Reference excerpt

Mohsen Fakhrizadeh Mahabadi (Persian: محسن فخری‌زاده مهابادی Fa-Kh-Ree-Zadeh; 21 March 1961 – 27 November 2020) was an Iranian nuclear physicist and scientist. He was regarded as the chief of Iran's nuclear program. Born in Qom in 21 March 1961, Fakhrizadeh joined the Islamic Revolutionary Guard Corps after the Iranian Revolution of 1979. He attended Shahid Beheshti University and later received a PhD from the University of Isfahan. Beginning in 1991, he was a physics professor at Imam Hossein University. Fakhrizadeh led the Organization of Defensive Innovation and Research and the Green Salt Project. Due to Fakhrizadeh's affiliation with the Iranian nuclear program, both the United Nations Security Council and the United States ordered his assets frozen in the mid-2000s. In the early 2010s, he established and led the Organization of Defensive Innovation and Research, which, according to the United States, conducted research potentially useful for nuclear weapons. Iran has denied that its nuclear programme has a military aspect. In 2018, Israeli prime minister Benjamin Netanyahu said that Fakhrizadeh was the head of the AMAD Project. Following his death, the Iranian government said that in 2020, he helped develop COVID-19 testing kits and a vaccine for use during the pandemic. On 27 November 2020, the Israeli government assassinated Fakhrizadeh in a road ambush in Absard using an autonomous satellite-operated gun. In a June 2021 television interview, former Mossad chief Yossi Cohen offered Israel's closest admission yet of its responsibility for the assassination. The Iranian government labelled the killing of the scientist an act of "state terror". The killing raised tensions in the region and the Iranian legislature passed a bill to block inspections of its nuclear program.

Early life Fakhrizadeh was born in a conservative family in Qom in 1961. He became a member of the Islamic Revolutionary Guard Corps (IRGC) after the Iranian revolution in 1979.

Career

Academic career (1991–2020)

Fakhrizadeh received his B.Sc in nuclear physics from Shahid Beheshti University in 1987. He continued his education at the Isfahan University of Technology and received a PhD in nuclear radiation and cosmic rays. According to Alireza Jafarzadeh, Fakhrizadeh was a member of the Imam Hossein University (IHU) faculty beginning in 1991. At IHU, located in Tehran, he taught physics. According to a 2007 CIA assessment conducted under President of the United States George W. Bush, Fakhrizadeh's academic position was a "cover story". In the early 2000s, Fakhrizadeh led an initiative called the Biological Study Centre, described as a successor to the Physics Research Centre (PHRC). The activities of this research group took place at Lavizan-Shian. In 2020, following his death, Fakhrizadeh was said (by the Iranian government) to have been a key figure in the fight against the COVID-19 pandemic, which hit Iran particularly hard (COVID-19 pandemic in Iran). According to Majid Takht-Ravanchi, Iran's ambassador to the United Nations, Fakhrizadeh led the team that developed the first Iranian COVID-19 tests. Iran's Defense Minister Amir Hatami reported that Fakhrizadeh had taken "great strides in the field of developing COVID-19 vaccine", later named FAKHRAVAC. He added that the center led by Fakhrizadeh went through the first phase of clinical human trials and "did great things for our dear people". On 29 November 2020, the head of the Coronavirus Battle Headquarters of Tehran paid tribute to Fakhrizadeh as a prominent scientist and distinguished scholar in research, technology and the health sector.

United Nations sanctions (2006–2007)

As of 2006–07, Fakhrizadeh was subject to a United Nations Security Council asset freeze and travel notification requirements because the Council said the International Atomic Energy Agency (IAEA) had asked to interview Fakhrizadeh and Iran refused to make him available. Iran has provided some information regarding Fakhrizadeh's work which the IAEA says is "not inconsistent with its findings", but the IAEA continues to seek corroboration of its findings. According to the UN designation, Fakhrizadeh was a senior Ministry of Defence and Armed Forces Logistics scientist and former head of the Physics Research Center (PHRC). The IAEA asked to interview him about the activities of the PHRC over the period he was head, but Iran denied the request. Fakhrizadeh was identified as a "key figure" in a 2007 report by the UN on Iran's nuclear programme. A 2007 UN Security Council resolution identified Fakhrizadeh as a senior scientist in the Ministry of Defence and Armed Forces Logistics and the former head of the Physics Research Center (PHRC) at Lavizan-Shian. In 2008, the United States ordered his assets frozen, along with those of other Iranian officials.

Organization of Defensive Innovation and Research (2011–2020) After the AMAD Project was discontinued, Fakhrizadeh established and led the Organization of Defensive Innovation and Research (SPND), a government-funded entity alleged by the US State department to be working on "dual-use research and development activities, of which aspects are potentially useful for nuclear weapons and nuclear weapons delivery systems." Transliterated Sazman-e Pazhohesh va Noavarihaye Defaee, SPND was founded in February 2011 and headquartered within Iran's Ministry of Defence and Armed Forces Logistics. Fakhrizadeh was SPND's director between 2008 and 2011. SPND was affiliated with Malek-Ashtar University of Technology. SPND is a subordinated organization of Ministry of Defence and Armed Forces Logistics.

Worked examples

Example 1 — a first encounter with Mohsen Fakhrizadeh

Start with the simplest possible case. Write down what Mohsen Fakhrizadeh 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 Mohsen Fakhrizadeh 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 Mohsen Fakhrizadeh 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 Mohsen Fakhrizadeh

In research: Mohsen Fakhrizadeh 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 Mohsen Fakhrizadeh 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: Mohsen Fakhrizadeh is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 births, 2020 deaths, 20th-century Iranian physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Mohsen Fakhrizadeh 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.
