Michel Giacobini

Michel Giacobini 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 Michel Giacobini rather than just read about it. In short: Michel Giacobini (1873–1938) was a French astronomer. He discovered a number of comets, including 21P/Giacobini-Zinner (parent body of the Giacobinids meteor shower), 41P/Tuttle-Giacobini-Kresak, and 205P/Giacobini.

Key takeaways

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

Reference excerpt

Michel Giacobini (1873–1938) was a French astronomer. He discovered a number of comets, including 21P/Giacobini-Zinner (parent body of the Giacobinids meteor shower), 41P/Tuttle-Giacobini-Kresak, and 205P/Giacobini. The latter he had discovered at Nice on 4 September 1896, but it was not seen on its return, a little less than 7 years later, and was considered a lost comet and consequently designated D/1896 R2. On 10 September 2008, amateur supernova hunters Koichi Itagaki and Hiroshi Kaneda rediscovered it, on its seventeenth return. He won the Lalande Prize in 1900 and worked at the Nice Observatory until 1910, when he requested a transfer to the Paris Observatory. He was awarded the Valz Prize by the French Academy of Sciences in both 1905 and 1908. In 1903, Giacobinin received the Prix Jules Janssen, the highest award of the Société astronomique de France, the French astronomical society. He volunteered for military service in World War I and suffered the effects of poison gas. He recovered and resumed his astronomical activities after the war.

Worked examples

Example 1 — a first encounter with Michel Giacobini

Start with the simplest possible case. Write down what Michel Giacobini 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 Michel Giacobini 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 Michel Giacobini 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 Michel Giacobini

In research: Michel Giacobini 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 Michel Giacobini 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: Michel Giacobini is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1873 births, 1938 deaths, 20th-century French astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Michel Giacobini 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.
