Wexler (crater)

Wexler (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 Wexler (crater) rather than just read about it. In short: Wexler is a lunar impact crater that lies across the south-southeast limb of the Moon. In this location not much detail about the formation can be discerned from the Earth, and it must be viewed from orbit to see most of the structure.

Key takeaways

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

Reference excerpt

Wexler is a lunar impact crater that lies across the south-southeast limb of the Moon. In this location not much detail about the formation can be discerned from the Earth, and it must be viewed from orbit to see most of the structure. It lies about a hundred kilometers northwards of the larger crater Hale, and south-southeast of Petrov. The rim of this crater retains much of its original structure, although the features have become softened and worn in comparison to the younger Hale. The rim has a polygonal appearance along most of the perimeter, and traces of terraces can still be seen along sections of the inner wall. There is a small crater across the northwest rim, but otherwise the formation is not significantly marked by impacts. The interior floor is relatively flat and level, with a central peak near the midpoint. There is the ghostly remnant of a crater to the northeast of the middle peak. Within a half crater diameter to the north and east is a wide, valley-like rift in the surface. The narrow end of this cut is located to the east of Wexler, and from there it follows a nearly straight, widening course to the northeast, before opening wide towards the northwest to the north of Wexler. This crater is named after American meteorologist Harry Wexler (1911-1962). Its designation was formally adopted by the International Astronomical Union in 1970.

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 Wexler.

Worked examples

Example 1 — a first encounter with Wexler (crater)

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

In research: Wexler (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 Wexler (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: Wexler (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ30 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Wexler (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.
