If the sex is freely available, the men will come (no pun intended) Males are naturally attracted to sex. If sexual partners are easily found and freely available, they will travel. Your problem is actually that women will be left raising the children alone so the society would be better arranged to deal with single mothers than worrying about finding men. ...

Large dinosaurs are like elephants. Very strong, but the one thing they can't do is jump. Their massive body weight increases with the cube of their size, meaning that large dinosaurs are at the limit of what their body can physically support. Trying to jump is impossible for them. So forget about trying to build a strong wooden fence, build a ditch. That's ...

The practice in the first half of the 20th century was to wrap wire in cotton cloth, resulting in something like a shoelace from https://www.vycombe-arts.co.uk/onlineshop/prod_3699705-Double-Cotton-Covered-Copper-Wire-Reels.html Alternately, pass your wire through wood resin, which will leave a fine insulating layer over your wire, good enough for low ...

Beeswax Expensive mind you, anything food related is, and you're cutting into the candle supplies of the wealthy, but beeswax is a good insulator, easy to work, and available in almost any historical period. Not suited for high temperature use. Cloth Also available in almost any period, though harder to work with for these purposes most cloths are ...

You don't really have a problem (or at least not the one you think you have). The 'standard (literary) solution' doesn't bear much relation to observed reality throughout history. People travel if what they need isn't where they are, it's medieval so travel isn't that easy (takes a long time) so a lot of people won't travel back & will just stay where ...

I have done this. I have an interest in old technology and I recreate crystal radios, telegraphs and mechanical television. When winding the solenoid you can seperate the windings by winding thread of similar diameter alternately with the wire (I used waxed sailmakers' thread). Once you get to the end of the coil former wrap a layer of paper (I used wax ...

Your people lack strong metals. But they have gunpowder. https://vassallohistory.wordpress.com/the-fougasses/ Native Americans had gold, copper and silver but no smelting technology - no bronze or iron. One might make a passable edged weapon out of copper if there was enough of it, although stone is a decent rival to copper as regards weaponry. The ...

Why should there be any constraints needed? Napoleonic rifles were more than three centuries away from Turkish bombards. That should be plenty of time for your story to happen before the rifles arrive. Edit (revised answer): One way you could do it would be to have really lousy explosive powder available. So lousy that you need large quantities to fire a ...

Don't forget that real world humans hunted large beasts like mammoths and whales, just using spears, slingshots and fire (well, fire not for the whales). When it comes to projectile weapons, Aztecs can count on Atlatl The atlatl was a spear thrower, which produced greater force from a greater distance. Only the highest ranks were allowed these ...

Solar Charging Electro-magnetic Flechette gun How advanced is the most advanced world you've encountered? A Coil-gun is perhaps the most reliable weapon imaginable. It fires reliably underwater, in space, in mud.. The entire weapon can be sealed in plastic and it has virtually no moving parts whatsoever. It cannot jam, it doesn't misfire and requires ...

I don't see a huge problem here. In medieval times small villiges and towns constantly exchanged brides and grooms to evade degeneration (they didn't knew genetics, but effects of inbreeding are obvious) and manage population density. Two variants are possible. In not-so-religious society: So this particular town would just accept only grooms and provide ...

Best solution is to skip the gunpowder - too difficult to manufacture while traveling or carry vast quantities, and a bit of a pain to deal with anyway. Of course if you are relying upon the giant cloud of smoke to obscure you and the target and loud bang to scare the primitives off, then go with black powder, but honestly I would rather shoot them than ...

Man-eating dinosaurs should be relatively easy to keep at bay. A tyrannosaurus is a little under 4 meters tall, so it should be possible to hold it back with a good wooden wall at about that height. The villagers should keep a bell to ring when one is spotted to that everyone can run back to the walled fort to hide. Some flaming arrows might help persuade it ...

I'd recommend the Colt Pocket Percussion Revolver, possibly supplemented with a good muzzleloader (they've got easy-to-maintain modern ones now) for ranged shots. Sorry, I'm sticking you with ball and powder. Modern ammunition is pretty great, and not hard to make with modern techniques - but that's the thing. It's best with modern techniques to get the ...

Well, humans will be humans, so I have no doubt that they'll prevail. Because they already did in the past. Are the dino actively at war with the humans? No. This means that the humans will, first thing, learn to make their habitat dinosaur-free. Villages will be located in places with less dangerous predators, or in places which will be less accessible to ...

Your people lack black powder. It was never invented. Instead, they use steam cannons. Steam cannons have the [dis]advantage just right for your story: they really can't be made small, because of the whole steam thing. They have other disadvantages though - they are slow to fire, inconvenient and slow to reload, all the thing that I would say suit your ...

As opposed to men, animals are much more reasonable. They don't stubbornly go in places where they experience discomfort. Therefore walls, fires and smoke, topped with loud noises will be good dissuasive means. Keeping food away to remove any rewards for facing the troubles will also help.

Three factors enter into how well you can see a medieval city from the air at night. First, outdoor lighting is almost exclusively torches and oil/fat lamps (depending on the situation). These aren't very bright, compared to modern streetlights or yard lights. Second, due to cost, such lighting is likely to be as sparse as it can be, without too much ...

You have copper wire. You need a thin insulating layer so that one winding does not contact the adjacent winding. This is easy. Assuming you can produce the copper wire, you need to oxidize it in an acid solution. This will produce a green oxide layer which is insulating. Wind the green corroded wire with no overlap on each layer. Put a layer of silk ...

Lacquer is an alternative. It comes in many thicknesses. It's not too expensive. It can be painted on then heat cured. There are many different types that can stand up to a variety of challenges such as wear, heat, cold, even limited bending.

They don't need males. They are parthenogenetic females. Parthenogenesis is a form of sexual reproduction in which a haploid egg duplicates itself, forming a female organism. It is sexual because the egg undergoes meiotic recombination - this is the scrambling between chromosomes that is specific to gametes. But there is no need for a male or a mate, ...

The answer is to unshackle onesself from our customs of marriage and embrace polygyny or similar concepts. While it's not culturally acceptable in most modern cultures, in a culture where quite literally sperm is hard to come by, sharing would become a necessity. This would drastically decrease the number of males that the culture needs to bring in, and ...

Enamel Thin copper wires--like those used in inductors, transformers, motors, etc.--are enamelled. This is known in the modern world as magnet wire. Surely, you would prefer enamelled wire for your solenoid bobbin. We know that enamelled objects existed as early as the 13th century BCE. A concise history of enamel.

Bypassers are present in any country. An old tradition requires that they are given hospitality with full benefits, laying with a woman included. Add to this a yearly festival celebrating fertility where intercourse is encouraged as an offer to the gods, and you have not to worry about getting pregnancies. Last but not least, male cannot be born, but ...

Start a convent No procreation required. What you are describing can be accomplished by a suitably large convent, which even goes one step further than the limitations you posit by not requiring any procreation within its walls whatsoever. Convents in Europe have existed for centuries populated only by nuns, and "sustaining" their "populations" only by ...

All you really need is heat and knowledge. Copper and tin were very common metals in the world you describe, so the brass to manufacture ammunition is no problem. Gunpowder existed - but only in China - so the early Europeans just hadn’t found it yet. It was there. He needs to be really good at making very precise recipes from natural ingredients. We are ...

Bad material science: If you can not produce high quality metals, you may need bigger metal parts to use the same high pressure in the barrel for a high-velocity small bullet, thus making hand-held guns to heavy.

Get medieval, get a crossbow! A crossbow has simple enough construction and rugged enough parts that it should be able to handle a good deal of travel so that should fit your reliability criteria. The most vulnerable part would be the string but you could easily bring a few extras and as bows were developed by just about every human civilization at some ...

TLDR: Should be shocked, but otherwise fine OK, so with what we could compare it? Having in hurry to learn to program? May cause some headache and being generally annoyed, when everything crashes but people are generally fine. Discovering information that seriously change your ideological views? Well, stress can clearly go up. Some body parts may hurt ...
