THIS 1936 Paper Theorized the FIRST Computer EVER, by Alan Turing

In 1936, Alan Turing wrote a paper that changed the course of history, titled "On Computable Numbers, with an Application to the Entscheidungsproblem", first introducing the Universal Turing Machine and laying the theoretical foundation of modern computing . It revolutionized the field of computer science and ultimately led to the development of technologies that have changed the world as we know it.

This new style is really dope. I've been watching you for years and this is a really nice progression. Please keep doing more of these

[@lawrencedoliveiro9104]

Turing also published a groundbreaking paper in an entirely different field, namely biology. He was considering the issue of how the amorphous mass of cells making up a fertilized embryo can suddenly decide that this is its “front” and this is its “back” and that is “the left side” and that is “the right side”.

Wow😍 I would love to see more videos about the history of CS and the brilliant ideas those early scientists!

7:51 Church and his student Kleene did some interesting work with the λ-calculus. For example, they showed how mathematical paradoxes (like Russell’s paradox) could be represented by expressions that could be manipulated logically without the whole world collapsing about your ears. Mathematicians go to great lengths to try to ensure that their theories are free of paradoxes. But I think λ-calculus shows how you can tame the paradox and not be afraid of it.

[@rumplstiltztinkerstein]

Never forget the reason why Alan Turing passed away. He could have kept making breakthroughs in computer science. But he was prosecuted for "homosexual acts". He accepted "hormone treatment" to avoid going to prison, and eventually took his own life with Cyanide. Every time someone praises Alan Turing for his achievements, don't forget what was done to him. Thank you for shining a light on his achievements Forrest.

So fucked up they did him like that. He should have been celebrated as a modern hero. Not persecuted for liking men.

[@reginaldcobb4356]

I love these documentaries. I think a journey down the mini- and super mini-computer history would be interesting. I cut my teeth on those in the late 80's. Also, programming languages.

[@arsnakehert]

The core of this particular one of Turing's achievements that became a legacy for computer science was formalizing the notion of an algorithm; Turing machines _are_ algorithms, and the notion of a _computer_ is the _universal_ Turing machine, these are also _algorithms_ that can basically run any other algorithm given its description and input In a sense, computers such as we know them are hardware implementations of something like UTMs, just like chips that encode and decode video are hardware implementations of the particular algorithms they implement UTMs can also simulate the operation of other UTMs given their description (and input), which is what makes the notion of emulators start to feel natural and not like black magic; this is something that blew my mind to squishy bits onto the walls and ceiling when I learned it

[@arsnakehert]

The other part of this which blew my mind was the notion that the physical existence of a computer is, at least from the point of view of theoretical computer science, a mere implementation detail; a CPU and memory and the circuits that put them together are, in a sense, just the physical implementation of a particular "assembly interpreter". A programming language with its computing model is just a legitimate a "computer", again, from this theoretical point of view.

[@arsnakehert]

Even the way we think about C is fairly abstract. The C computing model we usually imagine is something like a physical PDP-11, but we don't get to touch on the complexities that modern CPUs (or even your OS) do behind the scenes. We can at best sometimes nudge at some CPU details to indirectly cause the computer to act the way we want. I mean stuff like memory alignment, and optimizing for cache locality, for instance, but even branch prediction and whatnot. We don't really get to touch that directly, I think. So even C has an abstract computing model between itself and the lower implementation details that we're not even aware of. Yet we still see it as a fairly reasonable approximation of dealing directly with the machine.

[@TheFuture36520]

Alan Turing, Nikola Tesla, Ada lovelace, Thomas Edison, Charles Babbage, Issac Newton, Einstein and Michael Faraday. My hero's 🥰😍

[@Fuji_9.63]

Issac Newton yes, einstein, not so much.

[@lawrencedoliveiro9104]

6:18 Worth making something very clear here: the program (call it D, the “deciding program”) that decides whether a given program (call it P, the “problem program”) will terminate for input data I is taking both P and I as input data. In other words, a program is input data to another program! This is a key point about the nature of the Turing machine, and also of all our electronic digital computers: programs and data are both represented using the same set of symbols that can be stored in the memory of the machine. The only difference between the two is, a stream of symbols becomes a “program” only because you point the CPU at the start of that stream and say “run this as a program”.

[@lawrencedoliveiro9104]

5:20 That “which implies” part has not actually been proven. It’s called the “Church-Turing thesis”, and the mathematical term for it is a “conjecture”. It seems to be true, as far as we can tell, in all the examples so far, but, as for the general case, we can’t be sure either way.

I see Walter Isaacson's innovators there, is there where you get the idea to make a video about alan turing and can we expect more videos like these on computer science pioneers?

Did you mean to say "THIS 1936 Paper by Alan Turing Theorised the FIRST Computer EVER". Turing did not build a computer, ever.

[@Barxxo]

"Theorized the FIRST Computer EVER" From the american point of view. In Germany Konrad Zuse presented his first working computer, the Z3, in 1941. I am therefore sure Mr. Zuses ideas predate Mr. Turings paper. Since this happened during the war and the Nazis were not especially smart, they didn't understand the potential of Zuses machine.

[@jamesc3505]

My understanding is that, while the Z3 was in theory Turing complete (i.e. given infinite memory and infinite time, it could be used as a general-purpose machine), it was in practice unworkable as a general-purpose machine. I don't think there's any reason to believe that Zuse had intended to build a general-purpose machine. If he had, surely he would have designed it to be a workable one. However, I don't think I'd say Turing theorised the first computer either. I think Charles Babbage's analytical engine was a design for a computer (although never built) from around 100 years earlier.

[@gSys1337]

Fun fact: Turing did mayor work to beat the Germans in the second world war.
