Mostafa Ahmadi Roshan is a physics 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 Mostafa Ahmadi Roshan rather than just read about it. In short: Mostafa Ahmadi Roshan (Persian: مصطفی احمدی روشن; 8 September 1979 in Hamadan – 11 January 2012 in Tehran) was an Iranian nuclear scientist who was assassinated in 2012. He was also deputy of commerce at the Natanz nuclear power plant.

Reference excerpt

Mostafa Ahmadi Roshan (Persian: مصطفی احمدی روشن; 8 September 1979 in Hamadan – 11 January 2012 in Tehran) was an Iranian nuclear scientist who was assassinated in 2012. He was also deputy of commerce at the Natanz nuclear power plant.

Life Ahmadi Roshan (also known as "Shahid Ahmadi-Roshan" after the assassination, denoting his status as a martyr) was born on 8 September 1979 in the village of Sangestan in Hamedan province, and grew up in a poor family. He was among the students of Aziz Khoshvaght (who was known as an Islamic moralist), studied polymer engineering at the Sharif University of Technology, and had published several Institute for Scientific Information (ISI) articles in English and Persian by the time he was 32 years old.

Family Ahmadi Roshan was married to Fatemeh Boluri-Kashani, who graduated with a master's degree in chemistry from Sharif University. His father was Rahim Ahmadi Roshan and his mother was Sedigheh Salari. His only child, Ali-Reza, was four years old when Ahmadi Roshan was killed.

Death Roshan was killed on 11 January 2012 by a motorbike bomb at 8:30am in the vicinity of Seyyed Khandan in Tehran. He was the last of four assassinated Iranian nuclear scientists (following Massoud Ali-Mohammadi, Majid Shahriari, and Darioush Rezaeinejad).

Natanz enrichment site In response to this and previous assassinations, a number of students from universities throughout the country sent letters to Iranian authorities, asking them to change the names of Iranian nuclear facilities and enrichment sites to those of the murdered scientists. Five of these requests were honored, and the Natanz enrichment site's name was changed to "The Site of Shahid Mostafa Ahmadi-Roshan".

Worked examples

Example 1 — a first encounter with Mostafa Ahmadi Roshan

Start with the simplest possible case. Write down what Mostafa Ahmadi Roshan claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Mostafa Ahmadi Roshan 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 Mostafa Ahmadi Roshan 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 Mostafa Ahmadi Roshan

In research: Mostafa Ahmadi Roshan appears in physics 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 Mostafa Ahmadi Roshan 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: Mostafa Ahmadi Roshan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1979 births, 2012 deaths, 21st-century Iranian engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Mostafa Ahmadi Roshan 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.
