Guillaume (crater)

Guillaume (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 Guillaume (crater) rather than just read about it. In short: Guillaume is an old lunar impact crater on the Moon's northern hemisphere, and is located on the far side relative to the Earth. It lies just to the southeast of the slightly larger crater Perkin.

Key takeaways

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

Reference excerpt

Guillaume is an old lunar impact crater on the Moon's northern hemisphere, and is located on the far side relative to the Earth. It lies just to the southeast of the slightly larger crater Perkin. This is a worn and eroded formation, with features that have been softened and rounded over time. A cluster of small craters covers most of the northeastern rim. Several small craterlets lie along the edge to the south and west. The bowl-like interior is nearly featureless, with only a few small craterlets to mark the surface. Prior to formal naming by the IAU in 1979, Guillaume was called Crater 73.

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 Guillaume.

Worked examples

Example 1 — a first encounter with Guillaume (crater)

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

In research: Guillaume (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 Guillaume (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: Guillaume (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ02 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Guillaume (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.
