Hervé Faye

Hervé Faye 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 Hervé Faye rather than just read about it. In short: Hervé Auguste Étienne Albans Faye ((1814-10-01)1 October 1814 – (1902-07-04)4 July 1902) was a French astronomer, born at Saint-Benoît-du-Sault (Indre) and educated at the École Polytechnique, which he left in 1834, before completing his course, to accept a position in the Paris Observatory to which he had been appointed on the recommendation of M. Arago.

Key takeaways

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

Reference excerpt

Hervé Auguste Étienne Albans Faye ((1814-10-01)1 October 1814 – (1902-07-04)4 July 1902) was a French astronomer, born at Saint-Benoît-du-Sault (Indre) and educated at the École Polytechnique, which he left in 1834, before completing his course, to accept a position in the Paris Observatory to which he had been appointed on the recommendation of M. Arago. It was during his time at the École Polytechnique that he developed his interest in astronomy. He studied comets, and discovered the periodic comet 4P/Faye on 22 November 1843. His discovery of "Faye's Comet" attracted worldwide attention, and won him the 1844 Lalande Prize and a membership in the French Academy of Sciences. In 1848 he became an instructor in geodesy at the Polytechnique, and in 1854 rector of the academy at Nancy and professor of astronomy in the faculty of science there. Other promotions followed in succeeding decades. He became Minister of Public Instruction in the Rochebouet cabinet in 1877, a position which he held only briefly. Faye served as the President of the Société Astronomique de France (SAF), the French astronomical society, from 1889 to 1891. He also served as president of the International Geodetic Association from 1892 to 1902. His work covered the entire field of astronomical investigation. It comprised the determination of comet periods, the measurement of parallaxes, and the study of stellar and planetary movements. He also studied the physics of the sun. He advanced several original theories on the nature and form of comets, meteors, the aurora borealis, and the sun.

Religious beliefs In his work Sur l'origine du Monde, Faye quoted the beginning of Psalm 19, "Caeli enarrant gloriam Dei" ("The heavens declare the glory of God") and stated,

We run no risk of deceiving ourselves in considering it [Superior Intelligence] the author of all things, in referring to it those splendours of the heavens which aroused our thoughts: and finally we are ready to understand and accept the traditional formula: God, Father Almighty, Creator of heaven and earth.

Publications In collaboration with Charles Galusky he translated Humboldt's Cosmos (four volumes, 1846–59), and, in addition to numerous contributions to scientific periodicals, published the following important works:

Sur les déclinaisons absolues (1850) Leçons de cosmographie (1852; second edition, 1854) Sur les cyclones solaires (1873) Cours d'astronomie de l'Ecole Polytechnique (two volumes, 1881–83) Sur l'origine du monde (1884; third edition, enlarged 1895) Nouvelle étude sur les tempêtes, cyclones, trombes, ou tornadoes (1897)

Worked examples

Example 1 — a first encounter with Hervé Faye

Start with the simplest possible case. Write down what Hervé Faye 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 Hervé Faye 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 Hervé Faye 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 Hervé Faye

In research: Hervé Faye 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 Hervé Faye 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: Hervé Faye is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1814 births, 1902 deaths, 19th-century French astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Hervé Faye 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.
