Northwest Africa 11789

Northwest Africa 11789 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 Northwest Africa 11789 rather than just read about it. In short: NWA 11789 (also Buagaba) is a lunar meteorite that was found in the country of Mauritania. It has been broken into six fragments, which can be reassembled like a puzzle.

Key takeaways

Northwest Africa 11789 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Northwest Africa 11789 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Northwest Africa 11789 from memory before moving on to harder problems.

Reference excerpt

NWA 11789 (also Buagaba) is a lunar meteorite that was found in the country of Mauritania. It has been broken into six fragments, which can be reassembled like a puzzle. For this reason, the meteorite is also known as The Moon Puzzle.

Description The six black pieces of the meteorite fit together to form a larger meteorite, weighing 5.5 kg (12 lb). The largest fragment weighs over 2 kg (4.4 lb), and the smallest weighs about 45 g (1.6 oz). The larger pieces show a black-brown partial fusion crust, caused by the heat generated as the meteorite descended through Earth's atmosphere. The large pieces also show thumb printing. Internally, the breccia is fragmented, with white clasts of feldspar set in a black ground mass.

Ownership From 2017–2018, the meteorite was held by meteorite curator Dustin Dickens, who purchased it from an anonymous meteorite hunter in Mauritania. An auction was held by Boston-based RR Auction in October 2018, with the opening bid at $50,000. The auction closed on 19 October, with the winning bid of $612,500 awarded to Tam Chúc Pagoda complex, of Vietnam.

Worked examples

Example 1 — a first encounter with Northwest Africa 11789

Start with the simplest possible case. Write down what Northwest Africa 11789 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 Northwest Africa 11789 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 Northwest Africa 11789 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 Northwest Africa 11789

In research: Northwest Africa 11789 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 Northwest Africa 11789 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: Northwest Africa 11789 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lunar meteorites, Meteorite stubs, Meteorites found in Mauritania, so understanding it makes those chapters shorter.
In everyday life: Look for Northwest Africa 11789 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.
