Alan Turing and the Machine of ThinkingS0:

"The fact remains that everyone who taps at a keyboard, opening a spreadsheet or a word-

processing program, is working on an incarnation of a Turing machine."

Alan Turing and the Machine of ThinkingS0:

Turning Machine

He proved that some such machine would be capable of

performing any conceivable mathematical computation if

it were representable as an algorithm.

Alan Turing and the Machine of ThinkingS0:

Turning Machine

Every algorithm can be expressed in a language for a computer consisting of only five basic instructions:

• move left one location• move right one location• read symbol at current location• print 0 at current location• print 1 at current location

"von Neumann ... firmly emphasised to me, and to others I am sure, that the fundamental conception is

owing to Turing—insofar as not anticipated by Babbage, Lovelace and others."

September 1939

joined by other mathematicians at Bletchley Park, Turing rapidly developed a new machine (the ‘Bombe’) capable of breaking Enigma messages on an industrial scale.

Alan Turing and the Machine of ThinkingS0:

Artificial Intelligence

In 1950, he published a paper entitled Computing Machinery and Intelligence, in which he explored the notion.

In the paper, Turing suggested that rather than building a program to

simulate the adult mind, it would be better rather to produce a simpler one to simulate a child's mind and

then to subject it to a course of education.

Hacking for Designers

Alan Turing and the Machine of ThinkingS0:

The idea was that a computer could be said to "think" if a human interrogator could not tell it apart, through conversation, from a human

being.

His Turing test was a significant, characteristically provocative and lasting

contribution to the debate regarding artificial intelligence, which continues after more than

half a century.

Since 1966, the Turing Award has been given annually by the Association for Computing

Machinery for technical or theoretical contributions to the computing community.

It is widely considered to be the computing world's highest honor, equivalent to the Nobel

Prize.

Alan Turing and the Machine of ThinkingS0:

Charles Babbage(December 1791 – October 1871)

Considered by some to be a "father of the computer”, Babbage is credited with inventing the first mechanical computer that eventually led to more complex designs. His varied work in other fields has led him to be described as "pre-eminent" among the many polymaths of his century.

Alan Turing and the Machine of ThinkingS0:

Ada Lovelace(December 1815 – November 1852)

Chiefly known for her work on Charles Babbage's early mechanical general-purpose computer, the Analytical Engine. Her notes on the engine include what is recognized as the first algorithm intended to be carried out by a machine. As a result, she is often regarded as the first computer programmer.
