You are sent back in time to ancient Greece with a smartphone containing the most recent wikipedia data dump. However, you only have 8 hours of battery life and you left your charger in the year 2016.
What do you do to advance ancient Greece to at least a 1950s level of technology?

Make a charger.
EE here.
I think not knowing ancient Greek would be a problem.
I believe the language barrier would be insurmountable.
It'd be possible to learn a language by immersion, but that's something that takes far longer than 8 hours.
Location:
255 B.C. Syracuse Greece.
Phone Specs:
android with root access
has python and GCC installed.
has accelerometer, gyro, proximity, compass, camera, and barometer sensors typical of a smartphone
waterproof to 1 meter.
removable battery
A smartphone cannot hold all Wikipedia data faggot.
8 years, at least.
DIY phone battery charger..
It is hypothetical loser..
how do you make a charger? Keep in mind you didn't take your multimeter with you, you won't be able to buy insulated wire for a very long time, and you are basically penniless.
Turn off the phone, learn the language and in the interim before fluency teach them all of the things I know through my education. When I'm fluent then I'll turn it back on and get a small army to transcribe the most important aspects.
Shit senpai, that is what the 8 hours is all about. Can you beat the time?
And even if one were fluent in the language, the locals might just think the hypothetical time traveler was not exactly right in the head.
The data dump of the english wikipedia takes up about 59 gigabytes. This includes all text, but no talk or edit history. Images are included too, but at a low resolution.
blog.wikimedia.org
Seriously try it, it's pretty great.
How am I penniless? With every great discover in my head from Kirchhoff, Faraday, Gauss, Edison, Tesla, Coulomb, Henry, Ohm, Fourier, Dirac, Euler, Bell, just to name a few, I would be an emperor's greatest asset Athens could every want!
They could spin thin copper or aluminum wire and beeswax is all I need for insulation/dielectrics.
Remember that turning off the phone will not make the battery last indefinately.
I forgot Ampere too
If you just wanted the science and engineering portions of Wikipedia, it'd probably fit on the built in storage of a smartphone or the average MicroSD card.
Wait, just wikipedia, or can I use my own knowledge?
Because you aren't gonna do much engineering with just an encyclopedia.
how much porn is on my device?
Engineer here.
Teach those faggots how to suck cock.
Don't need an EE degree or modern tech to make a crank generator. You don't even have to build new batteries. (Although the ancient greeks were making rudimentary batteries for bronzing.)
Actually, how would one go about making a dc crank generator? I don't know how I could make a diode to convert from an ac generator I could easily build.
I'm not an engineering student.
>> it'd probably fit on the built in storage of a smartphone or the average MicroSD card.
Again, the ENTIRETY of the english wikipedia compressed with limited image resolution takes up 58.7 gigs. At least it does on my device.
Are you telling me the average SD isn't 64 gigs?
all thumbnails included in the english wikipedia.
I know enough about EE to figure out basic electronics, so instead I would go make sure I know exactly how to build guns. Muskets, possibly a crude shotgun.
>>generator
how do you make sure you are generating the correct voltage?
You wouldn't be able to make anything without permanent magnets and I don't think ancient Greece had very many. You would be stuck with batteries. These batteries would be huge to even get a few amp hours.
>To actually charge your iPhone (warning: this may damage your phone), you must string at least 12 of the battery cells together and use multiple nails in each fruit.
>WARNING: THIS MAY DAMAGE YOUR PHONE
Oops! You have made a mistake constructing your lemon cell battery and now you are now stuck in ancient Greece with a brick.
I thought the most common was 32GB.
Anyway, if one were to shave off the pop culture stuff alone, it'd probably take a huge chunk out of that 58.7 GB.
not really since it wont be at such low power, that it wouldn't even damage or trip any of the over current/voltage protection on the phone
Start slow and crank faster until it no longer says "slow charging."
But I still don't know how to make a diode.
So how are you going to make a generator?
>> diode
it's gonna take a lot of work to make a diode that's good enough. Wikipedia says you might be able to make a copper oxide rectifier or electrolytic rectifier though.
But you don't need one if you make a dynamo. You get DC directly. One can also make self excited versions that don't need magnets. Of course you still need to get enough resources to build one.
>But you don't need one if you make a dynamo. You get DC directly
good shit you been smoking ayo
Copper and wax, just like Maxwell and Faraday did.
I should look up how to make a dynamo though, since you say it's easier and I could have this hypothetical scenario happen to me any minute.
Nevermind. Dynamos are trivially easy. That's the way I would go.
>how to generate electricity
>telephones
>computers

>recycling
>fusion power
And then give them the everlasting command of inhabiting every planet in the universe.
It's one thing to know the theory and engineering behind something and knowing the industrial processes behind fabricating it.
The best you can hope is to make a primitive battery. The average engineer knows nothing about the subtleties of smelting steel or refining or fabrication or whatever.
>giving Greeks anything
Even in antiquity they need handouts, pay your fucking debts first then we can talk.
Didn't the ancient Greeks speak English?
>you left your charger in the year 2016
What a mistake to make, with all those wall outlets in ancient Greece!
Fuck that.
I'd exchange the phone for some shekels and Greek babes.
greek "babes" are fat, hairy and have big noses
A simple steam engine should be enough for starters
came here to post this
How hard would it be to build a solar charger?
>American "education"
this was my first thought, but you'd need silicon and shit
not exactly easy
... no.
But if you know modern Greek, it _may_ be _somewhat_ easier to learn ancient Greek.
somewhere on wikipedia has to have the instructions for basic circuitry for voltage testing, and insulated wires are fine, just use cloth wrappings.
besides,
>penniless
if you can survive long enough using minor tricks and whatever from your store of knowledge, and you can build enough of a nest egg to start an aluminum mine, then you can build an electrolytic cell to produce aluminum cheaply in vast quantities and be the god-baron of the ancient world
the medical section of wikipedia contains:
>lists of critical drugs for modern medical infrastructure
>the components and synthesis outline for each drug
>information on organic chemistry
>natural sources of drugs if available
>basic medical techniques and diagnoses
>modern scientific knowledge on etiology of disease
as long as you can overcome the language barrier, you can start an in-house medical clinic and move on up from there.
as long as the battery is full, you have enough time to copy out the basics of that information onto paper so you always have access to it, plus a couple hours for emergency and future use.
Just write out euler's equation. EE invented. Invent calculus. Invent algebra. Invent ... wait it's 1950 already. why do we need a phone again? oh right its there for low IQ people
I'd just give up after 4 hours and just show them the several memes I've accumulated on my phone
In 8 hours with wiki there is enought possible to build charger from batteries from elements there...
Another thing is they already got that charger, mountain is called olymp, its a house in the olive forrest, always.
Fucking top kek
Youre a dumbfuck OP.
Manufacturing a solar cell would probably be the hardest way to generate the required electricity in the given circumstances.
dumb amerifat
lel
Still you can put a mechanical rectifyer in the dynamo and then maybe a spool in lieu of a cap.
The Greeks had lodestones- natural magnets, if a bit weak. Still think going the lemon battery route might be a better bet though.
The new lead iodide perovskite cells are ridiculously simple to make with some simple chemicals. They're not very durable though.
en.wikipedia.org
> Perovskite materials such as methylammonium lead halides are cheap to produce and simple to manufacture.
en.wikipedia.org
>Methylammonium lead halides (MALHs) are solid compounds with perovskite structure and a chemical formula of CH3NH3PbX3 (MAPbX3), where X = I, Br or Cl.
en.wikipedia.org
>These compounds are usually prepared by combining equimolar amounts of methylamine with the appropriate halide acid.
en.wikipedia.org
>Methylamine is prepared commercially by the reaction of ammonia with methanol in the presence of a silicoaluminate catalyst.
simple stuff.
I know pretty much shit when it comes to electronics, but could one build a generator out of copper and lodestone? Kind of like a reverse electric motor?
Not him but en.wikipedia.org
You don't need a magnet at all.
How do you build said steam engine?
oh it's really easy, it's just that it'd need to be really big
scitoys.com
aluminum is a good choice, but you need a decent amount of infrastructure for that
What you really need to start out with are things that are low mass and high value. Compasses would be pretty valuable in the ancient world. The Greeks were traders after all. Best case you get a lode stone and use that to magnetize stuff. Worst case you can make an electromagnet driven by some simple batteries. Compasses could also be used to make simple voltage and current meters.
Another thing that is very valuable in ancient Greece is dye:
en.wikipedia.org
Dye is literally worth its weight in gold and wikipedia has instructions on how to prepare a number of synthetic dyes. Mauveine is what we
en.wikipedia.org
Synthetic dye alone would make you a god-baron of the ancient world
So how you gonna make transparent conductors?
This, you can't be an engineer without charts and tables
why ancient greece and not the christian dark ages in europe? that's where the natural progression of science slowed down and was taken back by decades. why not start there?
because you'd get fucking lynched
>dark ages in europe
this meme is getting old senpai
>get work on a farm or some shit somewhere
>work enough to survive, then start growing my own little field of opium poppies
>extract the morphine, do a simple synthesis into heroin
>invent some DIY bamboo syringe or something
>get all of ancient Greece hooked on my "magic feel-good syrum"
>become richest and most power druglord on the planet
>smoke weed and fuck hot bitches every day
>throw the phone away
I would probably destroy the history of western civilization, but fuck it. by the time the chinese or whatever invade greece, i'll be long dead
1. Turn off phone, save it for porn.
2. Teach chemistry to the greeks
3. Become a king, ditch the pornphone.
I think it is impossible to do so with Wikipedia articles as they cannot provide you all the information needed to create all this cars, electricity and other technical devices. You can got only theoretical scientific knowledge from it and even this is very limited.
>What do you do to advance ancient Greece to at least a 1950s level of technology?
>Damascus jar
>call volta
>make battery/charger
>teach them hitler did nothing wrong,
Syracuse is in sicily
Give them memes
proper identification all iron ore types and coal.
how to make fired bricks and cement.
how to turn iron ore into steel, and do it in massive quantities.
triple expansion piston steam engines and steam turbines.
how to source potassium nitrate.
how to make gun powder. '
how to make wood based paper.
how to make pencils.
once I have all that written down and my phone is dead. I then compile it into a book and introduce the moveable type printing press(that I can do from my own mind_. I make copies of the books and distribute them to the libraries of the classical world.
>make sure the charge an electron has is denoted as positive
I wonder how much history would be changed if one could do that.
YES
I think success would differ significantly depending on when and where in ancient Greece one were to travel to.
Underrated post. But of course Veeky Forumsfags probably don't even understand that Sicily is part of Italy.
>Are you telling me the average SD isn't 64 gigs?
That's what he's telling you pham. I only have 32 gigs at well. Shouldn't have bought a phone without expandable memory though.
...
ITT: Americans
XDDDD
>dark ages wasnt real
haha dumb american xD
I have an S3. It's kind of a fossil already. And the battery probably lasts significantly less than 8 hours.
The ancient world kind of invented one: en.wikipedia.org
Enjoy walking to India to get your lemons.
Were there any citrus available in Greece back then? And even if there were, they may not be as effective as lemons.
I make a fruit or vegetable battery.
Syracuse was Greek.
It is about 80-85% the same
lol stupid american
You have for the most part, the whole of human knowledge, and you choose to make a battery that uses fruit as an electrolyte? You have all the information necessary to make a lead acid battery. I mean at least make a penny battery instead. You can use seawater, which is ubiquitous, for the electrolyte instead of fruit.
OP here, I am disappoint
...
I wonder if ancient Greeks would be more receptive to heliocentrism? I think they did work out that the Earth is round (from ships dissapearing over the horizon, etc).
