    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. ( https://youtu.be/6mMK6iSZsAs )
    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. ( https://www.patreon.com/smartereveryday )

      Flearther McPlane he actually knows we didn’t but is too scared to go against the grain. He used to have a video with all kinds of proofs we didn’t go. But his nerd fan base that keep him paid , persuaded him to remove his videos and follow like a good boy. He’s a sellout..

      Dr. David Banner F.E.S. I asked the same question. Lol Except I accounted for a torr 10 and the magic O-Rings used in the Cupola. Don the lousiest liar Pettit. Dude gets caught lying all the time and acts like a deer in headlights. Lol

      SmarterEveryDay what happened to your epic videos confronting the nasa lies? Like magic O- Rings and Van Allen Radiation belts or create one with the physics needed to achieve a quarter million mile trips fuel ratios and needed oxygen tank space plus heat and radiation deterrents. Effects of a vacuum of torr 10 on thrusters or ignition sources.. is a firmament really too far fetched? Considering the Sierra Leone sky stone or Libyan desert glass..

      Why would you succumb to the peer pressure of fake space. I honestly lost a bit of respect for you taking down your videos of nasa lies. Now you’re riding the train of lies because you don’t have the balls to stand for what you know to be true. If it’s all fake and God is real, where do you stand when judgment calls? With the crowd of people that believe everything they are told to fit in? Shame on you for choosing the wide road to destruction. You could have been the deciding factor in someone’s salvation...🧐

        LMAO! Still trying to reinforce the Moon hoax.
        The rocket went ''''''splash'''''' in the ocean. No one was on board and that's - the end!
        ...or the beginning of the same practice which has retarded people (self prescribed intellects) thinking we actually go to the imaginary place they call, "SPACE"...
        You should rename our channel to, "Dumber Every Day". It's far more appropriate!

                                  Typical space videos by nasa, real life money loss, aka launching rockets into the sea with no humans, then cgi all the way till they end, last but not least recycle rocket from sea and repeat.

                                        so I found a cool science anomaly that I haven't seen before and I searched it up and can't find it or an explanation. if you take a 2 by 4 block of aluminum and you put it on its side, so the short side is facing up. then if you slightly slant the block and roll a cylinder magnet down at a slight angle it will seem to bounce off the side of the wall as if there is an invisible barrier.

                                          At 2:00, you are describing "core" memory, which was the type of memory used in most computers up to around 1975-1980, when semiconductor memory first entered the scene. I worked on an IBM 1620, a 1401 and others, including a minicomputer made by a company called Microdata, which all used core memory. (I'm 72.)

                                          I still have three 8K memory boards from that Microdata computer. (Failure of this type of memory was common, so I decided to save boards when they were replaced.) I remember they were priced at $3,500 each back then, or around 5 cents/bit. At that rate, 16GB of RAM (128 billion bits), now commonplace in PC's, would cost 6.4 billion dollars (without accounting for inflation)! That's over double the entire Apollo program budget. (Good thing they didn't need 16GB.)

                                          Just as shown in this video, I can see the little cores arranged on the grid of wires. I was amazed back then, and I still find it impressive today. Here's an interesting fact about core memory: In order to read a bit, the computer would actually write a zero at that location. A sense wire running through all the bits on that plane would detect a pulse if that location originally contained a 1 because reversing the magnetic direction would induce that electric pulse. A second cycle was then required to restore the bit back to a 1 (or leave it as 0 if no pulse was detected). This was known as "destructive" read, requiring two machine cycles. One cycle on the Microdata was one microsecond (1 MHz). A modern CPU running at 4GHz is 4,000 times faster. But one cool thing: if the computer lost power, core memory was preserved! It wasn't 100% reliable, but often, when the computer was powered back on after a power failure, it could continue running where it left off!

                                          Anyway, I am wondering what to do with these memory boards. Right now, they're just gathering dust in my closet. Any ideas?

I remember getting up early in the morning in the 1960's to watch a rocket launch on TV and it was an amazing feat back in the day. To see this "computer" that made that happy is mind blowing. These guys were amazing and it worked. Thanks for this very cool video.
