Lacus Oblivionis

Lacus Oblivionis 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 Lacus Oblivionis rather than just read about it. In short: Lacus Oblivionis (Latin oblīviōnis, "Lake of Forgetfulness") is a small lunar mare on the surface of the Moon. It is located on the far side of the Moon at 21.0° S, 168.0° W and is 50 km in diameter.

Key takeaways

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

Reference excerpt

Lacus Oblivionis (Latin oblīviōnis, "Lake of Forgetfulness") is a small lunar mare on the surface of the Moon. It is located on the far side of the Moon at 21.0° S, 168.0° W and is 50 km in diameter. The name was adopted by the IAU in 1976. The crater Mohorovičić R (satellite of Mohorovičić) lies to the northeast, and the crater Sniadecki Y (satellite of Sniadecki) lies to the southwest.

Worked examples

Example 1 — a first encounter with Lacus Oblivionis

Start with the simplest possible case. Write down what Lacus Oblivionis 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 Lacus Oblivionis 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 Lacus Oblivionis 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 Lacus Oblivionis

In research: Lacus Oblivionis 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 Lacus Oblivionis 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: Lacus Oblivionis is common in secondary-school and first-year university syllabi. It links to neighbouring topics LQ16 quadrangle, Maria on the Moon, Moon stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Lacus Oblivionis 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.
