Weiss (crater)

Weiss (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 Weiss (crater) rather than just read about it. In short: Weiss is a lunar impact crater along the southern edge of the Mare Nubium. It was named after Austrian astronomer Edmund Weiss.

Key takeaways

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

Reference excerpt

Weiss is a lunar impact crater along the southern edge of the Mare Nubium. It was named after Austrian astronomer Edmund Weiss. Nearly attached to the southwest rim is the crater Cichus, and Pitatus lies just over one crater diameter to the east-northeast. To the east-southeast lies the eroded Wurzelbauer. The northern rim of this crater has been removed and the interior flooded by lava, leaving a nearly featureless surface. The southern half of the rim still survives, although it is eroded in places. This rim climbs to a height of 0.8 km above the base. The satellite crater Weiss E lies at the northern edge of the interior floor, along the surviving remnant of the rim edge. A smaller crater just to the east of Weiss E has incised the low rise along the northeastern side. The crater is marked by traces of the ray system from the prominent crater Tycho, which lies several hundred kilometers to the southeast. To the north of Weiss is the rille designated Rima Hesiodus, named after the crater Hesiodus to the northeast.

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 Weiss.

Worked examples

Example 1 — a first encounter with Weiss (crater)

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

In research: Weiss (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 Weiss (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: Weiss (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ26 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Weiss (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.
