>Japanese highschooler uses his 21st century command of science

They could probably figure something out. Pioneer sterilization and hand hygiene in the medical field. Theres a surprising swathe of day to day knowledge thats actually fairly recent.

>>150400279

Hygiene and sanitation and just germ theory in general took a REALLY long time to get accepted. John Snow spent half his life trying to convince people that cholera was spread by 'something' in the water and not by noxious smells.

As for the guy who introduced hand sanitation to hospital settings,

>Despite various publications of results where hand washing reduced mortality to below 1%, Semmelweis's observations conflicted with the established scientific and medical opinions of the time and his ideas were rejected by the medical community. Semmelweis could offer no acceptable scientific explanation for his findings, and some doctors were offended at the suggestion that they should wash their hands. Semmelweis's practice earned widespread acceptance only years after his death, when Louis Pasteur confirmed the germ theory and Joseph Lister, acting on the French microbiologist's research, practiced and operated, using hygienic methods, with great success. In 1865, Semmelweis was committed to an asylum, where he died at age 47 of pyaemia, after being beaten by the guards, only 14 days after he was committed

Having knowledge of something is one thing, getting people to accept and acknowledge it is another. Especially something like germs which can't be seen without specialized equipment.

Another thing is converting something you know about into a marketable form. So lets take your hygene into account. You know about using soap, killing germs, etc can prevent spread of infectiona nd disease. Now how are you going to profit off this? People aren't going to go "Of course! We should be washing our hands! Here's a big basket of money as thanks!".

Are you going to sell soap and disinfectants? Do you even know how to make disinfecting soap? Is it something that others are going to quickly catch onto and sell their own better versions faster than you can produce your own products for sale?

The average highschooler doesn't actually know shit about how to make most of this stuff or understand more than just the general idea behind a lot of it. Hell, I don't think they could even market and create shoe laces, let alone weapons and medicine.

>>150400529
>Did you skip the part of history class where they explained to you how to cure Small Pox?
For years after Edward Jenner introduced vaccination, people were still pooh-poohing him and sticking with tried and tested inoculation. It's hard to get accepted when you're fighting against institutional inertia. But in many of these stories their 'genius' ideas are often accepted almost overnight.

>How about the part where you have a modern understanding of the causes of disease and sickness?
Good luck proving it though, unless you have the years to spend on independently designing and creating a microscope that will let you see bacteria, followed by parallel reconstruction of all the work of Pasteur and Koch with only the basic knowledge of what it was that they proved. And then you need rich and powerful and influential backers to push your theories as the accepted ones in the scientific community.

Also it's still going to cost trillions of dollars and decades of work to reconstruct your capital city to have a proper sewer system instead of just letting the shit flow through the streets.

Highschoolers ain't got no time for that.

>>150400804
By studying birds and hundreds of failed prototypes and experiments.

>>150400804
Exactly, it took years to figure out fixed wings because people could only think to attempt to imitate nature i.e. flapping wings, and then it took even longer to figure out how birds actually control themselves in fight.

I wish we could just fly.

>>150400685
While profiting off a new idea is very difficult and requires conscious effort, its something people have managed to do for millions of years.

I'm not saying a high schooler is going to be able to destroy all competition in 10 minutes, but if a highschooler knew about something like: "Production of Disinfecting Soap" or "Antiobiotic Production", with just a little ingenuity, a lot of time, and some help, he would probably come up with ways to demonstrate effectiveness and make a significant profit.

With regard to germ theory, some of the early biology theories were just so far out there its kind of unbelievable. It didn't require a particular genius to disprove [ https://en.wikipedia.org/wiki/Spontaneous_generation ], and the experiment setup if actually kind of fucking durrrrrr if you know anything about germs.

>>150400752
But that's basically it. He knows concepts or what should be possible, but he has no actual way to implement the idea and like most other things needs to rely on others to fill in the gaps.

This thread reminds me of the episode of New Getter robo, where the pilots get stuck in the past, and one of them becomes a farmer.

Most isekai have magic, so they allow the highschooler to just put out the idea and magic serves as the power source to let time travel happen.

Some isekai have commented on this. In Overlord, there's the Boastful Sage who tells everyone about wonderful items but can't explain why they look like they do, or how they work/are built. Magic only partially replicates what he says.

>>Japanese highschooler uses his 21st century command of science and technology to transform a primitive society meme

I have never actually read a isekai where the protagonist uses actual science to revolutionize shit.
90% of the time he simply uses magic mixed with some science like how a lot of isekai make magic guns or magic engines and shit.

Even the fuckign isekai where the protagonist has a smartphone with access to the internet doesn't actually has him using science. Seriously, you'd think the one time it would be justified for a hikkineet to revolutionize a medieval world would be where he has a magic phone with google-sensei but the author fucking wastes that shit.

That's ridiculous. Military utility trumps "muh change". Almost from the beginning of people understanding the power held by the atom, people were considering its potential military application. That's like saying "Molotov cocktails are not used because bottles are for drinking from".

Innovation leads to things like using the toxic gases created as a byproduct of industry as a weapon on the battlefield.

>>150401585

Depends on the culture.
Also to answer OP a lot of modern technology that is not that complicated to invent, it just took centuries of blind luck to actually stumble upon them.
See: steam engine, magnets/electricity even the basic principles of computers.
Anyone here could probably "invent" a steam engine and a basic power generator. The bigger problem would be using that electricity for things other than heat, motors and lamps.

>>150401962
Steam engines had been invented for hundreds of years, but they really sucked, tended to explode, and had no practical utility. They only managed to catch on initially in Britain because they could be used to pump water out of coal mines of which Britain had many to get more coal, where there was an easy supply of shitloads of coal to fuel the shitty inefficient engines and where the water cooled them and prevented explosion, and this provided the impetus to create better engines that only later were different uses found for. It was as much environmental, social, and economic factors that allowed for the Industrial Revolution as scientific geniuses, which a high schooler would have trouble creating in a matter of a few short years while he is still a teenager.

>>150401077
I could design the parts required for a bicycle, which could advance technology several hundred years because of things like the bike chain and gears.

What could gears and chains do? Indoor semi-powered fans. a complex gear system of windmills powering indoor fans for air circulation int he summer time and better bellows for forging.

What else could chains and gears be used for? Miniguns. Gunpowder is sulfer, saltpeter, and charcoal, then all you need is iron barrels, which are easy, relatively speaking. With the advent of gunpowder and guns, you introduce rifling at the same time, now instead of mini cannons that you have to aim and hope, you aim and the bullet goes where you aim, suddenly the world gets a lot deadlier and less resources are wasted on armor because its useless against a bullet.

Really, your question is stupid not because of the way its asked, but because of what its NOT asking. Its one thing to know how to explain shit, its another to explain shit in a manner that lesser minds understand. You can tell people that saltpeter, charcoal, and sulfur make gunpowder, but if they dont know what sulfur or saltpeter are, look like, or smell/taste like its useless information. You ever tried explaining why the sky is blue to a child? They dont understand concepts like electromagnetic radiation or light wavelengths.

You probably have a very (emphasis on very) general idea of how they work, most likely from your highschool and maybe a few empirical observations from your everyday life. That's still pretty far from being able to invent them, only give a few ideas at most unless you go on and become a scientist in the past which should still take years of dedication.

Work is still work, even when you can avoid wasting time on fake stuff.

I know how to make gunpowder (shitty blackpowder really), so as long as I get transported to a world that doesn't already have guns or an equivalent I'm pretty set. Just show off my exploding powder to a few folks, avoid getting killed by frightened peasant, and earn the attention of a rich patron who wants to use my "invention" for war or construction or something, and I'm set.

The general problem people have when they say "Well if I was in a medieval setting I would just make X!" is that like you said, they don't actually have any detailed knowledge on how the thing they want to make works, or if they do, they forget that often most modern tech requires a lot of other more basic tech and social conditions to work. That's why it's best to start with simple stuff that also useful to the people who's world you just landed in. Stuff that ideally you could make your self or easily demonstrate to people. Chemicals and simple tools are good for this, but more complex ideas like, new farming techniques or health innovations are terrible because you have to go around convincing all the already knowledgeable people in that world that your ideas are better, which is difficult if your just some random stranger from nowhere.

Unless by "from scratch" you mean you literally mined the raw materials from the earth, smelted the ores into proper metals, refined oils into plastic, made all the other materials, personally shaped them into the proper parts then put them together into a working radio, then you're just as full of shit as everyone else here.

The pre-made radio parts aren't just going to be sitting around for you to put together like a puzzle.

This is what annoys me most of everyone being so fucking stupid in this thread. They're only thinking 1 layer deep. Yeah you might be mildly familiar or even knowledgeable about how some parts of some modern device or idea, but every one of those parts is just the tip of an iceberg, the culmination of dozens or even hundreds of years of research and work from people all over the world. Recreating all of that truly "from scratch" would be nigh impossible even for real experts, let alone stupid cartoon watching nerds who delude themselves into thinking constantly insulting strangers on the internet makes them smart.

It's not being knowledgeable. Nigga just comes and says "yeah I processed everything for some reason you know I swear". No details or anything.

Then you'd have weird cult that would either catch on amongst the poor and have a shot at becoming a real religion, remain small and obscure, or be destroyed for going against the orthodoxy.

Christianity was a religion that most got lucky with a lot historic circumstances. There's nothing inherently superior about Christianity that lead it to conquer so many other religions, there were other religions in the west throughout time that had a similar message to Christianity, but Christianity lucked up with coming up in a time of great distress and decline in a massive continents spanning empire that was generally pretty tolerant of kooky religious beliefs and customs and ensured that transmission of information was fairly easy due to robust road and trade networks.

Christianities a big case of right place, right time.

Math and Sciences requires you to convince a bunch of rich assholes that you, a nobody, somehow has amazing knowledge they don't, sure maybe you could demonstrate it to them, but it's unlikely you'd get the opportunity to do so, since you're a nobody, and even then they might not believe you if the knowledge that your teaching contradicts too much of their established knowledge base. Remember Aristotle, and man who live 2500 years ago, was considered the basis of all scholarly thinking until like 200 years ago, and people who contradicted him usually faced persecution of some sort.

For literature, well I don't know how that's suppose to help you since medieval societies are well know for high literacy rates, and writing was generally reserved for the religious, or rich assholes with lots of time on their hands. It also requires you to already know how to write, unless you plan to just plagiarize other authors, in which case, good luck trying to get people to like Shakespeare with out proper context.

Yeah that's a bit overkill, you don't really need to go back in time for that

In shieldbro all of the summoned heroes past and present are or were Otaku. Since Otaku in japan means something different than in the rest of the world there might have been heroes who knew to the point of obsession how stuff worked and why.

Because of this, there's one place that's far more technologically advanced than others in the other world. Where heroes are invited to live in, share what they know and spread their lineage since for some reason the ones that get summoned have the best genes. Most of the nobility there has descended from heroes of the past. Of course there's a lot of power struggles in such a country but that has never stopped progress

They have a lot of modern stuff like paved roads, drainage/sewer system, cars, tanks, planes, advanced firearms and i'm not sure but they probably also have working internet but i doubt that one.

Yeah, so start small like the internet did. Get a grant from the king to set up a single line between his capital and an other important city for administrative purposes.

Lay more lines to cope with increased demand, allowing more supply. Keep going.

Nah foods pretty bad but I just didn't have space to finish typing. The thing about inventing new foods is finding a market for them. You could be the best chef on Earth, but being transported to another world or to the past means whatever reputation you've garnered for your self is out the window, and it's not like you can just start a restaurant. The idea of going out to a place specifically to eat some one else's food rather than just cooking at home is an pretty new idea, and in a medieval type setting no one is going to have the time or disposable to bother with it. Usually if a place served food it was as part of some other services such as in a Tavern or Inn, which are difficult to obtain and/or start working for due to guilds and shit. Even outside of that you have to remember that your list of ingredients would be very limited. Many of the common cooking ingredients used today (corn, potatoes, tomatoes, etc,) are new world crops that didn't exist in Europe or Asia, and outside of Asia, most spices were rare and expensive so you're foods going to have limited flavor compositions, and if you're in some entirely different world they may have shit your have zero idea how to cook. Then there's the problem of storage, most shit in the past would be heavily salted, brined, or honeyed to prevent decay after harvest, so for most of the year you're working with ingredients that are way too salty or way too sweet. It's doable sure, but really tough.

>>150404757
Where are you getting the food from? and with what money? Do you have permission from the local guild/noble to sell your good in the market?

That was mostly and effect of the Industrial Revolution, cities before that, while not models of cleanliness, weren't the writhing cesspools of death and decay that 18th and 19th century cities were. Generally before that city population decline happened due to economic reason (and the occasion plague, but that wasn't really the cities fault)

Hell if you lived in an old Roman city you likely had a working sewer and running water.

the average present day human would be immune as fuck to those diseases.

The real twist is that all of the diseases inhabiting your body that aren't strong enough to kill you, would be much more evolved that the diseases of the 1000yrs ago, and would run rampant upon any society you pass through.

It would be like that Katsuhiro Otomo short, Stink Bomb, with you killing everything you come across.

Electricity would be fairly easy to do. All of the materials would be available to produce metal-acid batteries. Electromagnetism is fairly simple to explore at that point, which would introduce the possibility of magnetizing iron to use for power generation in water wheels and windmills. This could be used to create simple heating elements, electric motors, lightbulbs, water pumps, etcetera. I bet they would also be interested in using electricity to execute people.

At that point, people would be more believe me when I talk about concepts like germ theory and atomic theory.

I could also introduce things like distilling gasoline from oil, combustion engines, and steam engines, though a lot of the equipment there may also necessitate the construction of precision lathes and mills beforehand.

No they wouldn't. Especially the diseases, like smallpox, that we've basically eliminated.

>The real twist is that all of the diseases inhabiting your body that aren't strong enough to kill you, would be much more evolved that the diseases of the 1000yrs ago

That is not how evolution works, the diseased aren't more evolved, they're just different due to outside stimuli, which means your body has built up immunities to the current iteration of the disease and not the past one, so while you might have some effective immunization against diseased that haven't changed much in 1000 years, you still get sick from a ton of others.

You don't know much about diseases.

They don't work like fucking power levels. It's not just a cold war of diseases and animals growing in power level over time like
>Haha! These diseases from 1000 years ago only have a power levels of 200! My modern day human disease resistance powerlevel of 15,000 will defeat it with ease! I'm invincible and immune to everything in this time!

They mutate and become fundamentally different. Your body has never been exposed to the variety of diseases from then and you'd be vulnerable as fuck to them. Plus there's diseases from the past that don't exist any more, meaning you'd have ZERO exposure to anything even remotely close to them.

Like, smallpox is an officially eradicated disease. Do you honestly think that's because everybody on earth is just immune to it now? Cause we're not, the fact that nobody on earth has been exposed to it before means we're actually more vulnerable to it now than ever, and it would wreck people if it ever came back.

It's funny how rarely that gets touched on in medieval fantasy. Guilds were a huge pain in the ass to deal with for anyone trying to start a business or trade in most cities sine they were usually very protective of their monopolies.

>>150405149
> Even if I did, why would they beat me up for selling something with no real competition?
Because you didn't go through the proper channels. Guilds usually controlled a lot of the trade in most towns and they were very protective of their monopolies, so new guy coming and even maybe trying to get in on the game was a major concern. Now if you were just selling stuff to Guild members it wouldn't be a concern, but you're trying to establish yourself as an independent merchant in their area, and they won't appreciate it.

>I'm not undercutting their shitty crops or something and pissing off the medieval mafia by stealing their profits.

Merchants don't sell crops, farmers do, and I'm assuming you're selling some kind cooked good on the streets, which is a problem for all the tavern and inn owner that are in the guild as they would much rather people enter their establishment and eat the food they're making. Also I assumed you went to at least a moderately sized town as you're local dirt villager doesn't really have disposable income.

>Isn't that what merchants fucking did?
Not really, they went to towns to sell their good to other merchants in the town that would use them to make something else or otherwise sell them.

Once again, what was the point of all that? Some hypothetical guild guy walks up to me, tells me I can't sell there, I tell him I'd like to either join the guild or sell to the guild. I'm not going to get my throat slit for trying to sell some good food to peasants on the outskirts of town. And I just said I wasn't intruding on any monopolies, I'm selling a NEW product. Aka food that doesn't require you to stay at an inn for, fast food (which you fucking said didn't really exist)

And yes, that is what lots of merchants did. They crossed vast distances to trade for shit with China or India or Africa.

>>150402172
The first steam engines sucked because they were condensing steaming to create a vacuum to exert force. The water cooling was to cool the steam to condense it.

And yeah boilers exploded all the time because of a range of reasons, but people still used them because they were so much better than anything else.

If you started your industrial revolution with a steam pressure driven piston and crankshaft rather than a condensing vacuum you just cut about 100 years of development off, and can move directly into useful steam power for static or locomotive forces.

Combine a working knowledge of electric generators and basic electric theory and you now have a viable prime mover that you can attach to a generator to make electric power that has wide ranging applications from powering machinery to chemical processing, to even just electric lights.

Depending on the tech level you can even jump start hundreds of years of trial and error to get right to efficient steel production with the proper furnace design and metallurgy.

>>150402212
>Probably not you actually need to kinda know chemistry for that.

Not really. It is actually as simple as a zinc plate and a copper plate with a brine soaked rag between them.

The lead acid battery is two sheets of lead, one lead the other lead dioxide and sulfuric acid. Sulfuric acid dates from about 80AD. (burn sulfur and saltpeter plus steam to make it)
You now have a rechargeable battery.

True. You might do something like suggesting the lanteen rig, watertight compartments,and the rudder though, which is easy to make a matchstick model of and far superior to the square rig. Sell the idea to the Shipwright's Guild, starting with 'it can sail even with a hole through it' and 'you can sail against the wind' and 'a hole in the ship doesn't sink it'. You can also do the same with an astrolabe as long as you know the equator-pole system and some trial-and-error, and invent the compass and chained gears as well as the wheelbarrow which wasn't a thing in Europe for some ungodly reason.

see here though, the ONLY reason to use crappy muskets over mastercrafted longbows is because they allow you to raise large peasant armies with only a few days of training, who can then line up and volley fire and massacre knights who have trained for years, whereas longbowmen are basically born to the role and train for decades.

Why is the lord interested in arming his serfs unless it's literally the warring states period and he absolutely needs a large armed peasantry right this moment? And how do you create the manufacturing infrastructure needed to sustain the use of tens of thousands of muskets en masse across a sustained campaign?

>medieval rulers were all scheming retards with no foresight whatsoever
Considering how fast large siege cannons spread in Europe, I don't think the average medieval king would be so suspicious of muskets.

>10,000
Medieval armies werent so large. Even if I only manage to arm/train only a thousand plebs per year, they'd still be a gamechanger. There is 90% probability that something would go wrong, and I'll get killed or kill myself. But considering that living in the XIc. is pretty much hell on earth worse than death, I might just give it try.

Because you'd like air conditioning, and more importantly the busty redhead Ninth Imperial Princess who can spam country destroying spells by the dozen and is the equal of the entire Demon Army combined doesn't like you and needs to be impressed.

A collage student of engineering could pull it off, even a high school student studying to get in to one might.

A student who's a medieval history buff could also do it, but wouldn't get as far down the tech line. (irrigation, crop rotation, gunpowder and cannons, basic sanitation and medical practices, central banking, windmills, the screw, cowpox immunization.) that kind of stuff

You know what really bothers me about most isekai fantasy settings?

How most of them are "it's like medieval Europe, but with magic, BUT NEVER THE TWAIN SHALL MEET". Like, how the hell does a society where magic is ordinary and commonplace end up with the same technological progress as the Holy Roman Empire? A civilization where humans can shoot fireballs out of their hands at will should obviously veer off in a wildly different path of development than boring ol' mundane medieval Europe.

Water magic alone would render most cleaning tools pointless, but somehow you'll still see the maid character running around with a mop and rag.

Because knowledge of the tensile strength of steel will totally come in handy in a world where steel doesn't fucking exist yet.

That's what my wind familiar is for though.
Magic sure is convenient, isn't it?
