Jacob ben Isaac Corsono

Jacob ben Isaac Corsono 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 Jacob ben Isaac Corsono rather than just read about it. In short: Jacob ben Isaac al-Corsono or Carsono or Carsi (also Abu Ishaq Ya'qub ibn Ishaq ibn Ya'qub, known as Ibn al-Qursunuh) was a Spanish astronomer of the fourteenth century. He was commissioned by King Peter IV of Aragon to translate from Catalan into Hebrew the astronomical tables known as The Tables of Don Pedro, which, at Don Pedro's command, had been begun by Maestre Piero Gilebert, and finished by Gilebert's pupil…

Key takeaways

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

Reference excerpt

Jacob ben Isaac al-Corsono or Carsono or Carsi (also Abu Ishaq Ya'qub ibn Ishaq ibn Ya'qub, known as Ibn al-Qursunuh) was a Spanish astronomer of the fourteenth century. He was commissioned by King Peter IV of Aragon to translate from Catalan into Hebrew the astronomical tables known as The Tables of Don Pedro, which, at Don Pedro's command, had been begun by Maestre Piero Gilebert, and finished by Gilebert's pupil, Dalmacio de Planis. About 1376 Carsono wrote at Seville a treatise in Arabic on the astrolabe. This he himself translated into Hebrew at Barcelona in 1378. Chayyim ibn Musa ascribes kabbalistic miracles to Carsono.

This article incorporates text from a publication now in the public domain: Richard Gottheil and Meyer Kayserling (1901–1906). "Carsono, Corsono". In Singer, Isidore; et al. (eds.). The Jewish Encyclopedia. New York: Funk & Wagnalls.

Worked examples

Example 1 — a first encounter with Jacob ben Isaac Corsono

Start with the simplest possible case. Write down what Jacob ben Isaac Corsono 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 Jacob ben Isaac Corsono 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 Jacob ben Isaac Corsono 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 Jacob ben Isaac Corsono

In research
Jacob ben Isaac Corsono 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 Jacob ben Isaac Corsono 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
Jacob ben Isaac Corsono is common in secondary-school and first-year university syllabi. It links to neighbouring topics 14th-century Aragonese Jews, European astronomer stubs, Medieval Jewish astronomers, so understanding it makes those chapters shorter.
In everyday life
Look for Jacob ben Isaac Corsono 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.
