Larmor (crater)

Larmor (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 Larmor (crater) rather than just read about it. In short: Larmor is a crater on the Moon's far side. It is located to the east-southeast of Shayn and due north of Dante.

Key takeaways

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

Reference excerpt

Larmor is a crater on the Moon's far side. It is located to the east-southeast of Shayn and due north of Dante. It is named in honor of the physicist Joseph Larmor. The rim of Larmor is broken across by the satellite crater Larmor Z. The remaining rim is slightly worn, particularly to the southwest, and the inner wall is somewhat wider at the southern end. The wider southern inner wall displays terrace structures. Near the midpoint of the otherwise relatively level interior floor are some low hill features. The satellite crater Larmor Q, located about one and a half crater diameters to the southwest of Larmor, has a ray system. These rays lie primarily within cones to the north and southeast, which leave a 120° arc to the west which is free of ray material. The crater is fresh, with an impact melt splash pool at the bottom and lobes of melt that have flowed down the outside of the rim. The crater was named after Joseph Larmor by the IAU 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 Larmor.

Worked examples

Example 1 — a first encounter with Larmor (crater)

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

In research: Larmor (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 Larmor (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: Larmor (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 Larmor (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.
