Welcome to our participatory science community. Join us in looking at the world like a robot would, finding where the numbers in word problems come from, electrifying the floor, stacking our atoms end-to-end to try to reach the moon, measuring calories with fire, constructing high tech bat houses, exploring the world's largest Vande Graaff, talk with other scientists and engineers, meet snakes, and put the A in steam with Art Assignment videos.
This channel is about having fun with science. We will do hands-on projects. Science is not just a spectator sport. Our goal is Accessible Science Joy.

Just agreeing with everyone else. This video is amazing. I even read Elden Hall's book, and I'm learning more about how the computer actually worked and how the astronauts interacted with it. Thanks for the hard work!
I was doimed once in a competition by the high speed and low torque of my robot if the an off the shelf mechanical product that simply controles torque
that lunar landing would have to be one of the greatest human achievement's, considering the technology they had at there disposal at the time, they had to invent every piece bit by bit as they went along and they pulled it off miraculously ???
Its a wonder it even worked. I dont know who the AGC Software Programmers were, but they are the unsung heroes of Apollo 11. Making the first computers and knowing even one realtime bug would be a disaster.
You gave me the idea to use quadrature encoder to attach the magnet, so instead of offsetting the hall sensor I offset the magnets in the wheel. I wonder if this setup would work and the signal is not picked also by the other inline sensor. Also is quite tricky to find the correct alignment
Pretty good summary, with accurate details, deep insight in many fields while remaining very accessible. Thanks you. You got a new sub, and you deserve way more!
It's astonishing how some seems to think that we're going to space on the back of microprocessors. It may surprise you, but to go to space, one needs *a rocket* not a computer.
Wonderful video & great job!! But your opening statement is a bit false; this computer was built to fly the rocket as well be robust enough to handle the vibration of launch & control the spacecraft, amongst other things. You explain this later so it's weird you open w/that.
with transmission delays,how could real time data be any use??they would have hit the ground hard with those delays.another naza fairy tale and cheap effects.if you don't look,you can't see.maddog.off grid.West cork
during most of the mission, there was lots of time to correct errors. The time-critical parts of the mission were done by the AGC on board the LM, so there was no delay.
The computer was onboard the Spacecraft. If needed, the Astronauts (who were all mostly test pilots) would manually take control to fly the LM to land. What's naza fairy tale?
thank you for sharing knowlge. i am try to make a big servo using 775 DC moter but using potentiometer and other servo componts. so can you please guide me, please.
So you feel important enough for such a conspiracy? If you asked to prove it, you'll just send a link to American Moon, this pathetic documentary that has been 100% debunked?
No, son. It is not a fraud. I get that you don't feel like a man unless you're having to make less of others more capable than you but at least get an education, such as in an engineering field.
@@physicalivan : No, son. That's just your wishful thinking. First off, learn how to spell and if you're going to use the excuse that English isn't your native language then write in your own language. Have some pride in how and what you write. Not doing so just shows you're not sincere. I understand it makes you feel less telling you that I'm an engineer but that's your personal mental issue, nothing more. But sure, keep closing your eyes, covering your ears and shouting to yourself, "la la la la la..." to drown out reality so that you can live in your bubble world.
I don't know why this always bugs me so much, but when people talk about going to the moon and saying that the craft needs to leave the Earth's orbit, they are mistaken. At no point on any lunar mission did any craft leave the orbit of Earth. Think about it. The MOON is in Earth orbit. You don't LEAVE Earth orbit to go to the moon; you're just put on a highly elliptical orbit until you make another burn to orbit the moon. You're still orbiting the Earth though. You and your orbit around the moon are collectively in orbit around the Earth. You never leave Earth's orbit.
@@colinsouthern This is incorrect. The TLI burn from Earth that sent them to the moon put them on a trajectory known as "free return" - - meaning if they did nothing else, they would circle around the backside of the moon and be slung around and return to Earth. At some point on the way to the moon, once various systems checks were performed, they altered this trajectory that would allow them to be captured by the moon. At no point in time where they ANYWHERE NEAR a trajectory that would escape the Earth's gravitational influence. As for the ISS, the whole "centripetal force" explanation is a gross overcomplication. It doesn't matter how strong the gravitational field you are in is. If you are in free fall, you will be/feel weightless. Many people conflate this with the absence of gravity - which it most definitely is not. The notion that you leave Earth's orbit simply because you are experiencing weightlessness is erroneous logic. You can ride a free-fall type roller coaster right here on the surface of the Earth and experience literally the same state as a spacecraft in space. It's the same weightlessness, and it is not caused by any alterations in the gravitational field, but rather the result of being in free fall WITHIN that gravitational field - - which was the case for the vast majority of the trip to and from the moon. They are simply coasting. A free fall ride here on Earth just lasts a fraction of a second as opposed to the days Apollo astronauts experience en route to and from the moon / and in orbit.
@colinsouthern no. They far surpassed escape velocity. They aren't even orbiting the sun. They have reached escape velocity of the entire solar system. Challenge me all you want. I know what I'm talking about.
@@colinsouthern No. STEP ONE : Launch STEP TWO : Get into Earth orbit STEP THREE : Translunar Injection - - AKA, send them to the moon. THIS trajectory was a free return. STEP FOUR : Midcourse (between Earth and moon - AFTER systems checks, etc.) taken off of a free return to a trajectory that would allow them to get into lunar orbit STEP FIVE : Get into lunar orbit. For example - the Apollo 13 explosion occurred during a point in the mission that they had already performed the maneuver that would take them OFF the free-return trajectory and on one that would allow them to perform a lunar insertion burn once arriving. They actually had to perform another burn to put the BACK onto a free-return trajectory and return. I feel like none of this is going to make sense to you.
Can please help me, How to use an optical rotary encoder to stop the motor when it rotates a certain amount, I’m building a cablecam, the cable cam should stop automatically when the cable cam reaches a certain distance
