Fools as i carry with me all of human knowledge, right here in this fragile tiny black slab. I can tell you all once you tell me what your wifi password is.
As a side-note: You can download Wikipedia.

It's happened. He's time traveled and been cut off mid post. Also apparently lemmy doesn't handle timespace folds gracefully.
I hope this is fixed in 0.18.6
Truly we've all been affected by this bug from time to time to time to time.
Something went wrong, looks like they are stuck in a time loop.
Keeps posting the same cut off sentence.

Then you realize that, back then, the only thing they had were Xfinity hot spots.
Worst Isekai. I didn't finish it though so no I don't really know I just didn't enjoy episode 1 with my smartphone.
All you have to do is teaching intelligent people some math and tell them about experiments and that nature can be understood. The rest will follow.
Everything can be accelerated by adding the idea of the printing press.
The main challenge with inventing a working printing press would be the papermaking and level of metalworking required for the movable type.
pretty sure you can just use wood or whatever for the lettering, sure it might be kinda shit and tend to break but it should work. having to make new letter stamps every now and then is better than painstakingly writing every letter for hand.
This book Tells you how to handle this, along with everything else you need to know to rebuild all systems in society from scratch should there be some sort of time machine based accident. It’s a good read!
Let's see... electricity in a preindustrial environment. You'll get into Factorio levels of invent a tool to make a tool to make a tool...
Copper wire existed at the time, (depending on the time period) but drawing it involved a person on a swing pulling it through a hole in a metal plate. So we need a metal plate. Surely there is a town blacksmith? We will need a few plates with gradually decreasing hole diameter. Enough wire for a demonstration would be difficult and expensive, but not impossible. Could also use copper busbars instead of wire.
Now that we have conductors, we have to figure out what method of generation we want. Rather than trying to make bearings, balanced shafts, and stacks of thin metal plates all identical and radially symmetrical so we can make a generator, we should first attempt a battery. For this we can get away with stacks of two dissimilar metals in a glass or ceramic jar, bathed in some sulfuric acid. Aqua Regia was a mixture of nitric acid and sulfuric acid, but it might dissolve copper and zinc plates. Could also use lead plates, those are easier to hammer out flat. With this we could get an output around 2v per cell, put a half dozen of them together in series and one could build a simple arc lamp.
After the proof of concept demonstration, hopefully you'd interest more smiths in the project, increasing your talent pool. With some mercury and wire you could build a version of Faraday's homopolar motor.
After that I'd probably be burned at the stake.
There was a short story I read ages ago in some collection somewhere I've been dying to find. I think it was from the 60s or 70s, but a scientist brings a man from the future and the man is just a normal guy, so he can't explain anything to the scientist's satisfaction and the scientist gets more and more exasperated.
The dialogue was like:
"What is the dominant mode of transport in the future?"
"Oh, we fleem."
"Fleem? What's fleem?"
"It's a kind of garbol but with more slimp."
"Okay, never mind. How do you do it?"
"Oh, that's easy, you simply merfingle the blem and you're fleeming away!"
"WHAT IS THE BLEM?!?"
It isn't so hard really, to make electricity even in the olden days.
A dynamo is just a copper wire with a magnet spinning inside.
Making a copper wire you can accomplish by having a hole at the bottom of a kiln that drops directly into a big vat of water. Or even just drawing a line in the sand and pouring it in there.
Getting your hands on a natural magnet might pose more problems, but ultimately those are found in nature. So they should have already been dug up by someone.
Using the electricity usefully is harder. Since creating a light bulb needs access to gasses. What could we even use the electricity for?
If you can make a dynamo, you can make a motor. Now, you aren't about to create Tesla. But there's plenty of things back in the day that could benefit from being motorized.
You can create light with electricity with two carbon rods to make an arc light. It was literally the first electric light source and in widespread use for a long while, along with incandescent bulbs.
You use it to charge your phone, duh.
You spin a magnet near a loop of wire
"What's a magnet?"
Umm you go to the beach and something about certain grains will be different. Look mate, see how you boil liquid. Do that with milk until just before it boils and that's the milk now pasteurised which means it will kill the things in it that make you ill. Also boil the water before drinking it?
That's all I got. I guess sphagnum moss is good for absorbing blood/dealing with wounds?
“Get something bottle-ish, add a layer of charcoal, a layer of sand, hooray and a cheer! you just beat diahrea”
Is this a repost? Has lemmy already entered the repost phase?
I mean, could you imagine? The horror..
Watch this Jim Al-Khalili documentary for the BBC, then jump into the time machine.
Just bring an encyclopedia with you, history of human advancements and history of human equality if you want to improve equality as well
They should make a movie about this. An average guy accidentally time travels and feels embarrassed every minute
Did you skip 3rd grade (and all other) science class?
I mean, from this thread it shows people kinda remember stuff from those classes, but are missing a lot. Which is understandable, people left school and didn't use that information, it doesn't make you stupid.
But then you think, oh yeah! I remember how to make electricity, I need copper and an iron rock! So you spend all this time trying to manufacture some relatively thin copper wire, iron would probably be a little easier to find, wrap it around and then you're like.... Okay what went wrong? Annnnd you can't remember you actually needed a magnet and you gotta spin it.
Then do you remember learning how to store it? Connect it to anything useful? Maybe kinda, but extrapolate the first situation to every topic ever and that's what you'd get, half baked ideas that you don't really remember the specifics of. And the specifics really actually matter lol.
Even if you studied it, the answer boils down to "magic".
You take these magnets, and move them around these long snakes of metal (because electrons can move easily through metal) and that makes the electrons in the wires move.
Okay, why does moving around a magnet near metal make something inside it move?
Well there's something we call the "Lorentz force" which basically pushes a magnetic thing in a specific way if you move another magnetic thing around it
But why does that happen?
Magic
If you went back in time and tried this, most civilizations would probably burn you at the stake
Something to do with turbines.
Water wheels seem to spin a turbine. Maybe it generated current or something. Similar with windmills? Gyroscope or something.
Solar ? Quite clearly magical and a heretic, likely to burn me at the stake. Steam power pushes steam through A turbine maybe ?
Lightening sky electricity. Get a bunch of metal and kites. Die.
Solar are LEDs. But instead of putting electricity into that light comes out, you push the light in to get electricity out.
First of all, no one would understand you, but how someone already pointed out, make a spool with copper and spin it. For bonus points, put a iron slab inside the spool
Edit: as someone pointed out you kinda need a magnet
Plain copper will get you nowhere. Adding iron slab also won't help. You have to have magnetic field to generate electricity
