- From cryptanalysis and the cracking of the German Enigma Code during the Second World War to his work on artificial intelligence, Alan Turing was without doubt one of the greatest minds of the 20th century. An extraordinarily gifted mathematician, he is rightly regarded as the father of computer science having set in place the formal rules that govern the way every computer code ever written actually work. This lecture will be a celebration of one man's enigmatic yet ultimately tragic life - a whirlwind tour of his genius, from whether computers can have consciousness to how a leopard gets its spots.
Presented by Professor Jim Al-Khalili, Professor of Physics and Professor of Public Engagement in Science from the University of Surrey.
Jim Al-Khalili OBE is an Iraqi-born British theoretical physicist, author and science communicator. He is Professor of Theoretical Physics and Chair in the Public Engagement in Science at the University of Surrey. He has become a familiar science personality in the British media. He has hosted several BBC productions about science and is a frequent commentator about science in other British media venues.
This was a joint lecture between the Royal Society of Edinburgh and the University of Edinburgh School of Informatics.
Recorded on Thursday 10 May 2012 at the George Square Lecture Theatre, The University of Edinburgh.

How terrible and unfortunately ironic that Turing would be subjected to a discrimination and oppression so similar to that which he had previously worked so hard to fight. I feel honoured to be able to write my appreciation towards him using a machine that is derived from his work.
Hats off to Turing.
Thank you so much Jim, and CZcams. Another piece of the puzzle thrown to us wanting to learn. Cheers SBM.
Jim is a remarkable physicist and lecturer. He really was uncharacteristically nervous in the beginning lol. Its always a treat to hear about Alan Turing. I have a very special place in my heart for Turing, whom i believe is the greatest mind humanity has ever seen. The true father of computers, and largely unknown to the common public. For 50 years, he was all but stricken from history due to his sexuality. Thankfully, that is changing. Benedict Cumberbatch plays Turing in the 2014 film 'The Imitation Game'. His performance is riveting. I highly recommend it.
This was truly amazing, thanks for sharing.
thanks for uploading
you're welcome :)
nice post thanks for sharing EdinburghUniversity
The story of civilisation, the question is : would it be the same as it is in this day and age without Alan Turing ? was it meat to be like this ?
Turing was a genius Tommy Flowers was an exceptional electrical and electronics talent.Both were heros !
I think its spelt .... Heroes 🤭🤭🤭🤭
Tommy Flowers designed the Colossus which helped to break the Lorenz (not Enigma) cipher.

The enigma was and still is, a "code machine" NOT a "code". It was capable of sending coded messages, by scrambling them into indecipherable texts.....and when receiving scrambled coded messages, by unscrambling them into clear text....the Germans used 4 (four) different code machines during WWII, the one in most common use at the tactical level by the German military and German government agencies/departments was the enigma code machine......the one in less common use at the strategic level by Hitler and the High Command levels was the Lorenz code machine, a much more highly technically complex than the enigma.....for example the Lorenz used 12 rotors in an automated teletypewriter format, those rotors and the Lorenz more complex wiring and setting systems scrambled the codes it sent by several hundred million, million, million etc times. The emphasis placed by the public on the enigma code machine is very interesting, however, the development of the high speed analysis system by Alan Turing was greatly superceded by another higher speed analysis system by others at Bletchley Park than Alan Turing. His work however in designing and making his "code-breaking" system did highly contribute to the one then designed to "crack" into the codes sent and received by the Lorenz system. In addition to that fact, there were literally hundreds of others employed at Bletchley Park who did the footwork to "get into" German codes, their identities and extremely important contribution to breaking codes are just now being revealed and recognized....!
1968 in Skopje jugoslava,macedonia start APSTRCT MATEM MACHINES ON UNIV OF SKOPJE. WE MADE MATH-KIBERN SKOOL. WE LEARN TURING LOGIC TABLES. I HAVE ONLY 18 Y.OLD. AND START STADY MEDICINE. DADY WANT DOCTOR IN FAMILY. WAT APITY. RUSSIAN SCOOL IS GOOD.
For me, computers will never become conscious. To think that it is only a matter of waiting long enough for evolution to do it is nonsense. That would be like playing around inside a closed building and believing that with enough time, and enough favourable accidents, you will somehow find yourself inside another building.
To see how ridiculous it is, it is like Nicola Sturgeon pontificating inside the Scottish Parliament, and thinking there is something she can say that will magically get her into the Berlaymont Building, in the EU.
