    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. ( )

              A thing to note here is that the "modern" computer guy is an information technologist. He's not a computer engineer. I don't think he really has an appreciation for how those old computers (or new ones) work.

                                I’m kinda surprised you said;
                                “It’s almost like Luke could run around both of us”

                                Ya think? He is an actual rocket scientist. I would hope he could.

                                      Have you heard about a man named Sandy Kidd? He invented a gyroscope anti gravity machine many years ago in his garage. Trust me, you will be smarter today after you research him and watch both of 2 videos about him. Fascinating stuff. I’m unable to post a link because my phone is not too smart today but I strongly recommend you look into the guy. Thank you! Look for, Sandy Kidd inventor of ant gravity machine.

                                        Also, in part 2 of the videos he, Sandy Kidd actually participated in the comments and he has a lot to say.

                                            Please tell me this: How did ESA steer that rocket 300 MILLION miles to intercept a moving asteroid and drop a lander on it? 300 Million miles...of space vacuum. Except, there are gravity fields EVERYWHERE out there and over the course of 300 million miles, (It is 93 Million miles to the SUN.) you'd think some unpredictable deviations might occur. BUT WAIT. What about DARK MATTER? We are told that it is everywhere, distributed in ways no one can guess, but, it has MASS. Now how can you navigate thru a random field of dark matter? Were they relying galactic star
