Nunn (crater)

Nunn (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 Nunn (crater) rather than just read about it. In short: Nunn is a lunar impact crater that is located just beyond the eastern limb of the Moon, along the northern edge of Mare Smythii. It was named after American engineer Joseph Nunn.

Key takeaways

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

Reference excerpt

Nunn is a lunar impact crater that is located just beyond the eastern limb of the Moon, along the northern edge of Mare Smythii. It was named after American engineer Joseph Nunn. To the east of this crater is the much larger Babcock, and to the northwest is Jansky. This is a circular, bowl-shaped crater with some impact wear along the northwestern rim and to a lesser degree along the southeastern edge. The remainder of the crater perimeter is relatively free of erosion, and the edge is well-defined. The darker-hued interior floor is about half the crater diameter, and is level and almost featureless.

Worked examples

Example 1 — a first encounter with Nunn (crater)

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

In research: Nunn (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 Nunn (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: Nunn (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ14 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Nunn (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.
