Kinau (crater)

Kinau (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 Kinau (crater) rather than just read about it. In short: Kinau is a small, eroded lunar impact crater that is located in the low southern latitudes of the Moon. It lies to the southeast of the crater Jacobi, and about equally far to the north-northwest of Pentland.

Key takeaways

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

Reference excerpt

Kinau is a small, eroded lunar impact crater that is located in the low southern latitudes of the Moon. It lies to the southeast of the crater Jacobi, and about equally far to the north-northwest of Pentland. It is 42 kilometers in diameter and two kilometers deep. It may be from the Pre-Nectarian period, 4.55 to 3.85 billion years ago. The northwestern rim and inner wall of this crater has been heavily damaged by impacts, and is overlaid by a pair of small, cup-shaped craters. The remainder of the rim is worn and somewhat distorted into a hexagonal shape, with several small craterlets along the rim edge. The inner walls are relatively low, and the interior floor is almost featureless except for a few tiny craterlets. There is a low rise near the midpoint that is attached to the small crater to the northwest. The crater is named after 19th century German priest, teacher and amateur astronomer Adolph Gottfried Kinau.

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 Kinau.

Notes ^ The botanist C.A. Kinau was struck from the official list of the USGS in April 2007 and replaced by the correct eponym Adolph Gottfried Kinau.

Worked examples

Example 1 — a first encounter with Kinau (crater)

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

In research: Kinau (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 Kinau (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: Kinau (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ27 quadrangle, Pre-Nectarian, so understanding it makes those chapters shorter.
In everyday life: Look for Kinau (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.
