New design of British 50-pound banknote featuring 'father of computer science' Alan Turing announced

Bank of England Governor Andrew Bailey announced the design of a new £ 50 banknote on March 25, 2021.

The person depicted on the new plastic 50-pound bill is Alan Turing , a British mathematician known as the 'father of computer science' and 'father of artificial intelligence,' on June 23, 2021, the birthday of Turing. Will be issued.

It was announced in 2019 that Alan Turing will be featured in the portrait of the new £ 50 bill.

A portrait of Queen Elizabeth is depicted on the surface of the new £ 50 bill. In the UK, 10-pound and 20-pound banknotes have already been replaced with plastic polymer banknotes, and 50-pound will be issued as polymer banknotes. Holographic images, foils, and watermarks are used on 50-pound banknotes to prevent counterfeiting. In addition, it is said that the upper left corner has irregularities so that visually impaired people can be identified.

And the back of the new £ 50 looks like this. A portrait of Turing is drawn in the center, and the number table and formula in Turing's paper '(PDF file)

On Computable Numbers, with an application to the Entscheidungsproblem' published in 1936 are written in the background. I will. Also, what is written on the ribbon below the mathematical table and formula is Turing's birthday 19120623 converted to a binary number. In addition, technical drawings related to Turing's achievements are also included in the background. Next to the name, Turing said, 'This is only a foretaste of what is to come and only the shadow of what is going to be.' The passage that was told in the interview of the year is written.

Turing is known to have cracked the German cryptographic machine ' Enigma' during World War II. After that, he published the theory that is the basis of computer science and pioneered a research field on artificial intelligence.

However, Turing was unfairly arrested in 1952 for being homosexual and committed suicide in 1954 with potassium cyanide. In response, the government deliberated on the restoration of Turing's honor in 2012, more than 50 years after Turing's death, and was officially pardoned in 2013 in the name of Queen Elizabeth.

'Money depicts a national character. We have the right to bless the people with banknotes, so one of Britain's most important scientists, Alan Turing, is now £ 50. I'm glad to be drawn. Turing is best known for deciphering the enigma that helped end World War II, but he is a leading mathematician, developmental biologist, and He was also a pioneer in the field of computer science. He was also gay and was treated badly as a result. By designing him on a new 50-pound banknote made of polymer, we made his achievements and his Celebrate the value that symbolizes. '
