Looking At Turing

Jim Jones has written in with the first of a series that explores the history of Mr. Alan Turing, and his connection with digital computing.

Not very detailed

It would be useful if they went into more details, eg what a turning machine is.

Alan Turing

[serpent0r]

I must say, Alan Turing is my favorite computer scientist, however I don't believe he get's the recommendation that he deserves. They just created a memorial for him, and the site states that they could not find funding from not even one major corporation. They had to rely on donations from the public. Here is the site.

Re:Alan Turing

[ChazeFroy]

I think just about every school with a Computer Science program has a machine named "turing". It's kind of like naming schools after famous people, but in a geeky way :-)

You don't mean this book, do you? It doesn't appear to be out of print...

The classic five-star book on Turing

[SimHacker]

Alan Turing: The Enigma is the classic and most excellent biography of Alan Turing, that was recently re-issued.

Check out the great review on Amazon by Fidonet founder and homo-anarchist Tom Jennings!

Here is the Amazon review by Tom Jennings of the classic book Alan Turing: The Enigma.

Much more information about Alan Turing and the book is on the web page created by Turing's biographer, Andrew Hodges: The Alan Turing Home Page.

One of the most important books I've ever read. Without this book, the real Alan Turing might fade into obscurity or at least the easy caricature of an eccentric British mathematician. And to the relief of many, because Turing was a difficult person: an unapologetic homosexual in post-victorian england; ground-breaking mathematician; utterly indifferent to social conventions; arrogantly original (working from first principles, ignoring precedents); with no respect for professional boundaries (a 'pure' mathematician who taught himself engineering and electronics).

His best-known work is his 1936 'Computable Numbers' paper, defining a self-modifying, stored-program machine. He used these ideas to help build code-breaking methods and machinery at Bletchley Park, England's WWII electronic intelligence center. This work, much still classified today, led directly to the construction of the world's first stored-program, self-modifying computer, in 1948.

Computers were always symbol-manipulators, to Alan, not 'number crunchers', the predominant view even to von Neumann, and into the 60's and 70's. He designed many basic software concepts (interpreter, floating point), most of which were ignored (he wasn't exactly good at promoting his ideas). By 1948 Alan had moved on to studying human and machine intelligence, as a user of computers, again with his lack of social niceties and radical thinking, some of his ideas were baffling or embarrassing until 'rediscovered' decades later as brilliant insights into intelligence. His 'Turing test' of intelligence dates from this period, and is still widely misunderstood.

Poor Alan; his refusal to deceive himself or others and "go along" with the conventions of the time regarding sexuality caused him (and other homosexuals then) great problems; early Cold War England was not a good time to be gay, or a misfit, especially one with deep knowledge of war-time secrecy (he was technical crypto liason to the U.S., and one of the few with broad knowledge of operations at Bletchley, since he defined so much of it, in a time of extreme compartmentalization). His sexual escapades eventually got him in trouble, and his increasing isolation and the fact that he simply couldn't acknowledge some of his life's work due to secrecy, probably influenced his suicide at the age of 42.

I first discovered Turing-the-person in A HISTORY OF COMPUTING IN THE 20TH CENTURY (Metropolis, Howlett, Gian-Carlo Rota; Acedemic Press, 1980), where I.J. Good wrote, "we didn't know he was a homosexual until after the war... if the security people had found out [and removed him]... we might have lost the war". This led me to look for books on Turing, and then the Hodges book magically appeared on the shelf.

I am grateful that Hodges researched his life as well as his work, as far as the data allows. Knowing the whole is always important, but I think critical in Alan Turing's life. Clearly, I rate this one of the most important books I've ever read.

Re:Cryptonomicon.....

[4n0nym0u53 C0w4rd]

Although Turing was in Cryptonomicon, you have to remember that it is fiction. The fact is, it does take liberties with the truth in the name of dramatic license.

For a good biography of Turing, you should check out Hodges' Alan Turing: The Enigma. A bit of a dense read, but informative and comprehensive.

Re:can we please evolve

[The Ape With No Name]

If I remember correctly, in Leviticus, it also says that anyone who touches the skin of pig shall be cast out the village. I guess that means anyone who plays American Football is a filthy, remorseless heathen. At least, when the ball was made of pigskin...

The Enigma -- actual best book about Turing

[Anonymous Coward]

If you want a really in-depth book about the actual Turing, read this excellent biography (don't me wrong, Cryptonomicon is an excellent work of fiction, and seems to grab his personality well, but this is the official biography).

here's a link:

Another recommended book

[Anonymous Coward]

"Engines of Logic" by Martin Davis. Covers Turing and a host of others who contributed to the digital computer. Strong mathematical bent.

Turing Unfortunate End

[Anonymous Coward]

Unfortunately Alan Turing suffered at the hands of the US government. His house was ransacked by a theif, he was also living with a man at the time. Police questioned Turing and Turing admitted to his homosexuality. At the time being a homosexual was illegal and Turing was forced into chemical treatments for his homosexuality (hormone treatment). After the humilation he recieved from the US government, whom he helped during WWII w/ his cipher "bombs" (mathematical devices that ticked) Alan Turing took his own life by eating a cynanide ladden apple.
