Lecture 12.3: The Amazing Alan Turing - Richard Buckland (extension lecture) UNSW 2008

We had a gap at the end of Lecture 12 so Richard gives an unplanned and impromptu talk about some of the contributions of the amazing thinker Alan Turing. So much to say, so little time, such fast talking.

We chat about 3 different major contributions he made to the world - his decryption work during WWII and the Engima Machine; his abstract model of a computer (the Turing Machine) and what things can be effectively "computed"; and finally, briefly only, his thoughts about what it is to be human and the difference between humans and computers - the Turing Test.

Alan Turing is a key figure in the development of computing, indeed if I had to pick just one thinker who was the most amazing he'd get my vote.

Richard promises to talk about the Turing Test in more depth in the next extension lecture.

Also comes up:
Epimenides paradox, non computable functions, the halting problem,
U-559, Colin Grazier G.C., Anthony Fasson, G.C.,Tommy Brown, Blade Runner,
CAPTCHAs.

Errata:
My memory was about as reliable as usual - I said Tommy stayed outside in a boat but i've since read that all three swam across and went into the U-559. Humbling bravery. I've also since realised that Colin Grazier was from Tamworth in the UK, not the Tamworth in Australia as I had always thought (why are so many English places named after Australian towns?) Finally, something which actually I did know but still managed to get wrong - the important material salvaged was not a cypher machine but quantities of data (ciphertext and the corresponding plaintext I think) which the codebreakers at Bletchley Park were able to use as "cribs" and were of vast help in cracking the submarine code used at that time.

Engrossed in the lecture but I'd like to point out that Colin Grazier (who got the enigma machine out of the German U Boat) was from Tamworth, Staffordshire ENGLAND! Not Tamworth Australia!

yes absolutely, you are quite right - the new youtube layout makes it harder to see the description attached to the video but we did print a correction there saying exactly that when we uploaded the vid back in 2008. The actions of those three men were truly humbling.

That's what i call a "Teacher". Respect to you sir!

Awesome

He was repeating the question out loud that one of the students in front asked him..

[maluk2211]

Was Turing a paedophile?? Is this the standard of Australian education. This is not learning this is Chinese whispers. You expect a university lecturer to be a bit more knowledgeable than his students.

oh...kay...you alright buddy?

[IronAnimation]

Probably. I make no pretense of worth or value, I'm happy with being excited over a story.

[Paul Collins]

There is a very good British movie available on DVD about the "Enigma" machine. It is called "Enigma" starring Kate Winslet.

great teacher, great teaching style ... :D ...absolutely <3 it

[IronAnimation]

Oh my god, this man is amazing. I'm a stupid kid and I hung onto every word. This is so cool.

looks like John Green!
