Wiener (crater)

Wiener (crater) 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 Wiener (crater) rather than just read about it. In short: Wiener is a lunar impact crater that lies on the Moon's far side. It is located just to the southwest of the larger crater Campbell.

Key takeaways

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

Reference excerpt

Wiener is a lunar impact crater that lies on the Moon's far side. It is located just to the southwest of the larger crater Campbell. To the southwest of Wiener is the heavily worn Kurchatov. To the east along the rim of Campbell is Von Neumann. The smaller crater Pawsey lies to the north-northwest, and is partly overlain by the outer rampart of Wiener. This formation dates to the Nectarian epoch of the lunar geologic timescale. The northwestern half of the crater rim is well-formed, with some slumping and terraces along the inner walls. There is an outward protrusion in the rim along the northern side where the crater borders along Pawsey. The southern part of the crater is more irregular, with a wider, uneven inner wall and a poorly defined rim edge. The rim overlies about half of the heavily worn satellite crater Wiener K along the south-southeast. The smaller satellite crater Wiener Q lies along the southwestern rim, and the relatively fresh and polygon-shaped Wiener F is just east of the eastern rim. Within the crater, much of the interior floor is relatively level, with a clump of small ridges forming a central peak structure near the midpoint. There is a small crater to the east-northeast of these ridges, and there are several small craters near the southwestern inner wall. Prior to formal naming by the IAU in 1970, Wiener was called Crater 56.

Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Wiener.

Worked examples

Example 1 — a first encounter with Wiener (crater)

Start with the simplest possible case. Write down what Wiener (crater) 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 Wiener (crater) 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 Wiener (crater) 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 Wiener (crater)

In research: Wiener (crater) 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 Wiener (crater) 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: Wiener (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ07 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Wiener (crater) 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.
