Tbf, I sincerely hope a lot of you understand the basic concept of a gearbox. Depending on how far back you go, a water wheel might be a pretty massive leap forward, and it might at least inspire other, smarter people of the time to work on theories of energy, and eventually electricity.

I would just bring an e-reader preloaded with Wikipedia and a solar charger. It would be treated as a relic for millennia long after it stopped working and would probably cause a collapse in the time-space continuum, but that’s just how I roll. 😎

If you can research how to make the original microscopes, bringing an understanding of virology would be hugely impactful.

Honestly, you don't even have to go that far. Just bringing back germ theory would massively advance the health and safety of ancient peoples. You might get a little bit of pushback trying to explain it to them though.

Germ theory was around for a long time before it was adopted because no one believed it.

Hello, it’s me from 2025. When are you from where germ theory is finally believed and acted upon by the majority?

People don't poop in their drinking water, it's an improvement.

I'm pretty sure that's just precision grinding glass and setting it at the right distances.

[–] JohnDClay@sh.itjust.works 2 points 1 month ago

But getting the precision shape to grind in can be hard. There was something about dripping liquid glass just right, but that may have been professional espionage to throw people off.

Viewing a virus with a microscope would be quite something.

[–] JohnDClay@sh.itjust.works 1 points 1 month ago (1 children)

Is the study of bacteria called something else? I guess just germ theory.

[–] AnUnusualRelic@lemmy.world 1 points 1 month ago

Viruses are extremely small compared to bactria. They typically can't be resolved optically. The study of micro organisms would be microbiology if you want to be broad.

I've seen enough isekai anime to know the way to make money is to show people clear glass, soap and the thing to pull water from a well without a manual bucket.

Oh for sure. I'm ready in case they pick me to go back in time and push human technology forward.

[–] AnUnusualRelic@lemmy.world 1 points 1 month ago

Good luck making gears though.
