated as the Indian meridian and the East–West line was designated as the Indian baseline. The Indian Meridian initial point is listed in the National Register of Historic Places with ID #70000533.

Worked examples

Example 1 — a first encounter with Indian meridian

Start with the simplest possible case. Write down what Indian 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 Indian 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 Indian 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 Indian meridian

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