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. ( )

Hey I have a question that you can help me figure out. Why is it when your driving down the road you look out in front of you the road is black but in the mirrors the road is grey. It also work backwards too.

@Unknown Infamous
"Enjoy your new reality" is a common close for me. It's not necessarily a put down, rather another way to say, "wake up".
The truth of our reality is resisted with combative disregard and insult. It's easy to get lost in the war against information. With space being abundantly propagated on tv, I am irritated almost all day. So yes! It is personal!

I know this is way off topic buuuutttt. Have you thought about letting a snowmobiler ride your backwards bike? We counter steer all the time! My mind went laminar when I thought of it! :)

So where is the video of these women weaving these things? I would love to see that.

5:09 "They're comparing the output, making sure they get the same answer." What would cause them to get different answers?

(By the way, how big was a word on those computers?)

Destin, PLEASE have that wart burned off of your lower lip. I find it very distracting.

Thank you for this video. I've always wondered how someone like Linus would react to the Apollo's woven computer.

SmarterEveryDay Is that Reepicheep at the end of the video!? Also, great verse

Hey, Destin! My family runs an orphanage in Asia; we're in America every three or four years. My Mom lives in Dayton, TN, and after watching this my sons (ages 9 and 13) want us to add a trip to Huntsville to see the rockets. We use your channel as part of our home schooling, so thank you for that.

If we're on the road from Dallas going to TN, can you recommend any other educational stops in the area?

Thank you!

As a former IBM engineer who worked on these core memories in the UK I was told that the ladies who wove the doughnut memories as we called them were Taiwanese Fisher women who had the skills of making their very fine fishing nets.

They don't make us RF engineers anymore now they make card swappers

hi ..... I have question in my mind, if we rotate a coil in magnetic field it induces current or vice versa, so can we charge a mobile phones having wireless charging by rotating a magnet near to the coil. Can u make a video on this experiment.

Hey, Smarter Every Day! I was wondering how exactly a water softener works. I know what hard and soft water is and I know that you dump salt into the softener every month or so, but what is going on here!?!? Thanks!

The more one learns about the dawn of computers, the more in awe one is of the men who created them.

I lost it when the camera panned to the diagram to show that depending on how the rings were magnetized it represented on and off for the bit. I just ***king lost it.

I would like to know how equations are created to solve a problem and how each number and value is come up with mainly asking for new studies and problems that are unknown at this time how would you begin to research and test what you come up with and know that the answer to your problem is correct if you are not able to physically test it

Boys and Girls it doesn't matter how you thought you were supposed to pronounce "module". THAT is how you pronounce "module".

The phrase: "Standing on the shoulders of giants" comes to mind. Huge respect for the "cowboys" of the computer era. Without them, we'd still be using slide-rules.

You should make a replica, bring it back, and smash it in front of him. THEN insist it was his fault. Hilarious

I'm sorry for that guy with the earrings. He's actually out of place. He hold the memory module for about 10 or more minutes. He could have drop it. Except for Luke Talley, you merit a thumbs down guys.

That was absolutely amazing. Love this first hand knowledge. What an honour that must have been! Brilliant. Thanks so much for sharing.
