Jean Cabanis

Jean Cabanis is a astronomy 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 Jean Cabanis rather than just read about it. In short: Jean Louis Cabanis (8 March 1816 – 20 February 1906) was a German ornithologist. He worked at the bird collections of the Natural History Museum in Berlin becoming its first curator of birds in 1850.

Key takeaways

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

Reference excerpt

Jean Louis Cabanis (8 March 1816 – 20 February 1906) was a German ornithologist. He worked at the bird collections of the Natural History Museum in Berlin becoming its first curator of birds in 1850. He founded the Journal für Ornithologie in 1853.

Biography Cabanis was born in Berlin to an old Huguenot family who had moved from France. His father Benoit-Jean (1774–1838) and mother Maria Luise (1783–1849) both came from families that were in the textile industry. Little is known of his early life. He studied at the University of Berlin from 1835 to 1839, and then travelled to North America, working as a museum assistant in Carolina. He returned in 1841 with a large natural history collection. He was assistant at the Natural History Museum of Berlin (which was at the time the Berlin University Museum) and in 1850 he became the curator of birds, taking over from Martin Lichtenstein. Charles Lucien Bonaparte had offered him a position at the Jardin des Plantes but Cabanis turned it down. He founded the Journal für Ornithologie in 1853, editing it for the next forty-one years, when he was succeeded by his son-in-law Anton Reichenow. Cabanis considered the journal Naumannia, the official organ of the Deutsche Ornithologen-Gesellschaft, edited by Eduard Baldamus, as too narrow in its geographic scope and its German centricity. Cabanis married Jeanne daughter of Ambrosius Rinaldi in Berlin in 1849. They had six sons and three daughters. He died in Friedrichshagen. A number of birds are named after him, including Cabanis's bunting Emberiza cabanisi, Cabanis's spinetail Synallaxis cabanisi, azure-rumped tanager Poecilostreptus cabanisi and Cabanis's greenbul Phyllastrephus cabanisi.

Worked examples

Example 1 — a first encounter with Jean Cabanis

Start with the simplest possible case. Write down what Jean Cabanis 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 Jean Cabanis 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 Jean Cabanis 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 Jean Cabanis

In research: Jean Cabanis 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 Jean Cabanis 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: Jean Cabanis is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1816 births, 1906 deaths, Academic staff of the Humboldt University of Berlin, so understanding it makes those chapters shorter.
In everyday life: Look for Jean Cabanis 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.

Frequently asked questions

What is Jean Cabanis in simple terms?

Why does Jean Cabanis matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Jean Cabanis?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
