Lamé (crater)

Lamé (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 Lamé (crater) rather than just read about it. In short: Lamé is a lunar impact crater located astride the northeast rim of the crater Langrenus, to the east of Mare Fecunditatis. The eastern crater rim appears overlaid by a series of overlapping craters that form an intermittent chain flowing nearly a hundred kilometers to the south.

Key takeaways

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

Reference excerpt

Lamé is a lunar impact crater located astride the northeast rim of the crater Langrenus, to the east of Mare Fecunditatis. The eastern crater rim appears overlaid by a series of overlapping craters that form an intermittent chain flowing nearly a hundred kilometers to the south. The crater rim protrudes only slightly above the surrounding terrain, but it has a significant rampart where the rim lies within Vendelinus. In the middle of the floor is a slight ridge, forming a central peak. This crater is named after French mathematician Gabriel Lamé (1795–1870). On some older maps this crater was called Smith. It was previously designated Vendelinus C before being renamed by the IAU.

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 Lamé.

Worked examples

Example 1 — a first encounter with Lamé (crater)

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

In research
Lamé (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 Lamé (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
Lamé (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ21 quadrangle, so understanding it makes those chapters shorter.
In everyday life
Look for Lamé (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.
