Reference excerpt

Philogène Auguste Joseph Duponchel (1774 – 10 January 1846) was a French soldier and entomologist.

Life and career Philogène Auguste Joseph Duponchel was born in 1774 in Valenciennes, Nord, and died on 10 January 1846 in Paris. After studies in Douai, he joined the French Army when he was sixteen years old and took part in the campaigns of 1795 and 1796. Retiring from the army, he worked afterwards as a government administrator stationed in Paris. He was forced to retire again in 1816, aged 42 years, because of his opinions in favour of Napoleon Bonaparte. He then devoted himself to the study of insects. After twelve years of effort, Duponchel finished in 1838 L’Histoire naturelle des lépidoptères de France, co-authored with Jean Baptiste Godart. This work consists of seventeen volumes (including twelve signed by Duponchel), 7600 coloured plates and 500 "boards" (which appear under the title Iconographie des Chenilles or Iconography of the Caterpillars). The volumes were published between 1832 and 1842, and within its pages the authors describe more than four thousand species of butterflies and moths. Duponchel was one of the founders of the Société Entomologique de France and was its first treasurer. He was a very close friend of Pierre François Marie Auguste Dejean, Auguste Duméril and Pierre André Latreille. He married Marie-Joseph-Désirée Ravet (d. July 1847) and had two sons. His son Charles-Edmond Duponchel (b. 7 April 1804), studied architecture and was an accountant first class at the Ministère de la Guerre, and his son Auguste (d. October 1846) was chief medical officer of l'Ecole polytechnique. Philogène Auguste is buried in the cemetery of Montparnasse.

Worked examples

Example 1 — a first encounter with Philogène Auguste Joseph Duponchel

Start with the simplest possible case. Write down what Philogène Auguste Joseph Duponchel 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 Philogène Auguste Joseph Duponchel 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 Philogène Auguste Joseph Duponchel 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 Philogène Auguste Joseph Duponchel

In research: Philogène Auguste Joseph Duponchel 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 Philogène Auguste Joseph Duponchel 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: Philogène Auguste Joseph Duponchel is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1774 births, 1846 deaths, 18th-century French zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Philogène Auguste Joseph Duponchel 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.
