Honoré Jacquinot

Honoré Jacquinot 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 Honoré Jacquinot rather than just read about it. In short: Honoré Jacquinot (French pronunciation: [ɔnɔʁe ʒakino]; 1 August 1815 in Moulins-Engilbert – 22 May 1887 in Nevers) was a French surgeon and zoologist. Jacquinot was the younger brother of the naval officer Charles Hector Jacquinot, and sailed with him as a surgeon and naturalist on La Zelée on Dumont d'Urville's Astrolabe expedition (1837–1840).

Key takeaways

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

Reference excerpt

Honoré Jacquinot (French pronunciation: [ɔnɔʁe ʒakino]; 1 August 1815 in Moulins-Engilbert – 22 May 1887 in Nevers) was a French surgeon and zoologist. Jacquinot was the younger brother of the naval officer Charles Hector Jacquinot, and sailed with him as a surgeon and naturalist on La Zelée on Dumont d'Urville's Astrolabe expedition (1837–1840). In 1837 with J. B. Hombron, while en route to the Antarctic aboard the Astrolabe and anchored off the coast of New Zealand, he was able to describe and illustrate 15 species of molluscs found in those waters, plus several species of fish and crustacea.

Worked examples

Example 1 — a first encounter with Honoré Jacquinot

Start with the simplest possible case. Write down what Honoré Jacquinot 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 Honoré Jacquinot 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 Honoré Jacquinot 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 Honoré Jacquinot

In research: Honoré Jacquinot 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 Honoré Jacquinot 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: Honoré Jacquinot is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1815 births, 1887 deaths, 19th-century French zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Honoré Jacquinot 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.
