The Persian Encyclopedia

The Persian Encyclopedia is a science 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 The Persian Encyclopedia rather than just read about it. In short: The Persian Encyclopedia (Persian: دایرةالمعارف فارسی; Romanized as Dāyerat-ol-ma'āref-e Fārsi) is one of the most comprehensive and authoritative Encyclopedias written in Persian. It is a two-volume encyclopedia published as three physical volumes.

Key takeaways

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

Reference excerpt

The Persian Encyclopedia (Persian: دایرةالمعارف فارسی; Romanized as Dāyerat-ol-ma'āref-e Fārsi) is one of the most comprehensive and authoritative Encyclopedias written in Persian. It is a two-volume encyclopedia published as three physical volumes. The encyclopedia was based, in part, on the 1953, 1960, and 1968 editions of The Columbia Viking Desk Encyclopedia. It was initially published under the supervision of Gholamhossein Mosahab. He started the project in 1955 in the Franklin Book Programs office in Tehran. Mosahab left the project after the first volume (words starting with Alef to Seen) was published in 1966. The second volume was actually published in two "parts", making the encyclopedia three physical volumes. The first part (Sheen to Lām) was published in 1978, ten years after the first volume. It was supervised by Reza Aghsa. The Iranian revolution in 1979, the death of Mosahab in the same year, and the takeover of the assets of the Franklin office in Tehran by the government delayed further publication. The second part (Meem to Yeh) was published by Amir Kabir Publishers in 1996, eighteen years after the first part of the volume, but not mentioning a new supervisor's name. The encyclopedia total is 3385 three-column pages. The encyclopedia contains an introduction that explains in detail the principles and methods of work and how to use the encyclopedia. This encyclopedia has 43,000 entries, of which 23,000 are foreign entries, 11,000 are related to Iran and Islam, and the rest are reference entries. Foreign entries are generally translations and adaptations, but entries related to Iran are entirely authored. The three volumes were republished with minor changes by Amir Kabir Publishers in 2002 (ISBN 964-303-044-X).

Worked examples

Example 1 — a first encounter with The Persian Encyclopedia

Start with the simplest possible case. Write down what The Persian Encyclopedia 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 The Persian Encyclopedia 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 The Persian Encyclopedia 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 The Persian Encyclopedia

In research: The Persian Encyclopedia 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 The Persian Encyclopedia 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: The Persian Encyclopedia is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century encyclopedias, Culture of Iran, Encyclopedia stubs, so understanding it makes those chapters shorter.
In everyday life: Look for The Persian Encyclopedia 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.
