Title: Lecture 12.3: The Amazing Alan Turing - Richard Buckland (extension lecture) UNSW 2008
Added: Apr 18, 2008
Author: UNSWelearning
Duration: 25:45
Description:
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.

Apr 22, 2011 - That's what i call a "Teacher". Respect to you sir!

Apr 22, 2011 - I do too like his enthusiasm, but why do a lecture on Alan Turing and talk about Enigma when you don't know things about them? There were quite a few errors in his historical knowledge.

May 16, 2011 - awesome lecture, the kind i might use to get friends who don't do math into stuff like this. BUT, i think you're wrong about the speed thing. the speed of a turing machine's computation can be multiplied by ANY constant factor, by appropriately increasing the number of symbols in the language, which must be finite, but therein can be arbitrarily large. so unless we have a computer that computes INSTANTANEOUSLY, we have a TM faster than all of them.

Turing's results were published in 1936 in his Entscheidungsproblem paper. Alonzo Church came up with an equivalent theory in the same year. So, no, Turing wasn't the first to answer No to Hilbert's challenge about decidability.

Dec 26, 2011 - This Lecturer does not seem to know the basic historical facts in Mathematics...It is depressing listening to this...."Alkjazori"? Oh dear! The correct name is Al-Khawarizmi (c. 780-850) , "Algorithm", who is known to every student of Maths. He is Persian and not Pakistani! Pakistan as a nation had not even been created yet (created recently in the 20th century)! Alan Turing who's known to every student of Computers and Maths was a scholar at University of Cambridge, UK!

Jan 4, 2012 - god damn shut up uthman. He knows everything about computer science and mathematics. God forbid he forget a few trivial facts about some fucking dudes exact name or his lineage. I bet this lecturer can own you in all things math and science.

Feb 18, 2012 - "Akazoweee, indian or Pakistani who envented algorithms....".....Ummm, is he talking about Mohammad ibn Musa al-Khawarizmi a scholar in the House of Wisdom in 9th Century Baghdad?

Mar 3, 2012 - Great stuff! Yay Turing! Simply fascinating!
dobraOsoba Says:
Mar 20, 2012 - what the hell are you talking about? America? They're like two different continents dude. Richard's students turn out great btw. I am only now starting to grasp the real importance of the concepts he teaches. I just wish that I have thought about this sooner and moved to AUSTRALIA<<--I consider his students the luckiest students in the world. Richard is a true revolutionary. Took me a while to realize that. Just watch his video about Gamification, and you'll see what i'm talkin 'bout

Mar 31, 2012 - i wish id had a professor like this when i was at uni. i can really see how this bloke can motivate his students. i think it would be amazing to sit through his lectures. if only there were more like him.

May 3, 2012 - can you please put the name of the subject this lecture is about? How are we supposed to know what subject is this lecture on? Algorithms, programming ?

May 12, 2012 - I want to have a lecture like this
jowens81 Says:
Apr 5, 2011 - @Blunic so strange to see this critique. I would have been enthused beyond belief to ever have a professor who was able to show half as much passion about a lecture topic.
