Promontorium Deville

Promontorium Deville 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 Promontorium Deville rather than just read about it. In short: Promontorium Deville is a mountainous cape situated on the northeast margin of Mare Imbrium on the near side of the Moon. Its selenographic coordinates are 43.31° N, 1.14° E.

Key takeaways

  • Promontorium Deville belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Promontorium Deville to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Promontorium Deville from memory before moving on to harder problems.

Reference excerpt

Promontorium Deville is a mountainous cape situated on the northeast margin of Mare Imbrium on the near side of the Moon. Its selenographic coordinates are 43.31° N, 1.14° E. It is located north of Promontorium Agassiz, south of Mont Blanc, northeast of Mons Piton, and northwest of Cassini crater. Promontorium Deville is named after Charles Joseph Sainte-Claire Deville, a French meteorologist and geologist. The name of the feature was approved by the IAU in 1935.

Worked examples

Example 1 — a first encounter with Promontorium Deville

Start with the simplest possible case. Write down what Promontorium Deville 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 Promontorium Deville 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 Promontorium Deville 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 Promontorium Deville

In research
Promontorium Deville 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 Promontorium Deville 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
Promontorium Deville is common in secondary-school and first-year university syllabi. It links to neighbouring topics Moon stubs, Mountains on the Moon, so understanding it makes those chapters shorter.
In everyday life
Look for Promontorium Deville 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.
