  • Since nobody else has mentioned it:

    The (fictional) Ringworld is an immensely old mega-engineering project, requiring super-strength materials to put a habitable ring around a sunlike-star; a day-night cycle is provided by solar-collecting shadow squares in a smaller (thus faster-moving) orbit, connected by super-strength wire.

    This is an unstable arrangement, and requires repeated adjustments every century or so. Naturally, that system broke down (via capitalists grabbing the expensive fusion power plants for their own purposes) and the backup system was destroyed by a bioengineered weapon.

    The resolution to all this depends on psychic luck produced by evolutionary processes over the course of a handful of generations on Earth.

    Truly, “hard SF” means that enough details have been given that you can be sure it won’t work.



  • “Do you want to have a good time?” said a voice from a doorway.

    “As far as I can tell,” said Ford, “I’m having one. Thanks.”

    “Are you rich?” said another.

    This made Ford laugh.

    He turned and opened his arms in a wide gesture. “Do I look rich?” he said.

    “Don’t know,” said the girl. “Maybe, maybe not. Maybe you’ll get rich. I have a very special service for rich people…”

    “Oh yes?” said Ford, intrigued but careful. “And what’s that?”

    “I tell them it’s OK to be rich.”

    Gunfire erupted from a window high above them, but it was only a bass player getting shot for playing the wrong riff three times in a row, and bass players are two a penny in Han Dold City.

    Ford stopped and peered into the dark doorway.

    “You what?” he said.

    The girl laughed and stepped forward a little out of the shadow. She was tall, and had that kind of self-possessed shyness which is a great trick if you can do it.

    “It’s my big number,” she said. “I have a Master’s degree in Social Economics and can be very convincing. People love it. Especially in this city.”








  • Explanatory spoiler for those who don’t want to read Worm, a million words of deconstruction/reconstruction of superhero comics:

    spoiler

    The source of superpowers is a pair of gigantic multidimensional alien creatures. Their eternal mission involves finding a planet with intelligent life, infesting them with powers via brain tumor neural links, and encouraging them to fight so as to generate new ideas – the aliens are profoundly uncreative, even stupid by human standards, but immensely powerful – and when the planet is no longer producing, they reincorporate all the changed and combined powers, then eat the local sun to power their next FTL hop.

    When their experimental subjects aren’t moving fast enough, they open up their archive and resurrect the Endbringers – superpowered kaiju which provide a stimulus for cooperation by destroying cities on a schedule. Each Endbringer is unique. The Simurgh, or Ziz, takes the form of a giant statue of a woman covered in angel wings, and wings-on-wings, and so forth. Ziz has primarily psychic powers: telekinesis; a ‘scream’ or ‘song’ that drives people to violent insanity over the course of an hour or so; and mind-control that seems limited to slowly changing supers into creative serial killers and mad scientists and so forth. Ziz floats in orbit, preventing space travel, and periodically descends to the surface to terrorize a city.

    Everything escalates. Every trope is explained.









  • The history of technology teaches us that every non-trivial problem – and a large fraction of trivial problems – require specification beyond the bounds of conversational language.

    Greek geometers may have invented the idea of formalizing language with specific definitions, and inventing new symbols to represent special meanings. When important consequences accrue from getting things wrong, people develop jargon: knitters and sailors and shepherds and farmers; engineers and lawyers and plumbers. If you want to convey your knowledge and intentions, you can’t chat informally and expect a human to really understand what you want.

    For about a century now we’ve had devices that turn instructions into actions. Everyone who uses these becomes an expert in the particular form of instructions that the device needs, or else they don’t get what they want.



  • Grew up in fairly rural upstate New York, where you can expect lots of snow and you can unironically envy neighbors who have working Franklin stoves when the power goes out.

    I can confirm all of the above, plus: if you are lucky enough to have an Army-Navy surplus store around, one of your handmedowns is likely to be an N3B parka. Definitely not Russian or German or stylish. But it will keep everything above your thighs warm, except your hands. The pockets are uninsulated.
