Yeah, you can’t just lay down electricity, especially not practical electricity it requires a ton of diverse knowledge from many different studies. What I would do is give them the concept of using steam to power to spin wheels or create an engine. Then use gear ratios to show them how to scale it up. Idk if they had found neodymium magnets back then, but teach them how to use them to heat iron by spinning them on the end of a steam engine and you’re starting to cook with electricity.

Again, getting to electricity from there is still a whole fucking chore. But hopefully you could rely on science to advance way faster from your advances than if you weren’t there.

Actually, the most important thing you could give the greeks is the concept of the modern scientific method. That shit was invented so late and just skyrocketed science (literally) the moment it was refined.

Just write a book about everything you remember about a null hypothesis, randomized blind trials, control experiments, variable control etc. if you can squeeze any bit of statistics out of your brain, even if it’s just making a graph, you probably advance the world by thousands of years.
