    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. ( )

      -Matter didn’t create anti matter
      -Anti matter didn’t create matter
      (Both of them were present at the time of big bang)
      -Both of them didn’t create themselves.
      -Both of them came from an unimaginable source, that unimaginable source created matter and antimatter (everything) thats why it is known as “the creator” of everything.
      —and that unimaginable creator created all prophets (approx 124,000 from Prophet Adam to Prophet Mohammad pbuh) who introduced God/Allah (an unimaginable creator) as well as they came to us with the complete and beautiful guidance of mankind from the creator of mankind.
      Thank u :)

                          My 5 yr old boy and I love your videos. In fact your video on laminar flow impressed him so much that when he visits a fountain of any sort that is all he looks for. Can you do a video explaining Prince Rupert's drops. Thanks.

                            Typical space videos by nasa, real life money loss, aka launching rockets into the sea with no humans, then cgi all the way till they end, last but not least recycle rocket from sea and repeat.

                                  so I found a cool science anomaly that I haven't seen before and I searched it up and can't find it or an explanation. if you take a 2 by 4 block of aluminum and you put it on its side, so the short side is facing up. then if you slightly slant the block and roll a cylinder magnet down at a slight angle it will seem to bounce off the side of the wall as if there is an invisible barrier.

                                    At 2:00, you are describing "core" memory, which was the type of memory used in most computers up to around 1975-1980, when semiconductor memory first entered the scene. I worked on an IBM 1620, a 1401 and others, including a minicomputer made by a company called Microdata, which all used core memory. (I'm 72.)

                                    I still have three 8K memory boards from that Microdata computer. (Failure of this type of memory was common, so I decided to save boards when they were replaced.) I remember they were priced at $3,500 each back then, or around 5 cents/bit. At that rate, 16GB of RAM (128 billion bits), now commonplace in PC's, would cost 6.4 billion dollars (without accounting for inflation)! That's over double the entire Apollo program budget. (Good thing they didn't need 16GB.)

                                    Just as shown in this video, I can see the little cores arranged on the grid of wires. I was amazed back then, and I still find it impressive today. Here's an interesting fact about core memory: In order to read a bit, the computer would actually write a zero at that location. A sense wire running through all the bits on that plane would detect a pulse if that location originally contained a 1 because reversing the magnetic direction would induce that electric pulse. A second cycle was then required to restore the bit back to a 1 (or leave it as 0 if no pulse was detected). This was known as "destructive" read, requiring two machine cycles. One cycle on the Microdata was one microsecond (1 MHz). A modern CPU running at 4GHz is 4,000 times faster. But one cool thing: if the computer lost power, core memory was preserved! It wasn't 100% reliable, but often, when the computer was powered back on after a power failure, it could continue running where it left off!

                                    Anyway, I am wondering what to do with these memory boards. Right now, they're just gathering dust in my closet. Any ideas?

                                                  This video is supposed to be about a modern computer nerd and a 60s computer scientist interacting with each other, but what I'm more interested in is Linus being on the same screen as someone with a native Alabama accent lol

                                                    Would the MOS 6502 Processsor of Comodore64 be enough to steer such a rocket?

                                                        Absolutely INCREDIBLE!!! I remember getting up early in the morning in the 1960's to watch a rocket launch on TV and it was an amazing feat back in the day. To see this "computer" that made that happy is mind blowing. These guys were amazing and it worked. Thanks for this very cool video.

Could you "blind" a speed camera if you had license plate lights that were like infrared spotlights? And if so, is it possible for a light to put out both visible and infrared light simultaneously?
