ReKa

ReKa is a engineering 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 ReKa rather than just read about it. In short: The Residenz department store, popular under the acronym ReKa, was a department store in the style of reform architecture in Dresden-Altstadt Waisenhausstraße 16, on the corner of Prager Straße. Aryanized under the Nazis, the building was burned out in 1945 and demolished in 1950/1953.

Key takeaways

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

Reference excerpt

The Residenz department store, popular under the acronym ReKa, was a department store in the style of reform architecture in Dresden-Altstadt Waisenhausstraße 16, on the corner of Prager Straße. Aryanized under the Nazis, the building was burned out in 1945 and demolished in 1950/1953. In 1993/1995, the Karstadt department store was built on the same site.

Building history The Residenz department store, the "Reka" was considered the "first significant department store building in Dresden in glass and concrete". Built in 1912 on Prager Straße, opposite the Viktoriahaus, and designed by the Leipzig architect Emil Franz Hänsel, it was modelled on the Wertheim department store in Berlin.

The four-story building was structured by sculptural concrete pillars extending vertically over several stories with large glass surfaces in between. The second floor had bay windows with decorative ornamentation, so-called "window compartments," inserted between the pillars, reminiscent of the Dresden tradition. Above the cornice, which consisted of pearl bar, a lightly ornamented echinus, and the eaves gutter, sat arched dwarf houses in the hipped roof. The horizontal bay windows and dwarf houses visually balanced the vertical emphasis provided by the piers. The interiors were white, the ceilings were decorated with stucco and the mighty columns were covered with wood. The building had three elevators, each of which could hold ten people.

Retail spaces The department store was opened on the afternoon of October 12, 1912. The approx. 500 employees offered its assortment on four floors in 55 sales departments. Goods were delivered via a driveway in Waisenhausstraße. In keeping with the new department store trend of the time, all items were priced using price boards. While the first floor offered, among other things, haberdashery, men's goods, perfumery and stationery, the second floor offered women's fashions, corsets and shoes. The second floor offered a very wide range of goods - from sporting goods and toys to books, watches, photographic items, electrical goods and interior decoration. This floor also housed a refreshment room. Finally, the top floor housed the entire range of household items available at the time, as well as a wide-ranging food department, which included colonial produce, meat and sausages from an in-house butcher's shop, fruit and vegetables, and live fish swimming in a pool.

Other The department store appears in several books and novels. The novelist Victor Klemperer mentions in his diaries the purchase of the book Escape in the "Reka" written by the Italian anti-fascist Francesco Fausto Nitti (1899-1974) at the beginning of 1933. The painter Albert Wigand worked as a window dresser at Reka from 1930 to 1943 to earn a living. The rubble of the Residenz department store was cleared as part of the large-scale debris removal in 1950, [6] after which the area remained a green space until the start of the new department store construction of the Karstadt department store in the early 1990s. A "teacher's house" planned here in the 1960s, which would have at least touched the site, did not get beyond a foundation stone being laid in the early 1970s; this was then buried again and quietly removed in 1988.

Worked examples

Example 1 — a first encounter with ReKa

Start with the simplest possible case. Write down what ReKa claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 ReKa 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 ReKa 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 ReKa

In research
ReKa appears in engineering 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 ReKa 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
ReKa is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1910s architecture, Buildings and structures completed in 1912, Buildings and structures demolished in the 1950s, so understanding it makes those chapters shorter.
In everyday life
Look for ReKa 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.

Frequently asked questions

What is ReKa in simple terms?

The Residenz department store, popular under the acronym ReKa, was a department store in the style of reform architecture in Dresden-Altstadt Waisenhausstraße 16, on the corner of Prager Straße. Aryanized under the Nazis, the building was burned out in 1945 and demolished in 1950/1953.

Why does ReKa matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study ReKa?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
