    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. ( )

      tiny thing: about the salt audiobook, the garum you mentioned is essentially salted fish paste that was "cured" and transported in big amphoras, it would preserve itself very nicely. It also existed before the romans, as far as i know the phoenicians brought it to west southern europe from the middle east around the 8th and 6th century b.C.

                So in theory you would only need 1 modern smartphone to fly a rocket to the moon? They did it with way less computing power.

                                  It's insane to think they were capable of all this in the 60s and were having such a hard time trying to do the same with waaaaay more advanced technology.

                                              That's what I find amazing about old technology. It's hard to understand these kinds of things, but it is so much easier looking at old tech. When somebody says memory stores data, you get a general idea, but seeing physically woven magnets to act as data storage makes it really amazing. It's also why if you are interested in computers and how they work on a physical level, one way to get a general idea is watch Minecraft Redstone builds of ALUs, CPUs, etc. Closest thing you can get to working on the transistor level without being rich, haha.

                                                        That's a great video, I recall "Curious Marc" had his mates trying to get the Apollo computer to work, they had issues with the core memory but they worked through it, so far they've made 26, parts it's so interesting

So even after years turned off, the data is still there. I used to have a PDP-8/A and I found my program in the core memory after many years. You might be able to actually read what you have in your hand here.
