Any group of people displaced from their own world and into another (that of an Alternate History
, an alien civilization, or simply Trapped in the Past
) will have people (or, stretching belief, even a single person
) that just so happen to have the knowhow to not only fairly accurately recreate their society's general level of technology, but to begin the march of innovation with little to no pause.
Basically, even cast into a society that's roughly at the equivalent of the Bronze Age, a group of a hundred or so usually randomly-assembled people (often military personnel) will be able to haul their new allies right into the midst of the Industrial Revolution within a year or two.
A sort of supertrope of Bamboo Technology
... while that trope relies on using local, low-tech materials to roughly approximate "modern" inventions, when Stranded With Edison, a group will manage to make themselves the real thing
... and possibly make it better
Occasionally a related trope appears, in which "stranded with Edison" means that the time travellers find a local wiseman or genius to work with, who alone would understand their ideas. That period's Edison, so to say. See also Giving Radio to the Romans
Not to be confused with Camping with Henry and Tom
, a 1995 play by Mark St. Germain in which Henry Ford
and Thomas Edison
are stuck on a road trip together in a Model T, along with President Warren Harding and a Secret Service agent (Which, in turn, was loosely based on real life trips that these men, who were actual friends, took together).
- Mark Twain's A Connecticut Yankee In King Arthurs Court (1889). After time traveling back to the 6th century, Hank Morgan uses his knowledge of manufacturing to build hidden factories that produce modern (1879) tools and weapons, thus industrializing King Arthur's kingdom.
Justified, in that Hank, while something of a drunk and a troublemaker, complains about losing his job as what would now be referred to as an industrial metallurgist and machinist. It is quite realistic that someone with that background and access to early iron-age materials and equipment would not find it terribly hard to produce steam-age technology and reproduce the relatively well-known and simple recipe for gunpowder; especially since he was transported to one of the regions where said technology originated, so he wouldn't exactly be short on raw materials or craftsmen with vaguely relevant expertise.
- In the Ciaphas Cain novel Death or Glory, their makeshift convoy/militia (made up from the rescued survivors/slaves from a town looted by orks) has just enough specialists to survive: a tracker to help them find water and supply dumps, a vet to serve as an impromptu doctor a technopriest to keep their vehicles running and enough former police, gang members and PDF troops to form a militia and a former not-so-Obstructive Bureaucrat to manage their supplies.
- Discussed, but averted, in Mostly Harmless: when Arthur Dent is stranded on a planet with an Iron Age culture, he initially thinks he can bring them civilisation, before realising that he doesn't actually know how to make anything. Except sandwiches...
- In Destroyermen, the crew of two US naval destroyers just happens to have some engineers who have worked in oil fields so that they can drill new oil wells for fuel. Other experts are in abundance (pilots that can design planes), to the point that know-how isn't usually a problem, just materials and facilities. Only once or twice does someone mention they don't actually know how to make something they need, but it's sort of shrugged off with "We'll figure something out."
- In the first novel, the crew of the Walker wants to capture a Grik ship to gather intel. Since 20th-century destroyers aren't designed for boarding actions, The Captain uses his interest in ancient naval warfare to get the Lemurians to build him a corvus, a bridge of sorts designed by Romans to drop on the enemy ship's desk and embed itself there with a spike, allowing boarders to cross. It works at first, but the corvus breaks under the strain, as the Lemurians make it out of bamboo.
- In the Prince Roger series, the Bronze Barbarians do have the basic knowledge required to teach their allies how to manufacture moderately advanced guns. Semi-justified in that the characters are all military personnel who were selected in part for having potentially useful skills outside the standard ones required for their post and that while they know the theory they often have to rely on native expertise for the actual details. Additionally several of them have skills that are never actually needed (for example one is a reformed carjacker and another knows how to knit).
- The 1632 series involves a Mysterious Event teleporting a self-sufficient town from West Virginia into 17th century Germany. The town has a library and a school, so plenty of books, a coal power plant with fairly large stocks of fuel from the parts of the nearby coal mine that came with them, and oil wells. With advanced knowledge, they are able to make down-leveled for the 21st century, but up-level for 17th century gear.
- Jules Verne's The Mysterious Island is pretty much entirely about this trope. In the book, a group of five Civil War era people, headed by an incredibly knowledgeable engineer, are trapped on an island in the Pacific. Within 4 years, they manage to re-create (at a small level) most aspects of 1860s technology while trapped on a deserted island, with (almost) no outside help. By the end of the book, they even manage to have a telegraph set up on the island.
- Done in Axis of Time, where there are hundreds (if not thousands) of "uptimers" (i.e. people from the 21st century) ending up in the middle of World War II. A number of them have hobbies that help in designing weapons and machines advanced for the time (but primitive for the uptimers). In fact, the uptimers are not able to replicate their own level of technology but merely upgrade what the 'temps already have with something from a few decades down the line. Instead of giving them a version of their own assault rifle that fires ceramic rounds and uses advanced electronic scopes linked with the HUD on the helmet, they instead make a version of the AK-47 fitted with an underslung grenade launcher. It also helps that they have computers aboard the ships with useful information in the cache (i.e. whatever people were downloading from the 'Net at the time of the Transition). Many people also get their hands on flexible tablets, but those cannot be replicated.
- Implied at the end of the movie The Time Machine (the 1960 original, not the remake). When Wells leaves after telling his friend Filby about his adventures, he takes three books from his vast library. Filby asks the housekeeper (and the audience), "If you were going to start civilization over again, which three books would you choose?"
- Averted in the flash-fiction story Rome Sweet Rome. A modern-day regiment of U.S. Marines are suddenly time-warped to ancient Rome. While initially having a huge military advantage against the Romans at first, due to their advanced technology, the marines quickly realize that without modern infrastructure they will be rendered helpless inside a few weeks (as their tanks run out of gas and as their guns run out of bullets), forcing them to consider negotiating with the Romans.
- The Time Traveler Essentials by Dinosaur Comics author Ryan North are there for preparing you for a situation in which this trope is needed.
- Portuguese sailors and traders who got stranded in Japan by a stroke of bad luck in the early 1500s brought primitive firearms with them. In less than a generation, the Japanese used their skills in metalworking to mass produce and to improve the primitive matchlock musket, such that some were nigh-impervious to rain. While two European empires fought with armies of roughly 20 000 men each at Rocroi in 1643, Japan could project over the sea to Korea 160 000 men, out of which over 40 000 trained musketmen, even 50 years before. Makes one wonder why weren't the Japanese the guys to sail the seas to Europe to conquer it back then.
- Japan had a population greater than that of France and a population density comparable to that of the Dutch Republic, i.e. lots concentrated in very small areas of farm-able land - that's just how wet-rice cultivation works out. At the time of Rocroi the Spanish Habsburgs' multiple monarchy (of Aragon, Castile, Sicily, Naples, Sardinia, Milan, Burgundy, Navarre etcetc) was supporting a force of some 500 000 regulars, militiamen and sailors across Italy, the Low Countries, Spain and both Americas.
- It's a question of power-projection. The Dutch East India Company (VOC) couldn't afford to try and hold Formosa (Taiwan) with more than a couple of thousand mercenaries. Successfully taking Korea would have, in any case, simply meant that the Empire of the Ming - possessed of five-to-ten times the population of the Japanese isles and an order of magnitude richer than them - would've been forced to spend a little more money buying firearms for their own troops, is all.
- And if you're still wondering, the Europeans and especially the British had by that time made several technical innovations to seafaring that meant that trans-oceanic deployments were a casual (though lengthy) cruise you would usually eventually come back from, whereas with Japan's 16th century naval technology setting out for Spain with 500000 regulars would have ended with you trying to take the Basque country with your remaining four guys with scurvy. Ships, clocks, and charts were what won Europe the world in the colonial age much more than muskets and cannon. Making it across the sea to mainland China was a bit of a feat of daring for 1600s Japan.
