Passage Choiseul

Passage Choiseul 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 Passage Choiseul rather than just read about it. In short: The Passage Choiseul (French pronunciation: [pasaʒ ʃwazœl]) is one of the covered passages of Paris, located in the 2nd arrondissement. It is the continuation of the Rue de Choiseul.

Key takeaways

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

Reference excerpt

The Passage Choiseul (French pronunciation: [pasaʒ ʃwazœl]) is one of the covered passages of Paris, located in the 2nd arrondissement. It is the continuation of the Rue de Choiseul.

History The Passage Choiseul is on a site previously occupied by four hôtels particuliers, acquired by the Mallet Bank for a real-estate development that included the Opéra-Comique's nearby Salle Ventadour. The passage was built between 1826 and 1827, first to the designs of the architect François Mazois, then Antoine Tavernier. Mazois died before the building was complete, and Tavernier completed the work. The author Louis-Ferdinand Céline lived there as a child in the early 20th century. The Passage Choiseul is mentioned in two of his novels: Journey to the End of the Night and Death on the Installment Plan. Céline described it as having gas lamps that "stank as badly as the stagnant air", and the aroma of "dogs urine" in the passage. In 1907, the glass roof was replaced (although its ironwork dates from 1891). The passage later fell into disrepair. In the 1970s, visitation increased when Kenzo opened a boutique in the passage. They have since relocated to the Place des Victoires.

Today The Passage Choiseul is a shopping and food area. It has restaurants, clothing stores, book stores, jewellery shops, art galleries, art supply shops and a hair stylist. The entrance to the Théâtre des Bouffes-Parisiens is located in the passage. The ground floor is mainly retail and the upper floors are primarily residential. It is the longest covered passage in the city, at 190 meters long and 3.7 meters wide. In 2012, renovations and restoration were begun under Jean Frédéric Grevet. It is a registered historic monument in France.

Location

It is just west of the Galerie Vivienne on the Rue des Petits-Champs in the 2nd arrondissement.

Worked examples

Example 1 — a first encounter with Passage Choiseul

Start with the simplest possible case. Write down what Passage Choiseul 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 Passage Choiseul 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 Passage Choiseul 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 Passage Choiseul

In research: Passage Choiseul 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 Passage Choiseul 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: Passage Choiseul is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1827 establishments in France, Buildings and structures completed in 1827, Buildings and structures in the 2nd arrondissement of Paris, so understanding it makes those chapters shorter.
In everyday life: Look for Passage Choiseul 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.
