Guy Reiss

Guy Reiss 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 Guy Reiss rather than just read about it. In short: Guy Reiss (1904–1964) was a French astronomer and discoverer of five asteroids, who worked at the Algiers Observatory in Algiers, North Africa, during the 1930s and later at the Nice Observatory in southeastern France. Among his discoveries made between 1931 and 1935 at Algiers, he named the minor planets 1237 Geneviève, 1300 Marcelle and 1376 Michelle after his three daughters.

Key takeaways

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

Reference excerpt

Guy Reiss (1904–1964) was a French astronomer and discoverer of five asteroids, who worked at the Algiers Observatory in Algiers, North Africa, during the 1930s and later at the Nice Observatory in southeastern France. Among his discoveries made between 1931 and 1935 at Algiers, he named the minor planets 1237 Geneviève, 1300 Marcelle and 1376 Michelle after his three daughters. His first discovery, 1213 Algeria, was named in honour of the North African country, location of the discovering observatory, and a French colony at the time. The asteroid 1299 Mertona was named after English astronomer Gerald Merton, who became president of the British Astronomical Association in the 1950s. In 1935, he received the Damoiseau-Prize together with André Patry from the French Academy of Sciences for the whole of their work. The minor planet 1577 Reiss, discovered by his college astronomer Louis Boyer at Algiers Observatory in the 1940s, was named in his honour.

Worked examples

Example 1 — a first encounter with Guy Reiss

Start with the simplest possible case. Write down what Guy Reiss 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 Guy Reiss 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 Guy Reiss 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 Guy Reiss

In research
Guy Reiss 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 Guy Reiss 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
Guy Reiss is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1904 births, 1964 deaths, 20th-century French astronomers, so understanding it makes those chapters shorter.
In everyday life
Look for Guy Reiss 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.

Why does Guy Reiss 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.
