Saar Polygon

Saar Polygon 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 Saar Polygon rather than just read about it. In short: The Saar Polygon in Ensdorf, Saarland is a monument commemorating the coal mining industry in Saarland, which ended in June 2012. Background In Saarland, coal has been mined over several centuries.

Key takeaways

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

Reference excerpt

The Saar Polygon in Ensdorf, Saarland is a monument commemorating the coal mining industry in Saarland, which ended in June 2012.

Background In Saarland, coal has been mined over several centuries. At times, the industry was the largest employer in the region. In June 2012, the last coal mine, Bergwerk Saar, was closed. Since then, there has been no more coal mining in the Saarland. Nevertheless, the history of the coal mining industry, along with its associated traditions, is part of the region's heritage.

History of the Saar Polygon

In the setting of the coal mining industry ending, an organization called “Bergbauerbe Saar Association” was founded whose stated purpose is to promote the cultural heritage of mining with the establishment of a landmark that celebrates the contribution that the miners had in the region. In cooperation with RAG AG, which last operated the coal mining industry in Saarland through its subsidiary, RAG Deutsche Steinkohle AG, a design contest for the monument was announced. 147 designs were submitted, and the winner of the competition was the Berlin architect duo Katja Pfeiffer and Oliver Sachse. Their design for a walk-through large-scale sculpture demonstrates multiple mountain motifs as a symbol of change and is intended appear to be a gateway into the future. The meaning behind the design of the steel grid construction is the inseparability the past and future of the country and showing the traditional bond of coal, steel and energy in Saarland. Construction began in late 2015. The sculpture was completed in the spring of 2016 and was inaugurated in September 2016 and opened to the public. The approximately two million euros in construction costs were financed by the association Bergbauerbe Saar Association, RAG AG, the RAG Foundation, the Saarland state government, and donations. Donors could symbolically buy a step inside the monument for 1000 euros; at each level, a plaque with the name of the donor was placed.

Location

The Saar Polygon stands on the spoil tip of the Bergwerk Saar coal mine. This pile, with an area of about 50 hectares, rises about 150 meters above the surrounding Saar Valley. Due to its prominent position, the polygon is visible from all directions. France and Luxembourg are visible from the structure.

Description

The walk-in monument is about 30 meters high. The top of the structure is a platform, which spans approximately 35 meters long and is supported by two slanting towers with exactly 132 steps going up 25 meters. The viewing platform weighs around 60 tons. The Saar Polygon is designed to have a different shape depending on the direction in which it is viewed, such as a rectangular arch, a triangle, an inverted triangle, and an hourglass. Furthermore, it resembles the structures that are used in mines for support.

Worked examples

Example 1 — a first encounter with Saar Polygon

Start with the simplest possible case. Write down what Saar Polygon 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 Saar Polygon 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 Saar Polygon 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 Saar Polygon

In research: Saar Polygon 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 Saar Polygon 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: Saar Polygon is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2016 establishments in Germany, Coal mining, Monuments and memorials in Germany, so understanding it makes those chapters shorter.
In everyday life: Look for Saar Polygon 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.
