Film Alan Turing and his inventions

04 Feb

Mark1The film “The imitation game” especially expected by technologists and the digital world enthusiasts debut in Brazil from the day February 5, in many brazilian cinemas.
The author does your role Benedict “Sherlock” Cumberbatch is according to many critics, the perfect opportunity to let people know the person who contributes most to the computer, although the main mathematical model has been completed by the mathematician Alonso Church.
This is the point that separates art technology, as Turing managed to advance technology in a few decades more than many researchers all his life, and this because he lived only 42 years, having committed suicide by pressure suffered as a homosexual.
In 1936, with only 24 proposed a machine called “Turing machine” based on a tape that could be read in two directions (there were only cellulose tapes for film then), and the instructions would be of a character (letter, symbol or number), moving the machine forward or backward and could solve many problems.
During the war, the Allied submarines were being decimated at sea, and the communication was made in a code by a machine called Enigma, that Polish spies stole and made a replica, Turing studied and deciphered the code.
At the end of the war Turing worked in an English secret project that was operating an “electronic brain” called ACE (Automatic Computing System) that could calculate complex mathematical systems and not just equations, interrupted the project, but he worked in the Manchester Unviersidade a project that would be finalized, the Mark 1.
Later ACE 15 computers were sold and the first personal computer, called Bless G-15 was totally based on this model.
One of the first devices that made the voice encryption was done by Turing, called Deliah, and later developed the SIGSALY at Bell Laboratories, USA.
Turing always had a correct concept of intelligence, for it was not a question whether machines think but could imitate humans, worked in 1941 in “machine intelligence” because in 1947 used the term “artificial intelligence” and in 1950 published a study “artificial intelligence“, one of the first mentions of the term.
The “Imitation game” is his most famous contribution, put hidden people and computers and suggest things to know where it was either.
