Reference excerpt

Kitab al-Buldan (Arabic: كتاب البلدان, Book of the Countries) is a book written by the author, and geographer Abu Abbas Al-Yaqoubi (died 897) and it is one of the oldest Arab geographical sources dating back to the days of Abbasid Caliphate. The text describes many countries such as Iran, Turkestan, Afghanistan, Iraq, Egypt, Maghreb, and other countries in Asia and Africa. The first edition of the book was printed by the Dutch monarch, M. de Goeje, Leiden in 1850 and then in 1892. The book is a kind of "literary geography", because the book covers the history, ethnography, and myths related to the places.

Worked examples

Example 1 — a first encounter with Kitab al-Buldan (Ya'qubi book)

Start with the simplest possible case. Write down what Kitab al-Buldan (Ya'qubi book) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Kitab al-Buldan (Ya'qubi book) 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 Kitab al-Buldan (Ya'qubi book) 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 Kitab al-Buldan (Ya'qubi book)

In research: Kitab al-Buldan (Ya'qubi book) appears in science 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 Kitab al-Buldan (Ya'qubi book) 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: Kitab al-Buldan (Ya'qubi book) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 9th-century Arabic-language books, Abbasid literature, Geography books, so understanding it makes those chapters shorter.
