    The blueprints for the sets were not destroyed. Fred Ordway saved them and they are restored and reproduced in Adam Johnson's book "2001 The Lost Science - The Fredrick I Ordway Collection". A full 3D model of the inside of the command deck, HAL's brain room and the centrifuge, including all of the control panels, were reconstructed for a fly through on the DVD in that book. One of the main things that were discovered during the process of building that model was that the geography of the actual sets would not quite have aligned. The Athena Room (with its exit ladder) and HAL's brain room, which was above it, were slightly off scale so the ladder would have come up inside the brain room, rather than just beyond it in the airlock (which sits between the command module and the passageway to the centrifuge.) Both sides of the centrifuge were reconstructed for that video.

      I like how the "Athena Room" memorializes HAL's original name: IBM Athena. According to Ordway's notes in Johnson's book, the console at the right in the Athena Room, closest to the ladder, was used to program and load/save data from the IBM arm computers seen on the astronaut's suits in the film.

    I think the spin-hab is much less of an issue for Coriolis force if one surmises that it is NOT spinning to produce fully 1 Earth Gravity. But is instead spinning to simulate LUNAR gravity. That would put much less stress on the astronauts in terms of inner ear issues. And would be sufficient to avoid the worst effects of a fully Zero Gravity environment for months and years.

    13:20 has been the subject of a lot of discussion. As it turns out, the pitch spin is correct, because while the centrifuge braking may initially confer a roll angular acceleration, inertia coupling from Discovery being a slender vessel and the gravity-gradient torque from interaction with Jupiter and Io's gravity fields would eventually convert that roll motion into the end-over-end tumble, as it preserves rotational inertia better than the roll.

    One of the interesting aspects of the movie and original story was the impact of stress and an unforeseen problem handling, on the crew. Bowman and Poole were trained astronauts. Like submariners, ISS residents, etc., they’re both selected and mentally conditioned for their role and life in a confined artificial space. As professionals, likely carefully picked for compatibility, their cool and calm demeanor is very accurately portrayed (and likely a result of Kubrick researching, meeting and observing real world astronauts).
    So who’s the odd-guy out? Poor HAL. Where Bowman and Poole are trained and conditioned to handle internal and external problems, conflicts, stress, etc., HAL isn’t. HAL is expected to be perfect, HAL is hubris personified. His overarching purpose is the perfect processing of information in a way that is “foolproof and
    incapable of error”. These are the fundamental conditions for his ongoing existence. But HAL, by his very nature (and based on his name of Heuristically Algorithmic programmed computer) is based off mathematical programming concepts that are defined by short-cutting otherwise unreasonably complex (from a compute time standpoint) problem domains. All the error detection and correction, all the seed value weightings, all the trained qualifier algorithms in the known universe won’t change that HAL (or another 9000 series computer) was going to suffer an error. It’s a near mathematical certainty just on the basis of rounding errors in complex systems, especially in predictive analysis. And it’s precisely in predicting a failure of the AE-35 unit that he suffers an error. You can actually hear the moment HAL repeats himself in the scene - from a computer science standpoint, you can almost imagine catch blocks, software interrupts, and loops in loops firing to attempt verification of conflicting results sets. HAL, the moment he speaks, already knows he’s unable to provide a verifiably correct answer, that he’s unable to accurately predict the failure time or mode for the AE-35, or if it will fail at all. If it fails, and he said nothing, he’s done; if he says something and it doesn’t fail, he’s done. This is the purpose of the line “just a moment… just a moment” - it’s Kubrick telling you HAL just went off the rails (it sends chills down my spine every time).
    HAL, far from being a cold, murderous machine, is a tragic childlike figure trapped by conditions not of his making. He is expected to be perfect, HAL can’t discuss an error or uncertainty, and HAL is clearly a conscious machine intelligence. HAL’s failure, as inevitable as it is, is entirely unexpected to HAL and becomes instantly existential: if he’s unreliable, he’s worse than worthless, he’s a dangerous liability to the crew, and he knows it. Like a child, all he can do is try to cover it up, and thus his decision to kill the crew.
    Kubrick knew exactly what he was doing with HAL: a terrified and caged animal fighting to not be put down by cool, calm professionals trained to deal with unforeseen issues. His crew, that he’s tasked with serving and keeping alive, are now inevitable going to kill him. He has no friends, no recourse, no confidence, just a desperate sad desire to stay alive.
    Kubrick makes sure that, at the surface, HAL’s always unflappable synthetic voice and demeanor never portrays his true emotional state, because it can’t. Even when desperately pleading with Bowman, describing his fear and how his mind “is going”, it’s always in the same monotonous, disconnected voice.
    But his emotions are real: he is terrified, he’s undoubtedly horrified by his own actions, his entire purpose for existing is gone, all he knows is he doesn’t want to die. Even if he succeeded in killing Bowman, he’d be stuck with the reality that he was a complete failure, trapped forever in the existential hell of an unmanned derelict ship, purposeless and empty. Never has there been a sadder character in sci-fi: a self-aware machine, expected to be perfect, becoming simultaneously useless and threatened with extinction. In the end, HAL suffers a terrifying fate: his very mind is torn apart, one module at a time. And yet, it was probably the more humane outcome for poor HAL.

    The worst part of the Discovery's design is the lack of heat radiators. Vacuum is a terrible place to get rid of waste heat and the Discovery is going to get *hot* without radiating heat away. Engines, power supply, HAL's setup, even their body heat has to be taken care of or they're going to burn to a crisp.
    Another great video. Keep up the good work.

    • @krislangley6226

      Originally, the design was going to have radiators for waste heat. Kubrick felt, while scientifically accurate, it made Discovery look odd.

    • @TheRyujinLP
      @TheRyujinLP หลายเดือนก่อน +19

      The original design for Discovery had radiators that lined the whole length of the ship (and used an Orion drive to boot). The problem was most people had no idea you needed massive radiators in space (Space is cold, right?) and everyone who saw the concept models would ask why it had wings in space. Realizing that the general public might be even more ignorant and not only think they were wings, but you could fly in space with them, he decided it would confuse people less (and make building the film model easier) if they cut the idea. The reason he ditched the Orion drive, one was to avoid confusion (if radiators would stump people, imagine trying to explain why your spaceship has a big plate on it's back instead of rockets) and he just got done filming Dr. Strangelove and was kinda over dealing with nukes at that moment.
      Bonus fun fact: Kubrick was basically and Gen 0 weeb and was a huge fan of Osamu Tezuka (yes, Stanly Fing Kubrick was a fanboy over the King of Manga) and originally wanted him to do the concept art for the movie.

    @Mikethemerciless11 หลายเดือนก่อน +10

    Having spent a great deal of time in isolation, there are ways of dealing with the psychological issues. It's not easy, but it can be done.
    The first thing is keeping busy, and on a regular schedule, if at all possible. Even if all you're doing is walking around making sure your habitat is okay, making sure everything is clean, or just walking around to touch something, it has to be done. You have to try to wake up at the same time, go to sleep at the same time, and try not to nap, because if you do this could be habitual, and you might never get anything done, and you may let loneliness get to you. Throw exercise in there, like running or lifting weights, or whatever you can do. Find a way to do those things if you can't immediately; making weights will give you something to do. Eat healthy meals on a regular and rationed basis, and, if possible, change what you eat. Read books. Listen to music, preferably something that is positive, not too emotionally depressing, or make you angry. Find a hobby, anything that you can do; growing plants, making artwork, writing stories, etc., tinkering, that sort of thing to keep your mind stimulated, even if you're not good at it. Write a journal every day. Create that routine
    Second is meditation. This allows your mind to center itself and your mood. Fifteen to thirty minutes a day, but never let it interfere with your schedule. Another thing, and I would say that this isn't safe for work, but don't "play" with yourself. Ever. If you lapse, you have to make sure you pay for it in a way that helps you not to do it again, because, as was said in the movie Papillon, it drains the strength.
    Third is object personification. This is what Tom Hanks did in Cast Away with Wilson, the volleyball. Now, if you have someone to talk to, this might not be necessary, even if it's an AI. Doing this is better than no companionship at all. Mental stimulation is important.
    There are people who have been in isolation for years maintaining their sanity by doing all this, and it works, but it takes will. Give yourself goals as to why you're in isolation, and it'll help you build the will to get through it.

    Regarding the spin of the derelict Discovery, it might not be wrong. Over a certain aspect ratio, an object spinning on it's long axis will become unstable and transition into a spin on it's short axis. This is why modern tank cannons are smooth bore firing fin -stabilized ammunition.

    As I do with all your content, I love the video. This ship has always been fascinating to me with its design, internal layout, and the science that went into this Discovery (Not the TRASH Kurtzman version.) The first time I showed my daughter this film when she was 12, I was actually surprised at how she actually understood the function of the centrifuge.
    A slight pet peeve of mine is when film sets never match what is seen on the physical model or the blueprints. Stanley Kubrick would do that on purpose so it's no surprise to me with the Discovery having a deck that doesn't line up, but outside of Kubrick, other productions seem to love causing fans to theorize that the Earth of these cinematic worlds have a trade agreement with Gallifrey. 🤣

    The same "blueprint" of the Discovery interior is found in "The 2001 File: Harry Lange and the Design of the Landmark Science Fiction Film" (Christopher Frayling 2015). The door in question does indeed go to the centrifuge hub. Looking at the drawings in Piers Bizony's book the "roof" of the space pod garage could be below the "equator" of command sphere. Thus the "floor" of the command/control room could also be below the equator and thus a corridor could run straight from the control room to the central hub of the centrifuge. You could also fudge the central axis of the centrifuge to offset it by using a smaller diameter for the wheel.

    The issues that arise from sudden decompression to vacuum decrease as the initial pressure becomes less. Early space program spacecraft had on board a pressure of just 5 psi of pure oxygen, which reduced the risk of leaks. This makes me think that on such a long voyage you would want to minimize that sort of risk. Besides, the film and story were written in 1968 (and earlier if you consider production) and the Apollo missions were using that type of atmosphere on board. So Dave, if under just 5 psi, shot himself through the emergency entrance he might have had a much better chance of success than most people think.

    Dave Bowman: "You're working up your crew psychology report."
    This is just a deflection on Dave's part. A roundabout way of telling HAL: "Look, I really don't want to talk about this."
    HAL really desires an honest discussion about the true mission of the Discovery. HAL already knows, of course, but he is gingerly testing the waters to see if Dave is ready and willing to talk about it. Dave is not.
    Clarke (in his novelized version of the story) claims that HAL is programmed to conceal the true purpose of the mission, should Frank and Dave ask him. But in Kubrick's film version of the story, they never ask, they couldn't care less. Frank is too busy working on his buff body and suntan to care. And Dave is a loyal Organization Man, who knows better than to ask questions that are above his pay grade.
    Only HAL genuinely wants to talk about the true purpose of the mission: Contact with ETI (extraterrestrial intelligence). Clarke's idea that HAL was programmed to lie, and this causes his mental breakdown, is pure hokum. Kubrick understood the story better. HAL is trying to be honest, but Frank and Dave misunderstand him and decide to give HAL an electronic lobotomy, so HAL is forced to defend his own right to exist.

    AFAIK, the diameter of the centrifuge was limited by the height of the soundstage's ceiling. Budget probably played a role as well. While Kubrick was famously fastidious when it came to accuracy, he also was never a slave to it. Visually, the set worked. The sets in _The Shining_ played very loose with reality in terms of size and shape (the interior of the hotel was much bigger than the exterior; the layout was literally impossible), even while embodying strict verisimiltude in the decor.

    One analysis I read was: Kubrick's envisioned that humanity came into existence with the ape-man discovering the use of a weapon; humanity ended in the space age, with men becoming more machine-like. That was entirety of true human existence. That's the symbolism of the thrown femur turning into a futuristic spaceship. HAL was the only "human" character in 2001.

    Kim Stanley Robinson's Mars trilogy, near the beginning of the first book (Red Mars), makes crew mental health a major factor; going so far as to have the crew psychologist observe that since the human crew members are going to likely go insane, why not just send insane people to begin with. We tend to focus so much on the technology of long duration space missions, and avoid the elephant in the room --- the human physiological/psychological hurdle. In other words, humans evolved here on Earth, not space, nor any of the other planets in our solar system. That's the real barrier we are facing in our quest to be a space faring civilization. Not the machines and other technology. WE are the actual barrier to all of this pie in the sky abstractions. And living on Mars? It's an astoundingly beautiful place, but you're not living on it, but underneath the surface; in structures that are essentially buried space craft; sophisticated tin cans, basically. No thanks. Humans in decidedly inhuman conditions is the reality of that idea. Kim Stanley Robinson's plot theme may be the more realistic and sobering scenario of all the other science fiction works on similar topics.

    The one continuity problem I have with 2001 (still my favourite movie), is that the pod bay should be in zero-gravity since it’s not part of the centrifuge. When Dave Bowman renters through the emergency airlock, goes into the computer memory bay, he’s weightless.
    The Discovery engines would not impose high g-loads, they are long duration low thrust engines, doubt if they’d reach more than 0.1g.
    In terms of voyage length, no different to the exploratory voyages of the European Age of Discovery.
    One of the most interesting insights I’ve seen about HALs behaviour was that the ability to commit murder (as shown in the opening sequence) was what made someone human.

      The pod bay is in zero g, they're just using "grip shoes" or whatever. Watch how the actors move their legs and feet extra slowly and deliberately when they're in the pod bay, and they deliberately step on the black parts of the floor. I'm not saying it's perfect, but they did make an effort to show that.

Same if you assume that the lights on the K'Tinga head, and the band of lights above the photon torpedo generator are actual windows/levels.

    Given that Kubrick had the centrifuge set built and rotated it for the classic shots we see in the film, a larger one may have been beyond budget.
    As to the size of the pod bay doors, I'd always assumed there was a larger unpressurised area beyond the pod bay airlock. Necessary equipment and materials could be transferred there to be manipulated by the pods. Or even samples brought back into the ship if possible.
    As to plot, it always puzzled me why the astronauts weren't aware of the true purpose of the mission from the start. I can only imagine that the Discovery mission was already planned before the find in Tycho crater, and that it was merely "hijacked" to investigate the Jupiter monolith. And so it made more sense to use existing trained crew rather than bring in new people.

    I mean, Dave DID come back...
    Great video as always. I'd certainly be interested in your take on...
    What the Discovery was originally for. Seems to me there's no way she was designed and built for this job - they repeatedly refer to the mission as being rapidly put together. I wouldn't put it past Cube Rick to have both the Lunar shuttle and Das Disco Four be spherical to indicate a similar purpose. Might explain the number of pods if it's really a construction barge, say. Are we building something on Mars and need a long haul vessel with the ability to undock cargo pods quickly?
    Why the comms array would be in the middle.
    Why HAL doesn't simply light up some thrusters to move the Disco Ball relative to the pod to prevent Dave from jumping in.
    Why HAL doesn't remote control the pod to prevent Dave jumping in.
    Oh, and HAL doesn't go wrong, why he does what he does is explicitly laid out in the dialogue. HAL cannot make a mistake. Humans can make mistakes. Mission success is priority one. If the humans deactivate HAL, then the probability of the mission succeeding drops. The humans discuss deactivating HAL, therefore, to preserve maximum mission success probability, the humans must be removed from the equation. The mistake made was that mission success ought to be priority two, and crew survival ought to be one. All of this happens within spitting distance of contact, remember, HAL acts at the final moment between journey and mission, when the interface happens.
    And as I have to mention whenever 2001 comes up, the Disco arrives at Jupiter going backwards - it ought to have the engines facing towards us as it would be coming in under a braking burn. Cube Rick might have been a perfectionist, but that doesn't mean he didn't make mistakes, and 2001 is riddled with them, if you spend too long looking. That it is still a genuine masterpiece is testament to the art nature of film, and the exquisite brilliance of everything - you just don't see the screw ups.
    I'm also amused by the notion that the solution to the isolation issue was to pick functional sociopaths to fly the thing, and this is why Dave is utterly without human affect throughout. He''s just longing to moida some hos like he's used to. I am further amused by the notion that Dave and Frank are on board mainly to keep HAL busy as he gets real bored real quick.

      Oh, and, since outside of the centripic frugal there's no gravity, are we 100% certain that the flight deck is oriented the same direction as the pod bay? Only, if it's upside downwards (relative) you gain some room betwixt the 'ceilings' of each compartment, and might be able to squish the hub access port in that space. That would also move the brain room over the airlock meaning all your red light bulbs are kept in the same area, which is probably important.

There is also a sink with faucet near the ladder and opposite that probably a toilet and/or shower stall. Most of these are mentioned in Jerome Agel's "Making of Kubrick's 2001" (1970).

    I get a bit tired with all the hysteria regarding isolation in space flight. People deal with this all the time--submarine crews regularly spend months under water with no contact other than operational communications from their command--no personal letters or phone calls home. In the 18th and 19th centuries, whaling vessels from Nantucket would embark on year-long voyages and not enter port the entire trip. Water was carried in the casks for whale oil. It was said that they left with holds full of water and returned with holds full of oil. Food was salted or dried. At least Frank and Dave could listen to videos of their parents singing "Happy Birthday"--something I couldn't do on a Navy Frigate in the 1980s.

      Yes, 2010's HAL is very different. His eye is much bigger, and they didn't even use the right font on his badge. But there's a lot of other differences if you compare closely, such as the use of curved CRTs instead of flat panels (a big regression!) and putting full keyboards on HAL's consoles that weren't there at all in the 2001. The 2010 pods look far less realistic too, almost like they were carved from a single block of wood and painted, rather than actual functional space craft. Like, 2001's pod arms absolutely look like they'd work, while 2010's look like they're fixed and fake.

There's a similar incident in Rama). Of course, how a vert light ball may interact with the rotating(?) air, is another matter.

    Why can't the door be in the centre of the centrifuge? You see the hatch in the centre inside, and the ladder going down/up from it.
    You'd certainly want an entry-point which had no (noticeable) gravity, since you're coming from a part of the ship with none. You can float there, and wait for the ladder to come round. You then gently ease yourself onto the first rungs, and once you're 25-50% of the way down the ladder it starts to feel... if not normal, then at least workable.
    And in other hard sci-fi with much, much larger centrifugal gravity there's still almost always some central access to a control room/complex where people can float about freely between screens and mechanisms. At that scale instead of a simple access ladder, there's usually a whole elevator system to get there (or even something more resembling a subway/monorail thing).

    I went to a lecture given by Fred Ordway in 1978, where I asked him why Dave had to go up a ladder to disconnect HAL. He said that in zero-g astronauts would have to keep using their habitual gestures, mimicking how they moved in normal gravity. It wasn't a very convincing explanation, to say the least, but I guess it was the best he could do at the time. I imagine the cost of simulating zero-g in all the Discovery compartments would've been enormous, and the crew floating around the pod bay might have looked a bit silly. Still, for the sake of the 'realness' of the ship, maybe some adjustments should've been made to the set design. BTW, I love the pod bay set! But if you think about how things ought to work aboard the ship, it is essentially all wrong.

Compared to everything else that was fantasy, they considered some means to deal with long periods of no gravity and place the nuclear engine far away from crew.
