Doc of the Day: Tracing the Path of Computer Science

[@DJ-KAOS]

Jim's a great guy and his science videos are some of my favourite. The content is utterly fascinating and it's presented in a way that allows ordinary people like myself to understand it. It's just such a MASSIVE SHAME that some sections of his videos are often spoiled by the noisy backing tracks that completely drown out the narrating 😕 If you enjoy his videos as much as I do, I recommend you watch the one about the history of electricity. I promise you will not be disappointed 😉

Thank you for the recommendation. These are just top tier productions. And I completely agree about the sound. I must be getting older because I often feel this way.

[@TerrydanielDavidson]

I feel privileged to have met Jim A-K several times as my father worked at Surrey University as a project manager with their data systems. And I can say with confidence that he's as engaging in person as he is in his videos. He really is a national treasure.

[@richardhedd3080]

I wish I had a teacher like Professor Jim Al-Khalili when I was younger. I might have learned something.

[@PaulThatcher-iu5in]

Not to diminish Jim's achievements, but he and I had the same Physics teacher at Priory School, Portsmouth, then a Comprehensive, 40-odd years ago - and to its credit, that school and its teachers fostered that spark of curiosity about science in many of us. Me, I'm a linguist and language teacher, but never lost that love of Physics, so that now, all these years later, I'm still on the road of discovery...

[@andersonfernandes7753]

When I was a child we used to write letters and sent telegrams. I loved the etiquette for personal, business, and legal correspondence. Then telephones became affordable and very popular. People forgot how to write a simple memo. A few decades later we were using cell phones and laptops. We went back to writing.....no etiquette or grammar rules. All these changes in a very short period of time if I consider I'm in my 50s'.... 😮mind blowing.

[@higgsboson2280]

[@zeitfieldunite4488]

Jim does a great job explaining with clarity at a certain speed for all to understand. Overall a great documentary, obviously from a British perspective gives Alan Turing praise although there are many poineers who contributed to computer science, a bit of diplomacy. Like Michio Kaku the japanese lecturer from New York who glorifies Albert Einstein, a patriotic path

[@rstidman]

it was great, but I could have done without the masturbating demon. just kidding, the masturbating demon was cool too.

[@rudihoffman2817]

My goodness, this is amazing education. Having read many books on human progress and science, I thought this would be redundant. But the way Jim K related this info is just delightful!

[@exe.m1dn1ght]

21:57 this clicked for me ! superb documentary !

[@kevg3563]

Interesting video. However, a small mention about teleportation of actual physical objects would have been good. For example.... You scan a drinking cup using a modern 3D scanner, then send the data over the internet to someone the other side of the world. The receiver then uses the data to recreate an exact physical copy of the cup using a 3D printer. When you think about it, it is a form of teleportation.

[@julianjames1971]

Not really its just making a copy. The original hasn't moved.

[@PaulThatcher-iu5in]

NOT teleportation: instead of Capt Kirk and Lt Uhura zipping about the galaxy, there would be hundreds of copies of them all over the place - a solution I would be in favour of, as multiple William Shatners would have crashed Bezos' 'Blue Origin', while multiple Nichelle Nichols would have meant I might have actually met my crush from when I was 12 years old...

[@FARDEEN.MUSTAFA]

It was a great documentary about Classical information of Classical Algorithms in Classical World. Professor Jim Al Khalili is a great Physicist. It's great to learn Quantum Physics from Great Minds. My favorite Quantum Information are Dark Energy's 120 0s and one 1s, Voyager 1's 32 0s and 1s which didn't make sense for data scientists and engineers. I love tricky information. I like 0s and 1s. How beautifully these 0s and 1s indicate black and white era of modern science and technology. If computer scientists follow James Clerk Maxwell method of devil, definitely the most beautiful and Quantum Particles of Cosmos become Dark Matter and Dark Energy. I didn't know about his devil method. That's why some computer scientists and engineers blame Quantum Mechanics for Classical calculations and measurements of Geometry and Algebra.

[@trudyandgeorge]

It sounds like you would enjoy Stephen Wolfram's latest work on the potentially computational nature of physics. Specifically the idea he has dubbed 'computational irreducible complexity'; these classical bits, black and white as they are, produce behaviour that is fundamentally impossible to predict. Not simply difficult like the chaotic nature of some systems, but impossible.

[@oldfatbastad6053]

[@techcafe0]

I sometimes find the background audio tracks to be way too loud, especially compared to the voice narration, making it difficult to follow along. Please keep this in mind for your viewers, who'd like to HEAR what's being said, and not so much noisy background distractions. Thank you.

[@katarinajanoskova]

I don't think they have much say about this. Many of these are not exactly allowed to be shown on youtube. If they had the original soundmix, I'm sure it would sound perfect.

[@RWBHere]

@@katarinajanoskova No, trust me; I've heard the same racket on almost every recent UK and US TV broadcast which can be received from originating broadcasters in Britain. An additional annoyance is a continuity announcer shrinking the closing titles which contain useful information, whilst talking over what might be the only piece of desired music in a programme. For me, the result of the foreground music and noises is a big turn-off. I rarely watch TV nowadays, other than live events, because of the constant and stressful noise bombardment which is inflicted upon viewers. And there's no way for viewers to turn it off so that they can hear what is being said. Anyone who has tinnitus or another hearing difficulty stands little chance of learning from anything which is being said because of the often pointless 'music' and other noises which have been added to the broadcasts.

[@chaueter1041]

That’s interesting, maybe it’s my ADHD, but I love the background music. It actually enables me to focus more on the words and simultaneously let my imagination fixate.

[@tonypap1]

I love these documentaries and Jim is one of THE very best. But I do wish the writers would think of something different to say at the beginning of these documentaries other than...."this is the story of......"

[@cinemaipswich4636]

Professor Irving Finkel is lousy at telling jokes, but he is a powerhouse of knowledge about how we first learned how to write. Along the way, we created a class of students that copied words to clay tablets and papryus, so that their teachers could grade them. Thereby those old stories of renown were oft repeated, rather than just said. Writing is the greatest invention of humankind. Alan Turing had great respect for Jacquard and his invention.

Fascinated by what the ancient mesopotamians felt about their new writing techniques. I’m wondering if it’s the earliest known usage of the phrase “These kids and their tablets” Possibly more remarkable is that their words for eye, dear and idea were all phonetically identical to modern English.

[@vordag]

where does the information come from?

[@Wizthings]

Surely, It was Professor George Boole's work that inspired Claud Shannon's paper. Boole was aware that his algebra could be utilised in machines. Boole stated he didn't have the skill or inclination to make these machines.

[@roytaylor2161]

Jim Al-Khalili makes a basic error of omission by missing out the music produced by rotating drums invented at latest by 1770 in Switzerland but possibly earlier, and which almost certainly gave rise to the development of punch cards. And then, to quote Science Direct: The Babbage Analytical Engine, 1833, is considered the first steam-powered computer. Charles Babbage is considered by many to be the 'Father of the Computer' and his assistant, Lady Ada Lovelace, the 'First Computer Programmer' because she wrote mathematics problems for Babbage's machines. A conceptually much larger leap than Morse Code as the intended design allowed for the computation of 1,000 stored numbers with up to 50 digits, something not achieved for another century! How were these most basic facts missed out?

[@robkeeleycomposer]

I totally agree - I guess, to be fair, there would be the usual time constraints, and I suppose there are out there quite a few docs about Ada and Babbage: it's still a damn good programme I think - I sure learned a lot.

[@Uvisir]

and what about george boole?

[@bittertruth6575]

He never actually built it. The one's you see in the museums etc were built in the 1990's to honour his 200th birthday. Also Ada alludes to Jacquards punchcards when she envisaged the 'programs' for the analytical engine: "In this, which we may call the neutral or zero state of the engine, it is ready to receive at any moment, by means of cards constituting a portion of its mechanism (and applied on the principle of those used in the Jacquard-loom), the impress of whatever special function we may desire to develope or to tabulate. These cards contain within themselves (in a manner explained in the Memoir itself, pages 677 and 678) the law of development of the particular function that may be under consideration, and they compel the mechanism to act accordingly in a certain corresponding order." (Scientific Memoirs/3/Sketch of the Analytical Engine invented by Charles Babbage, Esq./Notes by the Translator, Augusta Ada Lovelace) Also look into the Banu Musa brothers (9th century) for "the earliest known mechanical musical instrument". It was a hydropowered organ which played interchangeable cylinders automatically. According to Charles B. Fowler, this "cylinder with raised pins on the surface remained the basic device to produce and reproduce music mechanically until the second half of the nineteenth century."

[@deep-insight]

Very insightful again 👍 It intrigues to think that destroying information increases entropy… I would have wondered creating and maintaining would also increase the entropy elsewhere in the universe. Nonetheless, it makes literal sense that deleting info will increase entropy, as it is hard to change habits as quite literally one’s world seems to go in a disarray while changing habits 😉

[@richarddeese1991]

Thanks. Unless we invoke magic, the partition takes energy to open & close. tavi.

[@mellertid]

Yes! But what I personally don't understand is how that energy cannot theoretically be smaller than the gain from the sorting of the molecules. I believe it, but I don't get it.

[@fluffykitties9020]

Reminds me of the old BBC documentary series by James Burke, "Connections". There was an episode on this very topic. Check that one out too, in some ways, it's better. This one was has too much music/drama/meaningless video footage filler. It does make some new interesting points though.

[@joetoocool]

Why didn’t Jim mention the Babbage Analytic Engine and Ada Lovelace who wrote programs for it? Or did I miss it? They lived in the 1800’s, long before Turing. There’s even a programming language named after Ada. They should have gotten a mention. In my mind, this is a big miss by Jim. I hope someone can explain why they were omitted. He must have known about Babbage’s work.

[@davidkantor7978]

Maxwell’s Demon is not going to work. 1: how will it know when a fast-moving molecule is approaching? Shine light on it? That would knock it off course. 2: when the demon opens the door to let a fast-moving molecule go from right to left, he needs to do that at a moment when there is not a molecule on the left side, that would pass through to the right. As the left side gets hotter, there are more molecules there, moving faster. You’re not going to find a moment when there isn’t such a molecule on the left - at the same moment that a molecule on the right is heading toward the door. As the left side gets hotter, the demon will need to wait longer and longer for the right moment to open the door. The wait time could grow without a limit; I like to say that it will eventually be a thousand years between when those moments occur. It’s similar to trying to make a left turn onto a busy two-way street. (Right turn for those in England.) This is also a microscopic view of what is meant by Pressure.

I do not know what he is talking about, but he seems to be very confident about what he is saying. If Lyon France could make such beautiful silk patterned fabric so easily by using punched hole in thick paper then France should have dominated the beginning of the Industrial Revolution in the first-half of the 19th century. But it was England who dominated industrial manufacturing beginning in the 1830s with mechanized looms making blank pattern cotton fabrics. But I do remember attending undergraduate college and those math majors with their stacks of fortran cards. Those early computers read the fortran cards and executed their commands. So I am confused.

[@BradleyLayton]

The Fortran cards calculated standard deviations, growth trends, anything a Turing Machine could compute. The looms were single-purpose "fabric-pattern computers."

@ 44:15 _" In this paper Shannon did something absolutely incredible. He took the vague, mysterious concept of information and managed to pen it down. Now he didn't do this using some cleverly worded philosophical definition. He actually found a way to measure the information contained in a message. "_ @ 44:37 _" Amazingly, Shannon realized that the quantity of information had nothing to do with its' meaning. Instead he showed it was related soley to how unusual the message was. "_ There is something fundamentally wrong with these claims. They're contradictory to one another. Also, fundamental constants and the mere concept of Occam's Razor fly in the face of it.

Completely adjacent to anything I was talking about, hence why you could replace " penned " with " pinned " into the quote and it would not change the validity of my argument one bit.

[@homomorphic]

To be clear. Turing was not the originator of the idea of separation between instructions and data. Charles Babbage and Ada Lovelace absolutely understood the difference between instructions and data. Not saying Babbage or Lovelace are the origin of the thought either, I don't know who is, but whomever it was they absolutely predated Turing.

[@BradleyLayton]

Turing formalized the mathematics.

[@homomorphic]

@@BradleyLayton wrt to processors, Turing distilled the information theory. Babbage, for example, was building an actual machine and wasn't too concerned with the abstract nature of information theory, but he certainly understood the concept of instructions as beimg distinct from data. It was Von Neumann who later proposed that instructions and data (although fundamentally different in the information model) can be stored in the same physical cells.

The expenditure of energy happens with both the processing of thought, whether accumulating OR deleting information, AND the manipulation of the box. It's like using an inapt analogy to describe the mechanics of an actual principle.
