Who is the mathematician that memorized a lot of numbers of pi?

Answer 1

Daniel Tammet. A twenty-something with extraordinary mental abilities, Daniel is one of the world's few savants. He can do calculations to 100 decimal places in his head, and learn a language in a week.

He also meets the world's most famous savant, the man who inspired Dustin Hoffman's character in the Oscar winning film 'Rain Man'

This documentary follows Daniel as he travels to America to meet the scientists who are convinced he may hold the key to unlocking similar abilities in everyone.

Andriy Slyusarchuk claims to have set a number of records in memorizing large volumes of digital data, sequences of geometrical figures, as well as words and other information. In particular, he claims to have memorized 1 million digits of pi figure.

By 2008 he claimed to remember 2,000,000 decimal places of pi, as well as around 7,000 volumes of text. By 2009 the number of volumes remembered increased to 15.000.

By June 2009 he claimed to have set a new record by memorizing the first 30 million places of pi, which were printed in 20 volumes of text. Although he did not recite all 30 million digits that he claimed to have memorized, he was able to recite randomly selected sequences from within the first 30 million places of pi.

Since reciting 30 million digits of π at one digit a second would take almost a year (347 days) if you did it non-stop 24 hours a day, seven days a week, a following approach had been applied to verify the record: during demonstrations Mr. Slyusarchuk is being randomly asked to tell the digits of pi printed on certain pages and locations of the 20 volume printout, which is grouped into orderly arranged tables. He successfully went through this kind of test multiple times. Demonstrations had been witnessed by respectable scientists and heads of sub-departments in Universities. Book of Records of Ukraine (Книга рекордів України) lists the members of commission witnessing his demonstration.[38] They are country-wide recognized scientists on the top positions in National Universities and Institutes.

By October 2010 Mr. Slyusarchuk claimed to remember 200 million decimal places of pi.

None of his claimed Pi records is accepted by the official Pi World Ranking List [40] or the Guinness Book of Records since no real independent test of his pi knowledge was possible ever.

Mr. Slyusarchuk is known for his hypnotic skills as well. In particular, he claims to be able to hypnotize people so as to not feel pain, e.g. when exposed to burns.

Another TV show presented him hypnotizing students of L'viv University of Modern Technologies (Львівський державний інститут новітніх технологій та управління ім. В. Чорновола). Those under hypnotic influence could eat onions believing those were apples.

He also demonstrated hypnotizing a salesman in a shop to take a 1 hryvna bill from him, believing this to be 500 Hryvna.

Novyi Kanal has hosted a few TV events in which Andriy Slyusarchuk demonstrated many of his extraordinary abilities. The Video recording of the events is available at http://video.novy.tv/video/3/24/9842.html .

When trying to show exceptional Chess position memory on TV (memorizing all pieces on 80 boards), he was criticized by a chess master invited to the event (Grigoriy Timoshenko). An article in The New York Times called Slysarchuk "an Illusionist".

He was also officially invited to participate in the World Memory Championships, where his feats would have been tested by independent international arbiters. He was promised 40,000 US$ if he broke the accepted memory records, but he refused to go there
