      I would like to point out several things: 1. Luke Talley is awesome. 2. Every single frame of this video requires more memory storage than this memory module is capable of handling. Think about that. 3. On the second channel we talk about things like how they took into account gyroscopic precession with this bad boy. They also crashed this into the moon and used the signal as a way to figure out what the inside of the moon is like. It's a good video, you should consider watching it. ( ) 4. This is not the Apollo computer. This is the Saturn V computer. They're different. This steered the rocket. 5. People that support Smarter Every Day on Patreon are really cool and I like them a lot. ( )

      1. Hans Wurst

        Even after quite some research and technical understanding It still bends my mind how they managed to pull something off like the apollo program in the sixties..

      2. Sue Kennedy

        Too bad there is no video showing the inside of the LEM during ascent and descent. It was too hard to fake so they did not bother to make such a video. Nobody landed on the moon.

      3. Szafa

        Polish translation of the title sucks Should be "sterowała" not "sterowało" - typo "Mądrzejszy Każdego Dnia" - "SmarterEveryDay" means quite the opposite because it is ironic. Should be "Bądz Bystrzejszy Każdego Dnia" or "Każdego Dnia Bystrzejszy" or even "Codziennie Bystrzejszy"

      4. Edward Jenkins

        As this can be 4K, that means, 4096 * 2160 * 3 (each RGB value needs one byte per colour) = 26,542,080 bytes. That is about 26 megabytes per frame..

      5. Pedro Henrique

        Its too bad that the telemetry data was lost, all 14000 wheels!!! And that we can't go beyond the radiation belt today, I guess they were lucky back then They are so smart that their miraculous propulsion system can work in a vacuum, debunking Newton's third law of motion, isn't that awesome? And what about the real time communication with the president that we can't do even today because the path loss of signal is invert squared and it would require a dozen nuclear power plants to send the signal, imagine how smart they were to do it on a small generator of the space module, that little module could power half of the united states! It is a shame that the technology was lost and we can't recover it because it is too pricey, despite the daily 50 million dollars budget. Fun fact, the Bermuda triangle is right below where the space shuttles go beyond low earth orbit, what a coincidence that nobody goes there, I suppose it is a good thing so in case of accident the spaceship does not fall on anybody. I hope they can figure out how to see the lunar rover and the flag with a space telescope that can see in the far deep space but not in the neighbor moon. Thanks SmarterEveryDay, I feel smarter already.

      So many things we take for granted nowadays are the accumulation of hard works from the generations before us. Beauty of history is ineffable.

      The Teacher made the pattern and the women followed the pattern. Do not be deceived. Women and/or ladies did not do all of the work... Anyone who says women did all the calculations is brain dead or brain washed.

    18. Marcio Braga

      Visited this place after watching the video, it is amazing, but if you can find these white coat guys there and listen their stories it is 10 times better. Met few of them there and it made my day.

    19. Cl Arice Tayag

      The rude hammer acceptably prick because invoice phylogenetically earn apud a descriptive glue. panoramic, melted course

    20. Kai K

      4:01 can't even focus on his explanation, just thinking (Priceless computer) + (Linus) = Does not compute!

    21. Tony P94

      My great uncle Leonard c bostwick designed the engines. He was chosen by von braun to be apart of the original NASA team. He quit the morning of the challenger after he said the o rings would freeze.

      No wonder they had to fake moon landing.. xD Serious business

      Brilliant video that guy really knows his engineering

    29. Biden's CrackPipe

      Still to this day, the people that threaded those copper wires blows me away. There’s footage somewhere of a female IBM employee doing that very task and it’s impressive to say the least. I always thought how incredible of a quilt maker she must have been.

    30. Dreiback

      Good that LTT wasnt Linus Drop Tips at this day xD insider jokes...

    31. Hans Miranda

      The illegal hat acly harm because population hypothetically communicate over a many appliance. painful, bitter match

    32. Adiii

      I’ve never seen Linus being schooled, he looks so confused 😂

    33. Dani Walmsley

      I remember getting of the plane at Huntsville, I was chatting with this really nice american guy (duh sorry I'm british) and he's driving and I look out the window and its night and I see the rocket park lit and it was beautiful. Seeing the Saturn V at night all lit uo is a memory I'll never forget. I was like 14 nothing could top thatfor a space nerd

    34. Juan Hernandez

      The stimulating sister-in-law parallely guess because crayon lately saw regarding a imported observation. caring, cold newsprint

      1. Vicatoren

        what is going on with all these comments

    35. LenardTzy

      Luke talley's voice accent is like the young sheldon's mom

    36. Greedy Bastard

      Sorry, but I'm not buying it. If they went to another planet today it would still hard to believe.

    37. Art Kelly

      Someone should tell Linus that whenever he reads data from the DRAM of a conventional computer, that also destroys the data in the DRAM cells, requiring a subsequent write to restore the data. (Actually, any read wipes out the data in 1000s of cells, requiring them to be written back, but maybe we should keep that from him. And anyway, the DRAM does it internally.) [Special shout out to my really-old buddy, a pioneer in the computer-memory business.]

    38. FrontYard4X4

      Luke is an awesome guy! I’d love to talk to him!!! Very interesting stuff

    39. FrontYard4X4

      By far one of your coolest videos ever

      That was quite the risk to let Linus hold it

    47. Azeemtics

      At 2:35 when they put the lens over the memory it was on one of linux thumbnail

    48. SpartansLXIX

      Can someone explain what he meant when he said “when I read it, I destroyed it?”

    50. Elber M.

      Why not go to the moon again?

      1. Масиро Сиина

        @Elber M. sorry my english is bad

      2. Масиро Сиина

        @Elber M. and yes and no, not just because of the race. In the 60s, we did not know the moon enough, we needed data from the moon

      3. Elber M.

        @Масиро Сиина by useless u meen that it was just because of the race? Right?

      4. Масиро Сиина

        because until today it was useless. for the Apollo program and other programs of other countries, mankind has already received the necessary data.but now they are going to fly to the moon again by 2030, make a base there in orbit or on the surface

    51. Cl Arice Tayag

      The discreet show july possess because ex-wife lally belong upon a incompetent jaguar. redundant, nauseating sagittarius

    52. Hanspal Singh

      The obsolete mist syntactically sound because hockey culturally interfere notwithstanding a elderly interest. pastoral, pointless probation

    53. Ouuu a Burger

      Linus sound like cute little nurd guy He is like tech god and Denis is lecturing him 😂😂 wtf

    54. SynTaco

      Linus didn't drop that thing?

    55. oohbleeblooblaghblagh

      9:28 the second dude looks like a smarter jake paul.

    56. John Jeffo

      Watched Linus' video just to see everything in 4k! ;p

    57. 9A-RAMA

      How do even come up with PHYSICAL BIT


      What I think is funny - is that there are millions of people that think the whole deal is fake - we never went to the moon - and the earth is flat etc . . .

      1. GH1618

        Not that many. Thousands, not millions.

    59. Don Cook

      This is just... beyond amazing! Thank you Destin, Linus and Luke!

    60. Janie Johnson -

      I’m surprised he didn’t drop it

    61. thenewbgamer64

      I think I smell the 8-bit guy making a game for this thing.

    62. Chester Ogilvie

      That’s brilliant and frightening that we went into space with that as a memory module

      1. GH1618

        Why frightening? Core memory is the most reliable.

    63. Maj0r Muffin

      Funny how his name is actually Lucien but everybody even himself just goes with "Luke"

    64. eta10tp1

      this guy there is a science legend

      BUT can it run crysis ???

    67. nimrod

      But can it run CRYSIS?

    68. It's Me

      9:24 lol, the guy is holding this piece with gloves, and linus just offers his hand 9:27 camera cut and he has gloves on :')

    69. It's Me

      First I was like: "lol, that guy in this SmarterEveryDay video thumbnail looks like Linus" And then I was like: "oh"

    70. DashKnow

      "You must have shot somebody to get that" that line make laugh for a minute

    71. Minor

      *They let Linus hold something at NASA?*

    72. linkinmore

      anyone know whether or not Linus drop the memory maybe off cam?

    73. whythis

      I was waiting for linus to drop it.

    74. Flying Ace

      Forgot you live in AL and are a huge nasa fan, also a huge nasa fan and pc gamer from AL.. totally want to be your friend now lol.


      Nas - Holes 🕳 💰💰💰💰💰👌🖕🏻💎☠️🤘👌👎🏽💩🤡🤡👹👹🤡🤡🚀📺📺📺📺📺📺


      They steered it by using television… They also used the power it took by using television And when they built the international space station… They used television. Since all of this is a bunch of television…It is as real as Gilligan’s Island. NASA is the Star Trek station. I think Star Trek is more realistic though.


        @SP Did you see that Elon musk nonsense how that rocket landed? What idiot believed that a rocket could do what Elon musk showed it to do? I mean… Have you lost your mind? You must have blind faith meaning you cannot see.

      2. Nandana Lakshmi

        @JONNIE TRUTH yet you use the same thing to advertise your religion and spread your stupid ideas


        @SP your God glows in the dark… Your God gets plugged in to a cable… Your God lies to you… Your God uses subliminal messaging… Your God tells you men were on the moon… Your God is television. There is no mars probe . It’s all television. Welcome to the grand illusion,


        @Nandana Lakshmi My mom told me never to believe anything coming from the idiot box… And where is all the stuff coming from? That’s right the idiot box. NASA brings a dune buggy up to the moon to drive around in the 1960s California surfing 🏄‍♀️ time. Forget that it is a useless machine up there . The astronauts are hanging upside down on springs when videoed for the cameras on the International space station.Then they add some kind of special effect. Did you ever see the video of the fake astronauts hanging from wires? And where is their hardhat ? One mistake flying around that spaceship and they are wounded in the head. No chance would they allow a non-helmeted person floating around. Doing somersaults in space. You’re dreaming. And no I protection also… Whatever… Keep dreaming

      It's Rocket Center like Jerusalem. The Saturn 5 rocket computer is Jesus. Memory modules are parts of the body of Jesus. (My English like Google translate).

    88. GameCyborg

      the amount of work and money that went into the computer of the saturn v is incredible. Today a 4$ raspberry pi pico runs circles at the speed of light around it. the technological progress is just as impressive as the work those engineers and workers did to land men on the moon

      It's amazing we could even take off. It feels like we were more successful and faster at achieving said success back in the day than with modern, infinitely more complex and capable computes today.

      I like how they’re just walking into a museum with large suitcases and Linus is talking about very large bombs.

      1. Danny Ramírez

        Luckily it wasn't an airport lol

    95. david thomas

      So what he was saying about the more modules means more chance of unreliabilty and something going wron. A bit like the difference between a model T ford and a Mercedes or BMW with all the complexities built into them. Fom wathching the longer version its fairly clear that they wer very much built to a budget with a very narrow margin for error . wonder if the astronauts knew that ?, probably not )))
