Alan Turing
Alan Mathison Turing , OBE , FRS ( pron.: / ˈ tj ʊər ɪ ŋ / TEWR -ing ; 23 June 1912 – 7 June 1954), was a British mathematician , logician , cryptanalyst , and computer scientist . He was highly influential in the development of computer science , giving a formalisation of the concepts of " algorithm " and " computation " with the Turing machine , which can be considered a model of a general purpose computer. [ 2 ] [ 3 ] [ 4 ] Turing is widely considered to be the father of computer science and artificial intelligence . [ 5 ] During World War II , Turing worked for the Government Code and Cypher School (GC&CS) at Bletchley Park , Britain's codebreaking centre. For a time he was head of Hut 8 , the section responsible for German naval cryptanalysis. He devised a number of techniques for breaking German ciphers , including the method of the bombe , an electromechanical machine that could find settings for the Enigma machine .

Hadrian
Hadrian ( Latin : Publius Aelius Traianus Hadrianus Augustus [ 1 ] [ 2 ] [ 3 ] 24 January, 76 AD – 10 July, 138 AD), was Roman Emperor from 117 to 138. He is best known for building Hadrian's Wall , which marked the northern limit of Roman Britain . In Rome, he re-built the Pantheon and constructed the Temple of Venus and Roma . In addition to being emperor, Hadrian was a humanist and was philhellene in most of his tastes. He was the third of the Five Good Emperors . Hadrian was born Publius Aelius Hadrianus to an ethnically Italian family, either in Italica near Seville (in modern-day Spain ) or in Rome.
Artificial Intelligence ( AI ), a branch of computer science , is the study of intelligent systems (i.e. software, computers, robots, etc.). Alternatively, it may be defined as "the study and design of intelligent agents", [ 1 ] where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success. [ 2 ] John McCarthy , who coined the term in 1955, [ 3 ] defines it as "the science and engineering of making intelligent machines". [ 4 ] AI research is highly technical and specialised, deeply divided into subfields that often fail to communicate with each other. [ 5 ] Some of the division is due to social and cultural factors: subfields have grown up around particular institutions and the work of individual researchers. AI research is also divided by several technical issues.
