I’d give laser pointers to Neanderthals. Even if they did figure out some useful application for them (maybe hunting?) they’d run out of batteries eventually.

      Fuck yeah, just give the ancient Greeks hindu-arabic numerals and watch them lose their minds. Teach Zeno calculus and watch him try to prove it wrong.

        Pretty sure the greeks knew about the hindu number system, they were neighbours for centuries. They just thought zero was of the devil and geometry was better that algebra and never adopted it.

      Imma come out and say it: they’re old timey versions of copper coils or orgonite pyramids. Gnosticism got kinda big for a while and people were buying curses and prayers and stuff from people to write on little bits of broken pottery like little curses you’d write on scraps of paper in middle school. Somebody out there figured out how to weld little metal sacred geometry figurines and people were buying them because they look cool and some of them probably thought they’d cure dysentery or whatever.

    Give them a 1/2 meter cube of stuff. Tell them its a device that summons god. Only true believers can do the ritual, heretics will die.

    I pretend to pray, my partner flies in with the FG 204, 2nd Edition Ver. 2.31, I leave.

    Its just a block of plutonium. Trollolol

    (Sorry, my evil alter ego took control, I wouldn’t actually do that, that’s so fucking chaotic evil)

      Humanity - civilised Greeks or not - didn’t have the metallurgical knowledge to be able to build locomotives and rails out of strong enough materials yet. Ancient Greece basically coincides with the Bronze age.

      You’d have to not only bring (knowledge of) steam locomotive tech, but also every single bit of iron tech required to build one. You could skip the requirement for rails by opting for a steam traction engine, not a full locomotive, but those are far closer together in technological ability.

      None of this factors in the propensity for steam boilers to explode, which you may or may not consider important.

      There’s a reason we were still using beasts of burden (horses, oxen, etc.) for traction until the 19th century.

    After further consideration, I would also give them a Solar-Powered TV that plays nothing but a Video of Hatsune Miku doing Fortnite Dances
