Secretaire en portefeuille

Secretaire en portefeuille 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 Secretaire en portefeuille rather than just read about it. In short: The secretaire en portefeuille is an antique desk form which is usually mounted on rollers at the end of four jutting legs. The legs in turn support what looks like an oversize vertically mounted wooden pizza box.

Key takeaways

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

Reference excerpt

The secretaire en portefeuille is an antique desk form which is usually mounted on rollers at the end of four jutting legs. The legs in turn support what looks like an oversize vertically mounted wooden pizza box. This is a cabinet a few inches thick, with barely enough space in it for the raised desktop surface and a few pens and sheets of paper disposed vertically. It is also called a "Billet doux". The secretaire en portefeuille is much like a fall front desk which has been reduced in depth to a bare minimum. Like the fall front desk and the secretary desk the secretaire en portefeuille's desktop lifts up to cover internal areas and must thus be cleared of all work before closing up. By its mobile nature and its relatively light weight it was sometimes used as a fire screen desk. It was also sometimes known by that name. Its name comes from the French word for wallet: portefeuille. This is probably because it has the same proportions as many kinds of wallets and it opens up a bit like some of them. Modern day cabinet makers and furniture designers have sometimes created contemporary versions of the secretaire en portefeuille, eschewing the florid designs of the antique ones.

Worked examples

Example 1 — a first encounter with Secretaire en portefeuille

Start with the simplest possible case. Write down what Secretaire en portefeuille 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 Secretaire en portefeuille 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 Secretaire en portefeuille 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 Secretaire en portefeuille

In research
Secretaire en portefeuille 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 Secretaire en portefeuille 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
Secretaire en portefeuille is common in secondary-school and first-year university syllabi. It links to neighbouring topics Desks, History of furniture, so understanding it makes those chapters shorter.
In everyday life
Look for Secretaire en portefeuille 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.
