Stevinus (crater)

Stevinus (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 Stevinus (crater) rather than just read about it. In short: Stevinus is a lunar impact crater located in the southeast part of the Moon. To the southeast is the large crater Furnerius.

Key takeaways

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

Reference excerpt

Stevinus is a lunar impact crater located in the southeast part of the Moon. To the southeast is the large crater Furnerius. Just to the northeast is Snellius and the Vallis Snellius crater valley. To the west-northwest lies Reichenbach. To the west-northwest of Stevinus is the tiny crater Stevinus A, a feature that possesses a small ray system and a displays a high albedo. Stevinus has a high inner wall and a central peak at the midpoint of the interior floor. The inner walls are slumped, so that the side slopes down sharply, then more gradually. There are several small ridges on the floor, in addition to the peak. The spectra of this peak fits an olivine-bearing gabbroic norite mineralogy, which originated from a depth of 7.4 to 11.6 km. Due to its ray system, Stevinus is mapped as part of the Copernican System on the lunar geologic timescale. It is named for Simon Stevin, a 16th-century Belgian mathematician and engineer.

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 Stevinus.

Worked examples

Example 1 — a first encounter with Stevinus (crater)

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

In research: Stevinus (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 Stevinus (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: Stevinus (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ27 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Stevinus (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.
