    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. Cheers, A future archaeologist.

    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

    When you see this you start to understand how Nasa can say they lost the technology to return to the moon. They're really saying we'd have to invent this all over again...

    so the sad truth is that they didn't have to rush out competitor countries to the moon and wait a few centuries to develop a decent computer that would allow them to go even further than the moon? Oh man that human-ish pride is just causing headaches and serves noone any good.

    When some one asks... "How can you forget how to get to the moon?!?!".... this is how.... so, fewer and fewer people are around that built the rockets and computers that sent man to the moon, tech has been lost and or cannot be made anymore since it is obsolete and on top of that many of the notes, adjustments and field modifications that were made are also lost to time and history..... so yes, it is possible how to forget to do something like getting to the moon..... so, these days you have to start from scratch

    NASA's dun goofed. They could just strap some RGB leds on that memory module to instantly get triple performance.

    No, they didn't program the computer by threading the cores. That's B/S. It's RAM! But its totally static. 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.

    That is probably why you'll never meet a computer scientist from back then that doesn't work glasses.

    The Navy was still using core memory in its air traffic control systems in the early 90s. I was electronics tech back then and I knew the AN/TPX-42. It had 64 kilobytes of core memory. My home computer back then had more memory.

    Hi, I remember when I was a child having a Casio calculator watch. I had a teacher tell me that it had many times the memory and I think computing power of the computer that took space ships to the moon. I can remember trying to imagine how that could be, now I understand 🤓.

    This video showed us how computers were put together in the 60's, but it never explained how the data was delivered to the programmer and it never answered the question that is in the title of the video, how did NASA steer the Saturn V? A car driver uses his inbuilt human perspective to determine the speed of the car and looking ahead determines the direction he wishes the car to take, so he turns the steering wheels which turn the car wheels to take the car in the appropriate direction. So what components were used to change the direction of the rocket and how did the rocket get thrust while moving in a vacuum?

    So, I guess my only questions would be: a) What kind of over-clocks did NASA achieve on that thing... & b) Undoubtedly most important... could it run Crysis
