The Most Powerful Computers You've Never Heard Of

The story is too good to bury 20 minutes into this video, so instead you get another Brilliant Ad.

Computer is a big word, more like a toaster i say. 😂😂😂

you can build mach 40 guns who ionize the air then you can calculate wiht an meat comuter its even faster

Okay so I guess that eventually it was for earthquakes great signing off

Would a mechanical watch be considered an analog computer? Maybe the old Bulova Spaceview watches be considered an electro-analog computer?

You have enemies? Good. That means you've stood up for something, sometime in your life.

I agree that the Norden bombsight was a failure. However, in Japan, the winds off the Pacific were too chaotic to model for iron bombs. In Germany, there is a lot of cloud. The bombardier needs to see the target clearly to be able to set up the sight. I think in clear weather the sight was helpful. However, this thing cost almost as much as the Bomb.

Wrong! There is NOT always "slop" between parts!

Actually just NAND gates

Humans can be so stupid that they are not able to eat and so smart that they can create computers that can predict waves which are precipitated by a billion catalysts. The range of thinking and problem solving skills just within a species is baffling and perplexing furthermore the play or concoction of genes , the biological code of living matter, is even more mind boggling, humans and apes are 98.8% similar in terms of DNA yet the 1.2% of genes causes all the difference in intelligence and body structure.

I think the reason that analog computer did not worked accurate was because it was being used for war and to kill people, its something God dont like.

Interesting how the worm turns. I was a mechanical engineering professor teaching Dynamic Systems Analysis from about 1980 to about 2015. During that time I included a segment on analog computers. I was often criticized by the younger more "progressive" faculty for teaching archaic obsolete" material even though many advanced systems in aircraft such as the F-16 were utilizing hybrid computers which were a combination up digital and analog computers. Furthermore, digital computer simulation programs such as Simulink, in conjunction with Matlab use essentially the same diagram approach to programming as did the analog computer approach. In my opinion, while learning about analog computers and how they generated solutions to complex problems, the students developed a greater appreciation of the actual physical nature of the systems that they were studying.

Damn it must be really hard for them back then to do all these maths without help from Stack Overflow and chatgpt

A pitfall of analog computers is that they are difficult to miniaturize. One of the reasons is the existence of parasitic devices, which requires a so-called "parasitic extraction". Asianometry recently posted a video about it.

Analog can be easy. In industry we used to 3-15 PSI pressure signals to run our controllers and sensors. Now we us 4-20 mA. It's a really easy signal to deal with and it extremely noisy environments you just use differential ammplifiers to send the signals down twisted pairs and you get a pretty darn clean signal on the other side.

Processors have small enough transistors that they could probably run the cricuits in terms of 4-20 uA, 4-20 nA or even 4-20 pA. It deosn't really matter. As long as you can manufacture a consitstent precision resistor then you just pick the current flow you want to send and conservation of charge takes care of the rest.

Worked with them in the 60s

As an Electronic Engineer who developed analog control systems in the 1970’s based on op-amps, I’m massively impressed by the mechanical analog computers of WW2. They required real genius.

This guy has to be trolling with how many things he says wrong...

Watching this while listening to "Rainy Jazz Cafe - Slow Jazz ..." music in the background is mint. Makes this so much more enjoyable!!!

Why do people say BC...?? Are you telling me the people who made this, did so before Jesus Christ? Won't that be a lie?

Thanks!

Right before you mentioned Fourier, I was thinking "Couldn't you use a Fourier series?". God I miss math classes.

@veritasium hey man, very interesting! Normally it's annoying being summoned by someone uttering the word "Stylus" one too many times but this was worth it. Don't mind the impending lolcow apocalypse merge, it's upon us and don't mind the Bedbugs either please.

You forgot the distance from the equator. Far and away the biggest determining factor of the size of a tide both high and low.

Digital computers have, in my opinion, resulted in a lot of todays "well it looked good on paper" problems.

What kind of computer human brain is and microbes r (gene RNA DNA nuclei process itself to absorb energy and multiply into tissues or animal what DNA encoded as)

I'm amazed by your videos. Sadly I'm just not smart enough to grasp even half of it

Digital computers are just blunt tipped analog computers.

Neat

This is all just kind of blowing my mind really. It is SO easy to fall into the trap of thinking that people a hundred or two hundred years ago were less "smart" than we are today. These mechanisms were nothing short of genius.

mechanical or digital, i thought of them as the same just more advanced digital mechanics... whatever' there is always so much more to learn about...

The problem with your dichotomy is that there are some devices that are both digital and analog, and I don't mean that they're hybrids. If a quantity is represented by an analogous physical quantity, but the values are constrained to a limited set, then it's both analog and digital. For instance, there are calculators that work like the one shown by the amount a wheel is turned, but detents keep those values from varying continuously. A TV tuner wherein you turn a knob to certain channels with detents is such a device that's both analog and digital.

I play my guitar through an analogue valve (tube) computer. It does complex signal manipulation in the time domain. These can be set up using control knobs. I call it an amplifier. I went to college in the '70's. Slide rules, and mechanical calculators were still used, electronic calculators were just becoming affordable. Some labs covered setting up second order differential equations using op-amp circuit blocks to simulate whatever mechanical (usually) system under consideration. Such use was touted as the reason op-amps came into existence.

Wow

Omg. A slide rule? Computer? I'm trying to learn how 0's and 1's give me a whole a** o.s.

Is analogue better because it can’t be disrupted by outside interference? Possibly

If we only knew about all the other complex mechanisms from that time or earlier than the antikythera device. The Norden bombsight didnt work because the rotation of the earth isnt there...the earth is flat..lol

Awesome

🤨🤨🤨...
🤦🏻‍♂️🤦🏻‍♂️🤦🏻‍♂️...
No, what? The artifact from the beginning of the video IS NOT/ISN'T/AIN'T OR NEVER WILL BE to supposedly "follow the constellations" . Is that a joke? 😂😂😂

Frequency. Analog can be used to capture Frequency with minimal power. Can change everything we know to be rewritten

Fascinating and mind-blowing, they are almost steampunk/scifi!

why not mentionning Alain Turing ???

One of the more exact ways to say this is it would not be a computer it would just be called and analog and be part of a digital computer

Really cool!

In the part wbout the dive bombers he should have mentioned the ju-87’s automatic pullup feature. in case the pilot was knocked out, it could pull up automatically using a computer.

Almost 2 years later (Nov 2023) and about 10 million views -- but the discount link for Brilliant still works! Fascinating topic, off to view part 2...

Why is this recommended to me just after I was listening to daft punk and watching epilogue? 🤨
