Achievable Technology.

"But iron!"
"Hell, we're not savages, Devan, are we? When we came to this place we didn't revert back. We still have our minds. All we need is a blast furnace, some iron ore and a fire, isn't it?"

Jerry Sohl, Costigan's Needle

I've just finished re-reading my battered copy of Jerry Sohl's 1953 novel Costigan's Needle - I own the 1968 edition, so it's not as battered as it might be if I owned one of the original paperbacks.* I suspect I first read my mother's copy in my early teens, but I can't remember if I found the concept as unlikely then as I find it to be now.

For those of you unfamiliar with what Mr. Sohl considered to be his best novel**, the titular Dr. Costigan invents a device which creates an opening into another place, an opening which only allows the transmission of living matter. The device is damaged by angry Christian fundamentalists, and the resulting overload sends every living cell within a two-block radius into another world, sans clothing, shoes, glasses, fillings, pacemakers, and all of the other crutches for everyday life that technology has provided.

Naked and shivering, their first decision is to rebuild the device and return. Ten years later, they turn on the power to the new Needle and prepare to send everyone back through its Eye, only to discover that no one wants to leave.

Impressively, after ten years the inhabitants of Sohl's New Chicago have all the conveniences of life: steel for hammers, nails, and wire; glass for bottles, windows, glasses and light bulbs; plastics for dishes and insulation; tobacco and paper for cigarettes - and phosphorus for matches with which to light them. Their dentist fills teeth with gold and their doctors use ether as an anaesthetic, and their power plant provides the electricity for the new Needle.

I'm sorry, but I'm skeptical. Quick pop quiz: how many people reading this know how to make iron? We all know that glass is made out of sand - but how? It's got to be more complicated than just heating up some sand, or else there would be little glassy pits every time someone lit a fire on a beach. For that matter, if you were dropped naked into the woods, would you even be able to start a fire? How about building a cell phone and calling for help?

Now, I realize that Sohl has loaded the dice, in that the inventor of the Needle and a room full of scientists and technicians get transported, but even then I have to question the ability of 395 people to recreate enough of our civilization to be able to build log cabins that don't leak when it rains, let alone to the point of constructing complicated electronic devices. I strongly suspect that in reality all 395 of them would be involved in a constant struggle to get enough food on the table,with very little time left over to start figuring out the right impedance for a capacitor.

However, I must be the only person who feels this way. The something-from-nothing technological meme is fairly common in science fiction, with Mark Twain's A Connecticut Yankee in King Arthur's Court getting the ball rolling. All sorts of people seem to get transported or displaced into other dimensions or other times where their knowledge allows them to either revolutionize society or to build a new one from scratch, and a surprising percentage of these people know how to make gunpowder.

One of the more plausible amateur chemists is Calvin Morrison, the protagonist of H. Beam Piper's Lord Kalvan of Otherwhen. However, Calvin - or Kalvan - realizes immediately that he's not going to be able to convert the late-medieval society in which he finds himself into the equivalent of the industrial revolution in order to help them win a war. What he can do is to help them move about a hundred years further ahead: better gunpowder, rifled barrels, trunnions on cannon, and so on, which I find far more believable than having them build Sherman tanks.

Similarly, William R. Forstchen's "Lost Regiment" series presents one of the few "rebuild society from nothing" scenarios that worked for me. His characters are a shipload of Civil War soldiers whose ship gets swept out to sea and ends up going through a dimensional portal in the Bermuda Triangle. Forstchen loads his dice by having the ship loaded with a variety of useful military and engineering supplies, but even without that I'd accept the idea of a group of Civil War soldiers being able to start with almost nothing and recreate their society.

Why is that? I think that there's some kind of break point around the end of the 19th century after which the number of steps between phases of technology grows larger and larger. A miner in 1865 might well have known how to smelt down the ore, after he'd extracted it from the mine with pick and shovel. Or a blacksmith might have similar knowledge of what was involved with the ore before he began hammering the iron into nails. In current technology, the people who make the parts that are used to make the machines that make the parts for the machines that make the nails are unlikely to have ever seen the process of nailmaking, let alone have any idea of what iron looks like in its natural state.

The final joke for me is that if you sent 395 science fiction fans into another dimension, they might well do better than the average, just from having read so many variations on the theme. Oh, and the formula for gunpowder is 75% saltpeter, 15% sulphur and 10% charcoal. You might want to memorize that, just in case.
