Lippmann (crater)

Lippmann (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 Lippmann (crater) rather than just read about it. In short: Lippmann is a large lunar impact crater in the southern part of the far side of the Moon and so cannot be viewed directly from the Earth. Just to the northeast is the walled plain designated Mendel, only slightly smaller than Lippmann.

Key takeaways

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

Reference excerpt

Lippmann is a large lunar impact crater in the southern part of the far side of the Moon and so cannot be viewed directly from the Earth. Just to the northeast is the walled plain designated Mendel, only slightly smaller than Lippmann. To the south-southeast lies the crater Petzval. Lippmann is named after Gabriel Lippmann (1845–1921), a Nobel laureate in physics. On the lunar geologic timescale, Lippmann dates to the Pre-Nectarian period. As with many lunar formations of this size, Lippmann has been eroded by subsequent impacts. The southeastern part of the rim has been overlain by the satellite crater Lippmann L, which in turn has become worn and eroded. The relatively fresh crater Lippmann Q lies across the southwest rim. The remaining rim has become worn and rounded, with a few surviving terrace-like features and the rim edge having lost their definition. The western and eastern sides of the crater in particular are nearly overlain by ejecta material. The interior floor is relatively level, at least in the western two-thirds, but is marked by several impacts. The most notable of these is Lippmann P, located just to the southwest of the midpoint. A short chain of small craterlets lies along the southern part of the floor. The remainder is marked by a few small craterlets and pitted by tiny craters. The terrain to the north and east of this crater are streaked with features that are radial to the huge Mare Orientale impact basin to the northeast. Also, Lippmann lies to the southwest of the Mendel-Rydberg Basin, a 630 km wide impact basin of Nectarian age (older than Orientale), and it is on the southeast margin of the Pre-Nectarian South Pole-Aitken Basin.

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 Lippmann.

Worked examples

Example 1 — a first encounter with Lippmann (crater)

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

In research: Lippmann (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 Lippmann (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: Lippmann (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ25 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Lippmann (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.
