Accomplishments He was aboard the barge Louqsor, which was set to bring the Luxor Obelisk to the Place de la Concorde in Paris.

Key takeaways

Justin-Pascal Angelin belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Justin-Pascal Angelin to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Justin-Pascal Angelin (born 17 May 1795) was a French Naval surgeon born in Marseille.

Accomplishments He was aboard the barge Louqsor, which was set to bring the Luxor Obelisk to the Place de la Concorde in Paris. While stationed in Egypt, Angelin observed a lethal cholera epidemic that claimed the lives of 150,000 of the country's 3.5 million residents in a matter of two months. In 1833, he published Expédition du Louxor ou relation de la campagne faite dans la Thébaide pour en rapporter l'obélisque occidental de Thèbes about his experiences on the mission, and the following year he pursued his doctorate in medicine at the University of Paris, where he wrote his thesis about the cholera outbreak that had occurred in Luxor. In 1838, Angelin authored another piece entitled Mémoire sur l'épidémie de fièvre jaune qui a régné en 1838 à la Guadeloupe, et particulièrement à la Pointe-à-Pitre.

Worked examples

Example 1 — a first encounter with Justin-Pascal Angelin

Start with the simplest possible case. Write down what Justin-Pascal Angelin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Justin-Pascal Angelin 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 Justin-Pascal Angelin 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 Justin-Pascal Angelin

In research: Justin-Pascal Angelin appears in astronomy 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 Justin-Pascal Angelin 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: Justin-Pascal Angelin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1795 births, French surgeons, Naval surgeons, so understanding it makes those chapters shorter.
In everyday life: Look for Justin-Pascal Angelin 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.
