Turing Machine Primer - Computerphile

I like his voice, it's at that right soft, listenable sound

Thanks for this. Sometimes a step-by-step leading by the hand explanation is necessary for people like myself, and it is quite appreciated. I really love these nuts and bolts views under the hood of computing and I feel enriched watching the videos presented by an encouraging and wonderful instructor; it's absolutely fascinating that people have invented this stuff. People are awesome when they put their minds to things... I sure wish I'd been privileged enough to attend class taught by any of the instructors on these channels :0) Thanks Sean and all!

More videos Professor! It's really good to hear you explaining!

I almost didn't understand the Busy Beaver before this video was posted, now I don't understand why this video wasn't posted before Busy Beaver.

The professor is a legend

This was an excellent explanation, well done.  

THANK YOU!

Oh my God. The instruction card finally clicked for me. That took me FOREVER to understand!

I think it makes sense to have the head of the Turing machine move at every step.  If some Turing machine does not move on a given step, it can be combined with the next step because the next step will read the datum written on this step.

What if you have multiple heads reading and writing in that same (sending information or not between) time on multiple tapes.

Your video is wonderful! Thank you very much

My question is, what does it mean for a Turing Machine to have each register of the tape have an infinite amount of symbols instead of just a one and a zero? (To prevent the risk this thought experiment going into a higher computational complexity, I will say that the number of characters is a countable infinity.) Does this provide the ideal situation for a given program with the minimal number of registers as possible? (And I for one are for being self-destructive when it comes to Turing Machines, and allowing them to "rewrite" zeroes into zeroes or ones into ones. Because why not? It is so much better that way. And by better, I mean, makes things more complicated.)

You know, I would almost prefer a turing machine which doesn't follow Tibor Rado's method; one which instead keeps the program code on the tape like the Von Neumann architecture. This would allow the turing machine to be a universal turing machine and it just seems like a more pure model.

1:41 yes I'm completely masochistic xD

Why is this video unlisted?

Really great something that i inconsciously already know but without definiying all these therms.I was like wtf his just explain how cpu bit works then i realised aww that what we call a TM ^^

Binary Turing Machines just remind me of languages like Brainf*ck. Wonder if that's where they got inspiration.

This could be really simple to program myself, using arrays.

Interesting. Have watched all videos so far and yet little mention to how an upgraded version of a Turin machine makes a computer (because it is :) ).  The way this topic is put in this video series, makes obvious how fundamental this construction is. That's why, I like the video 'Turing & The Halting Problem' because it explores the limits of this type of machine, and any other type actually.
