Warm Regards,

  • 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. This is not the Apollo computer. This is the Saturn V computer. They're different. This steered the rocket. 4. People that support Smarter Every Day on Patreon are make all this happen. If you're watching this second channel video I realize that you're more likely to consider becoming a patron... therefore I will now provide a link in hopes that you consider it. ( )

  • This may never be read, two years later, but I am going to try. I train project/program management principles and practices to engineering teams on aerospace and defense programs (space craft, rocket engines, satellites, fighter jets, jet engines, yada, yada, yada)--Rockwell, Boeing, Lockheed, Rocketdyne, Pratt & Whitney, Aerojet, and the like. Every 10-20 years we have to train up a new generation. I've run across guys like this every so often (he is off the charts, however) that share amazing bits of knowledge about how things were done. and how we got to where we are today. So much of what we teach today comes out the Systems Engineering thought process that came out of these amazing, well, systems--I think. I was in absolute awe. My question goes something like this--this was so freaking complex, I can't imagine starting from scratch--how much of what was ultimately accomplished on the Saturn V program was new, and how much was, or was based on what had been learned before. The layers of learning, the generations of learning, the evolutionary cycles that occurred before, versus during, upon which it was built seems unfathomable. Was it, say 20% we already knew, and 80% we figured out because the objective drove, or required that much innovation and leaps in learning? Or was it the other way around, we already knew 80%, but just had to put it all together. Because what he talked about (and had in his head) is staggering!!

  • Ok I may be wrong about this but is this museum in Oregon? I may have been here before. Edit: Nvm, I guess not. In Oregon there's a similar museum that's next to the famous water park that has an airplane on top of it, it's also next to an airplane museum that has the famous Spruce Goose as the center piece.

  • Fantastic video, but I'm pretty sure Luke misspoke or misrepresented something when he was talking about 'every time you add a bit you double the amount of stuff' at 22:40. It sounded like he was saying that adding a bit means that you double the amount of 'computer' and physical components you need to operate, however, that's not exactly true. Adding a bit means that you double the amount of things you can represent, but you don't double the transistors or core memory or anything else. If that were true, that would mean that a 64 bit processor would be 4 billion times larger than a 32 bit one, and that's not true, it's more like 2.5ish times the size/transistor count.

  • I grew up near Huntsville in Cullman, AL..Luke Talley sounds just like my grandad who passed away a few years ago, accent and especially with the "oh dang those plus c's!!" part! Before he died I started hitting the record on my phone when he told his stories from being a Commando on Iwo Jima and I only wish we'd both started sooner...him telling them and my secretly recording. Now I have that spirit in Luke Talley who was just a bit younger and hence able to give me another piece. There is something special about those old Alabama men both of NASA and even in the woods....always amazed me the true genius dispersed in the wilds of Alabama in the most unlikely of places.

These people have worked tirelessly with often very crude instruments to make some incredible things happen. Great video. Learned a lot about how much technical knowledge went into the construction of the Saturn and Apollo mission spacecrafts. I am humbled.

I am an Apollo geek from way back and with videos like this can learn even more about the Apollo program, which is undoubtedly the greatest engineering endeavour in history. The ingenuity of the engineers at that time is truly extraordinary. Luke Talley has encyclopedic knowledge of the technical details of the equipment, and it was wonderful to tap his expertise. Thank you very much.
