Just spin a magnet in a copper coil.
BOOM! Electricity.
How do you make a magnet?
Coil a lead wire around a big full metal cylinder (must be magnetizable) and attach one end to a big ass antenna and the other in the ground, then wait for lightning to strike the antenna. Although the amount of power will probably melt everything.

Alright it’s decided, you’re the guy we’re sending back to teach Jesus how to build gaming PCs from scratch.
Fucking magnets
Expose molten ferrous metal to … a magnet.
Welp…
Magnets are created by running an electrical current through a material, so there is no need to have a ‘first magnet’. This is happening ‘naturally’ in the earth core, in the sun, and in other stars. (https://physics.stackexchange.com/questions/565245/how-was-the-first-magnet-made)
So you need to look around and find some magic rocks.
Natural magnets, called “lodestones”, were found in iron ores (magnetite) from the ancient region of Magnesia, hence the name “Magnet”. (https://physics.stackexchange.com/questions/615500/how-did-magnets-first-come-about)
Maybe the sword with the stone was just a big lodestone with a sword sized hole in it. Just throwing that out there.
And one more cool fact…
Based on his discovery of an Olmec artifact (a shaped and grooved magnetic bar) in North America, astronomer John Carlson suggests that lodestone may have been used by the Olmec more than a thousand years prior to the Chinese discovery.[23] Carlson speculates that the Olmecs, for astrological or geomantic purposes, used similar artifacts as a directional device, or to orient their temples, the dwellings of the living, or the interments of the dead.[23] Detailed analysis of the Olmec artifact revealed that the “bar” was composed of hematite with titanium lamellae of Fe2–xTixO3 that accounted for the anomalous remanent magnetism of the artifact.[24] (https://en.wikipedia.org/wiki/Lodestone)
I feel like you could still give science a head start by giving them rough ideas of how things work, like penicillin and steam power and whatnot
Even if you don’t know all the ins and puts you can give them something to go off of to develop the technology faster
Ayyyyy gotta love some quick typing typos lol
If you couldn’t prove it, things probably wouldn’t go well for you.
I take these two completely different looking rocks, dig a small hole between them, and pee in the gap.
Electrolytes! It’s what every caveman craves!
won’t going back in time spread coronavirus and other diseases?
More likely you’d catch the bubonic plague and die within a few months
We’re the descendants of bubonic plague survivors. They haven’t even gone through last year’s flu.
Only if you are sick at the time you go back. The occasional 1 1/2 viruses aren’t going to survive long enough to infect anyone.
Forget mathematics, logic and philosophy. Teach them about Jeebus and establish a solid patriarchy. After that make a shitload of McDonald’s and Facebook.
How dare you not Starbucks their Walmarts! Google is going to Microsoft you!
Skip electricity. That doesn’t matter until you can make reliable turbines with copper and magnets. Go to steam power first. It can move things. Which will speed up delivery of copper and magnets. But also teach them to plant trees. Every tree removed to smelt and power a steam engine needs to have three more planted. You could start greening the Sahara before umit even starts collapsing. “he sure had this steam thing figured out. I guess we will forgive him for all these useless trees”.
I read they knew about steam power for a long time but couldn’t make the engines / containers / doohickies strong enough to contain the pressure.
That’s true, it was cannon technology that allowed steam engines to be created

What is the ‘Carnot cycle’? - I don’t know
A great master plan to prevent climate change, although the industrial revolution will start 2000 years earlier, so I’m not sure it matters
The sooner it starts the sooner I can get back. :)
Is there a guide for DIY steam engines?
Boil water in a closed system that uses steam to move a paddle on the inside that is on the same shaft as a wheel on the outside. That’s the basics. Everything else is just variations on the theme. The higher the pressure the faster it goes and more torque you get.
I guess I forgot to mention that once the steam moves the paddle the steam needs a place to cook down and go back into the boiler.
For better efficiency the steam should be used twice, in a high pressure circuit first and on its way back to the boiler through a low pressure circuit.
I like my steam very well cooked. I let It cook down for a couple of hours.
You don’t find that it starts to taste like cardboard?
Nah, for a first step implementation in stationary applications, you can have a steam machine run an open circuit. Steam expands, performs work, exits through a valve. Just keep the water tank filled. Less efficient, but it would work. The return loop is an optimization for the next stage :)
Pop Pop boats are really simple steam engine systems.
Yes, electricity would be magic for medieval (and prior) people. Spells trouble for you.
But no, Steam… the principle was known and seldom used by ancient greeces and egypts already, but they couldn’t really utilize it, because metallurgy wasn’t there yet.
And Sahara was almost green 1000+ years ago, lots of oases.
Go to steam power first. It can move things
They had steam power over 2000 years ago, they used it in temples and as toys to amuse the rich.
Slaves could move things, and were much cheaper.
Couldn’t you just rub something with wool and demonstrate static electricity that way?
I think they knew about that already.
And then what?
Profit?
The prompt is fulfilled, cut to credits
If this concept intrigues you, I recommend watching Dr. Stone.
Master of never used science.
But first, you need all the guns (and other modern weaponry) to gun down anyone trying to kill you. Might be useful to make them listen to you as well.
Hopefully they will understand modern day English
found the redneck.
apparently common sense survival in an unfamiliar hostile place is a sign of being a redneck
First thing coming to mind being how to fight other people is very redneck, yes. Only emotionally retarded people think like that.
Eh. Like 90%+ of everybody who ever lived in pre-Industrial civilization was a slave or a serf or something like that. What does that say about the other 1% that “owned” them? And if your goal is explicitly to bring lots of revolutionary technologies, you’re probably going to disrupt a lot of established power structures. People in power don’t tend to take kindly to that, and as the ultimate outsider, you’ll be the perfect scapegoat for anything that goes wrong.
It’s dumb to think only about fighting, and this specific scenario isn’t something that you’re ever going to be able to win through brute force alone. Also, using guns “to make them listen to you”, as the original comment said, sounds pretty evil depending on how it’s done. (E.G. Menace and threaten anyone questioning you: Evil. Gain favour with the royal army by providing guns, then ask for funding for medical research: Less evil.) But ultimately, it’s reasonable to be prepared for other people to act in bad faith.
You must be fun at parties 🙄
I’m impressed at the strength of the guy’s upper arm that he’s sitting on.
This reminds me of Dara O’Briain’s bit about going back in time and thinking you’ll impress the greatest minds in history with your future knowledge but it falls apart quickly.
Go back in time with a 4th grade science book from 1997 and be a fucking wizard.
This was the (side) plot of Army of Darkness
He basically was a wizard in Army of Darkness. He made a robot hand in a blacksmith’s shop.
I thought everyone learned how to make electricity at home with a potato at school…
I feel sad for the fundametalists sometimes.
Same tbh. Christian homeschooling is very common where I live. It’s borderline abuse imo
