    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. ( )

      One like is just not enough -- you are doing a public service for the future -- this kind of memoir is rarely recorded, and needs to be encouraged!

                  @Smarter Every Day 2 >>> Seeing how _complex_ this system was, it is REALLY AMAZING that when Apollo 12[?] was struck by lightning after liftoff, the vehicle EVER operated correctly again. Faraday Effect or no Faraday Effect....

                                              A family friend worked at ILC Dover on the space suit glove and wrist joint. I love to hear him talk about those times and all the intense engineering that was done on just the glove and joint. These people are a wealth of knowledge about a very spectacular time in our nation's history.

                                                      Destin, I love every single one of the videos that you have on your channel, but this tops everything else, this one is pure gold. Thanks to you, Linus and specially Luke (sorry, he is the star this time, haha) for giving us this kind of knowledge about something that is truly amazing and inspire all of us who loves science in general. As a programmer myself (and a computer and general technology lover), I feel very happy to get to know who (Luke included) were responsible for the creation and/or development of computer technology (because there was a lot of smart people involved through the years). I feel that people like me kind of owes eternal gratitude to men like him.

                                                      Thanks again! To me, your channel is easily one of the 10 BEST channels on YouTube. Always good stuff here.

Linus was so respectful and just soaking in the knowledge in the first part but once it got to the cooling, something he is incredibly knowledgeable about, he started spewing questions and fully engaging and it was quite endearing

We'll be in Huntsville later this year just to see the NASA center. Can you recommend any other educational stops in or around Huntsville? Thank you!
