Mary (crater)

Mary (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 Mary (crater) rather than just read about it. In short: Mary is a tiny lunar impact crater in the southeastern part of the Mare Serenitatis. It is located to the northeast of the small crater Dawes, and to the west of the Montes Taurus range.

Key takeaways

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

Reference excerpt

Mary is a tiny lunar impact crater in the southeastern part of the Mare Serenitatis. It is located to the northeast of the small crater Dawes, and to the west of the Montes Taurus range. To the east-northeast of this position is the landing site of the Apollo 17 mission, in the Taurus–Littrow valley. The name of the crater was approved by the IAU in 1976, along with the nearby craters Isis, Robert, Osiris, and Jerik.

Worked examples

Example 1 — a first encounter with Mary (crater)

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

In research
Mary (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 Mary (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
Mary (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ12 quadrangle, Lunar crater stubs, so understanding it makes those chapters shorter.
In everyday life
Look for Mary (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.
