Richardson (lunar crater)

Richardson (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 Richardson (lunar crater) rather than just read about it. In short: Richardson is a large lunar impact crater located on the Moon's far side, just behind the eastern limb. It lies to the south of the huge walled plain Harkhebi, and to the east-southeast of the crater Vestine.

Key takeaways

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

Reference excerpt

Richardson is a large lunar impact crater located on the Moon's far side, just behind the eastern limb. It lies to the south of the huge walled plain Harkhebi, and to the east-southeast of the crater Vestine. Just to the northeast is Szilard, and to the southeast is Artamonov. On the lunar geologic timescale, Richardson dates from the Pre-Nectarian period. A substantial portion of the crater is overlain by Maxwell, which lies across the rim to the southwest. The northeastern rim of Maxwell reaches the approximate midpoint of Richardson, and together with the outer rampart covers nearly half the interior floor. The remainder of the rim of Richardson is worn and eroded, with Richardson W intruding into the northwestern rim and Richardson E lying along the eastern side. The surviving interior floor of Richardson is relatively level, but marked with a number of small craterlets. The rim and interior floor is covered by a number of wispy deposits from the Giordano Bruno impact, located just to the north-northeast.

Naming Prior to formal naming in 1979 by the International Astronomical Union (IAU), this crater was known as Crater 114. The crater is named after Owen Willans Richardson (1879–1959), a British physicist who was awarded the Nobel Prize in Physics in 1928 for his pioneering work on thermionic emission. The IAU officially adopted the name "Richardson" for this crater in 1979 in recognition of his contributions to science.

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 Richardson.

Worked examples

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

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

In research: Richardson (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 Richardson (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: Richardson (lunar crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ06 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Richardson (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.
