The Turing Test
A man before his time, Alan Mathison Turing is arguably one of the most recognized mathematicians of the 20th century. In 1950, he published a paper that, to this day, sets the standard for artificial intelligence. He proposed a way to determine if a machine has intelligence, and this is now called the Turing Test.In his 41-year life, Turing accomplished a great deal as a mathematician. Bordering on many philosophical issues, his work is recounted in this online biography (1). A very good introd
