So maybe you can help me because I am making the Spanish subtitles to upload this video in English (Closed caption) and Spanish subtitles, because in this video, besides your loved grandfather, there is an Argentine scientist, Ramon Alonso, that appears in this video, and I want to pay tribute to him, and to who made possible to make this trip to the moon possible. I am in trouble with a dialog that Mr. Jack Poundstone says in the minute 23:10 to 23:14. I write down here what I have heard: "and that, in turn, causes the core (???) to move to its position." What did he say after the "core" word? Plane? Thanks a lot in advance for your help!!! Greetings to your Grandfather!!! Greetings from Argentina!!!

The actual media has never been anything but a shallow vessel for the how's and whereby's in the moon missions. The documentation and videography seems not to have been deemed important by NASA or government services to preserve all data and techniques. Films like this emanated from individual institutions supporting the missions putatively under the aegis of NASA. At one time army, navy and air force had film teaching bodies but for the moon landings that level of detailed instruction and information was evidently left in the air. Frustrating later generations who cant know now thanks to destroyed files, film, and dying scientists. Fueling the delusions of idiots who believe it was never done.

[@marcinna8553]

It is difficult to make generalizations about different times; especially since our understanding of those times is limited and our views often are filtered through our views of today's society. But I will say that there are wonderfully knowledgeable introductions to a whole host of scientific subjects here on KZbin. Some are amateurish, some not very good, but there is a very solid niche of high-quality, knowledgeable and articulate introductions, discussions, interviews, etc. that are as good or better than this film. Which by the way I also thought was great.

Wow. As someone who was born 3 years after this, in 1968, and now a 55 y/o electrical and software engineer designing autonomous vehicle software, this is just mind blowing. Watching them make those memory cores when I have 256 gigabyte micro sd card in my hand is just tripping me out. He said one holds 65k bytes of information. He means BITS!! More like 8k bytes. I feel really old right now but also happy to have lived through this amazing computing revolution. 256 Gb / 8 kb = 256E9 / 8000 = 32,000,000 Which means, I have 32 million times the memory as one of those cores in an object the size of a thumbnail, in my hand, that cost 20 bucks delivered in 2 days from Amazon. All in just 58 years. Unreal.

The technological development in the 20th century was indeed astonishing. I am 45 y/o now. Had I been born on the day the Wright brothers started the worlds first motor flight in Kitty Hawk, I would have watched the Japanese tear down the century old idea of the battleship as king of the seas at Pearl Harbor at my 40th birthday and could watch Chuck Yeager tear down the sound barrier today. I will see the Soviets have a man in space when I will be two years older than you are now and only eight years later, I will have retired a year or two before, I will hear „A small step for a man, a giant leap for mankind“ Maybe I will take the Concord to celebrate my 75th birthday in NYC. Impressive development, isn‘t it?

yes but listen to what he says about how the memory is constructed @13:03 he completely dodges the question in regards to erasable memory and his explanation of fixed memory is very odd... instructions woven into the pattern of the sewing around magnetic cores.

@@nagualdesign As valid as the opinion is, and as free as anyone is to express it, it's still not helpful to stand around a trainwreck just saying how gross all the blood is. If that's an opinion that one wants to have, entitled and unempathetic and too good to google anything or think about possible solutions, perhaps it would be better to have it further away from the crash, and stop distracting the first responders (many of whom aren't doctors or lawyers or astronauts either)?

[@nagualdesign]

@@alakani That quite an analogy. Not sure if I really understand. So you're saying that comparing today's TV documentaries to the one shown in the video is like witnessing a train wreck and being too up yourself to start Googling "how to respond to a train wreck"?

[@alakani]

@@nagualdesign It's just a metaphor. Humans are far from perfect, especially in a contemporary society that's evolving faster than our biology can keep up. We're subject to a wide range of logical fallacies that stem from cognitive dissonance and other cognitive biases. Personally, I have to read a list of logical fallacies and cognitive biases almost every day, and put in an active effort to try to catch myself as much as possible, and I'm still terrible at it. But it's necessary in order to have a deep conversation, which isn't something that strangers usually even attempt (due in part to Dunbar's number). So I appreciate you taking the time, but the straw man arguments are making it more difficult. Hopefully it goes without saying, if you've noticed anything I could be doing better, please let me know. But yes, in general, I think people who complain should also try to do something, ideally something evidence based, or at least say their ideas for solutions at the same time as complaining. And ideally have some empathy for the world of people who are getting even more screwed than Jon here by the decreasing availability of quality educational content. Maybe it would be better to think of it like 'wow I feel really bad that a whole generation of kids might grow up without some of the opportunities that I had, what can I do to help?'

In part it is like that because today's smartwatch is 1000x more complicated than the whole AGC was. We use more and more "things" that were made using CAD techniques, and human just couldn't done it without computers. Same is with algorithms - let's take the the neural networks - we know how they are constructed, understand principles of their work, but never know how and why they returned a particular decision. So quite often it is our ignorance, but also - our world is just too sophisticated for us, so majority of us quit trying to understand it.

[@larryrouse6322]

When I was in the Navy I worked on the SLQ-32 which was an electronic warfare system also made by Raytheon, and a lot of this same technology was still in use. In 1993 I was assigned to the Program Office that oversaw the SLQ-32 project, and I went to the factory in Goleta, CA where they were using that same wire wrap machine to manufacture motherboards for SLQ-32 units, although the paper tape reader had been replaced with a magnetic tape unit. The SLQ-32 had four 128KB magnetic core memory modules, each module consisted of three cards, so it took 12 cards to provide 512K of memory, and this was in the 1980s. It was enough to hold an emitter library that contained 256 emitters in a fixed library and 128 emitters that could be entered by the operator. The magnetic core memory was just being replaced with more modern RAM modules in the late 1980s. The Navy clung to magnetic core for so long because it was non-volatile and easier to EMP harden. The Apollo computer and the ROLM1606 of the SLQ-32 could get by with these tiny amounts of memory and processing power because all they really did was crunch numbers. There were no fancy displays that use up most of the processing power in a modern computer. On Apollo, most of the computational heavy lifting was done on the ground and transmitted up to the computer. All the onboard system had to do was perform some simple calculations and fire the thrusters at specific times for specific durations, or as shown in the video, slew a telescope. The SLQ-32 just had to compare the numbers it got from the receivers to what was in memory and display a symbol. Prior to the space program, most of the designers' experience with portable computers was with mechanical systems that were used for gun laying or navigation, and you can see some of that kind of thinking in the design of the Apollo computer. The rope memory, in which the software had to be woven into the modules is really a mechanical solution to a digital problem, and the machine that indexes the modules to the proper position when a switch is tripped by the needle being inserted through a hole is really a mechanical computer. It shows the almost limitless ingenuity that goes into solving these problems.

[@Godscountry2732]

Great information Larry....Also ,the MIT.Raytheon built flight computer was 10 years ahead of anything as yet developed.It was actually like a Apple II of 1977 heritage It was more then capable of flying the spacecraft.While a Iphone could run the flight program code in a app,.It would likely crash and require shielding to protect it from radiation interference.I'm betting the gold box gets me to the Moon and back 10 times out of 10 ,

[@zarion1181]

I like this Split-flap display. And this wire-memory is pretty baffling. It is amazing you still use this technology in the SLQ-32 project. Amazing stuff!

[@larryrouse6322]

I do want to be clear that the SLQ-32 used magnetic core memory as RAM. The actual software was on magnetic tape cartridges. The wire rope memory that they show being made for the Apollo computer was based on the same concept except there were no write wires installed. the magnetic cores were polarized and installed then the wire was woven through them as shown. One core installed backward and the whole module was bad. They were roughly analogous to a late '80s vintage game console cartridge in that to change the program you had to swap one module for another.

[@larryrouse6322]

Well, the SLQ-32 program was initiated in 1975, so it wasn't that far separated from the Apollo program. The mag core memory was phased out of the fleet systems by 1995.

As an electronic engineer, one of whose high school lecturers worked at Bletchley Park, and 80s computer geek (go 6502!) the whole AGC story simply astonishes me. Take nothing away from the challenges and efforts elsewhere in the program but this was off the scale and breaking the boundaries of what they even thought might be possible. I worked with ferrite-core memories in warship fire control systems in the 90s. They were reliable and robust but antiquated (though for ‘antiquated’ read ‘proven’) and were orders of magnitude smaller than those of Apollo. I truly believe that the AGC was the most ‘giant leap’ of the whole Apollo program.

Nuclear-strike proof, simple, but fully functional. To have that type of technology utilized to its max in order to fit into a rather tiny box and navigate through space is a real achievement.

The link below is the first in a series. kzbin.info/www/bejne/aHy2kpt3pLR_mrc If you enjoy the technology of yesterday, you will enjoy this series as well.

Man, he does look like Sheldon. But he would probably be Sheldon's grandpa.

Absolutely amazing how much of the manufacturing process is done by hand. I remember doing wire wrapped prototype boards by hand.
