It's all really evocative for me, but being a messy creative type rather than a physicist, I tend to think of this stuff in metaphorical terms. Like, say quantum to me and I'll brighten right up: "Oh! Connie Willis's story At The Rialto! She also did a story about Schwartzchild discovering black holes! Brilliant stuff!"
So anyway, here's a line I
symmetries are restored at high temperatures
lovelovelove. It's about the idea that at higher temperatures stuff tends to be better mixed up and uniform, like water looks the same on the molecule level no matter which direction you look at it, whereas in ice the molecules tend to line up in an orderly lattice and therefore will look different when viewed from different perspectives. Physicists use this idea to speculate about the Big Bang and how matter got distributed in/as the universe.
But isn't it a great tagline for a smokin' porn?
And to prove I am just as geeky about medicine:
1. "bone fusion," the point in arthritis at which pain disappears, because instead of rubbing against one another, the joint bones fuse together (not a story for the happyfic thing, I'm thinking), and
2. "cardiac ectopy," in which cells of a damaged or dying heart take on a rhythm and life of their own, independant of the overall controlling beat. Can be fatal.
I would love to see someone pick these up and write about them. Not sure I have the chops, yet.
