Mahmoud Vahidnia

Mahmoud Vahidnia (Persian: محمود وحیدنیا‎‎) is an Iranian student. He is a second-year student in the Department of Mathematics at Sharif University of Technology.
Vahidnia got significant media attention for his face-to-face criticism of Iran's supreme leader on October 28, 2009, during a meeting between Ali Khamenei and students. During this meeting, Khamenei was challenged by Vahidnia in what was called "an unusual encounter". The event was being broadcast by Iranian state-run TV. That made the authorities stop airing the programme.

Vahidnia classified his criticism in four parts:

1. State-run TV: IRIB (Islamic Republic of Iran Broadcasting) for trying to show a reverse image of what is happening in Iran after June 12, 2009, election and destroying the figures that people trust. He brought up that since the head of IRIB is selected by the Supreme Leader, Ali Khamenei, Khamenei is either unaware of what is happening in an organization under his control or he has direct control and is responsible for their programs.
2. Freedom of speech: intelligence-based atmosphere ruling the media and press and brought up the issues that critical newspapers have been facing. He asked for an end to closure of press offices and demanded freedom of the press even when they criticize the supreme leader.
3. Supreme leader is criticize-able: Lack of openness in society so that people and intellectuals could freely criticize the supreme leader since the supreme leader, like anyone else, is prone to making mistakes. In his speech, Vahidnia mentioned that the ones around the supreme leader are making an idol.
4. Organization of power: Cycle of power in the Islamic Republic and the structure of Guardian Council and Assembly of Experts.

Vahidnia was ranked 37th on 2009 national math Olympiad in Iran and has received the gold medal for it. Although some media reported he was the "international mathematics Olympiad winner", he didn't compete at any international mathematics Olympiads.
