Poeppel Corner

Poeppel Corner 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 Poeppel Corner rather than just read about it. In short: Poeppel Corner (known as Poeppel's Corner in Queensland) at latitude 26° S and longitude 138° E is a corner of state boundaries in Australia, where the state of Queensland meets South Australia and the Northern Territory. Geography Poeppel Corner is about 174 km west of Birdsville, in the middle of the Simpson Desert.

Key takeaways

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

Reference excerpt

Poeppel Corner (known as Poeppel's Corner in Queensland) at latitude 26° S and longitude 138° E is a corner of state boundaries in Australia, where the state of Queensland meets South Australia and the Northern Territory.

Geography

Poeppel Corner is about 174 km west of Birdsville, in the middle of the Simpson Desert. New Year's Eve occurs three times each year at thirty minute intervals in Poeppel Corner (also in Cameron Corner and Surveyor Generals Corner), because it is at the intersection of three time zones.

History Augustus Poeppel, after whom the point is named, conducted a survey in the mid-1880s to find the exact location of the central Australian colonial borders. His team used camels to drag a coolibah post to mark the intersection. Originally the point was located in a salt lake, but it was found that the measuring chain used was a few centimetres too long. Another survey was conducted by Lawrence Wells, who relocated the post to its current position.

Tourism As with the other three corners it is a destination for four-wheel-drive tourists.

Heritage listing The Poeppel Corner Survey Marker is a heritage-listed site, having been added to the Queensland Heritage Register in 2012.

Worked examples

Example 1 — a first encounter with Poeppel Corner

Start with the simplest possible case. Write down what Poeppel Corner 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 Poeppel Corner 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 Poeppel Corner 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 Poeppel Corner

In research: Poeppel Corner 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 Poeppel Corner 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: Poeppel Corner is common in secondary-school and first-year university syllabi. It links to neighbouring topics Border tripoints, Borders of Queensland, Borders of South Australia, so understanding it makes those chapters shorter.
In everyday life: Look for Poeppel Corner 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.
