Alan Turing's 100th birthday marked by Google doodle

Google on Saturday marked the celebrations of the 100th birth anniversary of computer scientist Alan Mathison Turing with an attractive doodle. Turing, who is also known as the founder of computer science, played a significant role in breaking the wartime Enigma- enciphered messages.

Search giant has put up a very interesting doodle, which is actually a mock-up of Turing machine and users have to spell the word 'Google' in the binary code to solve it.

Turing was an English mathematician, logician, cryptanalyst and computer scientist. He was known for his contribution to the development of computer science and providing a formalisation of the concepts of "algorithm" and "computation" with the Turing machine. He is also widely considered to be the father of computer science and artificial intelligence.
