Slipher (lunar crater)

Slipher (lunar 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 Slipher (lunar crater) rather than just read about it. In short: Slipher is a lunar impact crater, that is located in the northern latitudes on the far side of the Moon. The crater overlies the southwestern outer rim of the much larger walled plain D'Alembert, and it occupies a portion of the interior floor of D'Alembert.

Key takeaways

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

Reference excerpt

Slipher is a lunar impact crater, that is located in the northern latitudes on the far side of the Moon. The crater overlies the southwestern outer rim of the much larger walled plain D'Alembert, and it occupies a portion of the interior floor of D'Alembert. To the south-southeast is the crater Langevin. This formation dates to the Late Imbrian epoch of the lunar geologic timescale. Because it overlies D'Alembert, Slipher is a younger formation and it has undergone much less erosion. The rim is circular but has a somewhat irregular edge. The rim is jumbled and irregular where it intersects D'Alembert. Overlapping the western rim and inner walls of Slipher is the smaller Slipher S, a fresh feature with a sharp-edged outer rim. The infrared spectrum of pure crystalline plagioclase has been identified on the east wall. The interior floor of Slipher is somewhat uneven except in the northeast, and there is a cluster of low central ridges near the midpoint. A distinct lobate scarp, located near the south wall of the crater, was imaged by Lunar Reconnaissance Orbiter. The scarp is a result of the cooling of the moon and resulting compression of the surface. The crater was formally named by the IAU in 1970 after American astronomers Earl Slipher and Vesto Slipher.

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 Slipher.

Worked examples

Example 1 — a first encounter with Slipher (lunar crater)

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

In research: Slipher (lunar 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 Slipher (lunar 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: Slipher (lunar 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 Slipher (lunar 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.
