Alan Turing

Computing is normally done by writing certain symbols on paper.

I am to be remembered as the man who broke the Enigma code.

Logic can become enormously intricate, and as you try to grapple with it you sometimes find your mind whirling around and around.

The successful use of new methods requires a new type of worker.

I propose to investigate the question as to whether such a machine can be made to think.

Anyone who feels at ease with decimal notation is clearly not thinking hard enough.

The real question is, 'What are we going to do?'

It was a very difficult problem, but we solved it.

I don't see why I shouldn't enjoy life.

The number of states must be finite.

We do not need to know much about the workings of the brain to understand the nature of intelligence.

Programming is a four-letter word.

The original question, 'Can machines think?' I think is too meaningless to deserve discussion.

I am always ready to learn, although I do not always like being taught.

What we want is a machine that can learn from experience.

The brain is only a computer made of meat.

In practical terms, my computing machine would have to have a million times as much power as the machine I used for my first calculations.

I have had a very interesting life.

The Imitation Game... the only way by which one could be sure that a machine thinks.

Mathematics is the part of physics where experiments are cheap.
