Song Yoo-geun

Song Yoo-geun (born November 27, 1997) is a South Korean person who gained recognition as a child prodigy in South Korea since 2004.

However, the paper was soon retracted due to concerns that it plagiarized a 2002 book chapter.

ApJ noticed that the paper plagiarized a 2002 book chapter, which had originally been a paper published by Song's advisor, Park Seok-jae.

Song Yoo-geun left a prodigy school he attended in 2003.

Six months of independent study enabled him to solve pre-calculus problems.

In August 2004, at age 6, he passed the "Craftsman Information Processing" (정보처리기능사) certification examination.

In November of the same year, his parents tried to enroll him at a local elementary school (Shim Seok Elementary School; 심석초등학교) as a sixth grader.

While Song did not perform well, obtaining a score of 12% on his math exam, his parents maintained that Song was neither used to, or interested in, calculating equations that lacked meaning.

Although the school allowed this at first, it later reversed its decision, citing administrative difficulties.

Song's parents took the elementary school to court, where the court ruled that the school's decision was unlawful in April 2005, allowing Song to study there as a sixth grader.

As Korean students must enroll in middle school within 30 days of the beginning of the school year, Song could not enroll in middle school even after winning the lawsuit.

Song's parents decided to opt for a Korean equivalent of the GED.

Song passed the test, which gave him the right to enroll in high school in May 2005.

He then went on to pass the test that certified him as a high school graduate in August 2005.

Thus, Song finished the twelve-year curriculum spanning elementary school – middle school – high school in nine months, setting a new record.

In October 2005, he applied and was accepted to Inha University through its early decision plans, which allow exceptional students to bypass the Korean equivalent of SATs, at age 7, making him the youngest university student ever.

During his interview with Inha University, Song demonstrated his understanding of the Schrödinger equation, a partial differential equation which is of central importance to quantum mechanics theory.

Considering his young age, Inha University formed a committee of seven, named "Song Yoo-Geun Committee," including professors and his mother, who gave him private lessons instead of the usual classroom style lectures.

Inha University also provided Song with his own lab, and a residence space, so that he can stay with his parents, at his parents' request.

His first semester GPA was 3.8/4.5, approximately equivalent to a B+.

During a press conference in 2005, after he was admitted to Inha University, he brought a machine that purifies air, and gave a demonstration of it.

The press and the Inha University officials reported that Song claimed it to be a machine that he invented himself, to thank the Korean citizens for their support.

It became known later that the machine was in fact designed by a small company.

According to the CEO of JC Technologies, Song's father told him that being able to show off the machine in front of the press would help with its sales, and he had borrowed the machine from the company.

Song's father quickly admitted this misunderstanding, saying that "Song has ambitions to study air purification methods using photosynthesis, so he just did a demonstration. There may have been parts where we were misunderstood, as this was our first large-scale press conference."

However, In December 2008, a mere two years after he had begun his studies, he decided to withdraw from Inha University, since he felt it was "difficult to study within the framework that the professors have arbitrarily decided for themselves."

He said, "I want to study string theory or big bang theory, but I cannot do that as an undergraduate student."

Of the 140 credits required for graduation, Song received 53 credits from Inha University, and 113 credits from an on-line degree institution.

On this, Inha University said, that it "respects Song's decisions. " To fulfill the total credit hours to apply to a graduate school, he achieved a Bachelor's degree using the Credit Bank System.

After graduating college in 2009, he was involved in a number of controversies during his ultimately unsuccessful doctorate program at Korean University of Science and Technology (UST), including one involving his paper in October 2015 written with his advisor, Park Seok-jae.

The paper, entitled "Axisymmetric, Nonstationary Black Hole Magnetospheres: Revisited" appeared in the Astrophysical Journal (ApJ).

He began at UST as a master's student in February 2009, with the intention of studying astronomy.

Like Inha University, UST formed a committee of professors, titled "Song Yoo-Geun Project," and Song was given private lessons in lieu of classroom lectures.

The topics of the lectures included quantum field theory, nuclear physics, astronomy, and topology.

The university set aside 100 million Korean won (approximately US$80,000) for Song's classes and research.

In February 2010, UST announced that Song had been accepted to its combined master's and Ph.D. program, with the goal of obtaining a Ph.D. in 2012.

He studied under the guidance of Park Seok-jae, whose specialized area is black hole modeling.

He passed his candidacy exam in November 2014, by a presentation entitled "Gromov-Witten Invariants on Real Hypersurfaces of Kähler Manifold, " and declared his intention to become a mathematician to the press.

However, he again changed his mind to study black holes.

In 2015, The Astrophysical Journal (ApJ) retracted Song's paper due to a plagiarism issue.
