Kidinnu (crater)

Kidinnu (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 Kidinnu (crater) rather than just read about it. In short: Kidinnu is an impact crater on the Moon's far side. It lies to the south of the crater H.

Key takeaways

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

Reference excerpt

Kidinnu is an impact crater on the Moon's far side. It lies to the south of the crater H. G. Wells and to the southeast of Cantor. This is a somewhat unevenly formed crater with an outer rim that forms a rounded polygon. The inner wall varies in width, with the narrowest stretch along the outward-bulging northeast. There are no craters of note along the rim or within the interior. The interior floor is uneven, with a central ridge that runs to the southern edge. Prior to formal naming by the IAU in 1970, Kidinnu was called Crater 122.

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 Kidinnu.

Worked examples

Example 1 — a first encounter with Kidinnu (crater)

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

In research: Kidinnu (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 Kidinnu (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: Kidinnu (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 Kidinnu (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.
