Josep Comas i Solà

Josep Comas i Solà 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 Josep Comas i Solà rather than just read about it. In short: Josep Comas i Solà (Catalan pronunciation: [ʒuˈzɛp ˈkoməz i suˈla]; Barcelona 17 December 1868 – 2 December 1937) was a Spanish (Catalan) astronomer, discoverer of minor planets, comets, and double stars. He wrote his first astronomy notes at the age of ten, and was only fifteen when he published an article in a French specialist magazine.

Key takeaways

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

Reference excerpt

Josep Comas i Solà (Catalan pronunciation: [ʒuˈzɛp ˈkoməz i suˈla]; Barcelona 17 December 1868 – 2 December 1937) was a Spanish (Catalan) astronomer, discoverer of minor planets, comets, and double stars. He wrote his first astronomy notes at the age of ten, and was only fifteen when he published an article in a French specialist magazine. He observed planets including Mars and Saturn, measuring the rotation period of the latter. He wrote some books popularizing astronomy, and was first president of the Spanish and American Astronomical Society (Spanish: Sociedad Astrónomica de España y América; S.A.D.E.Y.A.). He discovered the periodic comet 32P/Comas Solà, and co-discovered the non-periodic comet C/1925 F1 (Shajn-Comas Solà); he is also credited by the Minor Planet Center with the discovery of 11 asteroids during 1915–1930. Comas i Solà is also credited with the discovery of the double star SOL 1. In 1905, Solà received the Prix Jules Janssen, the highest award of the Société astronomique de France, the French astronomical society. In 1908 he claimed to observe limb darkening of Saturn's moon Titan, the first evidence that the body had an atmosphere. He was the head of Fabra Observatory since it was established in 1904. The asteroids 1102 Pepita (from his nickname Pepito) and 1655 Comas Solà are named after him, as is Comas Sola crater on Mars.

Worked examples

Example 1 — a first encounter with Josep Comas i Solà

Start with the simplest possible case. Write down what Josep Comas i Solà 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 Josep Comas i Solà 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 Josep Comas i Solà 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 Josep Comas i Solà

In research: Josep Comas i Solà 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 Josep Comas i Solà 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: Josep Comas i Solà is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1868 births, 1937 deaths, 19th-century Spanish astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Josep Comas i Solà 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.
