Protagoras (crater)

Protagoras (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 Protagoras (crater) rather than just read about it. In short: Protagoras is a lunar impact crater that is located on the Mare Frigoris in the northern part of the Moon. To the north-northwest is the slightly larger crater Archytas, and to the southeast is the prominent Aristoteles.

Key takeaways

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

Reference excerpt

Protagoras is a lunar impact crater that is located on the Mare Frigoris in the northern part of the Moon. To the north-northwest is the slightly larger crater Archytas, and to the southeast is the prominent Aristoteles. The rim of Protagoras is circular and rises above the surrounding flat terrain, although the rim dips down along the southwestern edge. The interior floor contains a few light markings but no formations of interest. There is an area of rough terrain just to the east of this crater, but the surroundings are otherwise level with only a few small craters in the vicinity. The crater is named for the Greek sophist Protagoras of Abdera. Protagoras is a crater of Lower (Early) Imbrian age.

Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint closest to Protagoras.

Worked examples

Example 1 — a first encounter with Protagoras (crater)

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

In research
Protagoras (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 Protagoras (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
Protagoras (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ05 quadrangle, so understanding it makes those chapters shorter.
In everyday life
Look for Protagoras (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.
