You guys love technology, but can you guys honestly explain how the technology you love actually works?
>>
sorry to be that guy but I hate technology
>>
Some of it. I could probably give an explanation for all of the things in your image, and a demonstration of the principle for maybe half of them.
For a computer, I think I could explain some of the principles, but there's a lot of layers of abstraction that make a modern computer work, and I'm sure I don't understand all of them. Interesting question about abstractions.
>>
Discs are actually incredibly simple, so simple that's it's shocking that it took that long for people to figure it out.
What's more shocking is that just a bunch of grooves & pits on a malleable piece of material can make sound.

I know more than I am comfortable with to be honest.
Getting down to the physics removes a lot of the magic from life, but enables you to wield magic too.

Yes, to a significant but not total degree. My knowledge of how circuits truly work at the electromagnetism level is very limited unfortunately. I'm vaguely aware of EM fields and charge and such but I don't think I'd be able to convince someone who had never encountered electricity that I knew what I was talking about.
If we get past that layer then I can start talking intelligently about circuits, logic gates, processors (at least basic ideas like registers and memory and fetch-decode-execute), assembly, operating systems, applications, networking, security.

I'm not a car guy but I could probably fudge together a description of how an ICE or motor works and something about transmission. I could describe sound as rapid variations in air pressure, and how this can be used to make microphones and vinyl records. I don't know much about optics except as it relates to my eyesight/glasses (researched some optometry stuff).

This reminds me of the concept of ancient accidental microphones, like maybe sounds were unknowingly recorded thousands of years ago while spinning a clay pot and maybe we could recover it.

If he did know how they worked, they would be unable to comprehend any explanation anyways

But to answer the question, no. I don't. I mean I have some understanding of how HDDs work for example, but I couldn't tell you the HOW of the how.

Yes. I studied computer science on my own while working as a programmer professionally. So I know how computers work from the hardware on up. It is interesting to think how many "coders" probably have no idea how RAM works but they don't need to. But it is extremely enriching to be able to visualize how the computer works and ultimately manifests your code into reality. From the logic circuitry all the way to the compiler and the pixels in the display. It's an incredible thing, the layers of abstraction.

there certainly exist examples of objects containing perturbations caused by the sounds that were happening at the time is was set, but whether they're recognisable/recoverable and indeed of any useful fidelity or length to be of any use or interest whatsoever is another story
even /intentional/ recordings made before people had a way to play them back are pretty garbage, like you can barely make out what is being sung here, and people originally thought it was a woman's voice before finding out he had included a tuning fork sound for pitch reference, which is a pretty clever solution for something that couldn't be played back at the time

For a computer I used everything from Python to x86 assembly to simple verilog. For hands on hardware I soldered stuff like split keyboards.
I could tell them about logic gates but they wouldn't be able to understand the explanation. Do you expect me to create actual chips from sand?
If they have magnets I could produce electricity after some fiddling around. If I had access to medieval tech, I could probably build a steam engine.

This one's the easiest, the romans discovered it on accident by spinning metal. Any magnetic field rotating creates a current. It took almost 1500 years later for Gauss and Faraday to put together the first theory on how that was working, and why.

It's simple enough to explain how they work, but demonstrating them is a bit harder, and making them to a useful degree is harder still.
You can probably explain how an internal combustion engine works, but could you demonstrate the concept using the materials and infrastructure they have? Could you then build a useful machine that makes use of one? A car requires a lot of different pre-existing things to be useful (not least, roads) but even a simpler rotational device powered by an internal combustion engine, like a mill, is not simple to build when you don't even have metalworking or chemical manufacturing.
>>
>>108702728
Easy to make electricity, but now what will you use it for? Charging a phone? Lighting a lightbulb? You don't have those things.
Maybe you know how to make a filament, and there will be glassblowers you can call on, but do you know how to get inert gas in the bulb?
Nearly everything we use is built on layers and layers of complex skills.
>>
>>108703496
yea, explaining a bunch of principles is one thing, actually making them totally from scratch is another
https://youtu.be/R3Qn98bE880
>>
>>108703484
>but could you demonstrate the concept using the materials and infrastructure they have?
First thing first. Show then how to do pulley systems, how to do wrought iron, how to produce steel. Then you gotta bootstrap precision, produce a surface plate, lathe, micrometer, and just make simple steam engine.
>A car requires a lot of different pre-existing things to be useful (not least, roads) but even a simpler rotational device powered by an internal combustion engine, like a mill, is not simple to build when you don't even have metalworking or chemical manufacturing.
Just start with steam machines. These are much simpler. It will easily figure out how to make a steam engine while you will be waiting for all the steel to come.

There is many more low hanging fruits to start with first though. Engines can come later.

Yes, enough.
But if I were to build an engine I'd, at least at first, only be a me to make a two-stroke engine.
I'd not be able to make transistors but I'd be able to make large analogues.
>>
>>108703692
>I'd not be able to make transistors but I'd be able to make large analogues.
i know some of what is required to make a vacuum tube (as in the classical transistor equivalent with the anode/cathode/grid), but only really in passing and not much in the way of specific manufacturing details.
if i was to actually have anything made in ye olde times, i think i would focus on trying to convince some smart fellows to actually flesh out any missing information, like just having an idea, especially one you already know works, is by itself a great advantage, even if you don't have all the information required to execute it from the start. at the end of the day even if you had idk a copy of wikipedia on a solar-powered handheld most things you still just can't do on your own
>>
>>108703588
OK. Do you know how to make steel? Most primitive people don't even know how to make iron. There are accounts of them destroying boats as soon as they land to get at the iron nails used to hold them together.
You probably know steel's iron plus carbon. Where are you getting your iron from? How are you getting to the high temperatures required to make steel? Know how to make coke? Know what form of carbon you need and how much?
On and on and on like this. Every single step is made up of all these other steps which are themselves, not insignificant.
You could probably get to a demonstration steam engine. The Greeks knew about the principle of steam power and made a primitive steam "engine". Can you make it powerful enough to actually do something useful? Probably not. You aren't an expert in steam power, so it's probably going to be pretty difficult for you to figure out what makes a steam engine work well rather than simply work.
>>108703585
I didn't watch your video but yeah, I agree with your post. The toaster mentioned in the video title is probably one of the simpler things to make in theory and I still think it would be incredibly difficult if you were in a primitive society, even if you knew about toasters in extreme detail.
>>
>>108703964
>I didn't watch your video
it's probably about what you expect, just a brief humorous talk where he demonstrates just how hard it is to make simple items. he does produce a bit of iron, copper, mines a bit of mica, and makes something like plastic to produce something resembling a caveman's toaster. it covers just enough to make the viewer realise that a ~6 dollar toaster truly does require a civilization to produce.
also note that while he does procure the raw materials from mines, he processes them with modern tools, so even this wasn't entirely from scratch
>Do you know how to make steel?
also lol, not him but i actually just recently went over a video on steel, the video caught my eye since i wasn't really sure what the difference between iron and steel actually was. turns out it's just iron and carbon, but just saying that makes it sound easy. it's not easy.
>>
>>108704035
>>108703964
-- well i say brief talk but only the talk was brief, he spend most of a year on it, between research, procurement and production. even the simplest items today are technical marvels only a few hundred years ago. it being a toaster is obviously a nod to Hitchhikers' Guide the the Galaxy, but it's the perfect example, the most dead-simple plastic electrical product many people use every day, which costs nothing to buy. the kind of thing people today can't imagine a context where such an object is considered impossibly complex.

I'm thinking you might want to skip combustion engines entirely and go straight for electrified everything. Agricultural tech would be the priority, to free up hands. So an electric tractor, combine harvester, and synthetic fertilizers. Then the rest of the electricity tech tree, namely radio, telephone, computers. Refrigeration is of course quite important. It would be nice to skip fossil fuels entirely but I'm not sure how feasible it would be. They would at least be partially needed for rubber tires and such.

>>108704104
Hold up, is the goal to produce a literal modern toaster that you buy at the store or anything that toasts bread using electricity? As in, would one of those early toasters count?
>>
>>108704104
>people today can't imagine a context where such an object is considered impossibly complex.
or at the very least; needlessly complex.
explain this to a civilisation that doesn't know electricity and they'd surely tell you that toasting bread over a fire makes more sense. even if had a toaster you still need an environment where electricity is commonplace for it to make any sense
>>108704180
the goal is to make something similar in design to a modern toaster as well, of course there is many ways to toast bread. like the plastic cover is technically superfluous to the goal if the goal was just to toast bread. but no, the goal was to /make a toaster/, namely something that tried to emulate a modern toaster

Maybe drive an electric motor, or charge a battery to drive an electric motor, which can be used for various things. This guy collected and smelted the ores to make a battery on his own:

https://www.youtube.com/watch?v=wGgU-r9GBXE

I dunno if those would be suitable for cars though. Apparently telegraphs used that type of battery. Electric cars came before ICE cars so, probably would want to read up on the battery chemistries they used.

It's all kinda dependent on what level of civilization you're working with too.

also since i'm posting this much text, i may as well clarify the image wasn't /intended/ as a test image nor was it intended to be known this long, it was just a Playboy magazine photo, the face/bust of which was used in the '70s as a means of testing an early digital image scanning drum, and the rest is history.

>>108703964
>Where are you getting your iron from?
Probably look for some orangish or black magnetic rocks. No i don't know how to make a magnet without iron and electricity, but some iron heavy rocks can be naturally magnetized AFAIK.

>How are you getting to the high temperatures required to make steel?
A lot of charcoal or coke, bellows and a bloomery I guess. Dunno how to make one that can take such temperature, but I guess some ceramic brick maybe.

>Know how to make coke?
Heat up coal without oxygen?

>Know what form of carbon you need and how much?
Dunno about carbon, the cleaner the better I guess. About 1-4% IIRC.

>Can you make it powerful enough to actually do something useful?
With enough time, probably. But I am not claiming these things are trivial. I'm just answering your quiz. My initial claim was that an educated person should be able to explain how all the things in OP image work, not how to manufacture them from scratch.

>>108704147

Top left: idk what that is

Car: a fire causes gas to push a piston (metal block fit snug in a metal tube) that pushes a rod that pushes a set of gears that pushes wheels. Turn off the fire to bring the piston back to restart

Music disk: sound is created by air pressure changes. The different groves on the disk are matched to different levels of sound (pitch, volume etc). A needle hits all these groves over time and produces those sounds. Idk exactly.

Telescope: i know you can focus light to a point but idk. Should look this up

Light: when electrons are running through a wire, they run through the big clear wire (copper) into a tiny messy wire (tungsten) which gets heated up when the electrons bump into the wire (not exactly sure why, is it similar to heat causing friction?) which causes light the same way as a hot rock does

Bottom left: idk same as music disk?
>>

Oh its a phone. Use pulses of electrons through copper to produce signal, then you need a device that converts signal to sound. Idk, pretty complicated. Also how do you direct the signal to a specific phone.
