    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. ( )

    I see passion here. Passion is important. This is what I tell some dumbass doctors or some people.. if you can't explain something it doesn't mean a one has not graduaded proper university but it means you don't understand it and you don't have passion anymore.

    Luke Talley is so intelligent and knowledgeable and clearly it was people like him who put a man on the moon. They seem irreplaceable today. I’m of his generation but my mind is not up to understanding 1/100 of what he’s saying and I’m no dope. I’m humbled.

    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.

    To get all the way to the moon many of the the calculations were made by NASA's "Human Computer" Katherine Johnson, an African-American Lady who also calculated the trajectory of Alan Shepard's Murcury mission, the first American in space. Computers at that time were merely "clocks" that timed events.

    I have new respect for the whole space vehicle. I have always wondered why space flight costs so much. I remember news reports that NASA needed so much money for continued exploration. 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.

    Greetings from Australia! This is an absolutely fascinating video. 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.
